Both the controller and IOXM FRUs have a number of internal FRUs for which there are corresponding fault LEDs. In addition, there is a summary FRU fault LED on the external face-plate of both the controller and IOXM; labeled with a "!". A summary fault LED will be on when any of the internal FRU fault LEDs are on.

All FRU fault LEDs are amber in color. However, not all amber LEDs in the system are FRU fault LEDs. Externally visible fault LEDs are labeled with a "!" and internal FRU fault LEDs remain on, even when the controller or IOXM is removed from the chassis.

FRUs are identified by a FRU ID and slot tuple. FRU IDs include: DIMMs, cards in PCI slots, boot media devices, NV batteries and coin cell batteries. For each FRU ID, the FRUs are numbered 1 through N, where N is the number of FRUs of that particular type that exist in the controller or IOXM. Both controller and IOXM have a FRU map label for use in physically locating internal FRUs. The FRU ID/slot tuple used by the system controller fru led show command matches that specified on the FRU map label.

Parameters

{ [-fields <fieldname>,…]: If you specify the -fields <fieldname>, … parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.
| [-instance ] }: If you specify the -instance parameter, the command displays detailed information about all fields.
[-node {<nodename>|local}] - Node: Selects FRU fault LEDs on the specified nodes.
[-fru-id <FRU LED key>] - FRU ID: Selects the FRU fault LEDs that match the specified FRU type.
[-fru-slot <integer>] - FRU Slot: Selects the FRU fault LEDs that match the specified slot.
[-fru-bay <text>] - FRU Bay: Selects the FRU fault LEDs that match the specified bay.
[-fru-state {on|off|unknown}] - FRU State: Selects the FRU fault LEDs that match the specified status.
[-lit-by <text>] - Lit By: Selects the FRU fault LEDs that were lit by the specified source.
