The power supply circuitry for the equipment can constitute an energy hazard. Before you install or
replace the equipment, remove all jewelry (including rings, necklaces, and watches). Metal objects can
come into contact with exposed power supply wiring or circuitry inside the DSLAM equipment. This
could cause the metal objects to heat up and cause serious burns or weld the metal object to the
equipment.

DETAILED STEPS
Step 1
If a single card has reported the alarm, take the following actions depending on the reporting card:
• If the reporting card is an active traffic line port in a 1+1 protection group or part of a UPSR configuration, ensure
that an APS traffic switch has occurred to move traffic to the protect port.
Removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this,
perform an external switch if a switch has not already occurred. See the
Initiation, and Clearing, on page 443
section for commonly used traffic-switching procedures.
Note
• If the alarm is reported against an OC-N/STM-N card, complete the
Reset a Card in CTC, on page 449
procedure.
Step 2
If the alarm does not clear, complete the
Remove and Reinsert (Reseat) Any Card , on page 452
procedure.
Step 3
If the alarm does not clear, complete the
Physically Replace a Card, on page 453
procedure for the reporting card.
Step 4
If the single card replacement does not clear the alarm, or if multiple cards report the alarm, verify the office power. Refer
to the Install the Shelf and Common Control Cards chapter in the Configuration guide for procedures. See the
section as necessary.
Step 5
If the alarm does not clear, reseat the power cable connection to the connector.
Step 6
If the alarm does not clear, physically replace the power cable connection to the connector.
