Rack-Mounting Chassis and Power Supplies
Rack-Mounting
Refer to the following important guidelines before installing the chassis in a rack:
•
Two people are required to rack mount the switch: One person to lift the chassis into position and one person to secure the chassis to the rack using the rack mount screws.
•
•
•
The chassis has rack-mount flanges that support standard 19-inch rack mount installations.
Alcatel-Lucent does not provide rack-mount screws. Use the screws supplied by the rack vendor.
To prevent a rack from becoming top heavy, it is recommended that you install the switch at the bottom of the rack whenever possible.
•
If you are installing the switch in a relay rack, be sure to install and secure the rack per rack manufacturer’s specifications.
To rack mount the switch, follow the steps below.
Note. Because of the overall chassis depth, additional support braces are used to support the rear of the chassis and prevent sagging in the rack. These braces are required for all rack-mound installations.
1
Mark the holes on the rack where the chassis is to be installed.
2
Attach two slot rails to the left and right side of the chassis.
3 One person should lift and position the chassis until the rack-mount flanges are flush with the rack post.
4
Align the holes in the flanges with the rack holes marked in step 1.

5
Once the holes are aligned, the second person should insert a screw through the bottom hole on each flange. Tighten both screws until they are secure.
6
From the back of the chassis and with the flanges facing out, insert the slide-in braces into the slot rails until they meet the rack posts.
7 The chassis installation should be level. Be sure that the holes and flanges of the slide-in brace are aligned with the corresponding holes at the front of the rack.
8
Once the flanges are aligned, install the remaining screws in all four flanges. Be sure that all screws are securely tightened.

Standalone (Non-Rack Mounted) Installations
The chassis can also be placed unmounted on a stable, flat surface as a standalone unit. Be sure that the surface can accommodate the full, populated weight of all switches being installed. Approximate chassis weights are provided on
.
For a standalone unit, use two or more people to move and position the unpopulated chassis upright on the surface where it is to be installed. Be sure that adequate clearance has been provided for chassis airflow and that you have placed the chassis within reach of all required AC outlets. For recommended airflow allowances, refer to
.
Note. Chassis must be placed “right side up.” Never attempt to operate a switch while it is placed on its top or side.
