JRR200 Rack and Cabinet Requirements

JRR200 Route Reflector Rack Requirements

The JRR200 Route Reflector is designed to be installed on four-post racks. Table 1 provides the rack requirements and specifications for the route reflector.

Table 1: Rack Requirements

Rack Requirement

Guidelines

Rack type

Use a 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 (http://www.eia.org).

Mounting bracket hole spacing

The holes in the mounting brackets are spaced at 1 U (1.75 in. or 4.45 cm), so that the device can be mounted in any rack that provides holes spaced at that distance.

Rack size and strength

  • Ensure that the rack complies with the size and strength standards of a 19-in. 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).

  • The rack must be strong enough to support the weight of the JRR200 route reflector.

  • Ensure that the spacing of rails and adjacent racks provides for proper clearance around the JRR200 route reflector and rack.

Rack connection to building structure

  • 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 for maximum stability.

JRR200 Route Reflector Cabinet Requirements

You can install the JRR200 Route Reflector in a 19 in. (48.7 cm) cabinet. Table 2 provides the cabinet requirements and specifications.

Table 2: Cabinet Requirements and Specifications

Cabinet Requirement

Guideline

Cabinet size

You can mount the JRR200 route reflector in a cabinet that contains a 19-in. rack as defined in Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published by the Electronics Industry Association (http://www.ecianow.org/standards-practices/standards/).

Cabinet clearance

  • The outer edges of the mounting brackets extend the width of the chassis to 19 in. (48.2 cm).

  • The minimum total clearance inside the cabinet is 30 in. (76.2 cm) between the inside of the front door and the inside of the rear door.

Cabinet airflow requirements

When you mount JRR200 route reflector in a cabinet, you must ensure that ventilation through the cabinet is sufficient to prevent overheating.

  • Install the JRR200 route reflector as close as possible to the front of the cabinet so that the cable management system clears the inside of the front door. Installing the chassis close to the front of the cabinet maximizes the clearance in the rear of the cabinet for critical airflow.

  • Ensure adequate cool air supply to dissipate the thermal output of the JRR200 route reflector.

  • Route and dress all cables to minimize the blockage of airflow to and from the chassis.

  • A cabinet larger than the minimum required provides better airflow and reduces the chance of overheating.
