Note:
1. Make sure that the bottom edge of the chassis rail is aligned with the bottom U that
you want the chassis to rest on.
2. If you misalign the chassis rail, press the locking hooks release or squeeze the locking hooks
on the chassis rail, slide the posts out of the holes, and try again.
3. Make sure that the chassis rail posts protrude through the holes
on the front EIA flange.

Pull the chassis rail forward and insert the posts on the front of the chassis rail into the
holes on the front EIA flange until it snaps into place. Repeat steps 2.4 and
2.5 for the right chassis rail.
Verify the shipment contents:
1.2
Become familiar with the chassis components. The following modules are standard:
One
System Chassis Management Module (CMM), two or more power supplies, six or more fan modules, and two fan logic modules. The chassis might
also include one or more compute nodes, storage nodes, and a management node. The features or modules that you receive might differ from the contents
shown in Figures 1 and 2, depending on what you ordered (see Figures 1 and 2).

To decrease the weight and make the chassis easier to install in a rack, remove
components from the chassis. Make a note of each component location so that
the component can be reinstalled in the same location. Press on the colored
latch and pull on the handles to remove the components. You can also remove
the shelves from the chassis to reduce the weight further.
4. Install an M5 combi-head screw in each end of the rail.
Use the lower threaded hole on the front and the upper
threaded hole on the rear.

Align the rack template with the holes in the EIA flange (internal to rack).
For EIA flanges with square holes, install M5 cage nuts from the accessory
kit in the holes that are indicated on the template. If the EIA flanges have
round holes, install the M5 clip nuts from the accessory kit instead of the
M5 cage nuts.
Note:
Install cage nuts or clip nuts on the front and back EIA flanges.
• Make sure that there is sufficient room in front of the front EIA flange to
provide minimum bezel clearance of 50 mm (1.97 inches).
•
EIA flanges to 719 mm (28.3 inches) outside to outside.
If you have an adjustable rack, set the distance between the front and rear
