Chapter 5 Installation and Configuration Note the cable requirements for the HP NetRAID-3Si: • The external connectors for Channels 0 and 2 on the HP NetRAID-3Si are very close together and require D6020A cables with offset connectors. Some nonstandard cable configurations and switch settings are listed in the HP NetServer user guides. Refer to the mass storage section of your system documentation for details on HP NetServer configurations. Use the lowest SCSI ID numbers first. Set the SCSI ID switches on the back of each drive cage. On many systems, it is easier to reach the SCSI ID switches if you pull the drive cage at least halfway out. A flashlight and small metal pin, such as a straightened paper clip, will help to manipulate the switches. A magnifying glass may help you see them. Avoid problems with your SCSI devices and adapter by observing the following rules: • Never set any SCSI device ID to 7, because 7 is reserved for the SCSI controller. • For HP NetRAID and HP NetRAID-1 adapters, connect a maximum of six or eight (depending on the type of enclosure used) Fast/Wide or Ultra SCSI devices to each channel, and set their SCSI IDs between 0 and 15, but not to 7. • For HP NetRAID-3Si adapters, connect a maximum of six or eight (depending on the type of enclosure used) Fast/Wide, Ultra SCSI, or Ultra2 SCSI devices to each channel. Set their SCSI IDs between 0 and 15, but not to 7. • See HP Order Assistant for non-hot swap disk support. HP Order Assistant is available on the Internet at www.hp.com/go/netserver/order. • Connect the CD-ROM drive to the embedded SCSI controller. 51

•
The external connectors for Channels 0 and 2 on the HP NetRAID-3Si are
very close together and require D6020A cables with offset connectors.
Some nonstandard cable configurations and switch settings are listed in the HP

.
Refer to the mass storage section of your system
documentation for details on HP NetServer configurations. Use the lowest SCSI
ID numbers first.
Set the SCSI ID switches on the back of each drive cage. On many systems, it is
easier to reach the SCSI ID switches if you pull the drive cage at least halfway

to manipulate the switches. A magnifying glass may help you see them.
Avoid problems with your SCSI devices and adapter by observing the following
rules:
•
Never set any SCSI device ID to 7, because 7 is reserved for the SCSI
controller.
•
For HP NetRAID and HP NetRAID-1 adapters, connect a maximum of six
or eight (depending on the type of enclosure used) Fast/Wide or Ultra
SCSI devices to each channel, and set their SCSI IDs between 0 and 15,
but not to 7.
•
For HP NetRAID-3Si adapters, connect a maximum of six or eight
(depending on the type of enclosure used) Fast/Wide, Ultra SCSI, or
Ultra2 SCSI devices to each channel. Set their SCSI IDs between 0 and
