Replacing a PIC in an MSEB
Replacing a PIC in an MSEB
PICs installed in an MSEB can be replaced, but the MSEB must be removed from the
enclosure before the PIC can be replaced. To remove the MSEB safely, you must use
the guided procedure. 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.
Perform each step in the guided procedure up to and including removing the MSEB
from the enclosure. Then refer to the Replace SEB or MSEB Guided Procedure online
help for instructions on replacing the PIC. When the PIC is replaced, use the guided
procedure to reinstall the MSEB in the enclosure.
Replacing a Fiber-Optic Cable Between an MSEB and a
ServerNet II Switch
Use this procedure to replace a fiber-optic cable between an MSEB and a ServerNet II
Switch:
1. Before starting, make sure that the internal and external ServerNet fabrics served
by the cable opposite the one you are replacing are healthy. See Checking the
External ServerNet X and Y Fabrics on page 7-29. For example, if you are
replacing the cable for the X fabric, make sure that the internal Y fabric for all other
nodes and the external Y fabric are fully operational.
2. Review the information on connecting fiber-optic cables in Section 3, Installing and
Configuring a ServerNet Cluster.
3. Route the replacement cable between the MSEB and the ServerNet II Switch.
4. Disconnect the suspected bad cable from the MSEB and from the ServerNet II
Switch.
5. If the replacement cable has dust caps, remove the dust caps and install them on
the suspected bad cable.
6. Connect the replacement cable to the ServerNet II Switch and then to the MSEB.
Make sure that you connect the replacement cable to the ports from which you
removed the suspected bad cable.
7. Use the TSM Service Application to check for alarms, as described in Using TSM
Alarms on page 7-12.
8. After a while, most TSM alarms should clear automatically. If the alarms do not
clear, run the Node Connectivity ServerNet Path Test. See Checking the External
ServerNet X and Y Fabrics on page 7-29.
9. If the alarms persist, perform the repair actions for clearing the alarms.
