Cisco ONS 15454, Hardware Installation Manual

Page: 209 / 516

Mounting a Single Node
Mounting the ONS 15454 M2 shelf on a rack requires a minimum of 3.5 inches (88.9 mm) of vertical rack
space. To ensure the mounting is secure, use two to three #12-24 mounting screws for each side of the shelf.
For an ANSI rack, the brackets can be mounted in the front or middle position. The shelf should be empty
for easier lifting. For information on the ONS 15454 M2 shelf weight, refer to the
Dimensions , on page 474 .
The ONS 15454 M2 shelves can be mounted above each other without any space between the shelves. This
method of mounting does not restrict the air flow because the air vents are on either sides of the ONS 15454
M2 shelves.
ETSI Rack Installation
The ONS 15454 M2 shelf is mounted on a 600 x 600-mm (23.6 x 23.6-inch) or 600 x 300-mm (23.6 x
11.8-inch) ETSI standard equipment rack. In an ETSI rack, the shelf can be mounted only in the front position.
The shelf projects 1.7 inches from the front of the rack. The shelf is a total of 17.2 inches (431.8 mm) wide
with no mounting ears attached. Cisco does not provide ring runs, which might hinder side-by-side installation
of shelves where space is limited.
The ONS 15454 M2 shelf measures 88.9 mm (3.5 inches) high, 535 mm (21.06 inches) wide, and 11.1 inches
(304.8 mm) deep.
The following figure provides the dimensions of the ONS 15454 M2 shelf installed on a 600 x 600-mm (23.6
x 23.6-inch) ETSI standard equipment rack.
When mounting a shelf in a partially filled rack, load the rack from the bottom to the top with the heaviest
component at the bottom of the rack. If the rack is provided with stabilizing devices, install the stabilizers
before mounting or servicing the unit in the rack. Caution
