Rack Requirements for a CTP151 Device

You can mount the CTP151 device 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 1 provides the rack requirements and specifications for the device.

Rack Requirement

Guidelines

Rack type

Use a two-post rack or a four-post rack. You can mount the device 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.ecianow.org/standards-practices/standards/).

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 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 standard defined for 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/).

  • Ensure that the rack rails are spaced widely enough to accommodate the device chassis' external dimensions of 1.72 in. (4.3 cm) height, 17.36 in. (44.1 cm) width, and 12 in. (30.5 cm) depth. The 19-in. rack brackets dimensions are 0.82 in. (2.1 cm) wide, 1.72 in. (4.3 cm) height, and 2.1 in. (5.4 cm) depth. The 23-in. rack brackets dimensions are 3.3 in. (8.4 cm) wide, 1.72 in. (4.3 cm) height, and 8.5 in. (21.6 cm) depth.

  • The rack must be strong enough to support the weight of the device.

  • Ensure that the spacing of rails and adjacent racks allows for the proper clearance around the device 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 wall or floor brackets for maximum stability.

One pair of mounting brackets for mounting the device on two posts of a rack is supplied with each device. For mounting the device on four posts of a rack or cabinet, you can use the supplied two-post rack-mounting kit and secure the device to two of the posts.
