Checking Power-on/Power-off of BTS

Purpose To ensure BBU and RRU can work normally. Procedure (BBU) 1.

2.

Power-on Procedure: 1.

Plug out all of the boards of B8200 carefully, and keep the PM (power module) in the slot.

2.

After the BTS is powered on, check whether the “RUN” indicator of the PM module is ON, and the “ALM” indicator is OFF.

3.

Check whether the FAN module is running normally (the “PWR” indicator is ON, and the “ALM” indicator is OFF. If the FAN module is in normal operation, please insert the CC, BPC, UBPG, FS and SA one by one.

Power-off Procedure:

ZTE Confidential Proprietary

15

ZXSDR BS8700 Step by Step Commissioning Guide

1.

Shut down the power supply system directly.

Reference After the PM module or any board is just powered on, the “ALM” indicator flashes, which shows the board has not been started. If the SA board is not inserted, the “ALM” indicator on the FA panel will be ON. Hot plug-out/in of the power cables is forbidden. The handle bar on the left of a board has three gears, and that on the right is fixed. Please gear the handle bar to the outmost before plugging out the board, and gear the handle bar to the inmost before plugging in the board. To remove the fan subrack, firstly please push the lock-switch on the panel on the right before plugging out the fan subrack. Procedure (RRU) 1.

Power-on Procedure: 1.

2.

Special power cables have been delivered together with the RRU to connect with -48VDC power cabinet or AC power cabinet. Please ensure the power cables and PGND cables are correctly connected before using the fuse.

Power-off Procedure: 1.

Shut down the power supply of RRU:



When the RRU is installed indoors, switch off the RRU air-switch of the AC/DC power distribution box;



When the RRU is installed outdoors, switch off the RRU air-switch of the indoor/outdoor DC lightning protection box;

Note: After all of the above procedure, the BTS commissioning engineer should feed back the BTS status to the iBSC&RNC commissioning engineer, who will then conduct version upgrade and data synchronization accordingly. Follow-up operations are not allowed until the iBSC&RNC commissioning engineer completes the job and sends a notice. Ensure that the iBSC&RNC has finished BTS version upgrade and data synchronization before the subsequent procedures.
