Item or Task
If a rack is used, secure rack to floor and building
structure.
Cables
Acquire cables and connectors:
Determine the number of cables needed
based on your planned configuration.
Review the maximum distance allowed for
each cable. Choose the length of cable based
on the distance between the hardware
components being connected.
Plan the cable routing and management.

The router can be installed in many types of racks, including four-post (telco) racks and
open-frame racks. An example of an open-frame rack is shown in Figure 48 on page 77.
For open-frame racks, center-mounting is preferable to front-mounting because the
more even distribution of weight provides greater stability.
The router is designed for installation in a 19-in. rack as defined in Cabinets, Racks, Panels,
and Associated Equipment (document number EIA-310-D) published by the Electronics
Industry Association (

With the use of adapters, the router can fit into a 600-mm-wide rack, as defined in the
four-part Equipment Engineering (EE); European Telecommunications Standard for
Equipment Practice (document numbers ETS 300 119-1 through 119-4) published by the
European Telecommunications Standards Institute (
wing devices to narrow the opening between the rails.
The rack rails must be spaced widely enough to accommodate the router chassis's
external dimensions: 37.45 in. (95.1 cm) high, 31 in. (78.7 cm) deep, and 17.43 in. (44.3 cm)
wide, excluding the front and rear cable management systems. The outer edges of the
mounting brackets extend the width to 19 in. (48.3 cm). The spacing of rails and adjacent
racks must also allow for the clearances around the router and rack.
The mounting holes for connecting the mounting brackets to the chassis are spaced
0.984 in. (25 mm) apart.
The chassis height of 37.45 in. (95.1 cm) is approximately 21.4 U. A
unit defined in Cabinets, Racks, Panels, and Associated Equipment (document number
EIA-310-D) published by the Electronics Industry Association. You can stack two routers
in a rack that has at least 42.8 U (74.9 in. or 1.90 m) of usable vertical space.
