Observe the general safety precautions against personal injury and equipment damage outlined in the regional Installation Safety Manual at all times.
Connections will be made on the Rectifier shelf Controller board. With this in mind, all POWER must be removed from the BTS (both AC and DC via Battery Disconnect).
Cell phone communications may not be possible once power is removed. Ensure there is an alternate means of communication with the OMC-R technician.
3.2 Preparations
It is strongly recommended that this method be read in its entirety before starting the operations presented herein.
Prior to starting the operations presented in this method, arrange all materials, tools, and test equipment at the work location to minimize site outage duration and maximize efficiency.
If sign-offs on procedures in Section 4.0 are customer required, the field technician/customer must place a mark after the completion of each step in the Cust and/or NT block indicating that the step has been completed.
3.3 Check List
Verify the following items have been received and/or accomplished before proceeding with the procedure.
This procedure has been reviewed before kit installation,
The Alarm Temperature Kit (V2) is delivered (NTQA68JB),
Modification of the Alarm Criteria is performed at OMC-R, if not, ask to OMC-R technician to follow the procedure "modification of alarm criteria" in Appendix A – on page 45.
The information presented in this method covers the following topics:
• Preliminary Checks
• Site Shutdown and Cabinet(s) Power-off
• Installation in a BTS 12000 Outdoor Equipped with GIPS
• Installation in a BTS 12000 Outdoor Equipped with Mitra/Philips

4.2 Preliminary Checks
These procedures describe the initial checks to perform before any operations.
The BTS S8000 Outdoor or S12000 Outdoor is on line.
Procedure 1 – Preliminary Checks (Page 1 of 2)
Step Action Observation
1 Upon arrival, read the safety guidelines specific to the site.
2 Set up a phone link with the OMC technician and inform him that alarms will appear when opening the radio cabinets front doors.
3 Before opening the doors, make sure that no water is located above the BTS doors, or roof. If so, wipe it off with a sponge or a duster to avoid any water from falling into the BTS when opening the doors.
The objective of this procedure step is to power-off the cabinet(s)..
4 Open the cabinets front doors and manually engage the door holding of each radio cabinet.
CAUTION/WARNING: The door holding mechanism (stop bar) must be manually engaged while the doors are open to hold the doors in one of several pre-determined open positions to prevent the possibility of damage to personnel or equipment.
See Figure 1.
Figure 1 – Door Holding Mechanism
5 Visually check the operating status of the site. - active CMCF: RDY, RUN, ABIS and ON green LEDs on,- passive CMCF: RDY, RUN green LED on,- no alarm on any CPCMI (if a CPCMI card is connected to only one external PCM, a NOS alarm will illuminate a red LED on its front face).- RECAL board for each BTS cabinet has the +5V and RDY green LEDs on.
CAUTION/WARNING:Powering down the equipment stops call processing for the sector or site until power is restored.
Procedure 2 – Site Shutdown and Cabinet(s) Power-off (Page 1 of 5)
Step Action Observation
1 Ask the OMC-R technician:
• To unmask the External alarm number 15 for the base cabinet, alarm 31 for the extension 1 (if present) and alarm 47 for the extension 2 cabinet (if present),
• To change label of these external alarms with the string "Cabinet Extreme Ambient Temperature Signal (CEATS) Base/Extension1/Extension2 cabinet"
Refer to NTP (411-9001-128) - OMC-R User Manual
CAUTION/WARNING: This step is MANDATORY and applicable for each cabinet present on site
Note: The installation of the Alarm Temperature Kit prevents the use of external alarm number 15 for the base cabinet, alarm 31 for the extension 1 and alarm 47 for the extension 2 cabinet for all other applications.
2 If you want to check the inverter and the alarm functionality, perform the Procedure B in Appendix B – on page 47.If not, go to step 3.
3 Ask the OMC-R technician to interrupt the BTS traffic by performing a soft shutdown.
See Sheet LO2
If the BTS is chained or looped
4 Ask the OMC-R technician to interrupt the traffic of each dropped BTS by performing a soft shutdown.
See Sheet LO2 (DRX locked)
5 Visually check that the LEDs 'RDY' on the CMCF board is in OFF position.
6 Remove the blue straps on the CPCMI board and make a short circuit.
