Rack Mounting Installation
1. Attach enclosed bracket ears to rack as shown in illustration.
2. Follow safety and installation considerations when placing the Digi
Passport unit on the rack.
Rack Mounting Safety and Installation Considerations
• Physical location and spacing
• Install equipment in Restricted Access Areas only (dedicated
equipment rooms/closets) in accordance with Articles 110-16,
110-17, and 110-18 of the National Electrical Code, ANSI/NFPA 70.
• To ensure proper ventilation and air flow for units, provide at least 12
inches (30 centimeters) of clearance on all sides for each unit.
• Distribute weight evenly in the rack to avoid overloading.
• Temperature
• Elevated operating ambient temperature: If installed in a closed or
multi-unit rack assembly, the operating ambient temperature of the
rack environment may be greater than room ambient temperature.
Install rack-mounted equipment in an environment compatible with
the manufacturer’s maximum rated ambient temperature (Tmra).
• For a rack setup with forced air, the device can run 0-55° C with no
extra space above or below the device (default design of the Digi
Passport Rack provides 1/16” = 2mm between devices).
• For a rack setup with no forced air, make sure the air in-between
devices does not get warmer than 55°C by providing space between
the devices, controlling the ambient temperature on the rack,
distributing weight evenly in the rack to avoid overloading, checking
equipment nameplate ratings before connecting to the supply circuit,
and maintaining reliable earthing of the rack-mounted equipment.
Rack shown in illustration is not
included with the Digi Passport
unit.
