MX5, MX10, MX40, and MX80 Rack Requirements
The router can be installed in a rack. Many types of racks are acceptable, including
four-post (telco) racks and open-frame racks. An exampleof an open-frame rack appears
in Figure 26 on page 47. Table 21 on page 46 summarizes rack requirements and
specifications for the MX5, MX10, MX40, and MX80 router.
Table 21: MX5, MX10, MX40, and MX80 Rack Requirements and Specifications
GuidelinesRack Requirement
Use a four-post rack or a two-post rack. You can mount the router on any four-post
or two-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 (http://www.ecianow.org/).
Rack type and mounting bracket hole
spacing
•
Ensure that the rack is a 19-in. rack as defined in Cabinets, Racks, Panels, and
Associated Equipment (documentnumber EIA-310–D) published by the Electronics
Components Industry Association (http://www.ecianow.org/).
•
Ensure that the rack is one of the following standard lengths:
•
23.62 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: 3.5 in. (8.9 cm) high, 23.46 in. (59.6 cm) deep, and
17.5 in. (44.5 cm) wide. The outer edges of the mounting brackets extend the width
to 19.2 in. (48.7 cm). The spacing of rails and adjacent racks must also allow for the
clearances around the router and rack that are specified in “MX5, MX10, MX40, and
MX80 Routers Clearance Requirements for Airflow and Hardware Maintenance”
on page 47.
•
The router ships with the mounting brackets installed in the front-mount position.
You can also move the brackets to the center-mount position. For instructions about
moving the mounting hardware, see “Moving the Mounting Brackets for
Center-Mounting MX5, MX10, MX40, and MX80 Routers” on page 80.
•
The chassis height of 3.5 in. (8.9 cm) is approximately 2 U.
•
The rack must be strong enough to support the weight of the fully configured router,
up to 30 lb (13.6 kg).
•
Ensure that the spacing of rails and adjacent racks allows for the proper clearance
around the router and rack as specified in “MX5, MX10, MX40, and MX80 Routers
Clearance Requirements for Airflow and Hardware Maintenance” on page 47.
Rack size and strength
•
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.
