Locate a Faulty I/O Module

You must determine which I/O module is faulty before you replace it.

1. Consider your first step.
   • If you are at the switch, go to Step 2.
   • If you are remote to the switch, go to Step 4.
2. Check to see if the Attention LED is on.

   Each I/O module has an amber Attention LED on its front panel. Refer to the I/O module documentation (http://www.oracle.com/goto/f2-io-mod/docs) for more information about the I/O module LEDs.

3. Visually inspect the Link LEDs to see if any are any issues with the I/O module ports.

   Refer to the I/O module documentation (http://www.oracle.com/goto/f2-io-mod/docs) for more information about the I/O module LEDs.

   • If an I/O module is faulty, replace it.

     Start at Disconnect the I/O Module From the Switch Fabric.

   • If you cannot determine if an I/O module is faulty, go to Step 4.
4. Access the Oracle ILOM CLI.

   See Accessing the SP.

5. Issue show /System/Open_Problems to determine if an I/O module has become problematic.

   If the output contains the strings, MODULE or /SYS/MODULES/MODULEx where x is a number from 0 to 11, then that I/O module is faulty. Start at Disconnect the I/O Module From the Switch Fabric.

6. (Optional) Locate the module.

   → show /System/Networking/Modules/Module_5/ location
   
     /System/Networking/Modules/Module_5
       Properties:
           location = MODULE5 (Network Module 5)

7. Display the health status of the I/O modules.

   -> show /System/Networking/MODULES/ -t health
   Target             | Property              | Value
   -------------------+-----------------------+-----------------------------------
   /System/           | health                | OK
    Networking/       |                       |
    Modules/Module_0  |                       |
   /System/           | health                | OK
    Networking/       |                       |
    Modules/Module_1  |                       |
   /System/           | health                | OK
    Networking/       |                       |
    Modules/Module_3  |                       |
   /System/           | health                | OK
    Networking/       |                       |
    Modules/Module_5  |                       |
   /System/           | health                | Service Required
    Networking/       |                       |
    Modules/Module_6  |                       |
   /System/           | health                | OK
    Networking/       |                       |
    Modules/          |                       |
    Module_10         |                       |
   ->

   If any I/O module's health has a value other than OK, replace that I/O module. Start at Disconnect the I/O Module From the Switch Fabric.

8. Display the fault state of the I/O modules.

   -> show /SYS -t fault_state
   Target             | Property              | Value
   -------------------+-----------------------+-----------------------------------
   /SYS               | fault_state           | OK
   .
   .
   .
   /SYS/MODULES/      | fault_state           | OK
    MODULE0           |                       |
   /SYS/MODULES/      | fault_state           | OK
    MODULE1           |                       |
   /SYS/MODULES/      | fault_state           | OK
    MODULE3           |                       |
   /SYS/MODULES/      | fault_state           | OK
    MODULE5           |                       |
   /SYS/MODULES/      | fault_state           | Faulted
    MODULE6           |                       |
   /SYS/MODULES/      | fault_state           | OK
    MODULE10          |                       |
   .
   .
   .
   ->

   In the output, look for the rows beginning with /SYS/MODULES.

9. After identifying a faulty module, do either of the following:
   • If a module's fault state has a value other than OK, replace that I/O module.

     Start at Disconnect the I/O Module From the Switch Fabric.

   • If you are unable to determine if an I/O module is faulty, seek further information.
