The outer edges of the mounting brackets extend the width to 19 in. (48.3 cm). The front
cable management system adds 3.8 in. (9.7 cm) to the depth. If the front door is used,
this adds 5.5 in. (14 cm) to the depth of the chassis. The rear cable management system
adds 5.5 in. (14 cm) to the depth of the chassis.
The spacing of rails and adjacent racks must also allow for the clearances around the
chassis and rack that are specified in
Hardware Maintenance" on page
For instructions about installing the mounting hardware, see
Mounting Hardware for a Four-Post Rack or Cabinet" on page
The chassis height of 62.5 in. (158.8 cm) high is approximately 35.7 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 install one chassis
in a rack that has at least 35.7 U of usable vertical space.
The rack must be strong enough to support the weight of the fully configured PTX5000,
up to about 1200 lb (544.3 kg).
NOTE: In an open-frame rack, center-mounting is required because the more
even distribution of weight provides greater stability. For center-mounting,
you use the mounting brackets attached to the center of the chassis for rack
mounting.
