SRX3400 Services Gateway Rack Size and Strength Requirements
The services gateway is designed for installation into a 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.eia.org ).
With the use of adapters, the services gateway is designed to fit into a 600-mm-wide
rack or cabinet, as defined in the four-part
Equipment Engineering (EE); European
telecommunications standard for equipment practice (document numbers ETS 300 119-1
through 119-4) published by the European Telecommunications Standards Institute
(
http://www.etsi.org
). Use approved wing devices to narrow the opening between the
rails.
The rack rails must be spaced widely enough to accommodate the services gateway
chassis's external dimensions: 5.25 in. (13.3 cm) high, 25.5 in. (64.8 cm) deep, and
17.5 in. (44.5 cm) wide. The spacing of rails and adjacent racks must also allow for the
clearances around the services gateway and rack.
The chassis height of 5.25 in. (13.3 cm) is approximately 3 U. 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. You can stack eight
SRX3400 Services Gateways in a rack that has at least 40 U (70 in. or 1.78 m) of usable
vertical space.
The rack must be strong enough to support the weight of the fully configured services
gateway, up to 77 lb (35 kg). If you stack eight fully configured services gateways in one
rack, it must be capable of supporting up to 616 lb (280 kg).
