Before you install the PTX10008, make sure the site meets all of the rack, power, cooling, and clearance requirements.
Rack-Mount Requirements
The PTX10008 router chassis is designed to be installed in standard 19-in. wide four-post racks that are spaced at 1 U
(1.75 in. or 4.45 cm) increments.
You can stack a maximum of three PTX10008 chassis in a four-post rack if:
The rack is 42 U or greater.
The rack meets the strength requirements to support the weight of the chassis and the cabling. A single PTX10008
chassis without optics and cabling can range from 145.2 lb (65.86 kg) to 421.25 lb (191.07 kg).
The facility has adequate cooling and power to support additional systems.
Power Requirements
The PTX10008 router is available in AC, DC, high voltage AC (HVAC) and high voltage DC (HVDC) power configurations.
Each configuration has different power supplies, power cables, and cooling requirements. The power configuration and
the number of line cards you are installing determine your power requirements for the system. A procedure to determine
these power requirements is available in the PTX10008 Packet Transport Hardware Guide.
