Step 13
Inform the OMC operator to verify that all relevant alarms have cleared.
A2-1.6 Replacing power supply units
This section contains the procedures for replacing power supply units on the WAVEXpress/BTS. Refer to Figure A3-1
for an illustration of the replacement position.
A WAVEXpress/BTS can have either one or two power supply units installed in the chassis. If there are two power
supply units installed, generally one of these units is used as the primary power supply and the other a backup power
supply that can assume the power load if the first power supply fails. The failed power supply unit can thus be replaced
without powering off the WAVEXpress/BTS and calls will not be dropped. If there is only one power supply unit, a BTS
failure indication will be sent to the OMC and calls will dropped. In either case, the procedures for replacing power
supply units are identical whether there are one or two units installed on the WAVEXpress/BTS.
Step 1
Power off the failed power supply unit by switching the power switch to the OFF position.
Step 2
Unplug the power cord from the AC outlet.
Step 3
Ensure that anti-static precautions are taken.
Step 4
Using a Phillips screwdriver, unscrew the screw located at the top-right corner of the power supply
unit.
Step 5
Pull out the power supply unit.
Step 6
Place the new power supply unit into the appropriate slot in the chassis (refer to Figure A3-1) and slide
in the unit until it completely rests inside the slot. Push the unit firmly into place.
Step 7
Using a Phillips screwdriver, screw in the removed screw onto the power supply unit.
Step 8
Plug the power cord into the AC outlet.
Step 9
Power on the WAVEXpress/BTS by switching the power switch to the ON position.
Step 10
Monitor the bootup process, refer to the maintenance manual for procedures.
Step 11
Inform the OMC operator to verify that all relevant alarms have cleared.
NOTE
☛
In the case of a power supply unit failure in a WAVEXpress system that contains two
power supply units, the OMC currently will not display an alarm. Therefore both
power supply units would have to fail before the OMC displays an alarm and
replacement is necessary.
