Prepare to Replace an FESA

FESAs can be installed in slots 53 and 54 of a processor enclosure and in slots 51, 52,

53, and 54 of an I/O enclosure. See Figure 3-2 on page 3-19. When no FESA is

installed in a slot, a ServerNet adapter filler panel occupies the empty slot. (Therefore,

a ServerNet adapter filler panel can possibly occupy slots 53 and 54 of a processor

enclosure or slots 51 through 54 of an I/O enclosure.) The filler panel maintains proper

air flow and reduces electromagnetic interference (EMI).

Table 3-1 summarizes the steps for preparing to replace an FESA.
