The SWAP procedure
Content
Preparation work before SWAP-install and Debug ZTE power
Debug the power:Check whether the can work normallySet the parameters Check whether the generator can start when the battery charge current is 0.1C
Preparation work before SWAP-connect RBS cable
24V +
GND
Make terminals and labels in RBS side
-48V
Preparation work before SWAP-connect IDU cable
GND
Make terminal in IDU side Make sure the -48V and GND are right
SWAP procedure-SWAP RBS power cable
After start the generator , please call MTN staff about the SWAP
SWAP procedure-SWAP RBS power cable
24V battery +
24V battery -Take the battery + and battery – cable from RBS. And it must be covered with insulation tap
Do not touch the breaker here
SWAP procedure-SWAP RBS power cable
Install new 24v power cable from ZTE powerMake sure the Positive and negative poles are right
SWAP procedure-SWAP RBS power cable
AC input of 24v power module
1.Switch on the breaker of the new power cable and check the power voltage (27V)
2.Take off the A C input socket of 24V power module and check if the RF module can work
If every thing is ok, take off power alarm cable
SWAP procedure-SWAP IDU power cable
Switch on the breaker of new IDU power cable, and check the power voltage
Take AC input power cable of IDU Insert the new DC power for IDU If the IDU can not work, rollback
After SWAP , call MTN engineer to check if every is OK
Tidy UP the side
1.Tidy the cable and make label2.Clean up the site3.If there is commercial power , turn off the generator
