WARNINGTo prevent electrical shock, do not install equipment in a wetlocation or during a lightning storm.
CAUTIONElectronic modules can be damaged by static electrical discharge.Before handling modules, wear an antistatic discharge wrist strapto prevent damage to electronic components. Place modules inantistatic packing material when transporting or storing. Whenworking on modules, always place them on an approved antistaticmat that is electrically grounded.
Unpacking and Inspecting the ChassisEach Total Access 3000 chassis is shipped in its own cardboard shipping carton unless it was ordered as a fully racked system. Open each carton carefully and avoid puncturing the carton with sharp objects. After pulling the chassis out of the carton, remove the foam endcaps and slip the chassis out of the cardboard shipping sleeve and protective plastic bag.
After unpacking the unit, inspect it for damage. If damage is found, file a claim with the carrier, then contact ADTRAN Customer Service. For more information, refer to Appendix A, Warranty.4 61181001L1-5E

InstallationMounting Bracket OrientationThe Total Access 3000 Chassis comes with mounting brackets that can be mounted with the flanges facing forward or backward in two different locations on the chassis sides providing either flush-mounting or mid-mounting. Attaching the mounting brackets to the chassis requires four screws on each side, and are supplied with the unit.
NOTEBefore installing the chassis in the Central Office frame the paintmust be removed and an antioxidant applied to the surfaces of themounting brackets that come in contact with the frame. This willensure electrical continuity between the Total Access 3000 Chassisand the CO frame.
Flush-mountingFor flush-mounting, use a #2 phillips-head screwdriver and attach the mounting brackets to the Total Access 3000 Chassis with the flanges facing rearward on the front mounting holes.
Mid-mountingFor mid-mounting, use a #2 phillips-head screwdriver and attach the mounting brackets to the Total Access 3000 Chassis with the flanges facing forward on the front mounting holes.
Installing the ChassisAfter attaching the mounting brackets to the Total Access 3000 Chassis sides, use the appro-priate screws for the Central Office rack type and mount the chassis in the rack as follows:
Flush-mountingFor flush-mount systems, the Total Access 3000 must be mounted from the rear of the rack, with mounting bracket flanges facing rearward.
Mid-mountingFor mid-mounting the Total Access 3000 must be mounted from the front of the rack, with the mounting bracket flanges facing forward.
NOTEOther orientations will require either mounting from the front orrear, and depend on the rack type installed in the CO and thestandard operating procedures established by the CO.
Once the orientation of the chassis has been determined, use the four appropriate screws for the CO rack and an appropriate screwdriver and secure the Total Access 3000 Chassis in place on the rack.61181001L1-5E 5

Total Access 3000 23-Inch Chassis Installation and Maintenance PracticePOWER CONNECTIONSThe backplane contains all I/O connectors, control signal routing, and power routing, as well as all necessary interconnections between access modules, the multiplexer cards and the System Controller Unit (SCU). No wire wrapping for network or loop connections is necessary for normal chassis operation. Additional wire-wrap terminals on the backplane accommodate special modes, such as metallic loop testing and external alarm input. Detailed wiring diagrams are provided later in this practice.
All permanent connections to Total Access 3000 Chassis are made on the backplane. Figure 2 illustrates the backplane and Figure 3 indicates the location of the power and ground connec-tions.
Frame Ground ConnectionThe frame ground lug, located on the lower left corner of the backplane, can accommodate from 8 to 14 AWG wire. When connecting the frame ground, use a wire gauge that is at least as heavy as the power wiring.
NOTEThe ground wire exiting the chassis must be terminated with a ULListed grounding lug. The grounding lug must be a two-hole lug ora one-hole lug that is used in conjunction with an anti-rotationdevice. The surface of the lug that connects to the frame shall becleaned and an antioxidant applied. The same shall be done for thesurface of the frame or bus where the connection is to be made. Anapproved thread-forming screw shall be used to connect the frameground connector to the frame or bus.6 61181001L1-5E

