Monitoring the Craft Interface Status
Viewing the Craft Interface Status
Purpose
To determine a craft interface failure by checking the craft interface status.
Action
To view the craft interface status, look at the craft interface panel on the front of the router chassis.
When the craft interface fails, you might not see any lights on the craft interface panel and the LCD display will be blank. In addition, the buttons on the panel might not work as indicated.
You can view the craft interface information with the following command:
If the craft interface fails, you can still view current craft interface information at the command line. A craft interface failure or removal generates a red alarm.
Checking the Craft Interface Environmental Status
Purpose
To check the environmental status of the craft interface.
Action
To view the craft interface status, use the following command:
Sample Output
For M5, M10, M20, and M40 routers:
user@host> show chassis environment Class Item Status Measurement [...Output truncated...] Misc Craft Interface OK
For M40e and M160 routers:
user@host> show chassis environment
Class Item Status Measurement
[...Output truncated...]
FPM CMB OK 32 degrees C / 89 degrees F
FPM Display OK 32 degrees C / 89 degrees F
[...Output truncated...]
For M40e and M160 routers:
user@host> show chassis environment
Class Item Status Measurement
[...Output truncated...]
FPM GBUS OK 28 degrees C / 82 degrees F
FPM Display OK 31 degrees C / 87 degrees F
[...Output truncated...]
Meaning
For M5, M10, M20, and M40 routers, the command output displays the craft interface state, which can be OK or Absent.
For M40e and M160 routers, the command output displays the FPM Chassis Management Bus (CMB) status and the FPM display status, which can be OK or Absent.
For M320 routers, the command output displays the FPM CMB status only.
For T320 routers and T640 routers, the command output displays the FPM circuitry and the FPM display status, which can be OK or Absent.
(For M40e, M160, M320, and T320, T640, T1600, and TX Matrix routers) To monitor the craft interface environmental status, use the following command:
user@host> show chassis environment fpm FPM status:
State Online
FPM CMB Voltage:
5.0 V bias 5030 mV
8.0 V bias 8083 mV
FPM Display Voltage:
5.0 V bias 4998 mV
FPM CMB temperature 34 degrees C / 93 degrees F
FPM Display temperature 35 degrees C / 95 degrees F
CMB Revision 12
The command output displays the status of the FPM or craft interface, which can be Online or Offline. It also displays information about the power supplied to the FPM CMB or FPM GBUS, information about the FPM display power supply, the temperature of the air flowing past the FPM CMB or FPM GBUS and the FPM display, and the CMB or GBUS revision level.
