Installing the SF72 Storage Enclosure in an SF200 Storage Array 5–3

5.1 Steps to Install

The following procedures assume that the existing SF200 storage array is

correctly installed and conﬁgured.

The SF72 storage enclosure that you are installing may contain two

or four RF72 disk ISEs. To determine if the SF72 contains two or four,

simply look at the front of the enclosure. Open the front door of the SF200

storage array. If you can see two disk ISEs in the front of the SF72, then

the enclosure contains four ISEs (SF72–JK variant). If you do not see

two ISEs in the front of the enclosure, then that enclosure contains only

two ISEs (SF72–HK variant). If you wish to verify an enclosure that is

already installed in a cabinet or array, observe the number of 7-segment

displays that are lit on the operator control panel (OCP). If the top two

displays are lit, then the enclosure contains only two RF72 disk ISEs.

This section contains several major parts. The ﬁrst part explains the

steps to:

• Unpack, inspect for damage, and identify parts

• Determine where to install the SF72 enclosures

• Read and ﬁll out the system conﬁguration sheet

The next part explains the steps to install the SF72 enclosure itself:

• Prepare the array cabinet to receive an SF72 storage enclosure

• Install the supporting hardware and SF72, and set the DSSI ID

switches

• Cable the SF72 storage enclosure to comply with the DSSI bus cabling

conventions
