Displays temperature readings for card temperature sensors. Each system controller, route processor, line
card, and fabric card has temperature sensors with two thresholds:
• Minor temperature threshold – When a minor threshold is exceeded, a minor alarm occurs and the
following actions occur for all four sensors:
• Displays system messages
• Sends SNMP notifications (if configured)
• Log environmental alarm event that can be reviewed by running the show alarm command.
• Major temperature threshold – When a major threshold is exceeded, a major alarm occurs and the
following actions occur:
• For sensors 1, 3, and 4 (outlet and onboard sensors), the following actions occur:
• Displays system messages.
• Sends SNMP notifications (if configured).
• Logs environmental alarm event that can be reviewed by running the show alarm command.
• For sensor 2 (intake sensor), the following actions occur:
• If the threshold is exceeded in a switching card, only that card is shut down.
• If the threshold is exceeded in an active route processor card with HA-standby or standby
present, only that route processor card is shut down and the standby route processor card
takes over.
• If you do not have a standby route processor card in your router, you have up to 2 minutes
to decrease the temperature. During this interval, the software monitors the temperature
every 5 seconds and continuously sends system messages as configured.
Cisco recommends that you install dual route processor cards. If you are using a router without
dual route processor cards, Cisco recommends that you immediately replace the fan card if
just one fan is not working.
