Removing the bezels
To remove either the left or right bezel, complete the following steps:
1. If the storage subsystem is on a table or other flat surface, elevate the storage
subsystem front slightly or extend the front over the table edge.
2. Grasp the handle on the front of the bezel and pull until the bezel is clear of the
bottom tab on the chassis flange.
3. Lift the bezel off the chassis flange.
Installing the bezels
To install either the left or right bezel, complete the following steps:
1. Fit the cutout that is on the top of the bezel over the tab on the chassis flange.
2. Rotate the bezel down until it snaps into place. Make sure that the inside
surface of the bezel is flush with the chassis.
Working with environmental service modules
This section describes how to add or replace an ESM.
Installing an additional ESM
The expansion enclosure comes with one environmental services module (ESM). If
your RAID controller supports redundant drive paths (see the documentation that
comes with the RAID controller or the device that contains the RAID controller), you
can install a second ESM.
To install a second ESM, complete the following steps:
1. Read the safety information that begins on page xiii and “Best practices
guidelines” on page 5.
2. Remove the ESM filler panel from the rightmost ESM bay:
a. Open the two release levers. The ESM filler panel moves out of the bay
approximately 0.6 cm (0.25 inch).
b. Slide the ESM filler panel out of the bay and set it aside.
3. Place the ESM on a level surface.
4. Make sure that the release levers on the ESM are in the open position.
