Fan Failures; Reporting Functions - Cisco Catalyst 9800-80 Installation Manual

Power Up and Initial Configuration

Fan Failures

Four internal fans draw cooling air in through the front of the chassis and across internal components to
maintain an acceptable operating temperature. The fans are located at the rear of the chassis. The fans in the
Cisco Catalyst 9800-80 Wireless Controller are numbered from 0 to 5, right to left.
When the system power is on, all fans should be operational. However, the system continues to operate even
if a fan fails.
Use the show platform hardware slot chassis 1 P2 fan status command to view the status of the fans, for
example:
WLC# show platform hardware slot chassis 1 P2 fan status
Fan group 1 speed: 60%
Fan 0: Normal
Fan 1: Normal
Fan 2: Normal
Fan 3: Normal

Reporting Functions

The chassis manager on the forwarding engine control processor manages the local resources of the forwarding
processor. The Cisco Catalyst 9800-80 Wireless Controller displays warning messages on the console, if the
chassis interface-monitored parameters exceed a threshold. You can also retrieve and display environmental
status reports with the following commands:
• show environment all
• show version
• show inventory
• show platform
• show platform software status control-processor
• show diag
Parameters are measured and reporting functions are updated every 60 seconds. A brief description of each
of these commands follows.
show environment all Command
The show environment all command displays temperature, voltage, fan, and power supply information.
The following is sample output from the show environment all command:
