3.3 Field-Replaceable Units
Check that you received all field-replaceable units (FRUs) ordered with your
SANnet II 200 SCSI array. For additional FRUs, consult your sales representative. For
instructions on how to install or replace FRUs, review the following manuals located
on the product web site:

SANnet II 200 Family Rack Installation Guide for 2U Arrays
■
SANnet II Family FRU Installation Guide
Caution –
You can mix capacity in the same chassis, but not spindle speed revolutions
per minute (RPM) on the same SCSI bus. For instance, you can use 36-Gbyte and 73-
Gbyte drives with no performance problems if both are 10K RPM drives. Violating this
configuration guideline leads to poor performance.
For a list of the FRU part numbers, refer to the SANnet II Family FRU Installation
Guide .
3.4 Customer-Provided Cables
Customers must provide the following cables.
■
One Ultra 160 SCSI cable per host to connect a host to a RAID array, expansion
unit or JBOD; up to two host cables might be needed per array.
To obtain qualified cables, consult your Dot Hill sales representative.
3.5 Mounting Your Array in a Rack or Cabinet
