Upgrading and Repairing Servers

The Intel SC5295-E chassis is a typical pedestal chassis, closely resembling an ATX tower chassis in many ways. It can also be converted into a 4U rack-mounted chassis. However, the following sections deal with chassis removal, as it applies to the default pedestal configuration.

This particular chassis, like many recent Intel chassis, is designed to be opened without special tools, making access to the interior easier than with older chassis. Before removing any part of the chassis, you need to be sure to shut down the system, disconnect it from AC power, and put on a wrist strap.

Removing the Left Side Panel

As with ATX tower chassis, you must open the SC5295-E's left side (as seen from the front) to gain access to the interior. After the left side is removed, you can replace the motherboard, install memory, and perform other types of maintenance.

To remove the left side panel, follow these steps:

1.	Remove two screws from the back edge of the panel.
2.	Push in on the latch near the top of the panel.
3.	Pull the panel toward the rear of the system (see Figure 15.13). Figure 15.13. Removing the left side panel of the Intel SC5295-E server chassis.
4.	After the left side panel is open, attach the alligator clip from the wrist strap to a metal portion of the chassis.

Removing the Front Bezel Assembly

Some versions of the Intel SC5295-E server chassis use a two-piece bezel, while others use a one-piece bezel (see Figure 15.14). In either case, follow these steps to remove the bezel after the left side cover is removed:

Push inward on the two bezel clips on the left side of the bezel to release them.

Turn the bezel slightly to the left.

Push inward on the three bezel clips on the right side of the bezel.

If the bezel is wired to the motherboard, try to place the bezel close enough to the server that you don't need to disconnect motherboard wires. Otherwise, note the position of the wires and disconnect them. You will need to reconnect them later.

Removing the Air Ducts

Most versions of the Intel SC5295-E server chassis have removable air ducts (except for the UP version, which has the air ducts built into the left side panel). Before you can install a processor or motherboard, you must remove the air ducts. The left side panel must be removed first.

If the server chassis uses a small air duct as well as a large air duct, it must be removed first. Unscrew it from the area behind the 3.5-inch internal drive bay and remove it. The small air duct is labeled "Part B."

To remove the large air duct ("Part A"), remove the two mounting screws (see Figure 15.15).

Removing the Drive Cage EMI Shield

You must remove the drive cage EMI shield before you can do any of the following:

Install a new motherboard

Install 3.5-inch hard disk drives

Install a hot-swap drive array

The drive cage EMI shield is located behind the front bezel. The front bezel must be removed first.

To remove the EMI shield, unscrew the hold-down screw on the right side of the EMI shield and pull the shield forward (see Figure 15.16).
