Rack size and strength
Table 13 on page 31 provides the rack requirements and specifications for the
TCX1000-RDM20.
Table 13: Rack Requirements for the TCX1000-RDM20
Guidelines Rack Requirement
Use a two-post or four-post rack that provides bracket patterns spaced at 1-U (1.75 in. or 4.45 cm)
increments and that meets the size and strength requirements to support the weight.
A U is the standard rack unit defined in Cabinets, Racks, Panels, and Associated Equipment
(document number EIA-310–D) published by the Electronics Components Industry Association
(
http://www.ecianow.org/
).
Rack type: two-post or
four-post
The holes in the mounting brackets are spaced at 1.25 in. (or 3.17 cm), so that the TCX1000-RDM20
can be mounted in any rack that provides holes spaced at that distance. Mounting bracket hole
spacing
• Ensure that the rack complies with the standards for a 19-in., 21-in., or 23-in. rack as defined in
Cabinets, Racks, Panels, and Associated Equipment (document number EIA-310–D) published
by the Electronics Components Industry Association (
http://www.ecianow.org/
).
•
Ensure that the rack rails are spaced widely enough to accommodate the TCX1000-RDM20
chassis. The outer edges of the front-mounting brackets extend the width to 22.9 in. (58.16 cm).
• Ensure that the front and rear rack rails are spaced between 28 in. (71.1 cm) and 36 in. (91.4 cm)
front-to-back.
•
Ensure that the rack is strong enough to support the weight of the TCX1000-RDM20.
• Ensure that the spacing of rails and adjacent racks allows for proper clearance around the
TCX1000-RDM20 and rack.
Rack size and strength
• Secure the rack to the building structure.
•
If earthquakes are a possibility in your geographical area, secure the rack to the floor.
• Secure the rack to the ceiling brackets as well as to the wall or floor brackets for maximum
stability.
