Basic Marathon Hardware Replacement
Replacing the MIC Cable
There are a number of components that can be affected by a failed
MIC cable. The IOP or CE to which the cable is attached will be in
a degraded state. Make sure to examine all components to make sure
the failed cable is the only component that is bad.
Once you have acquired a replacement cable, shut down the system
where the cable is attached. Make sure you follow the proper
shutdown procedures for the CE or IOP.
1. Remove the cable from the SSDL and the IOP or CE.
2. Install the new cable.
3. Examine the lights on the front of the SSDL to ensure cable
connection.
4. Power on the CE or IOP and use the Marathon Manger to re-
enable the any faulted or disabled components.
5. Examine the status of all components to ensure they are active or
online.
If the system that was affected was an IOP a re-mirror will occur.
Replacing the TL Cable
The TL (Tuple Link) cable connects the SSDLs together. To replace
a TL cable:
1. Obtain a replacement cable.
2. Decide which tuple can be removed with the least impact to your
system, and issue a Marathon Manager Tuple Disable command
for that tuple.
3. On both SSDLs, remove the TL cable by loosening the
connector screws and detaching the cable.
4. Install the new TL cable by attaching it to appropriate DataLink
connectors on both SSDLs and tightening the connector screws.
5. On each SSDL, make sure that the status lights in column 1 and
2 are lit green.
6. If one of these status lights is red or not lit, correct the condition
and continue.
7. Issue a Marathon Manager Tuple Enable command for the tuple.
8. If necessary, use Marathon Manager to enable any faulted MSIs.
9. Use the Marathon Manager: to make sure that any components
affected by this procedure are active or online.
