Using the Hot Plug Feature
The faulty drive indicator on the hot plug drive tray lights up whenever the
drive that it carries becomes bad or defective. When this happens, you can
replace the defective drive without shutting off the system or quitting any
running application by using the hot plug feature.
To use the hot plug feature, follow these steps:
1. Set the hot plug drive tray power switch to the Unlock/Power Off
position.
2. Pull out the drive tray.
3. Take out the defective drive from the tray.
4. Configure the new hard disk. Make sure that the new drive ID is the same
as the old drive ID.
5. Install the new disk according to the installation steps in the “Installation”
section of this appendix.
Note: Make sure that the power switch on the drive tray is set to the
Unlock/Power Off position before you plug it to the backplane board.
