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
