e. If you have an alarm and all LEDs are ok (PWR OK and BOK) on the
rectifier modules, and the BIU (Battery Interface Unit), make sure the
BIU and the RM0850 rectifiers are seated properly (plugged in). If the
BOK LED on the BIU is ok use the following information to check the
number of rectifiers serving this cabinet:
Number of carriers Number of rectifiers
per cabinet per cabinet
----------------------------|---------------------------------
1 2
2 3
3 3
4 4
5 4
If the number of rectifiers is correct replace the maintenance circuit pack
in the EPN or PPN.
4. If the test still fails, then follow normal escalation procedures.
10 FAIL This indicates that Error Codes 2 and 8 have occurred. Refer to these
descriptions. Also, refer to the description for Error Code 14 for this test.
12 FAIL This indicates that Error Codes 4 and 8 have occurred. Refer to these
descriptions. Also, refer to the description for Error Code 14 for this test.
14 FAIL This indicates that Error Codes 2, 4, and 8 have occurred. Refer to these
descriptions.
NOTE:
This could also indicate that the detection logic on the DUPINT
(Duplication Interface), PR-MAINT (Maintenance/Tape Processor), or
EPN MAINT (Maintenance) circuit pack is defective. Such an error will
not be detected by the respective maintenance. If many environment
tests are failing, replace the suspect circuit pack (depending on system
configuration).
PASS The Maintenance/Tape Processor in a multicarrier cabinet PPN system without
High or Critical Reliability, the Duplication Interface circuit pack in a PPN for a
High or Critical Reliability system, or the EPN Maintenance circuit pack in an
EPN have reported that the status of Battery & Battery Charger is good.
