j. Error Type 1025: this error is not service-affecting, and no action is required.
k. Error Type 1538: the circuit pack was taken out of service because of an excessive rate of
uplink messages. Use test tone-clock location long to reset the circuit pack and
put it back into service. If the command is not successful, replace the circuit pack using the
procedure described in Replacing the IPSI or Tone-Clock Circuit Pack
on page 2337. If the
alarmed circuit pack is the active Tone-Clock of a duplicated pair, first interchange
Tone-Clocks using set tone-clock location to avoid a service outage. If the error
occurs again within 15 minutes, follow normal escalation procedures.
l. Error Type 2049 or 2305: these errors indicate the loss of one or more clock signals from
the reported IPSI or Tone-Clock circuit pack, which was active at the time of the error. The
effect of any of these errors is described in the table for Error Type 1. Diagnosis of the
problem is the same for all four Error Types, with the exception noted below.
1. Examine the Hardware Error Log for errors reported against circuit packs in the same
port network, especially TDM-CLK, TONE-BD, and EXP-INTF. Follow the repair or
replacement procedures indicated for any such errors found.
2. If the error is not corrected by resolving errors found in step 1, the IPSI or Tone-Clock
circuit pack should be replaced. See Replacing the IPSI or Tone-Clock Circuit Pack
on
page 2337.
Note:
Note: Replacing the circuit pack and retesting it with test tone-clock is not
adequate to retire this alarm and return the IPSI or Tone-Clock circuit pack to full
service; the Clock Health Inquiry test (#46) will continue to fail. Because the
ability to generate clocks was considered lost, once any repairs have been made
it is necessary to execute set tone-clock location override, forcing the
circuit pack to become active. If the problem was not corrected, this action may
cause a disruption in service for active digital facilities users.
3. If error 2305 or 3848 persists, all clock signals from the indicated board were lost.
If the reported Tone-Clock circuit is in a port network with duplicated Tone-Clocks, the
problem may lie with the circuit pack responsible for selecting the active Tone-Clock
circuit (the t/c selector, the active EXP-INTF circuit pack).
The t/c selector circuit pack of interest is the one which was active at the time the error
was logged. This is the currently active t/c selector, unless there has been an EXP-INTF
link switch. In order to determine whether an interchange has occurred since the
TONE-BD error, examine the display initcauses log for EXP-LNK entries in the
hardware error log for expansion link interchanges.
If the t/c selector circuit pack was not replaced as part of the previous step, replace it
now. Follow procedures described in EXP-INTF (Expansion Interface Circuit Pack)
on
page 1176 for the Expansion Interface, or Reseating and replacing circuit packs
in
Maintenance Procedures (03-300192).
