FRU Identification, IOAM Enclosures
FRU Identification, IOAM Enclosures
Field-replaceable units (FRUs) are hardware components that can be serviced only by
service providers trained by HP. All components in an IOAM enclosure are FRUs.
FRUs are identified by their physical location in an enclosure by their group, module,
and slot numbers.
Group
A group consists of all components in an IOAM enclosure and derives its number from
the processor enclosure to which it is cabled.
Module
A module consists of a set of components that shares a backplane. In IOAM
enclosures, module 2 consists of power supplies, adapter slots, and fans in the left half
of the enclosure, and module 3 is on the right half, as viewed from the rear of the
cabinet. In addition, the ServerNet switch board is located in module 2 and sits on top
of the other switch board in module 3.
Slot
A slot is a physical, labeled space in a module in which a FRU can be installed.
IOAM FRU Identification
FRU locations in an IOAM enclosure are identified by group, module, and slot:
ServerNet Switch Identification
The module number of the ServerNet switch boards are displayed on the LCD in the
ServerNet switch board. Also, the module and slot numbers are displayed near the
slot.-; for example 2.1 for module 2, slot 1.
Identifier Use Label on the Front Label on the Rear
Group
number
Identifies the group associated
with its system enclosure. The
group number will be the same
as if it were an I/O enclosure.
None. Identify the
group number from
the rear.
Displayed on the
LCD in the
ServerNet switch
board.
Module
number
Identifies the module within the
group. The module number is
either 02 or 03.
None. Determined
by its position.
None. Determined
by its position.
Slot number Identifies the slot within the
module.
Near the slot. Near the slot.
