Appendix C: Upgrading the Qube 3
212 Cobalt Qube 3 User Manual
Hard disk drives
The Qube 3 and Qube 3 Business Edition ship with one hard drive disk; the
Qube 3 Professional Edition ships with two hard disk drives and offers RAID-1
disk mirroring.
If you have a Qube 3 Professional Edition and one of the hard drive fails, the
failed hard disk drive (Drive A or Drive B) is indicated in the Server Desktop
under the Active Monitor function. If you are replacing a failed hard disk drive,
remove the guide rails from the old hard disk drive and attach them to the new
drive. See Figure 106, #4.
Precautions
Keep in mind the following items while upgrading your Qube 3:
• DIMMs, PCI cards and hard disk drives are sensitive electronic devices. Be
careful not to damage them or other components during the upgrade.
• Do not force the insertion of an electronic device. If it does not insert
properly with moderate effort, check all alignments and insertion directions.
Forcing a component can damage both the device and the Qube 3, and can
void your warranty.
!
Caution: The Qube 3, like all electronics, is extremely sensitive to
electro-static shocks. Ground yourself by touching a piece of metal,
such as the Qube 3 chassis, before handling any electronics.
