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 use this procedure to 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.
Procedure
Removing a SAS cable
1. Locate the connector at the end of the SAS cable that is to be removed from the expansion enclosure.
2. Grasp the connector by its blue tag. Pull the tag.
3. Release the connector and slide it out of the SAS port.
