Table 18: Rack Requirements for the Services Gateway

Specifications

Rack Requirement

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

).

Size

The outer edges of the mounting brackets extend the width of either
chassis to 19 in. (48.3 cm).

The front of the chassis extends approximately 0.5 in. (1.27 cm) beyond
the mounting ears.

Maximum permissible ambient temperature when two devices are
placed side by side in a 19 in. rack is 40° C.

Clearance

The holes within each rack set are spaced at 1 U [1.75 in. (4.5 cm)]. The
device can be mounted in any rack that provides holes or hole patterns
spaced at 1-U [1.75 in. (4.5 cm)] increments.

The mounting brackets and front-mount flanges used to attach the
chassis to a rack are designed to fasten to holes spaced at rack
distances of 1 U (1.75 in.).

The mounting holes in the mounting brackets provided with the device
are spaced 1.25 in. (3.2 cm) apart (top and bottom mounting hole).

Spacing of Mounting
Bracket and Flange
Holes

Always secure the rack in which you are installing the services gateway
to the structure of the building. If your geographical area is subject to
earthquakes, bolt the rack to the floor. For maximum stability, also secure
the rack to ceiling brackets.

Clearance Requirements for Airflow and Hardware Maintenance of the SRX210 Services
Gateway

When planning the installation site for the SRX210 Services Gateway, you need to allow
sufficient clearance around the rack or cabinet where you are planning to install the
device.

When planning the installation site for the services gateway, consider the following:

For the cooling system to function properly, the airflow around the chassis must be
unrestricted.

For service personnel to remove and install hardware components, there must be
adequate space at the front and back of the device. Allow at least 24 in. (61 cm) both
in front of and behind the device.
