Term Definition
System enclosure An enclosure for system components. Processor enclosures and I/O
enclosures are both system enclosures.
Processor
enclosure
A system enclosure that contains, among other units, two processor
multifunction (PMF) customer-replaceable units (CRUs).
I/O enclosure A system enclosure that contains, among other units, two I/O
multifunction (IOMF) CRUs. I/O enclosures connect to a SEB or
MSEB in the processor enclosure.
I/O enclosures can also be attached to a processor switch of an
Integrity NonStop NS-series system. For more information and for
cabling procedures, your service provider should refer to the NonStop
NS-Series Hardware Installation Manual.
I/O adapter module
(IOAM) enclosure
An enclosure that contains up to 10 specially designed ServerNet
adapters. Unlike self-contained system enclosures, IOAM enclosures
reside in standard 19-inch racks. IOAM enclosures connect to an
MSEB in the processor enclosure. I/O enclosures and IOAM
enclosures can coexist in the same system. For information about
what group numbers support IOAM enclosures, see Table 1-2
.
Caution. IOAM enclosures must be installed by service providers trained by HP.
Term Definition
Block A grouping of one or more system enclosures that a NonStop
S-series system recognizes and supports as one unit. A block can be:
One processor enclosure
One I/O enclosure
One processor enclosure attached to one or more I/O or IOAM
enclosures. Note that IOAM enclosures are not standalone
enclosures; they are mounted into standard 19-inch racks.
