3-2 MAX TNT Hardware Installation Gulide
Installing a MAX TNT Chassis
Rack-mounting a MAX TNT unit
• Racks with open sides are recommended because the MAX TNT fans vent on the side of
the unit.
• Ensure adequate cooling in the room.
– The maximum recommended ambient temperature for MAX TNT models is 104°
Fahrenheit (40° Celsius). Take care to allow sufficient air circulation or space
between units when a MAX TNT unit is installed in a closed or multirack assembly,
because the operating ambient temperature of the rack environment might be greater
than room ambient temperatures.
– In enclosed racks, make sure that openings exist in the floor underneath each cabinet
to allow the air conditioning up into the cabinet.
– Exhaust fans at the top of the cabinet are recommended but not required. At a
minimum, the cabinets must be ventilated at the top.
Rack-mounting a MAX TNT unit
Before installing the unit in a rack, you must install the rack ears as illustrated in Figure 3-1.
Rack ears are normally shipped with your unit. If you did not receive them, contact your
Lucent reseller. Apply 7 to 8 inch-pounds (0.8 to 0.9 joules) of torque to each screw.
