3 Replacing an E4SA
This section describes how to perform online replacement of an Ethernet 4 ServerNet
adapter (E4SA) in an HP NonStop S-series server. An E4SA can be replaced without
shutting down the system. You might need to replace an E4SA if it has failed or
partially failed. If POST fails and if there is an alarm generated by the TSM package on
the SAC E4SA, the E4SA must be replaced.
This section includes the following topics:
You can run Parallel Library TCP/IP and NonStop TCP/IPv6 with the Ethernet failover
feature and replace the E4SA without taking down the TCP/IP communications. For
this to work on the E4SA, however, you must configure one of the failover pairs on a
LIF belonging to another adapter.
With Ethernet failover:
•
TCP sessions continue to operate if there are cabling or adapter failures
•
Network traffic automatically migrates from the faulty LIF to the working LIF
•
A single IP address can be shared between both LIFs (referred to as shared IP), or
each LIF can be configured to have its own IP address (referred to as non-shared
IP).
For more information about Ethernet failover, refer to the following manuals:
•
TCP/IP (Parallel Library) Configuration and Management Manual
•
TCP/IP (Parallel Library) Migration Guide
•
TCP/IPv6 Configuration and Management Manual
Note. As of G06.22 and later RVUs, the HP NonStop Open System Management (OSM)
Interface replaces TSM as the system management tool of choice for NonStop systems. For
instructions on using OSM or migrating to OSM, refer to the OSM documentation for your RVU.
Caution. If a previously installed E4SA and backplane connector have damaged pins, remove
the E4SA 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 E4SA to a different, undamaged slot. Both the E4SA and
backplane (or enclosure) must be replaced. For backplane replacement, refer to the backplane
replacement section of the HP NonStop S-Series Service Provider Supplement available in
G-series NonStop Technical Library (NTL).

Note. Whenever you handle an E4SA, you should follow standard operating practices to avoid
damage to the equipment. See Review Standard Operating Practices on page 3-21.
