ÅWARNING:
Any surface or area of the equipment marked with this symbol indicates the presences of a
hot surface or hot component. If this surface is contacted, the potential for injury exists. To reduce the risk of
injury from a hot component, allow the surface to cool before touching.
ÅWARNING:
Any surface or area of the equipment marked with this symbol indicates the presence of an
electrical shock hazard. To reduce the risk of injury from electrical shock, do not open any enclosed area.
ÄCAUTION:
Static electricity can damage the electronic components of the workstation. Before beginning
these procedures, be sure you are discharged of static electricity by briefly touching a grounded metal
object.
Step 1—Prepare the Workstation

Step 2—Install the SAS Rear Panel Cable
After you have prepared the workstation for installation, perform the following steps to install the SAS rear
panel cable.
ÄCAUTION: Do NOT connect the SAS rear panel cables to the SATA connectors. Only connect the SAS
rear panel cables to the SAS connectors; otherwise, the hard drives will not function.
Locate the SAS connectors by reviewing the system board layout illustration on the access panel. Use the
following illustration only as an example, not as a guide to connector location.
1. Attach the SAS cables of the SAS rear panel cable assembly to the SAS connectors 1on the system
board.
❏If all four connectors are not available because you already have SAS devices installed, connect
the cable assembly to the remaining free connectors. Bandwidth will be proportional to the
number of connectors attached.
2. Use a mounting screw 2to attach the MiniSAS 4X connector of the SAS rear panel cable assembly to
the rear of the chassis.
Step 3—Reassemble the Workstation
After installing the SAS rear panel cable, reassemble the workstation using the instructions in the
workstation documentation. The reassembly process involves reinstalling the side access panel, and
restoring power to your unit.