Total Access 3000 23-Inch Chassis Installation and Maintenance PracticeFigure 3. Total Access 3000 Power Connections
To make the frame ground connection to Total Access 3000 Chassis, perform the following steps:
1. Using an appropriate crimping tool and lug, fasten the lug to the ground wire.
2. Locate a nearby grounding screw on the equipment rack.
3. Secure the ground wire to Frame Ground using the lugged end of the grounding wire.
4. Cut the ground wire length to reach from the grounding lug on the rack to the Total Access 3000 Chassis grounding terminal, located on the lower left corner of the backplane. Leave enough slack to allow for tying to the rack, if required.
5. Using wire strippers, strip 5/8 inches of insulation from the grounding wire.
6. Insert stripped end of the ground wire into the copper Total Access 3000 grounding terminal.
7. Tighten the ground connection securely with a straight-slot screwdriver.
Test Frame Ground ConnectionTo ensure a good ground, use a multimeter to check continuity between the frame grounding lug and the rack grounding strap at the top of the rack. With the multimeter set to its lowest resistance range, if applicable, place one lead on the racks ground strap and the other lead on the Total Access 3000 Chassis frame ground terminal. The reading should be 1 or 2 ohms. Greater readings should be investigated.
NOTEThe Ethernet port, Dual and Quad BNC ports, composite clockports, and any DSX-1 port must only be connected to intra-building wiring.

Power ConnectionsPower Connection
NOTEConnect to a reliably grounded 48 VDC source that is electricallyisolated from the AC source.
NOTEA readily accessible disconnect device, such as a rack mount fuseand alarm panel that is suitably approved and rated, should beincorporated in the fixed wiring.
Dual power buses are provided with separate battery returns. Power connections use two separate opposing blocks, labeled TS1 and TS2, located on the lower left side of the backplane below the Pair 5 amphenol connector (see Figure 3). The terminals are on 0.4375 inch centers and allow for wire gauges up to 10 AWG. There is a separate Frame Ground terminal, labeled FR GND, located on the bottom left side of the backplane, and can accommodate up to 8 AWG wire. The two power inputs, TS1 and TS2, are identical in function and can be used for redundant power configurations. The Frame Ground terminal routes to mechanical contact points and provides an electrical connection to the chassis metalwork. The two power buses and Frame Ground route to all the cards in the chassis. Plug-in cards are responsible for any necessary DC-DC conversion.
Figure 4 depicts how the Total Access 3000 Chassis can be powered from a typical dual-feed fuse and alarm panel. Seven shelves are depicted. The number of shelves that can be placed in a 7-foot central office rack depends on the type of service deployed, the number of access modules in the chassis, and, in the case of HDSL or T1, the number of repeaters being powered.
After connecting and checking the ground to the Total Access 3000 Chassis, connect power to the chassis. Check to make sure the power source is providing the correct power and polarity to the chassis. To connect power to the chassis, perform the following steps:
1. Determine which fuse pairs are to supply power to the Total Access 3000 chassis.
2. Remove the fuses from the A and B slots for the pair determined in the above.
3. Using a #1 phillips-head screwdriver, remove the Plexiglass cover to the power terminals, labeled TS1 and TS2.
4. Cut four lengths of AWG 10 wire to reach from the terminals on the fuse and alarm panel to the power terminals on the Total Access 3000 Chassis. Be sure to include enough length to allow for tying the wire neatly to the frame as specified by CO SOP.
5. Using the crimping tool, connect an appropriate lug to each end of the wires.
6. Using a screwdriver appropriate for the fuse and alarm panel terminals, and a straight slot screwdriver for the Total Access 3000 Chassis power terminal, connect the ends of one wire between the A CO 48 VDC supply and the 48 VDC 48 PRI terminal on the Total Access 3000 backplane. Secure the wire to the backplane with wire tie through the tie anchor.61181001L1-5E 9

