Where:
The 2.0-meter Rack Trim Kit (#6272) is used if no front door is used in the rack.
The Front Door for a 2.0-meter Rack (#6069) is made of steel with a perforated flat front
surface. The perforation pattern extends from the bottom to the top of the door to enhance
ventilation and provide visibility into the rack. This door is non-acoustic and has a depth of
about 25 mm (1 in.).
The 2.0-meter Rack Acoustic Door (#6249) consists of a front and rear door to reduce
noise by approximately 6 dB(A). It has a depth of approximately 191 mm (7.5 in.).
The #ERG7 provides an attractive black full height rack door. The door is steel with a
perforated flat front surface. The perforation pattern extends from the bottom to the top of
the door to enhance ventilation and provide visibility into the rack. The non-acoustic door
has a depth of about 134 mm (5.3 in.).
Rear Door Heat Exchanger
To lead away more heat, a special door that is named the Rear Door Heat Exchanger
(#EC15) is available. This door replaces the standard rear door on the rack. Copper tubes
that are attached to the rear door circulate chilled water, which is provided by the client. The
chilled water removes heat from the exhaust air being blown through the servers and
attachments that are mounted in the rack. With industry-standard quick couplings, the water
lines in the door attach to the client-supplied secondary water loop.
