Table 19: Rack Requirements for the Services Gateway

Rack Requirement Specifications
Size 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 (
Clearance 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.
Spacing of Mounting The holes within each rack set are spaced at 1 U [1.75 in. (4.5 cm)]. The
Bracket and Flange device can be mounted in any rack that provides holes or hole patterns
Holes 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).
Connecting to the Always secure the rack in which you are installing the services gateway
Building Structure 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.

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.
If you are mounting the device in a rack with other equipment, or if you are placing it
on the desktop near other equipment, ensure that the exhaust from other equipment
does not blow into the intake vents of the chassis.
