ACX500 Mounting Requirements

 

Cabinet Requirements for ACX500 Indoor Routers

You can mount the indoor router in a cabinet that contains a 19-in. (48.3 cm) rack.

Cabinet requirements consist of:

  • Cabinet size

  • Clearance requirements

  • Cabinet airflow requirements

Table 1 provides the cabinet requirements and specifications for the router.

Table 1: Cabinet Requirements and Specifications for the ACX500 Indoor Router

Cabinet Requirement

Guidelines

Cabinet size

  • You can mount the router in a cabinet that contains 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).

    Note: The cabinet must meet the strength requirements to support the weight of the router.

  • The minimum cabinet size must be able to accommodate the maximum external dimensions of the router.

Cabinet clearance

  • The outer edges of the mounting brackets extend the width of the chassis to 19 in. (48.3 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 the router in a cabinet, ensure that ventilation through the cabinet is sufficient to prevent overheating.

  • Ensure an adequate cool air supply to dissipate the thermal output of the router or routers.

  • When deploying the router in harsh environments, allow a 1–rack unit (U) gap above and below the router.

  • Minimum 1 meter/second airflow in any direction

  • Ensure that the cabinet allows the hot exhaust air from the chassis to exit the cabinet without recirculating into the router. An open cabinet (without a top or doors) that employs hot air exhaust extraction from the top allows the best airflow through the chassis. If the cabinet contains a top or doors, perforations in these elements assist with removing the hot air exhaust.

  • Install the router in the cabinet in a way that maximizes the open space on the side of the chassis that has the hot air exhaust. This space maximizes the clearance for critical airflow.

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

  • Ensure that the spacing of rails and adjacent cabinets allows for the proper clearance around the router and cabinet.

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

Wall Requirements for ACX500 Outdoor Routers

Note

The information provided in this topic is applicable for both the ACX500 outdoor router variants—ACX500 outdoor router and ACX500 outdoor router with PoE.

You can install the ACX500 outdoor router on a wall. When choosing a location, allow at least 6 in. (15.2 cm) of clearance between the sides of the chassis (with the router in installed position) and adjacent equipment or walls. Ensure that the wall onto which the router is installed is stable and securely supported. If you are mounting the router in sheetrock (wall board with a gypsum plaster core) or in wall board not backed by wall studs, use hollow wall anchors capable of supporting the combined weight of two fully loaded chassis. Insert the screws into wall studs wherever possible to provide added support for the chassis.

Use the wall-mounting kit from Juniper Networks to mount the router on a wall. The wall-mounting kit is not part of the standard package and needs to be ordered separately.

Pole Requirements for ACX500 Outdoor Routers

Note

The information provided in this topic is applicable for both the ACX500 outdoor router variants—ACX500 outdoor router and ACX500 outdoor router with PoE.

You can install the ACX500 outdoor router on a pole. When choosing a location, allow at least 6 in. (15.2 cm) of clearance between the sides of the chassis (with the router in installed position) and adjacent equipment or walls. Ensure that the pole onto which the router is installed is stable and securely supported. Ensure that the pole should be able to carry the load of the fully configured router. The width of the pole must be within the range of 2  in. (5 cm) through 16 in. (40.6 cm) for the pole-mounting brackets to fit properly.

Use the pole-mounting kit from Juniper Networks to mount the router on a pole. The pole-mounting kit is not part of the standard package and needs to be ordered separately.

Rack Requirements for ACX500 Indoor Routers

You can mount the indoor router on two-post racks or four-post racks.

Rack requirements consist of:

  • Rack type

  • Mounting bracket hole spacing

  • Rack size and strength

  • Rack connection to the building structure

Table 2 provides the rack requirements and specifications for the router.

Table 2: Rack Requirements and Specifications for the ACX500 Indoor Router

Rack Requirement

Guidelines

Rack type

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

The rack must meet the strength requirements to support the weight of the chassis.

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 router can be mounted in any rack that provides holes spaced at that distance.

Rack size and strength

  • 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 router chassis' external dimensions. 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.

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 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 mounting kit separately.
