AC Power for DC-Powered Systems
NOTE:
For environment maintenance, the PPN or EPN cabinet configuration
aspects in a High or Critical Reliability system are irrelevant.
1. Where P is an appropriate port network number determined via the PORT field from the
Alarm or Error Log.

FAIL
(cont’d.)
2. Procedures for a Global MCC (J58890CH):
a. For a nominal holdover system if there is no AC power at the wall
outlet, then the problem is not with the system itself. Power must be
restored to the wall outlet.
b. If there is AC power at the wall outlet, then there could be a
problem with the Rectifiers (RM850), Battery Interface Unit, or
battery. Resolve all alarms logged against the POWER
Maintenance Object, and rerun the test. If the test still fails, the BIU
may be defective. Check to see if the BOD alarm LED is “on”, on
the BIU. If the BOD LED is “on” replace the Battery Interface Unit
(BIU). If the BOD LED is “off” and the BOK LED is “on” then the
SYSAM or the EPN Maintenance circuit pack may be incorrectly
reporting the problem. Resolve all alarms against these
Maintenance Objects and rerun the test.
100 FAIL The switch is currently without AC power, and AC Power maintenance is in
the middle of timing the NPH interval.
1. Follow the repair steps outlined above for Error Code 1.
PASS The PR-MAINT (Maintenance/Tape Processor) in a PPN in a system
without High or Critical Reliability, the DUPINT (Duplication Interface)
circuit pack in a High or Critical Reliability system PPN, or the EPN MAINT
(Maintenance) circuit pack in an EPN multicarrier cabinet system has
reported that the switch has AC power. If there is no AC power at the wall
outlet, then look for and resolve all alarms against the appropriate MO
listed.
