• For backplane connectors with locking ears, open the locking ears before
inserting the SCSI cable.
ΝΟΤΕ For HP NetRAID-3Si, the external connectors for Channels 0
and 2 are very close together and require D6020A cables with
offset connectors.
Some nonstandard cable configurations and switch settings are listed in the
HP NetServer documentation. Refer to the mass storage section of your system
documentation for details on HP NetServer configurations.
If you need to set the SCSI ID, 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. Set their SCSI IDs between 0 and 15, but not to 7.
• Connect a maximum of six, eight, or twelve (depending on the type of
enclosure used) Fast/Wide, Ultra SCSI, or Ultra2 SCSI devices to each
channel.
• See HP Order Assistant for non-hot swap disk support. HP Order
Assistant is available on the Internet at

.
• Do not connect a CD-ROM drive to an HP NetRAID Series adapter.
• Do not connect a tape drive to an HP NetRAID Series adapter.
