5. Set the bracket with the attached hard disk drive on the chassis and slide it
onto the metal tabs. The connectors on the hard disk drive must face in to the
center of the chassis, with the foam pad located next to the power supply.
6. Re-attach the bracket to the chassis with the correct screw.
Connecting the hard disk drive
To connect the hard disk drive:
1. Remove the cap from the Y-connector power cable.
2. Plug the Y-connector power cable into the hard disk drive, see Figure 62. The
connector is keyed to fit into the hard disk drive one way only.
3. Plug the IDE cable into the hard disk drive; see Figure 61. The connector is
keyed to fit into the hard disk drive one way only.
Replacing the top cover and rebooting the RaQ 4
To replace the top cover and reboot the RaQ 4:
1. Secure the top cover properly and replace the ten screws that hold the top
cover in place. See Figure 59 on page 162.
2. Reconnect the power cord to the rear of the RaQ 4.
3. Power up the RaQ 4. The RaQ 4 boots up in the normal manner.
If you have added a second hard disk drive to a RaQ 4i server, you now have to
add (through the RaQ 4 UI) the second drive to the list of available storage
devices; see “Storage” on page 82.
✍
Note: If you have replaced a failed hard disk drive in a RaQ 4r
server, you do not need to add the new hard disk drive through the
Add Storage feature. When rebooting, the system automatically
detects the new hard disk drive.
The RaQ 4r automatically synchronizes the new hard disk drive to
the existing hard disk drive so that the server will be able to provide
disk mirroring. During the synchronization process, the RaQ 4r
cannot provide disk mirroring but it can still serve requests.
