Maintaining the Fan Tray

The fan trays install into the rear of the chassis, as shown in Figure 2. To check the status of the fans in the fan trays, issue the show chassis environment command. The output includes an entry for each fan, as shown in this example:

user@host>	show chassis environment
Class Item		Status	Measurement
...
Fans Left	Fan 1	OK	Spinning at normal speed
Left	Fan 2	OK	Spinning at normal speed
Left	Fan 3	OK	Spinning at normal speed
Left	Fan 4	OK	Spinning at normal speed
Left	Fan 5	OK	Spinning at normal speed
Left	Fan 6	OK	Spinning at normal speed
Left	Fan 7	OK	Spinning at normal speed
Left	Fan 8	OK	Spinning at normal speed
...

Maintaining PICs and PIC Cables

To maintain PICs and PIC cables, follow these guidelines:

■Check the LEDs on PIC faceplates. Most PIC faceplates have an LED labeled STATUS. Some PICs have additional LEDs, often one per port. The meaning of the LED states differs for various PICs. For more information, see the M10i Internet Router PIC Guide. If the FPC that houses the PIC detects a PIC failure, the FPC generates an alarm message to be sent to the Routing Engine.

■Issue the CLI show chassis fpc pic-statuscommand. The PIC slots in an FPC are numbered from 0 through 3, right to left:
