Rack Mounting Installation Considerations (PortServer TS 16 Rack and DC Rack
and PortServer TS 16 48V Dual Feed)
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 PortServer Rack
provides 1/16” = 2mm between devices).
For a rack setup with no forced air, make sure that the air in-between
devices does not get warmer than 55°C by the following measures:
• Providing space between the devices, or
• Controlling the ambient temperature on the rack.
Additional installation precautions for the PortServer TS Rack and DC
Rack include:
• Distribute weight evenly in the rack to avoid overloading.
• Check equipment nameplate ratings before connecting to the supply
circuit to avoid overloads which may damage over-current protection
devices and supply wiring.
• Maintain reliable earthing for rack-mounting equipment, especially
for supply connections.
