VERSION 0.1 2014-11-01 PAGE 4.1.35
Power Supply Module and LVPS Faults
There are various power supply module and LVPS module related alarms on the AUI (local or remote) or
controller UI.
Power supply module alarms are prefixed by the text
RF Module and then PS
. The number that
appears after
RF Module
(1-12) identifies the position of the affected module. The letter that appears
after
PS
(
A
or
B
) identifies the affected power supply module. There are two power supply modules for
each RF power module.
Low voltage power supply (LVPS) alarms are prefixed by the text
LVPS
. The number and letter that
appears after
LVPS
(
A
or
B, 2A or 2B
, if installed) identifies the affected LVPS module.
1. Check the front panel LEDs of the power supply modules and LVPS modules. Normally, only the AC
OK and DC OK LEDs should be on (solid green). If not, the associated power supply module or LVPS
module may be defective. Proceed to
“Power Supply or LVPS Module Fault Validation” on
page 4.1.38 .
2. From the AUI’s (local or remote)
Meter List View
page (see Figure 4.1.8 on page 4.1.36 ):
 select the
i
(information) button next to the RF Modules # folder in the Transmitter Layout
section to view the status screen for all modules or select the right-hand arrow to expand the
RF Modules folder to allow clicking on the
i
button for an individual RF Module (e.g., RF
Module 1, see Figure 4.1.9 on page 4.1.36 ). This screen displays critical parameters for the
power supply modules. As an aid in troubleshooting, compare parameters to isolate possible
faults.
 select the
i
(information) button next to the Rack # folder in the Transmitter Layout section
and then to view the Rack status screen (see Figure 4.1.10 on page 4.1.37 ). This screen
