5–4 Installing the SF72 Storage Enclosure in an SF200 Storage Array

The last part explains the steps to:

• Power up the SF72 enclosure, run the power-on self-test, and run the

conﬁguration programs

• Label all cables and operator control panels

• Verify the operation of the enclosure after a successful installation

Follow all the steps in each of these parts in the order they are presented

and do not skip any steps.

When the array is to operate in a single-host conﬁguration, remember

that the enclosure in positions 1, 2, 4, and 7 operates in the through-bus

mode. To ensure that the SF72 storage enclosure you are installing is

in the through-bus mode after the installation is complete, observe the

bottom indicator on the OCP. It should be off. Positions 3 and 8 operate

in the split-bus mode and require you to reconﬁgure their transition

termination module (TTM). That same indicator should be on once the

enclosure is set for split-bus mode. The procedure to accomplish this is

presented later in this chapter.

When the array is to operate in a dual-host conﬁguration, remember that

all enclosures operate in the through-bus mode.

5.1.1 Unpacking the SF72 Storage Enclosure

Unpack the SF72 shipping container. The enclosure is shipped in an

environmental barrier bag with desiccant.

NOTE

After unpacking, retain the container and all packing materials.

At this time, examine the enclosure for physical damage. If you ﬁnd

any damage, do not attempt to install the enclosure. Notify your ofﬁce

immediately.

If there is no damage, then unpack all the boxes and bags, and identify

all the parts by using Table 5–2.