Power Connections7. Connect three more power wires, connecting the A CO 48 VDC return with TS1 48 VDC RET; B CO 48 VDC supply with TS2 48 VDC 48 SEC; and B CO 48 VDC return with TS1 48 VDC RET. Secure the wires to the backplane with wire tie through the tie anchor.
NOTESee Figure 4 for an example of multiple shelves powered by a singleequipment bay fuse panel.
Apply Power and Check VoltageBefore proceeding further, ensure that power has been correctly applied to the chassis. The proper voltage to Total Access 3000 Chassis is 48 VDC, with an operating range of 42 VDC to 56 VDC.
WARNINGInstalling fuses in the fuse alarm panel at this stage will providepower to the chassis. There will be power to pins on the backplaneand inside the chassis. Exercise caution to avoid electric shock.
NOTEThe branch circuit overcurrent protection shall be a fuse or circuitbreaker rated for 48 VDC at 20 amps. Include the appropriateinput current rating for the product.
1. Install the 20 amp fuses in the slots in the fuse and alarm panel that service the Total Access 3000 Chassis.
2. Using a voltmeter, place the common (normally black) lead on the TS1 48 VDC RET terminal and the DC volts (normally red) lead on the TS1 48 VDC 48 PRI terminal. The reading should be in the operating range of 42 VDC to 56 VDC, with a nominal value of 48 VDC. Note the polarity.
3. Using a voltmeter, repeat step 2, using the TS2 48 VDC RET terminal and the TS2 48 VDC 48 SEC terminal.
4. Remove the fuses from the fuse and alarm panel slots, securing power to the Total Access 3000 Chassis.61181001L1-5E 11

Total Access 3000 23-Inch Chassis Installation and Maintenance PracticeDATA CONNECTIONS
Removing Rear Plastic GuardsThe large rear Plexiglass guard covering the backplane is a safety feature of the Total Access 3000 designed to keep personnel and equipment from contacting potentially high voltage exposed at some backplane locations. Following the sequence of steps outlined in this practice will allow the service provider to remove the guards once, make all the necessary Total Access 3000 Chassis backplane connections, and then reinstall the guards. To remove the guards, perform the following steps:
1. Using a #1 phillips-head screwdriver, remove the long, thin Plexiglass guard covering the wire-wrap terminals at the bottom of the backplane. It is held in place with two screws.
2. Carefully remove the guard by pulling it straight from the backplane.
3. Using a #1 phillips-head screwdriver, remove the four screws holding the large guard in place.
4. Carefully remove the large guard by pulling it straight back from the backplane.
NOTEWire tie anchors are pre-installed on the Total Access 3000 Chassisbackplane to secure the 64-pin amphenol connectors. It is easier tothread the wire ties through the anchors while the backplaneguard is removed. ADTRAN recommends using the wire tiesprovided to secure the amphenol connectors. Thread the wire tiesthrough the anchors at this time, with the guard removed.
Wiring ClocksThe Total Access 3000 Chassis accepts either BITS or composite clock inputs from an external timing source. When deployed as a DSLAM system, an optional Stratum 3E Clock Module (P/N 1181930L1) can be used as a timing source that provides a backup clock signal. The module works in conjunction with the DS3 Cell Switch Module (CSM) to provide holdover capability upon the loss of the primary timing source, typically an external DS1 BITS clock. As an Office Repeater Bay deploying HDSL or T1, no clock input is required. As an Office Repeater Bay deploying ISDN, a composite clock input may be used. Future services may require these or other clock inputs; the Total Access 3000 Chassis can accommodate them.
Connect 64 kHz Composite ClockAn external composite clock input may be used when deploying ISDN from Total Access 3000 Chassis. To wire an external composite clock to a single Total Access 3000 Chassis, perform the following steps:
1. Determine the +, and drain or ground wires from the CO clock source.
2. Using wire strippers, strip 1 to 1-1/2 inches of the insulation from the end of the clock source twisted pair, shielded, drop wire.12 61181001L1-5E
-
Data Connections3. Using the wire-wrap tool, wire wrap the + wire from the clock source to the pin marked + on connector P10, EXTCLK A-IN.
4. Wire wrap the wire from the clock source to the pin marked on connector P4, EXTCLK A-IN.
5. Wire wrap the drain or shield wire from the clock source to the pin marked S on connector P4, EXTCLK A-IN.
NOTEIf the drain or shield is connected to the clock source, then thedrain or shield does not need to be connected to the S pin of P4.
6. Tie the clock source wire neatly to the frame.
7. On the daughterboard mounted to the left of, and slightly below, P4, move the jumper so that the left two pins labeled TERM IN, are connected together.
Up to eight Total Access 3000 Chassis may be daisy chained to a single output from the timing source, so only one wire run is required from the timing source for an installation of up to eight Total Access 3000 Chassis. Use wire of the same type as was used for the wire run from the CO clock source to the Total Access 3000 Chassis. To connect up to eight Total Access 3000 Chassis to a single external timing source, perform the following steps:
1. Determine the length of wire required to run from the first chassis, connector P4, to the second chassis, connector P4, that is to be wired in the same daisy chain. Leave approxi-mately 1 to 1-1/2 inches for wire wrapping.
2. Using wire strippers, strip approximately 1 to 1 -1/2 inches from both ends of the wire run.
3. Using a wire wrap tool, wire wrap the +, and drain wires to the +, and S terminal pins of connector P4, A-IN, on the backplane.
4. Run the wire from P10 on the source shelf to connector P4, EXTCLK A-IN, on the receiving shelf.
5. Wire wrap the +, of the wire run to the +, terminals of P4 on the receiving shelf.
6. On the daughterboard of the receiving shelf, mounted to the left of, and slightly below P4, move the jumper so that the right two pins, labeled TERM OUT, are connected together.
7. Repeat steps 1-6 for each Total Access 3000 Chassis, up to a total of eight in the daisy chain, that is to be interconnected on the single CO timing source.
NOTEIn any daisy chain of Total Access 3000 Chassis using a singletiming source, only the first shelf in the chain should have thetiming daughterboard jumpered to TERM IN. All the remainingchassis in the chain should have the daughterboard jumpered toTERM OUT.61181001L1-5E 13

