Physical Characteristics

Be familiar with the physical characteristics of the Cisco ISR 4451-X to assist you in placing the system in the proper location.

Table 2-2shows the weight and dimensions of the Cisco ISR 4451-X.

Cisco ISR 4451-Xs

3.5in. (8.89 cm.)—2RU rack-mount

17.25in. (43.815 cm.)—19-inch rack-mount

18.7 in. (47.498 cm.)

(including card handles, cable-management brackets, power supply handles)

38-40 lbs (17.23-18.14 kg)

The following list describes additional Cisco ISR 4451-X chassis characteristics:

Chassis height meets EIA-310 rack spacing 2RU (3.5 inches/88.90 mm.), universal rack-mount

Chassis width meets EIA-310 19-inch (17.25 inches/438.15 mm) wide with rack brackets

Cable-management brackets at each Cisco ISR 4451-X locations can hold 16 ports of STP/UTP RJ 45 cables

Cable-management brackets allow a bend radius of 1.5 inches for cables

Adjustable rack-mount brackets allow for a front to rear rail variance distance of 15.50/394mm to 19.00/482.6mm

Rack Requirements

Some Cisco routers include brackets for use with a 19-inch rack or, if specified in your order, optional larger brackets for use with a 23-inch rack.

The following information can help you plan your equipment rack configuration:

Allow clearance around the rack for maintenance.

Allow at least one rack unit of vertical space between routers.

Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above it.

When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated in the rack.
