Cisco 7507 and Cisco 7507-MX Rack-Mount Considerations

An optional rack-mounting kit is available for mounting the Cisco 7507 or Cisco 7507-MX in a standard
19-inch (48.26 cm) equipment rack. The mounting kit is not suitable for use with 2-post equipment
racks, or those with obstructions (such as a power strip) that could impair access to the interface
processors and power supplies. In telco environments or at installation sites that use nonstandard racks,
the router can be mounted on an equipment shelf, provided that the rack dimensions allow safe
installation and access to the power supplies and interface processors.
footprint and outer dimensions.
To use the optional rack-mount kit, your equipment rack must meet the following requirements:

If you plan to use an equipment shelf, ensure that the shelf is constructed to support the weight and
dimensions of the chassis.
designing a customized shelf.
If you use 2-post racks, be sure that the rack is bolted to the floor and secured. One end of the chassis
mounts to the two rack posts with the chassis ears, and the rest of the chassis is cantilevered off the
posts. Ensure that the weight of the chassis does not make the rack unstable. Some 2-post racks are
also secured to ceiling brackets if warranted by the weight of the equipment in the rack.
2-15.
The width of the rack, between the two front mounting strips or rails, must be 17.75 inches (45.09
cm).
The depth of the rack, between the front and rear mounting strips, must be at least 19.25 inches
(48.90 cm) but not more than 32 inches (81.28 cm).
The height of the chassis is approximately 20 inches (50.08 cm) (19.25 inches [48.90 cm] when the
chassis feet are removed). The rack must have sufficient vertical clearance to insert the chassis and,
if required after installation, to remove the chassis feet.
If the rack has a vertical power strip or other potential obstacle, ensure that it will allow sufficient
clearance to install and remove both interface processors (11 inches [27.94 cm] deep) and power
supplies (16 inches [40.64 cm] deep), both of which must be pulled straight out of the chassis.