Total Access 3000 23-Inch Chassis Installation and Maintenance PracticeWiring to MDF (TDM)The Total Access 3000 delivers services out to the customer loops via 64-pin amphenol connectors on the Total Access 3000 Chassis backplane in the same manner that it receives its DSX-1 input from the DSX cross-connect panel. The one exception to this rule is the delivery of optical fiber froma fiber based access module. Deploying either HDSLx or T1 requires the connection of two amphenol connectors. To take maximum advantage of ADTRANs capability to deliver ISDN out to the customer, five amphenol connectors are required.
To connect amphenol connectors to the Total Access 3000, perform the following steps:
1. Noting the orientation of the backplane male connection receptacle, push the female cable connector onto the backplane connector.
2. Using a small straight-slot-head screwdriver, snug the screw on the right side of the cable connector into the hole provided on the backplane connector. Secure the connector into place on the left side by tightening the wire tie around the body of the cable connector.
3. Using a side cutter, snip the wire tie end off flush with the barrel of the tie.
4. Repeat steps 1-4 for each connector on the backplane being used for the intended application.
5. Neatly tie off the data cables to the left of the shelf.
NOTEAll data cables should exit the Total Access 3000 Chassis to the left(as viewed from the rear), and be neatly tied to the frame as per COSOP. Other wiring (i.e., power, loop test access, clock, externalalarms, etc.) can exit either right or left and be tied off to the frame.
The ground wire, attached to J33 on the backplane, should be routed to the nearest suitable grounding point.
Refer to the Installation and Maintenance Practices for the access modules being deployed, for a full description of the different Total Access 3000 loop assignments and pinouts.
Wiring to MDF (DSLAM)The Total Access 3000 Chassis is designed to be a DSLAM as well as a TDM platform. With the use of a Cell Switch Module or Ethernet Switch Module in Slot A and/or Slot B and multiport access modules, the Total Access 3000 can deploy up to the following number of circuits:
14 DS3 circuits
28 OC-3c circuits
112 DSX or E1 circuits
224 xDSL circuits
Refer to the Installation and Maintenance Practices for the access modules being deployed, for a full description of the different Total Access 3000 loop assignments and pinouts.18 61181001L1-5E

