3 Replacing an ATM3SA Adapter
You might need to replace an ATM3SA adapter if it has failed or partially failed. This
procedure describes how to replace an ATM ServerNet adapter (ATM3SA) in a
NonStop S-series server that is online. You do not need to shut down the system
before replacing an ATM3SA adapter. The information in this procedure is valid for all
G06 RVUs.
Removal and replacement of the ATM3SA adapter is described in the following
subsections:

Prepare to Replace an ATM3SA Adapter
ATM3SA adapters 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 3-12. When no
ATM3SA is installed in a slot, a ServerNet adapter filler panel occupies the empty slot.
(Therefore, a ServerNet adapter filler panel can occupy slots 53 or 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 shows the part numbers for the ATM3SA and filler panel.
Table 3-2 summarizes the steps for preparing to replace an ATM3SA adapter:
Caution. If a previously installed ATM3SA adapter and backplane connector have damaged
pins, remove the ATM3SA adapter and install a filler panel in the vacant slot. Attach red tags to
the filler panel to identify the slot. Do not move the damaged ATM3SA adapter to a different,
undamaged slot. Both the ATM3SA adapter and backplane (or enclosure) must be replaced.
For backplane replacement, refer to the backplane replacement section of the NonStop
S-Series Service Provider Supplement available in G-series NonStop Technical Library (NTL)
Icollections.
Note. Whenever you handle an ATM ServerNet adapter (ATM3SA), follow standard operating
practices to avoid damage to the equipment. See Review Standard Operating Practices
on
page 3-14.
