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
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
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.
