Chapter 2 Preparing for Installation and Assembling the Cables 19
Hardware Requirements
You must have the following hardware at your site to successfully install your
StorEdge S1 storage enclosure:
■
A host system with either an LVD or a single-ended UltraSCSI on-board port, or
■
A SCSI host adapter board installed in the host system.
For LVD (Ultra 2/3) SCSI functionality, the host or host adapter to which you
connect your StorEdge S1 storage enclosure must be capable of LVD (Ultra 2/3) SCSI
speeds. You can connect a StorEdge S1 storage enclosure to a wide or narrow SCSI-
capable host adapter, but in such a case, the enclosure performs at a lower speed.
Tools and Equipment Needed
■
An 8mm wrench (for assembling the rackmounting rails)
■
A No. 2 Phillips screwdriver
■
A small flat-head screwdriver (to install DC input cables, if necessary)
■
An ESD pad and an antistatic wrist strap
Determining the Number of Units to Install
If the StorEdge S1 units are installed on a host system or host adapter LVD SCSI
port, up to four StorEdge S1 units can be installed.
There are limitations to the number of StorEdge S1s that can be installed in the
following situations:
■
If the SCSI port is single-ended, you can install no more than two StorEdge S1
units on the SCSI chain.
■
If there is a single-ended device already on the SCSI chain, or a single-ended
device will be installed along with the StorEdge S1 unit, you can only install one
StorEdge S1 storage enclosure on the chain along with the other peripheral.
