Removing and installing a SAS cable: 2077-92F, 2077-A9F

Use the following procedures to attach SAS cables to the 2077-92F, 2077-A9F 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.
When the 2077-92F, 2077-A9F 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.
