Cabinet Requirements

If you are providing your own cabinet for an Express5800/320Fc, make sure the
cabinet contains a rack that is 19-in. wide and that meets the Electronic
Industries Association (EIA) 310-D standard.
Make sure that:
•
The cabinet contains two front and two rear vertical EIA rails, one in each corner of
the cabinet, that have the EIA universal square-hole pattern as defined in the EIA
310-D specification.
•
The front vertical rails extend at least 0.5 in. (1.27 cm) beyond the inside edge of
the accessory leg, if present, to allow the mounting rails to be fitted. See
•
The distance between the front and rear vertical rails is between 24.5 in. and 30 in.
(62.23 cm and 76.20 cm).
•
The vertical mounting rails accept 10-32 cage nuts and mounting hardware.
•
The distance between the front vertical rails and the inside of the front door is at
least 3.0 in. (7.62 cm).
•
The distance between the rear of the system chassis and the inside of the rear door
is at least 6.0 in. (15.24 cm).
•
The vertical mounting rails are plated or some other method is used to ensure
continuity for grounding between installed equipment.
•
Cable management brackets are provided to support and constrain data and power
cords so that the cables do not interfere with air flow out of the rear of the
enclosures, and so that the connectors do not disconnect or break.
•
The cabinet provides enough stability so that system components pass Telcordia
GR-63-CORE Section 5.4.2 regulations for operational vibration.
