SCSI Media Devices

A SCSI media device can be placed in the SCSI media-device bay. If a SCSI media device is installed in
the system, then a power cable and a SCSI cable will be connected to the rear of the SCSI media device
and routed to the appropriate connectors on the rear of the media-bay-chassis backplane or PCI adapter.
If the SCSI media device is connected to a audio card, then a cable will be connected to the rear of the
SCSI media device and routed through the system to the audio card. If the SCSI media device is a
DVD-RAM, then a single-ended cable will be connected to the rear of the DVD-RAM and routed through
the system to a single-ended (SE) SCSI adapter. See the illustration on page 274.
Removing a SCSI Media Device
To remove a SCSI media device, do the following:
1. Shut down the system as described in "Stopping the System" on page 246.
2. Disconnect the power source from the system.
Note: This system may be equipped with a second power supply. Before continuing with this
procedure, ensure that the power source to the system has been completely disconnected.
3. Place the system into the service position as described in "Placing the Model 275 into the Service and
Operating Position" on page 248.
4. Remove the front bezel as described in "Bezels" on page 251.
5. Remove the media bay chassis as described in "Media Bay Chassis" on page 285.
