Table 25: Rack Requirements for the PTX10001-36MR
Rack
Requirement
Guidelines
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 paerns 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 dened in Cabinets, Racks, Panels, and Associated Equipment
(document number EIA-310–D) published by the Electronics Components Industry
Associaon (hp://www.ecianow.org/).
Mounng bracket
hole spacing
The holes in the mounng brackets are spaced at 1-U (1.75 in. or 4.45 cm) increments, so
that the PTX10001-36MR can be mounted in any rack that provides holes spaced at that
distance.
Rack size and
strength
• Ensure that the rack complies with the standards for a 19-in. rack as dened in Cabinets,
Racks, Panels, and Associated Equipment (document number EIA-310–D) published by
the Electronics Components Industry Associaon (hp://www.ecianow.org/).
• Use a 600-mm rack as dened in the four-part Equipment Engineering (EE); European
telecommunicaons standard for equipment pracce (document numbers ETS 300
119-1 through 119-4) published by the European Telecommunicaons Standards
Instute (hp://www.etsi.org).
The horizontal spacing between the rails in a rack that complies with this standard is
usually wider than the router’s mounng 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 mounng
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.
