PWRSUSP - OT or SVAC (Power management suspended)
This alarm is raised when the measured loss from the OT or SVAC input port to the
egress LD is greater than the theoretical loss by 4dB or more. The theoretical loss is
calculated using a combination of port insertion losses stored in the card SEEPs, nominal
connector/patch-cord losses, and also nominal losses calculated during commissioning.
The alarm will be raised when the power control loop for the OT or SVAC attempts to
change its power (to get the egress LD channel power to the correct value) and reaches
the 4dB clamp.
The cause of this condition may be one or more of the following:
• damaged fiber
• dirty fiber
• dirty port (OT, SVAC, or CWR8 port (A, B, C, or D))
Corrective Action
A cold reset, reseat, or replacement of a card is service impacting if the card is currently
carrying services. To determine if any services are currently carried over a card, perform
the procedure
If there are services currently carried over the card, it may be best to wait for a
maintenance window before resetting, replacing, or reseating the card.
At the end of each step wait to see if the fault clears. If not, continue with the next step.
...................................................................................................................................................................................................
1 Trace the fiber connecting the alarmed OT or SVAC Line port through the packs
preceding the CWR8 pack or directly to the CWR8 OMD In, or CWR8 CLS (1 to 8) port.
If there is no CWR8 pack for this line trace the fiber connecting the alarmed OT or SVAC
Line port through the packs preceding the LD pack Line Out port.
...................................................................................................................................................................................................
2 Clean the fiber ends connecting the alarmed OT or SVAC Line port to the next pack
preceding the CWR8 pack. Packs that may be included in the path to the CWR8 include
the OMD44.
...................................................................................................................................................................................................
3 If the preceding steps did not clear the alarm clean the CWR8 OMD port or CLS (1 to 8)
port that the channel passes through. If there is no CWR8 pack for this line clean the fiber
connections between the packs up to the egress line at the LD pack Line Out port.
