module is a subset of a

group

and is usually contained in an enclosure. In NonStop

multifunction I/O board (MFIOB)

A ServerNet adapter that contains

ServerNet addressable controllers (SACs)

for

SCSI

and Ethernet; a

service processor

; a router with ServerNet links to the

processor

, to the

two ServerNet adapter slots, and to one of the

ServerNet expansion board (SEB)

slots;

and connections to the

serial maintenance bus (SMB)

, which connects components within

the

enclosure

to the service processor. The MFIOB is integrated into the

I/O

multifunction (IOMF) CRU

ServerNet cables. Two-lane links and four-lane links are examples of multilane links.

multimode fiber-optic (MMF) ServerNet cable

A fiber-optic cable that either allows more than one mode to propagate or supports
propagation of more than one mode of a given wavelength. MMF ServerNet cable
typically supports shorter transmission distances than

single-mode fiber-optic (SMF)

ServerNet cable
