Installing or replacing the rear I/O module Attention: Do not open your storage array or attempt any repair before reading and understanding "Safety information" on page iii and "Guidelines" on page 31. This topic provides instructions on how to install or replace an I/O module. To install or replace an I/O module, do the following: 1. Disconnect all power cords from electrical outlets and disconnect all cables that are connected to the storage array. Note: If your storage array has two I/O modules installed, you can replace the failing I/O module with the power on. 2. Do one of the following: • If you are installing an I/O module, locate the bay for the I/O module in the rear of your storage array. • If you are replacing an I/O module, locate the failing I/O module in the rear of your storage array. Then, loosen the screws and pivot them as shown to pull the failing I/O module out of the chassis. Figure 31. Removing an I/O module 3. Touch the static-protective package that contains the new I/O module to any unpainted surface on the outside of the storage array.
