Rack-Mounting
Refer to the important guidelines below before installing the OmniSwitch 7700/7800 chassis in a rack.
• Be sure that all modules and power supplies are removed before rack-mounting the switch. For instruc-
tions on removing CMM or NI modules, refer to Chapter 5, “Network Interface (NI) Modules.” For
instructions on removing power supplies, refer to “Removing a Power Supply” on page 2-26.
• Rack-mounting the chassis requires three people—two people to hold the chassis and position it in the
rack and a third person to secure the chassis to the rack using the attachment screws.
• The chassis has two integral rack-mount flanges that support standard 19-inch rack mount installa-
tions. Refer to page 2-11 for information on optional rack-mounting hardware.
• Alcatel 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 the rack manu-
facturer’s specifications.
• Refer to page 2-9 for important chassis airflow recommendations before installing.
To rack-mount the switch, follow the steps below:
1 Mark the holes on the rack where the chassis is to be installed.
2 Using two people, lift and position the chassis until the rack-mount flanges are flush with the rack post.
3 Align the holes in the flanges with the rack holes you marked in step 1.
4 Once the holes are aligned, use a third person to insert a screw through the bottom hole on each flange.
Tighten both screws until they are secure.
Note. Be sure to install the screws in the bottom hole of each flange, as shown, before proceeding.
