Installation Procedures

This guide contains the information necessary to install, test, and troubleshoot (if necessary) the Redundant Power Upgrade. This guide is written for knowledgeable users, trained customer engineers, system analysts, service center personnel, and dealers.

With the upgrade kit installed, the server will have power system redundancy that allows the system to operate with a single power supply failure. Also, when the additional redundant power supply is installed, both the standard and additional redundant power supply slots become hot swappable.

Please read these installation procedures in their entirety before starting.

4 Redundant Power Upgrade Kit Installation Procedures

Removing the Server Side Panels

To install the redundant power upgrade in the server, the server side panels must be removed. Also, please note that the right side panel removes in the same manner as the left side panel.

CAUTION

For proper cooling and airflow, do not operate the system with the side panels removed. Always replace the panels before powering on the system.

WARNING

Before removing the server covers, turn off the power and unplug the system power cables. Power is removed only when the power cables are unplugged.

To remove a side panel:

1. Unlock and open the server front door (tower version only).

2. Close all programs in use and shutdown the operating system.

3. Turn off power to any peripheral devices.

4. Power off the server by pressing the power button on the front of the server.

The power indicator goes out.

5. Disconnect all cables from the back of the server and unplug all power

cords. The power supply status indicators go out.

6. The side panel is secured to the chassis with three thumbscrews (see figure

below). Loosen the thumb screws securing the side panel

7. Slide the side panel toward the rear of the chassis. This unlocks the locking

fingers behind the side panel.

8. Pull the side panel out and away from the chassis.
