The weight, height, and depth of the router depends on the type of cable manager
installed.
With the standard cable manager installed, use these guidelines:
The rack must have sufficient vertical usable space to accomodate the height of the
router: 27.75 in. (70.49 cm) high (approximately 16 U.),. You can stack three MX960
routers with the standard cable manager in a rack that has at least 48 U (89.3 in. or
2.24 m).
NOTE: A is the standard rack unit defined in Cabinets, Racks, Panels, and
U

The location of the rack must provide sufficient space to accomodate the depth of the
router. The chassis is 23.0 in. (58.42 cm) deep, but The standard cable manager extends
the depth to 28.0 in. (71.1 cm).
The rack must be strong enough to support the weight of the fully configured router,
up to 350 lb (158.76 kg). If you stack three fully configured routers, it must be capable
of supporting up to 1,050 lb (476.3 kg).
With the extended cable manager installed, use these guidelines:
The rack must have sufficient vertical usable space to accomodate the additional
height of the extended cable manager: 36.5 in. (92.7 cm) high (approximately 21 U).
You can stack two MX960 routers in a rack that has at least 48 U (89.3 in. or 2.24 m).
The rack must be able to accomodate the additional depth of the extended cable
manager. The chassis with the extended cable manager installed is29.00 in. (73.7 cm)
deep.
The rack must be strong enough to support up to 374 lb (169.64 kg). If you stack two
fully configured routers, it must be capable of supporting up to 748 lb (339.28 kg).
The holes within each set are spaced at 1 U (1.75 in. or 4.5 cm). The router can be mounted
in any rack that provides holes spaced at those distances.
The router can be mounted in any rack that provides holes or hole patterns spaced at 1U
(1.75 in.) increments. The mounting brackets and front-mount flanges used to attach
the chassis to a rack are designed to fasten to holes spaced at those distances.
