Locating System Components in an Enclosure

Figure 2-4 shows an example of a NonStop S-series I/O enclosure. IOMF 2 CRUs look

slightly different from the IOMF CRUs shown installed in slots 50 and 55 in the figure.

Also, if IOMF 2 CRUs are present, power supplies are installed at the bottom of the

enclosure in slots 31 and 32, below the fans. See Figure 2-3 on page 2-8.

Figure 2-5 shows an example of NonStop IOAM enclosures in a system rack. Note that

each IOAM enclosure contains two I/O adapter modules (IOAMs), two ServerNet

switch boards, and slots for up to 10 Fibre Channel ServerNet adapters (FCSAs) or 10

Gigabit Ethernet 4-port ServerNet adapters (G4SAs).

The form factor of this type of enclosure differs radically from that of the processor and

I/O enclosures. IOAM enclosures contain no CRUs. None of the components are

replaceable by customers and are therefore FRUs.
