Replacing the internal-cable-management arm

To install the replacement internal-cable-management arm, complete the following
steps:
1. Insert the bottom tab of the internal-cable-management arm into the lower pivot
2. Rotate the top of the arm toward the front of the server, insert it into the top
3. Route the SAS signal cable or cables through the internal-cable-management
4. Install the bezel and front cover (tower model only) (see "Replacing the top
5. Connect the cables and power cords (see "Connecting the cables" on page 116
6. Turn on all attached devices and the server.

Important: The following minimum code levels must be installed for the server
to support the dual-core upgrade:
Basic input/output system (BIOS) code level ZUJT53A
Remote Supervisor Adapter II (RSA2) firmware level ZUEP37B
Baseboard management controller (BMC) code level Z2BT05D
Complex programmable logic device (CPLD) firmware level HEUD18A
Diagnostic program (Diags) code level ZUYT26A
The server model number will change when you install this upgrade. A new label
comes with the option kit for you to place over the existing label on the server.
The following table lists the kit server model numbers before and after the
dual-core upgrade is installed.
