8.
Measure DC power module faceplate DC voltages. Check DC power feed
(from customer premises) if voltage IN requirements are not met. If voltage
OUT requirements are not met, replace DC protector card, then replace DC
power module.
Requirement:48RTN to -48, 38 to 63 V DC (about 2 volts less than measured
at the DC feed terminal block). (36 to 63 if video is connected.)
24 to GND, 22 to 26 V DC.
9.
Open 900A2 or 900A3 DT encloser. Turn power switch ON and verify power
LED lights. Then turn power switch OFF and close DT. If power LED does not
light, verify DT power cord is connected to the DC power module, then replace
DT.
10. Repeat this procedure for next DT/customer power feed as required.
11. Replaces DC power interface cover. Close and secure DT pedestal (if not per-
forming turnup procedures at this time).
STOP. YOU HAVE COMPLETED THIS PROCEDURE.
