The MX204 router can be installed in a standard 19-in. rack. Many types of racks are
acceptable, including four-post (telco) racks and open-frame racks.
summarizes rack requirements and specifications for the router.
Guidelines
Use a four-post rack. You can mount the router on any four-post rack that provides
bracket holes or hole patterns spaced at 1 U (1.75-in./4.44-cm) increments and that
meets the size and strength requirements specified in this table.
A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated
Equipment (document number EIA-310–D) published by the Electronics Components
Industry Association (
Ensure that the rack is a 19-in. rack as defined in Cabinets, Racks, Panels, and
Associated Equipment (document number EIA-310–D) published by the Electronics
Components Industry Association (
Ensure that the rack is one of the following standard lengths:
23.6 in. (600 mm)
30.0 in. (762 mm)
31.5 in. (800 mm)
The rack rails must be spaced widely enough to accommodate the router chassis's
external dimensions (see
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 router ships with the front-mounting brackets fixed in the front-mount position
on the chassis. You can move the rear-mounting brackets based on the depth of
the rack.
The chassis height of 1.72 in. (4.37 cm) is approximately 1 U (rack unit).
The rack must be strong enough to support the weight of the fully configured router,
up to 22.7 lb (10.3 kg).
Either end of the router must be mounted flush with the rack and still be adjustable
for racks with different depths. The front and rear rack rails must be spaced between
23.62 in. (600 mm) and 31.5 in. (800 mm) front to back.
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 geographic area, secure the rack to the floor.
Secure the rack to the ceiling brackets as well as wall or floor brackets for maximum
stability.