Data ConnectionsConnecting the High-Speed Metallic InterfaceIn addition to the individual DSX inputs from the network available via the Loop connectors on the backplane, when the Total Access 3000 is employing a multiplexer module in either slots A or B (or both), the shelf has the ability to take its TDM or ATM input from the multi-plexer. For the metallic high speed interfaces DS3 (ATM or TDM) and STS-1, the input from the network is via coaxial cable through a special coaxial adapter mounted to the lower right corner of backplane labeled J34.
The Total Access 3000 Chassis becomes a multiplexer shelf, with the ability to direct any DSX in the DS3 or STS-1 payload to any slot in the shelf for whatever service is being provided to the customer. The Total Access Cell Switch Module (CSM) can interface with the ATM network via a DS3 connection also utilizing coax cable.
Installing the High-Speed Connector ModuleThe high-speed metallic interface is a special coaxial adapter mounted to the lower right hand corner of the backplane. It is a separate part not required for individual DSX-1/E1 network inputs. To install the high-speed metallic interface to the Total Access 3000 Chassis, perform the following steps:
1. Carefully line up the two guide pins on the adapter with the holes on the ends of the 24-pin female connector on the backplane. Lining up these pins and holes will align the screw holes in the adapter module with the threaded press fittings in the backplane.
NOTEThe 24 pins on the underside of the adapter module must line upwith the 24-pin female connector on the backplane. Do not forcethe adapter into place.
2. Carefully press the adapter into place on the backplane socket.
3. Using a #1 phillips-head screwdriver, secure the adapter to the backplane with the two screws provided.
Connecting High-Speed CablingAfter attaching the high-speed metallic interface to the backplane, data cabling must be installed from the network to route the high speed signal to the Total Access 3000 chassis. To connect the high-speed cabling to the high-speed metallic interface, perform the following steps:
1. Determine which cable from the network is for transmitting and which is for receiving.
2. Attach the network transmit cable to the Total Access 3000 upper BNC connector, labeled RX. The fitting is a standard BNC connector. Align the outer ring of the cable connector with the keys on the chassis connector barrel, press the cable in, and turn approximately 1/3 turn clockwise to the locking point.
3. Attach the network receive cable to the Total Access 3000 Chassis lower BNC connector, Labeled TX. The fitting is a standard BNC connector. Align the outer ring of the cable connector with the keys on the chassis connector barrel, press the cable in, and turn approximately 1/3 turn clockwise to the locking point.61181001L1-5E 19

Alarm ConnectionsConnecting Alarm OutputsDepending on the vendor equipment employed at the CO, wiring external alarms from the Total Access 3000 Chassis will vary slightly. The important consideration is whether the external alarm equipment requires a Normally Open (NO) or Normally Closed (NC) circuit to pass an alarm. After determining what the CO equipment requires, connection can be made to the equipment from the Total Access 3000 Chassis, see Figure 9 for location of alarm contacts. To connect alarm outputs to the Total Access 3000 Chassis, perform the following steps:
NOTEEach three-pin alarm header is wired the same way for thespecified alarm.
1. Determine whether the external alarm reporting device uses a normally open or normally closed circuit for alarm relay.
2. Using standard telco cross-connect wire, determine and cut the length required to reach from the alarm headers to the alarm-reporting device.
3. Using wire strippers, strip 1 to 2 inches from both ends of the wire.
4. Using a wire-wrap gun, wire wrap one strand to the center pin (common) from the Total Access alarm relay header, and the other strand to either the NO (normally open) or NC (normally closed) pin on the relay header.
5. Connect, using wire wrap or lugs, as appropriate, the two wires to the appropriate terminals on the external alarm relay device being used.
NOTEThe AUX NO/C/NC alarm contacts are reserved for future use.
Connecting Miscellaneous Alarm InputsThere are three additional external alarm inputs that can be reported to the SCU on the Total Access 3000 chassis. These are labeled ACO, RMT and AUX2 (if AUX1 is being used for the fan alarm), see Figure 9. Each functions in an identical manner to the fan alarm. Terminal B supplies a 48 VDC source. Terminal A expects 48 VDC if an alarm condition exists on the alarmed equipment.
To connect an external alarm input to the chassis, perform the following steps:
1. Choose an alarm header set from the EXT INPUTS block, P22, on the middle bottom of the Total Access 3000 backplane.
2. Using standard telco cross-connect wire, determine and cut the length required to reach from the alarmed piece of equipment to the header chosen. Allow length for 1 to 2 inches of stripped wire for wire wrap, and neat routing out from the Total Access 3000 Chassis.61181001L1-5E 21

