2. Observe the RUN indicator on the DTMU board in the public subrack. The RUN indicator should
be slowly blinking (lighted 1s and off 1s) if the DTMU is normal.
Power-on
check of the
DTRU
1. Turn on the DC air-break switch of the DTRU subrack.
2. Check the RUN indicator on the DTRU plane. The RUN indicator should be slowly blinking
(lighted 1s and off 1s) if the DTRU board is normal.
Power-on
check of the
DDPU
1. Check the cable from the DDPU to the DTRU. Check whether the DDPU power cables are
correctly installed.
2. Turn on the DC air-break switch of the DDPU subrack.

Before installing the antenna system, mark all cables to avoid reverse connection of jumpers
and feeder cables. You can stick either labels or colored rings to cables to avoid reverse
connection of cables. Choose a method according to the customer demand.
Stick labels
You can stick corresponding labels to both ends of a cable to avoid reverse connection. The following
table shows the labels that are stuck to three directional dual-polarization cables configured for all
sectors in S6/6/6.
