Review the maximum distance allowed for each cable. Choose the length of cable
based on the distance between the hardware components being connected.

Overview of Installing the T4000 Router on page 55
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
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 (
http://www.eia.org
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.
