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.
4. Repeat steps “2” on page 52 and “3” on page 52 on the other end of the SAS cable.

5. Ensure that the SAS connector is oriented correctly, as shown in Figure 47 on page 52. The blue tab
must face towards the top of the enclosure canister.

Connecting to a system node
7. Connect the SAS cable to the SAS port with blue tab above the connector (that is, facing towards the
top of the node).
You hear or feel a click when the cable is successfully inserted. You cannot disconnect the cable
without pulling on the blue tag.
8. Route the SAS cables through the cable management arms, as shown in Figure 48 on page 52.

9. When both ends of a SAS cable are correctly connected, the green link-LED next to the connected SAS
ports are lit.
For example, Figure 49 on page 53 shows the LEDs of expansion canister 1 on a 5U expansion
enclosure. The SAS cable is successfully inserted in to port 1 (input); port 2 (output) does not contain a
SAS cable.
