Duplexing Hard Drives
You may choose to duplex the drives in the HP NetServer’s removable hard disk
drive cage (only four drives possible). The NetServer supports an option to duplex
the drives using the embedded dual channel SCSI controllers (SCSI A and B).
There must be at least two SCSI drives available in the hard disk drive cage to
duplex the drives. The NetServer also supports HP’s NetRAID-1Si PCI Controller
board to control the two duplexed channels.
CAUTION To prevent damage to the embedded SCSI controller, don’t use
a HVD (high voltage differential) device.
If the duplexing option is required using the two embedded SCSI channels, refer
to "Installing the Optional SCSI Accessory Cable Kit " later in this chapter for
instructions on how to install the duplexing cable. If you choose to use an HP
NetRAID-1Si PCI Controller board, refer to the documentation provided by the
RAID controller board for cabling requirements.
Installing Hard Disk Drives
1. If the NetServer is already installed and operating, power down the
NetServer as described in Chapter 1, "Controls, Ports, and Indicators."
2. Disconnect the power cables and any external cables connected to the
NetServer.
If necessary, label each one to expedite re-assembly.
3. Remove the cover and turn in the NetServer feet inward as described in
Chapter 2, "Opening and Closing the HP NetServer."
This allows the NetServer to lie flat when turned on its side.
4. Lay the NetServer on its side (components showing).
5. Unlatch the air duct and move it out of the way. See Figure 3-1.
