Prepare to Relocate an E4SA

E4SAs 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 4-3 on page 4-21. When no E4SA 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 4-1 summarizes the steps for preparing to relocate an E4SA.

Note. E4SAs (including E4SA connections via S-series I/O enclosures) are not supported on

NonStop BladeSystems.

Note. You can configure the Parallel Library TCP/IP and NonStop TCP/IPv6 subsystems with

the Ethernet failover feature, which provides fault-tolerance at the adapter level. If you want to

be able to later replace the E4SA without halting TCP/IP communications, configure the

Ethernet failover pair on LIFs belonging to different adapters.
