USALS
USALS (Auto Laser Shutoff Due to Upstream Fault)
USALS is raised when the client port laser is turned off either because the network port of
this card has an optical LOS, or the corresponding client port at the far end of the service
has a fault.

NOTICE
Service-disruption hazard
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 “Reseating a Card” (p. 3-19).
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
Determine which network port on the near-end card is associated with the client port that
has raised the USALS condition. Network ports for this product are usually port 1. Look
for LOS, LOC or LOF at the network port or Out of Service type alarms at the associated
client port(s).
...................................................................................................................................................................................................
2
Using the applicable procedure for the fault detected in Step 1, clear the fault.
