Verify the Switch Status

You can use the following commands on the management controller to check the status of the switch.

1. Identify the prerequisite and subsequent installation tasks that you must perform in conjunction with this procedure.

   See Installation Sequence.

2. Check the overall health of the switch:

   # showunhealthy 
   OK - No unhealthy sensors
   # 

   An unfavorable output from the showunhealthy command means a hardware fault with that particular component.

3. Check the status of the power supplies:

   # checkpower
   PSU 0 present status: OK
   PSU 1 present status: OK
   #

   A power supply output that is not OK from the checkpower command means that there is a problem with that power supply. See Check Power Supply Status LEDs for assistance.

4. Check the status of the fans:

   # getfanspeed
   Fan 0 rpm 12311
   Fan 1 rpm 12311
   Fan 2 rpm 12311
   Fan 3 rpm 12433
   Fan 4 rpm 12433
   #

   • A stopped or low speed in the output of the getfanspeed command means there is a problem with that particular fan.

   • If not present is in the output of the getfanspeed command, yet a fan is installed at the particular slot, there is a problem with that particular fan.

   For either condition, check the fan. See Servicing the Fans.

5. Check the status of the switch chips:

   # checkboot
   I4-A OK
   I4-B OK
   I4-C OK
   I4-D OK
   I4-E OK
   I4-F OK
   #

   If the output of the checkboot command is not OK, there is a problem with the particular switch chip. Try resetting the switch chip. See Reset the Switch Chip.

6. Alternatively, you can use the env_test command to perform the preceding checks and more:

   # env_test
   NM2 Environment test started:
   Starting Voltage test:
   Voltage ECB OK
   Measured 3.3V Main = 3.28 V
   Measured 3.3V Standby = 3.40 V
   Measured 12V = 12.06 V
   Measured 5V = 5.10 V
   Measured VBAT = 3.17 V
   Measured 1.8V = 1.78 V
   Measured 1.2V Standby = 1.21 V
   Measured 1.8V Standby = 1.80 V
   Measured 2.5VA = 2.51 V
   Measured 2.5VB = 2.51 V
   Measured 1.2VA = 1.22 V
   Measured 1.2VB = 1.22 V
   Measured 1.2VC = 1.21 V
   Measured 1.2VD = 1.21 V
   Measured 1.2VB = 1.21 V
   Measured 1.2VE = 1.21 V
   Measured 1.2VF = 1.21 V
   Voltage test returned OK
   Starting PSU test:
   PSU 0 present
   PSU 1 present
   PSU test returned OK
   Starting Temperature test:
   Back temperature 23.00
   Front temperature 32.62
   ComEx temperature 26.12
   I4-A temperature 55, maxtemperature 56
   I4-B temperature 48, maxtemperature 49
   I4-C temperature 53, maxtemperature 53
   I4-D temperature 48, maxtemperature 49
   I4-E temperature 53, maxtemperature 54
   I4-F temperature 53, maxtemperature 54
   Temperature test returned OK
   Starting FAN test:
   Fan 0 running at rpm 12433
   Fan 1 running at rpm 12311
   Fan 2 running at rpm 12311
   Fan 3 running at rpm 12433
   Fan 4 running at rpm 12433
   FAN test returned OK
   Starting Connector test:
   Connector test returned OK
   Starting I4 test:
   I4-A OK
   I4-B OK
   I4-C OK
   I4-D OK
   I4-E OK
   I4-F OK
   All I4s OK
   I4 test returned OK
   NM2 Environment test PASSED
   #

7. Once the switch has an operational status, start the Subnet Manager.

   See Start the Subnet Manager.
