Deployment Guide

Add an SCv300 and SCv320 Expansion Enclosure to the A-

Side of the Chain

Connect the expansion enclosure to one side of the chain at a time to maintain drive availability.

Steps

1. Turn on the expansion enclosure being added. When the drives spin up, make sure that the front panel and power status LEDs show

normal operation.

2. Disconnect the A-side cable (shown in orange) from the expansion enclosure: top EMM, port 2. The B-side cables continue to carry

I/O while the A-side is disconnected.

4. Connect the A-side cable that was disconnected in step 2 to the new expansion enclosure (2): top EMM, port 2.
