5. Power down the standby processor carrier by:
a. Remove the power plug from the
left side
of the carrier first.
b. Remove the second power plug from the
right side
of the carrier.
6. Remove the failed circuit pack and replace it with a new one of the same
type.
7. Power up the standby processor carrier by:
a. Insert the power plug in the right side of the carrier first.
b. After inserting the first power plug in the right insert the second
power plug in the left side of the carrier.
The red and green LEDs will light indicating restoration of power and
testing of the boards. These LEDs will go out as tests pass.
8. This step is optional. Use a terminal and the SPE-down interface to test the
standby SPE as follows.
If a terminal is connected to the STANDBY connector on the back of either
PPN control carrier, the power-up reboot of the standby aborts and the
SPE-Down interface can then be used to enter commands to the LMM
firmware. Use
t al
, or the SPE-Down interface test command for the
replaced component, to confirm that the problem is fixed. Repair any
failures reported.
When testing is finished, move the SPE-Select switches to the AUTO
position
one at a time
. This unlocks the standby and begin a reboot which
can be monitored from the terminal.
9. Verify that the standby is up.
Regular flashing of the yellow LED on the Processor board indicates that
the standby SPE is up and cycling. If the yellow LED is not flashing after
five minutes, test the standby SPE as described in the above step. Relock
the SPE standby, attach a terminal to the STANDBY connector on the back
of either PPN control carrier and execute the SPE-down interface tests. All
tests must pass before unlocking.
10. If the standby SPE is still locked, unlock it by returning both SPE-Select
switches to the AUTO position
one at a time
.
11. Enter status spe to confirm that handshake is up. This should occur within
2 minutes. When it is, enter the test long clear command for the replaced
component. If an alarm does not clear, consult the appropriate MO.
12. Verify that the standby SPE is brought into service.
Enter status spe. The standby SPE is fully operational when handshake is
up, shadowing is on, and memory is refreshed. It can take up to 10
minutes after unlocking for the standby to be brought fully into service.
13. If the standby SPE does not fully return to service, consult ‘‘STBY-SPE
(Standby SPE Maintenance)’’.
