5-12 Sun StorEdge T3 Disk Tray Installation, Operation, and Service Manual • July 2000
Note – Even if the LED indicates an interconnect card failure, you should always
verify the FRU status using either the CLI or Component Manager before replacing
the unit. Refer to the Sun StorEdge T3 Disk Tray Administrator’s Guide or Sun StorEdge
Component Manager User’s Guide for more information.
5.2.4.2 Removing and Replacing an Interconnect Card
Caution – The interconnect cables must be used only to cable Sun StorEdge T3 disk
trays together using the interconnect card connectors. Do not use these cables for any
other FC-AL connection.
Caution –
The interconnect card FRUs are extremely sensitive to static electricity.
Use proper grounding wrist straps and antistatic procedures when handling these
FRUs. See Section 5.1 “Preparing for Service” on page 5-2 for a list of static electricity
precautions.
Caution –
Replace one interconnect card at a time. Follow the procedure as
described to ensure that there is no interruption in system operation or loss of data.
To prevent interruption of system operation during interconnect card replacement,
make sure that:
■
In a single controller unit configuration, remove only the failed interconnect card.
Leave the second interconnect card intact in the disk tray.
Caution –
Removing both interconnect cards at the same time in a single unit will
cause the unit to shut down immediately. Remove only one card at a time.
■
In a partner group, remove the interconnect cable only from the failed
interconnect card. Leave the interconnect cable attached to the working
interconnect card.
To replace an interconnect card:
1. Ensure that the interconnect card to be replaced is showing failure status.
2. Observe static electricity precautions.
If you have a single controller unit configuration, proceed to Step 4.
