Prepare to Replace a TRSA

TRSAs 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 3-14. When no TRSA is installed

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

ServerNet adapter filler panel might 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).
