Rack-Mounting Requirements - Juniper SRX5400 Getting Started Manual

Rack-Mounting Requirements

You can install the services gateway in a four-post rack or cabinet or an open-frame rack.
The rack rails must be spaced widely enough to accommodate the services gateway chassis' external
dimensions: 8.71 in. (22.1 cm) high, 24.5 in. (62.2 cm) deep, and 17.45 in. (44.3 cm) wide. The mounting
brackets extend the width to 19 in. (48.3 cm). See
Figure 1: Rack Clearance and Chassis Dimensions
The rack must be strong enough to support the weight of the fully configured services gateway, up to
128 lb (58.1 kg).
For the cooling system to function properly, the airflow around the chassis must be unrestricted. Allow
at least 6 in. (15.2 cm) of clearance between side-cooled services gateways. Allow 2.8 in. (7 cm) between
the side of the chassis and any non-heat-producing surface such as a wall.
For service personnel to remove and install hardware components, there must be adequate space at the
front and back of the services gateway. Allow at least 30 in. (76.2 cm) in front of the services gateway
and 24 in. (61 cm) behind the services gateway.
The rack or cabinet must have an adequate supply of cooling air.
