switcher (KVMS) are installed in the cabinet. This chapter
describes the structure of the SG7000 cabinet as well as the
structure and performance of the internal components.1.1Overview of
Cabinet

appearance, structure, technical specifications and features of the
cabinet.1.1.1Appearance of Cabinet The dimensions of the N68-22
cabinet are 2,200 mm (H) x 600 mm (W) x 800 mm (D). The usable
internal space height is 46 U (1 U = 44.45 mm). The weight of an
empty cabinet is about 130 kg. Figure 1-1 shows the appearance of
the cabinet. Figure 1-1 Appearance of the N68-22 cabinet Hardware

facilitate the wiring and bundling of the internal cables.The
N68-22 cabinet can be installed on the cement floor or in a room
with an antistatic floor. The N800 series support is used when the
cabinet is installed in a room with an antistatic floor.1.1.3N800

floor heights. The minimum floor height applicable for this type of
support is 100 mm. II. Introduction to Bracket and Slide Assembly
The bracket is used to support the floor around the cabinet, while
the slide to connect the cabinet with the support. Figure 1-4 shows
the appearance of the slide.(2)(1) (1) Hole for connecting the

Bracket and Slide Assemblies The number of supports can be
calculated using the formula of 2 x N. That is, each cabinet
independently uses one set of supports (2 supports), and a row of
cabinets (N cabinets) uses 2 x N supports.Each cabinet uses one set
of bracket and slide assembly, which is delivered with the
supports.Eachsetofbracketandslideassemblycomprisestwoslides,twolateral

cabinet needs two bracket fixing pieces, one front bracket, and one
rear bracket. Each row of cabinet also uses two lateral brackets.
If only one cabinet forms a row, two lateral brackets are also
needed.1.1.4Technical Specifications and Features of Cabinet Table

Cabinets According to the difference in component configuration,
there are two types of cabinets:
basiccabinetandextendedcabinet.Inadditiontothepowerdistributionboxand
frames,thebasiccabinetalsoaccommodatescomponentsliketheBAM,diskarray
cabinet,LANSwitch,andKVMS.Bycontrast,theextendedcabinetonly
accommodates the power distribution box and frames.1.2.1Basic
Cabinet The basic cabinet must be configured. Its internal
components include the BAM, disk array cabinet (optional), KVMS,
LAN Switch and frames. The basic cabinet provides such functions as
basic service processing, external interfaces (FE, clock, E1, and
so on) of the SG7000, and communication between the foreground and
background.The fixed configuration of the basic cabinet includes
one BAM, two LAN Switches, one KVMS, one or two frames, and one
direct current (DC) power distribution box. You can also configure
another BAM to form the dual-system mode. In this case, a disk
array cabinet is also needed. The weight of a basic cabinet with
full configuration is about 400 kg.Figure 1-5 shows the full
configuration of a dual-system basic cabinet.Hardware Description

1.3Components of
CabinetTheinternalcomponentsofthecabinetincludetheBAM,diskarraycabinet,LAN
Switch, cabling frame, KVMS, and DC power distribution box. This
section describes the specifications and features of these
components.1.3.1BAM
Note:Themanufacturer,model,andhardwareconfigurationoftheBAMservermaydiffer
from what are described here. In that case, the delivery prevails.
The description of this document is for reference only. The BAM is
a server of the operation and maintenance (O&M) system of the
SG7000. It acts as a bridge between the SG7000 and workstations.
The BAM forwards the O&M commands of workstations
(local/remote) to the host and redirects the responses of the host
to related O&M workstations. In addition, it stores and
forwards alarm information and service statistics data. You can
install one BAM or two as you like. The SG7000 adopts IBM X343
server as the BAM server, which is fixedly configured in the basic
cabinet.I. Appearance of IBM X343 Figure 1-7 is the front view the

This forms the ventilation mode in which air comes in from the

box in the lower part for heat dissipation. The fan box is made up
of plastic and sheet-metal. Each fan box contains six fans, which
are 119 mm wide and 32 thick. 2.2.1Function The system supports the
fan hot plugging function, temperature detection and speed
adjusting. You can control the speed of fans if the heat
dissipation and running situation are normal. You can know the
running situation of the components inside the fan box by observing
the indicator. You can also remotely maintain the fan box through
the NM terminal. 2.2.2Front View Figure 2-3 shows the front view.

6 and 8 in the front, the HBIU in slots 6 and 8 in the rear, the
HSCU in slots 7 and 9 in the rear (forming a pair configuration
with the HSYS), the ALUI in slot 16 in the front, and the CKII in
slots 13 and 14 or 15 and 16 in the rear (one CKII occupies two
slots).2)For the remaining slots, configure the SBPU in the front
slots and the SEPU in the corresponding rear slots according to the
system capacity. You need to configure blank panels for slots not
configured with boards.3)If the system supports broadband services,
you need to configure the SBPI in slots 4 and 11 in the front and
the VIEB in corresponding slots in the
rear.4)Toensuresystemreliability,configuretheHSYS,SBPI,andCKIIinthe

chapter describes the classification of the boards of the SG7000
and the functions, technical specifications, interfaces,
dual-in-line package (DIP) switches, and jumpers of each
board.3.1Board ClassificationThe SG7000 has 12 kinds of boards,
which roughly fall into 3 categories according to their positions
in the frame:Front boards (5 kinds) Back boards (5 kinds, excluding
UPWR) Subboards (2 kinds)
Thefrontboardsaremainlyserviceprocessingboardsandcontrolmanagement
boards,whilethebackboardsaremainlyinterfaceboardsprovidingE1andT1
interfaces and 100-Mbit/s Ethernet interfaces. All the front boards
and back boards are hot-swappable.The subboards mainly provide
external interfaces and process signaling system No.7 (SS7)
links.The front boards and back boards are used in pairs. See Table

is the monitoring board, inserted in slot 16 of the frame.It has
the following functions: Connected with the equipment management
board through the master and slave serial port cable, reporting the
collected information, receiving the commands from the equipment
management board, and controlling the indicator activities.
Monitoring the cabinet temperature and sending it to the equipment
management board through the master and slave serial port cables.
Collecting the fault detecting signal and in-service signal of four
power modules through the serial port cable imbedded in the
backplane, generating work status
fromthesignals,reportingthemtotheequipmentmanagementboardthrough
master and slave serial port cables, and indicating the work status
and in-service status of the power board through
