Maintaining T640 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 LCD on the craft interface and the LEDs on the craft interface directly above
each FPC slot. During normal operation:
• The OK LED lights steadily.
During normal operation, the green OK LED above the FPC on the craft interface
lights steadily when the FPC is online and functioning normally. The green OK 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 fpc
Temp CPU Utilization (%) Memory Utilization (%)
Slot State (C) Total Interrupt DRAM (MB) Heap Buffer
0 Online 23 2 0 256 12 49
1 Online 26 5 0 256 21 49
2 Online 31 5 0 1024 6 49
3 Online 31 8 0 1024 6 49
4 Online 26 26 0 1024 4 49
5 Online 25 2 0 256 12 49
6 Online 23 1 0 256 12 49
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 0
Slot 0 information:
State Online
Temperature 23 degrees C / 73 degrees F
Total CPU DRAM 256 MB
Total SRAM 36 MB
Total SDRAM 640 MB
Start time 2008-12-12 11:02:43 PST
Uptime 5 hours, 18 minutes, 51 seconds
