Maintaining M320 FPCs
Purpose
For optimum router performance, verify the condition of the FPCs. The router can have up to eight FPCs mounted vertically in the FPC card cage at the front of the chassis.
Action
On a regular basis:
Check the LED display on the craft interface and the LEDs on the craft interface directly above each FPC slot. The green LED labeled STATUS lights steadily when an FPC is functioning normally.
During normal operation:
The green STATUS LED above the FPC on the craft interface lights steadily when the FPC is online and functioning normally.
The green STATUS LED blinks during startup.
Issue the CLI show chassis fpc command to check the status of installed FPCs. As shown in the sample output, the value Online in the column labeled State indicates that the FPC is functioning normally:
user@host> show chassis fpcTemp CPU Utilization (%) Memory Utilization (%) Slot State (C) Total Interrupt DRAM (MB) Heap Buffer 0 Online 37 2 0 256 9 41 1 Empty 2 Online 37 3 0 256 8 41 3 Empty 4 Empty 5 Empty 6 Empty 7 Empty
For more detailed output, add the detail option. The following example also specifies a slot number (0), which is optional:
user@host> show chassis fpc detail 0Slot 0 information: State Online Temperature 37 degrees C / 98 degrees F Total CPU DRAM 256 MB Total SRAM 28 MB Total SDRAM 256 MB Start time: 2003-10-01 04:19:30 PDT Uptime: 10 days, 7 hours, 16 minutes, 48 seconds
