Installation guide

5.1 Steps to Install
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 SF7x enclosures
• Read and fill out the system configuration sheet
The next part explains the steps to install the SF7x enclosure itself:
• Prepare the array cabinet to receive an SF7x storage enclosure
• Install the supporting hardware and SF7x, and set the DSSI ID switches
• Cable the SF7x storage enclosure to comply with the DSSI bus cabling
conventions
The last part explains the steps to:
• Power up the SF7x 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
enclosures SF1, SF2, SF4, SF5 operates in the through-bus mode. To be sure
that the SF7x 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. SF3 and SF6 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 SF7x Storage Enclosure
Unpack the SF7x shipping container. The enclosure is shipped in an
environmental barrier bag with desiccant.
Note
After unpacking, retain the container and all packing materials.
