Base Enclosure

A base enclosure is an enclosure that is mounted on a frame base with casters and is

installed directly on the floor. It can have another enclosure stacked on top of it.

Stackable Enclosure

A stackable enclosure is an enclosure that is installed on top of a base enclosure and

is not mounted on a frame base.

Processor Enclosure

A processor enclosure is a system enclosure that contains processor multifunction

(PMF) CRUs. A processor enclosure can also contain:

•

ServerNet expansion boards (SEBs or MSEBs) (optional)

•

ServerNet adapters (optional)

Processor enclosures cannot contain I/O multifunction (IOMF) CRUs.

I/O Enclosure

An I/O enclosure is a system enclosure that contains IOMF CRUs. An I/O enclosure

can also contain ServerNet adapters. I/O enclosures cannot contain PMF CRUs,

SEBs, or MSEBs.

Modified I/O Enclosure

A modified I/O enclosure is an I/O enclosure that has two pins cut off on one of the

backplane connectors in slot 50 or 55 to correct a design defect. A modified I/O

enclosure is identified by a revision label on the cable-management post.

A modified I/O enclosure can contain IOMF CRUs or IOMF 2 CRUs. A modified I/O

enclosure cannot be converted to a processor enclosure containing S7000, S7400,

S70000, or S72000 PMF CRUs, but it can be converted to a processor enclosure

containing S7600 and S74000 or later PMF CRUs.

For more information about this modification, contact your HP service representative.

IOAM Enclosure

An IOAM enclosure is an enclosure that contains up to 10 ServerNet adapters. Unlike

system enclosures that are self-contained, IOAM enclosures are mounted in 19-inch

racks. IOAM enclosures do not include the system enclosure frames. IOAM enclosures

and components require OSM; they are not supported by TSM.
