Replacement Procedures
This subsection includes the following replacement procedures:
To service or replace all other server components, refer to the NonStop S-Series
Hardware Support Guide or the CSSI Web site. (Click Start>Programs>Compaq
TSM>Compaq S-Series Service (CSSI) Web.
Do not attempt to replace a component unless you have exhausted all other
troubleshooting techniques and are reasonably certain that replacement is the only
alternative.
Replacing an MSEB
You use the guided replacement procedure to replace an MSEB. From the system
console of the server you are adding, choose Start>Programs>Compaq
TSM>Guided Replacement Tools>Replace SEB or MSEB. Online help is available
to assist you in performing the procedure. You can replace only one MSEB at a time.
Replacing a PIC in a ServerNet II Switch
PICs installed in a ServerNet II Switch cannot be replaced in the field. If a PIC is
determined to be faulty, the ServerNet cable attached to the PIC must be moved to an
unused port on the switch. (Remember that both fabrics must connect to the same
switch port number. If you move a ServerNet cable to a different port on the switch, you
must move the corresponding cable for the alternate fabric.) If no unused port is
available, the switch and its power subsystem must be replaced.
To move a ServerNet cable to a different port on a ServerNet II Switch, refer to
Section 6, Adding or Removing a Node.
