Removing and installing a SAS cable: 2145-92F
Use the following procedures to attach SAS cables to the 2145-92F enclosure during
the initial installation process. You can also remove a faulty SAS cable and replace
it with a new one received from FRU stock.
About this task
Be careful when you are replacing the hardware components that are located in the
back of the system. Do not inadvertently disturb or remove any cables that you are
not instructed to remove.
If you replace more than one cable, record which two ports, canisters, and
enclosures each cable connects, so you can match the connections with the
replacement cables. The system cannot operate if the SAS cabling to the expansion
enclosure is incorrect. See the Installing container of the IBM Knowledge Center for
information about the correct SAS cabling for expansion enclosures.
When the 2145-92F expansion enclosure is installed in the rack, the expansion
canisters are upside down. The input cable connects to the right port (port 1) on
the expansion canister. The output cable connects to the left port (port 2) on the
canister.
