An AC-powered MGX 8830 or MGX 8830/B switch dissipates up to 4800 BTUs (1.4 kW) per hour, and
a DC-powered MGX 8830 or MGX 8830/B switch dissipates up to 4100 BTUs (1.2 kW) per hour.
Warning To prevent the system from overheating, do not operate it in an area that exceeds the maximum
recommended ambient temperature of 104°F (40°C). Statement 1047
Electrical equipment generates heat. Ambient air temperature might not be able to cool equipment to
Note
acceptable operating temperatures without adequate circulation. Ensure that the room in which you
operate your system has adequate air circulation.
Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested, because
each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air.
The enclosure must also provide adequate cooling through the use of an appropriately sized heat
exchanger or air conditioner, which dissipates the heat generated by existing remote terminal system
components and by the installed switch.
Ventilation
The fan tray, located inside the card cage, pulls ambient cooling air into the system through openings
between the front card faceplates, over the boards in the switch, and out through the air exhaust openings
on the left side of the switch.
The fan tray houses eight fans that provide system cooling. The MGX 8830 or MGX 8830/B switch
requires that a fan tray be installed when the system is in operation.
Note There must be at least two inches of empty space around the front and rear panels of the AC power supply
for cooling air.
Electrical equipment generates heat. Ambient air temperature might not be able to cool equipment to
acceptable operating temperatures without adequate circulation. Ensure that the room in which you
operate your system has adequate air circulation.
