Installing A Second Hard Disk Drive In An Internal
Shelf
The internal hard disk shelves, located just under the floppy drive, can support two
3.5-inch devices.
To install a second hard disk drive:
1. Switch off the display and workstation. Disconnect all power cables and any LAN or
telecommunications cables.
2. Remove the workstation’s cover (refer to page 119 for instructions).
3. If the boot IDE hard disk drive is installed in the lower shelf, disconnect the data
and power cables. Move the boot drive to the upper shelf and install the secondary
drive in the now empty lower shelf. This is not necessary if the drive is a SCSI drive.
4. Attach the blue rails (found on the CD cage) to the new hard disk drive. Insert the
guide rail labeled “L” on the left-hand side (cable connectors facing towards you and
positioned at the bottom), and the guide rail “R” on the right-hand side of the hard
disk drive.
5. You can insert the second hard disk drive only one way. Make sure the data and
cable connectors are facing you and positioned at the top.
6. Align the guide rails on both sides of the drive with the internal shelf guides and
then slide the drive into the bottom shelf until it clicks into position.
NOTE Avoid trapping or disconnecting the hard disk drive bay thermal sensor cable. If this
cable becomes disconnected, reconnect it to the system board connector labeled
THERMAL_SENSOR (positioned near the IDE and Floppy data cable connectors.
7. Connect the power and data cables to the second hard disk drive. Reconnect the
power cables and the data cable to the boot hard disk drive.
8. Replace the workstation’s cover (refer to page 119). Reconnect all the power and
telecommunications cables.Turn to page 138 to complete the installation.
