Table 25: Rack Requirements for the PTX10001-36MR
Rack
Guidelines
Requirement
Rack type
Use a two-post or a four-post rack. You can mount the device on any two-post or four-post
rack that provides bracket holes or hole 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
(document number EIA-310–D) published by the Electronics Components Industry
Association
Mounting bracket
The holes in the mounting brackets are spaced at 1-U (1.75 in. or 4.45 cm) increments, so
hole spacing
that the PTX10001-36MR can be mounted in any rack that provides holes spaced at that
distance.
Rack size and
•
Ensure that the rack complies with the standards for a 19-in. rack as defined in
strength
Racks, Panels, and Associated Equipment (document number EIA-310–D) published by
the Electronics Components Industry Association
•
Use a 600-mm rack as defined in the four-part
telecommunications standard for equipment practice (document numbers ETS 300
119-1 through 119-4) published by the European Telecommunications Standards
Institute
The horizontal spacing between the rails in a rack that complies with this standard is
usually wider than the router's mounting brackets, which measure 19 in. (48.26 cm) from
outer edge to outer edge. Use approved wing devices to narrow the opening between
the rails as required.
•
Ensure that the rack rails are spaced widely enough to accommodate the
PTX10001-36MR chassis' external dimensions. The outer edges of the front mounting
rails extend the width to 19 in. (48.26 cm).
•
Ensure that the front and rear rack rails are spaced between 23.6 in. (60 cm) and 31.5 in.
(80 cm) front-to-back.
•
Ensure that the rack is strong enough to support the weight of the device.
•
Ensure that the spacing of rails and adjacent racks allows for proper clearance around the
PTX10001-36MR and rack.
