Installing or replacing an optical drive

Attention: Do not open your server or attempt any repair before reading and understanding the “Safety information” on page iii and “Guidelines” on page 83.

This topic provides instructions on how to install or replace an optical drive.

The EMI integrity and cooling of the server are protected by having all drive bays covered or occupied. Your server has two optical drive bays. If only one optical drive is installed in the lower bay, the upper bay is covered by a metal EMI shield on the chassis and also a plastic shield on the front bezel. When you install a secondary optical drive or a RDX USB drive bundle, save the removed EMI shield from the chassis and plastic shield from the front bezel in the event that you later remove the drive and need the shields to cover the drive bay.

Attention: An unoccupied drive bay without any other protection might impact the EMI integrity and cooling of the server, which might result in overheating or component damage. To maintain the EMI integrity and cooling of the server, install a new optical drive as soon as you remove the failing one or the protective shields.

CAUTION:

When laser products (such as CD-ROMs, DVD drives, fiber optic devices, or transmitters) are installed, note the following:

•Do not remove the covers. Removing the covers of the laser product could result in exposure to hazardous laser radiation. There are no serviceable parts inside the device.

•Use of controls or adjustments or performance of procedures other than those specified herein might result in hazardous radiation exposure.

DANGER

Some laser products contain an embedded Class 3A or Class 3B laser diode. Note the following.

Laser radiation when open. Do not stare into the beam, do not view directly with optical instruments, and avoid direct exposure to the beam.

Before you begin, consider the following optical drive installation rules:

•The server has two optical drive bays. If the server has only one optical drive installed, make sure that the optical drive is installed in the lower bay (optical drive bay 1). The upper bay is for a secondary optical drive or a RDX USB drive bundle (server option).

•The following table provides information about the recommended power connector and connector on the system board for the installed optical drive or RDX USB drive bundle. See “Server components” on page 25 for the locations of the optical drive bays and “System board components” on page 42 for the locations of the connectors on the system board.
