1.1.3 Installation Preparations

1)
Wear the anti-static wrist strap and gloves and make the grounding terminal well
grounded.
2) Before a board is installed, take the board out of the anti-static packing box (do
not touch the surface of the printed circuit board) and check whether there is any
damage or deciduous element.

1.1.4 Installing a Board

1)
Locate the slot that the board is to be inserted by name on the board name plate
of a frame.
2)
Hold the front panel with one hand and plug it into the board bottom along the
guide slot. The panel and the frame surface should be kept aligned. Then, press
inward the upper and lower front panels.
3)
Turn clock-wise the fastening screws on the panel until they are tightened.
4)
After the replacement, turn on the power (in case of a blocked BTRM, unblock it)
and view the indicator of a corresponding board to judge whether the board is
running normally.

1.1.5 Replacement Completed

After the replacement, the following three factors can help us judge whether it is
successful:
1)
View whether related indicator status is normal. For details, refer to the
sub-module "Board Indicator and DIP Switch" of the "Base Station Maintenance"
module in this manual.
2)
View a local-end maintenance console or OMC far end maintenance console to
see whether corresponding base station alarms have disappeared and any
recovery alarm has occurred.
3)
Conduct a dialing test with a mobile station to judge whether the base station
works normally.

1.2 General Backplane Replacement Process

1.2.1 Preparation

1)
Security precautions
Power supply board supports hot plugging. However, please follow every instruction
when replacing a power supply board. Prevent the board from being damaged by
static electricity. A backplane must be replaced with the power off and strictly based
on the operation procedures. Put on wrist strap and gloves and connect reliably the
grounding ends of them with the ground (the switch housing).
2)
Power off
Power off the whole BTS cabinet before the replacement.
3)
Commonly-used Tools
Before the replacement of a backplane, a cross screwdriver must be prepared to
match the M3 screw.