Total Access 3000 23-Inch Chassis Installation and Maintenance PracticeNOTEOmit step 2 if the alarmed piece of equipment has its own source of48 VDC and does not need the 48 VDC feed from the TotalAccess 3000 chassis. The Total Access 3000 chassis expects to see48 VDC on pin A of the alarm pair when an alarm conditionexists.
3. Using wire strippers, strip 1 to 2 inches from both ends of the wire.
4. Using a wire-wrap gun, wire wrap one wire to the B pin of the Total Access 3000 AUX1 header (P22), and the other end to the alarmed unit alarm terminal marked B.
5. Wire wrap one end of the second wire to the A pin of the Total Access 3000 Chassis AUX1 header (P22) and the other end to the appropriate equipment alarm terminal.

Network Management ConnectionsNETWORK MANAGEMENT CONNECTIONSThe Total Access 3000 Chassis integrates onto the backplane several different management ports to allow for remote management of the shelf, see Figure 10. The management interface is on the System Controller Unit (SCU) discussed in detail in the Section 1, System Description in the Total Access 3000/3010 System Manual, P/N 61181001L1-1).
Depending on the selected system SCU, one of the following methods can be used to connect to the system: NMA over TL1 on an X.25 network, SNMP over Ethernet, or Telnet from a remote location.
Also, regardless of SCU selection, up to 32 shelves can be linked together on the RS-485 bus for management of those shelves from a single management interface.
Figure 10. Total Access 3000 Management Ports
Connecting the RS-485 Bus Between ShelvesUp to 32 shelves can be linked together for management from a single shelf designated as host (the other shelves will be configured as clients). This feature allows conservation of valuable external management ports within the CO, and provides local or remote management for up to 32 shelves from the craft interface on front of the host SCU, or from the remote management port connections described in this section. To connect the RS-485 bus between shelves, perform the following steps:
1. Determine and cut the length of wire necessary to reach from the RS-485 wire-wrap header, P2, in the first shelf in the chain to the RS-485 wire-wrap header, P2, in the sec-ond shelf. Remember to allow for stripping the ends of the wire, routing the wires out to the right side of the shelf to the frame, and tying down in accordance with CO SOP.

Total Access 3000 23-Inch Chassis Installation and Maintenance Practice2. Using the wire-wrap tool, connect the shielded, twisted pair interconnect wire to the RS-485 wire-wrap header, P2, on the host Total Access 3000 backplane. Connect the two conductors to the A and B Out pins, and the shield or drain wire to the Out ground pin.
3. Run the interconnect wire to the backplane of the first client shelf. Using the wire-wrap tool, connect the two conductors and ground of the interconnect wiring to the RS-485 wire-wrap header, P2, on the backplane of the client shelf. The two conductors will be wired to the A and B In pins, and the ground or shield wire will be cut without connecting to the ground pin. Note that only one end of the grounding wire should be connected between the two shelves. Take care to connect the A pins of each shelf together, and the B pins together. Do not cross the polarities.
4. If there are more shelves to be connected, repeat steps 1 through 3 for each shelf to be added to the chain. Disregard the designation of host and client for additional shelves. Each shelf after the first will be a client shelf on the daisy chain. It is important to note that there is only one shelf designated as host on any daisy chain of up to 32 shelves and that the host is on the end of the chain.
Figure 11 illustrates the connecting of the RS-485 bus between shelves.

