See
“Rack Requirements for the T4000 Router” on page 58
.
8.
Plan the location of the rack, including required space for airflow and maintenance.
See
“T4000 Clearance Requirements for Airflow and Hardware Maintenance” on
page 59
.
9.
Plan to secure the rack to the floor and building structure.
See
“Rack Requirements for the T4000 Router” on page 58
.
10.
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.
See the
T4000 Interface Module Reference
.
11.
Plan the cable routing and management.
See
“Maintaining T4000 PICs” on page 184

Rack Requirements for the T4000 Router
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 30 on page 59
.
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 (
http://www.etsi.org
). Use approved
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.
