3 Replacing a GESA
This section describes how to perform online replacement of a Gigabit Ethernet
ServerNet adapter (GESA) in a NonStop S-series server. You might need to replace a
GESA if it has failed or partially failed. If POST fails and an OSM or TSM alarm is
generated on the GESA SAC, you must replace the GESA.
This section includes the following topics:
Note. A GESA can be replaced without shutting down the system.
Caution. If a previously installed GESA and backplane connector have damaged pins, remove
the GESA and install a filler panel (U09021) in the empty slot (see Figure 2-2
on page 2-5).
Attach red tags to the filler panel to identify the slot. Do not move the damaged GESA to a
different slot. Both the GESA and backplane (or enclosure) must be replaced. For backplane
replacement, refer to the backplane replacement section of the NonStop S-Series Service
Provider Supplement.
