3 Replacing an FESA
This section describes how to perform online replacement of a Fast Ethernet
ServerNet adapter (FESA) in an HP NonStop S-series server. You might need to
replace an FESA if it has failed or partially failed. If POST fails and if there is an alarm
generated by the TSM package on the SAC FESA, the FESA 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 FESA without taking down the TCP/IP communications.
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
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 FESA and backplane connector have damaged pins, remove
the FESA 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 FESA to a different, undamaged slot. Both the FESA 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 the
G-series NonStop Technical Library (NTL) collections.

Note. Whenever you handle an FESA, you should follow standard operating practices to avoid
damage to the equipment. See Review Standard Operating Practices on page 3-20.
