Connect Router to the Network
Command Description
show media Displays the current state of the disk storage media.
show inventory Displays information about the field replaceable units (FRUs), including product IDs, serial numbers,
and version IDs.
show environment power Displays the power usage information for the entire router.
show environment fan Displays the status of the fan trays.
show environment Displays temperature readings for card temperature sensors. Each module has temperature sensors with
temperature two thresholds:
Note
show environment Displays the voltage for the entire router.
voltage
• Minor temperature threshold – When a minor threshold is exceeded, 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 on board 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 exceeds 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.
• For some card temperature sensors, the temperature thresholds for both minor and
major might display 'NA'. This is an expected behaviour and indicates that there are
no alarms for those corresponding thresholds.