-
Total Access 3000 23-Inch Chassis Installation and Maintenance Practice6. Connect the other end of the cable to the modem configured as described above.
7. Connect the modem to POTS line as required by the manufacturer.
NOTETo complete the connection to the Total Access 3000 Chassis, theTotal Access 3000 must now be called from a PC configured as aVT100 terminal with communication software.
Connecting the X.25Total Access 3000 can send and receive TL1 commands for NMA management over the X.25 packet switched network. The Total Access 3000 Gateway SCU has a built-in X.25 PAD, and the shelf is ready to connect to the network. Access to the network is via an RS-232 connector (J30), labeled NTWK MGMT, located on the lower right side of the backplane. To connect the X.25 to the Total Access 3000, perform the following steps:
1. Connect the DB-25 data cable male connector to the NTWK MGMT port, J30, on the Total Access 3000 backplane.
2. Connect the other end of the data cable to the designated port of the X.25 switch.
NOTEThe CO X.25 network administrator must configure the X.25switch for the Total Access 3000 Chassis, accomplishing taskssuch as assignment of an LDN number for the shelf.
NOTEIt is possible to remote the X.25 interface over a DDS line of up to64 kbyte capacity, with the network designer designing the specificinterface. Some smaller COs without an X.25 switch may desire totake advantage of this capability.
Connect 10Base-TTotal Access 3000 can provide SNMP management capability over Ethernet. The Total Access 3000 Gateway SCU has a built-in Ethernet interface, and the shelf is ready to connect to the network. Access to the network is via an RJ-45 10Base-T connector (J32), labeled E-NET, located on the lower right side of the backplane under the Pair 8 connector.
NOTEADTRAN recommends that the Total Access 3000 shelves not bedaisy-chained when using SNMP. For this configuration, each shelfmust be connected to an Ethernet hub.26 61181001L1-5E

SCU, Multiplexer, CSM, and Access Module InstallationTo connect the Total Access 3000 Chassis to the Ethernet ring, simply plug the male RJ-45 modular connector into the female RJ-45 port on the Total Access 3000 backplane. When planning the cable run to the Total Access 3000 Chassis, be sure to allow enough cable for routing the cable from the backplane connector to the frame, and for neat tie-off in accordance with CO SOP.
SCU, MULTIPLEXER, CSM, AND ACCESS MODULE INSTALLATIONThe manner in which the Total Access 3000 functions is totally dependent on the modules that are placed into the System. For information on specific module functionality, refer to the Total Access 3000/3010 System Manual (P/N 61181001L1-1).
Unpacking and Inspecting ModulesEach module is shipped in its own cardboard shipping carton. Open the carton carefully and avoid puncturing the carton with sharp objects. After removing the unit from the carton, unwrap the bubble-wrap and pull the unit from the antistatic plastic bag.
After unpacking the unit, inspect it for damage. If the equipment has been damaged, file a claim with the carrier and then contact ADTRAN Customer Service.
Installing ModulesThe SCU must be placed in the slot labeled SCU. Multiplexer or Cell Switch Modules must be placed in either the slot labeled A or B. Access modules must be placed in any of the 28 slots, labeled 1 through 28. Gently but firmly push the module into the desired slot of the chassis. Simultaneous thumb pressure at the top and bottom of the unit will ensure a good seat of the modules pins into the backplane connector. Push the ejector tab up and closed against the front panel of the module. Use the documentation shipped with the individual module to verify the proper sequence of LED illuminations.
NOTEAny slots that are not occupied by an access module must becovered with a blank front panel. The part numbers for these arelisted below:
Slot A or B 1181952L1
Slots 1-28 1181953L1
