Maintenance procedure
2
Post-reset check
Check to see that the following conditions are met before leaving the customer
premises:
1. The EI circuit pack in the SRP should be fast flashing.
This is appropriate
for Normal mode
, because the links are connected from the SREPN to the
Release 9r.
Figure 2-16
shows the SREPN EI board test results.
Figure 2-16.
Test fiber-link screen (SRP)
These Fail and Abort results are appropriate for Normal mode.
2. After normal service is returned to the SREPN, the SRP is in an
alarmed
state
. This is
normal
for the SRP and indicates that the TN2301 has
disconnected from the SREPN, and the SRP is no longer in control.
Connections are re-established between the EI in the SREPN and its EI/
SNI counterpart in the Release 9r PPN, and the system is now in its
original Release 9r-EI configuration.
Power alarms
Carrier power failure
A carrier power failure generates a MAJOR alarm against the CARR-POW
Maintenance Object. This condition is evident by:
■
A CARR-POW alarm in the Alarm or Error logs on the R9si system (SRP).
■
The LEDs in the SRP cabinet are all dark except for the yellow LED on the
TN2301 circuit pack.
