Prepare for Rack Installation
The minimum distance between left and right mounting rails (as you face the rack) must be 17.75 inches
or 45.08 cm. (Some 19-inch racks have only 17.50 inches betw een the rails.) The width of the
components, such as the card cage and fan tray, is 17.72 inches.
When installing a MGX 8830 system in a 19-inch rack, adhere to the following guidelines:
•Open-rack configuration—The switch and optional AC power supply tray need to b e mid-mounted
in the rack. Brackets for that purpose are included with the system.
•Cisco cabinet configuration—The switch and optional AC power supply tray are shipped
front-mounted in the enclosure, and the rear of each component is supported by a rear bra cket.
When you are installing a MGX 8830 system in a 23-inch rack, the switch and optional AC power supply
tray need to be mid-mounted in the rack. You need special mounting brackets to mid-mount the
components in a 23-inch rack (mounting kit, Cisco Part Number M GX-8830-MNT23).
Figure 5-69 shows the mounting rail distances for front, middle, and rear mounting rails.

Tip If a component requires more than two screws for installation in the rack or cabinet, install the two
bottom screws first.
Caution Make sure that mounting the equipment does not create a hazardous condition due to uneven mechanical
loading. The equipment rack should be securely supported.
