Clearing Alarms
You can use the clear facility-alarm EXEC command to reset the external alarm relays and stop an
auditory alarm indication. However, the alarm cause and LED indication may still be in effect, and the
alarm can be viewed with the show facility-alarm status EXEC command until the alarm is cleared at
the source. To clear the source of an alarm, you must specify the source as either the secondary CPU,
one of the power entry modules (PEMs), or any device installed in the specified slot or subslot.
Clearing the source of an alarm is useful for:
• Removing a card from the chassis permanently or for an extended period of time
• Replacing a card with a different type of card in the same slot or subslot
The Cisco 6400 remembers the type of card originally installed in each slot or subslot, and removing a
card activates an alarm.
To clear the specified alarm, reset the alarm contacts, and remove the source of the alarm, use the
following EXEC command:
Note If all interfaces on an NLC or NRP are shut down prior to card removal (using the shutdown interface
command), the Cisco 6400 will not generate an alarm.
Example—Clearing All Alarms
The following example shows how to clear all current external alarm relays:
Switch# clear facility-alarm
Example—Clearing a Specified Alarm Source
Suppose you have an NRP-1 in slot 2. Removing the NRP-1 and inserting an OC-12 NLC will generate
an alarm. The following example shows how to clear the alarm:
Switch# clear facility-alarm source cardtype 2
Verifying Cleared Alarms
To verify that you cleared the alarms, use the show facility-alarm status EXEC command.
Command Purpose
Switch# clear facility-alarm [minor | major | critical]
[source {sec-cpu | pem {0 | 1} | cardtype {slot | slot/subslot}}]
Clears all alarms of the specified level, or
clears the specified alarm source.
