To troubleshoot an SPC, follow these guidelines:
user@host> show chassis fpc Temp CPU Utilization (%) Memory Utilization (%) Slot State (C) Total Interrupt DRAM (MB) Heap Buffer 1 Empty 41 9 0 1024 15 57 2 Online 43 5 0 1024 16 57 3 Online 43 11 0 1024 16 57 4 Empty 5 Empty 6 Online 42 6 0 1024 16 57
For more detailed output, add the detail option. The following example does not specify a slot number, which is optional:
user@host> show chassis fpc detail
Slot 2 information: State Online Temperature 43 degrees C / 109 degrees F Total CPU DRAM 1024 MB Total RLDRAM 256 MB Total DDR DRAM 4096 MB Start time: 2007-07-10 12:28:38 PDT Uptime: 1 hour, 33 minutes, 47 seconds Slot 3 information: State Online Temperature 43 degrees C / 109 degrees F Total CPU DRAM 1024 MB Total RLDRAM 256 MB Total DDR DRAM 4096 MB Start time: 2007-07-10 12:28:40 PDT Uptime: 1 hour, 33 minutes, 45 seconds Slot 6 information: State Online Temperature 42 degrees C / 107 degrees F Total CPU DRAM 1024 MB Total RLDRAM 256 MB Total DDR DRAM 4096 MB Start time: 2007-07-10 12:28:42 PDT Uptime: 1 hour, 33 minutes, 43 seconds
