Cabinet Requirements for MX104 Routers

Guidelines
Use a two-post rack or a four-post rack. You can mount the router on any two-post or four-post
rack that provides bracket holes or hole patterns spaced at 1 U (1.75 in., or 4.45 cm) increments and
that meets the size and strength requirements to support the weight.
A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment (document
number EIA-310–D) published by the Electronics Industry Association (
The rack must meet the strength requirements to support the weight of the chassis.
The holes in the mounting brackets are spaced at 1 U (1.75 in., or 4.45 cm) so that the router can be
mounted in any rack that provides holes spaced at that distance.
Ensure that the rack complies with this standard:
A 19-in. (48.3 cm) 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 ).
Ensure that the rack rails are spaced widely enough to accommodate the external dimensions
of the router chassis. The outer edges of the front-mounting brackets extend the width of the
chassis to 19.2 in. (48.7 cm).
The rack must be strong enough to support the weight of the router.
Ensure that the spacing of rails and adjacent racks allows for the proper clearance around the
router and rack.
Secure the rack to the building structure.
If earthquakes are a possibility in your geographical area, secure the rack to the floor.
Secure the rack to the ceiling brackets as well as to the wall or floor brackets for maximum
stability.
One pair of mounting brackets for mounting the router on two posts of a rack is supplied
with each router. For mounting the router on four posts of a rack or cabinet, you can order
a four-post rack-mount kit separately.
