This sections contains recommendations for handling the heat generated
by the CoreBuilder 7000 family ATM switch. It is essential that you
provide a suitable environment for both performance and safety.
The following are some general thermal recommendations for the wiring
closet:
Ensure that the ventilation in the wiring closet is adequate to maintain
a temperature below 40° C (104° F).
During non-business hours, make sure that the ventilation is not shut
down while a CoreBuilder 7000 family ATM switch remains powered
up; otherwise, the equipment may overheat.
The following are power and heat specifications for the CoreBuilder 7000
family ATM switch:
Maximum power consumption: 250 Watts
Maximum heat generated: 1724 BTU per hour
Operating temperature: 0° to 40° C (32° to 104° F)
The cabling system used at the facility should cover the majority of wiring
closet concerns. You may want to consider the following
recommendations.
Verify that the facility meets all requirements mentioned in the system
cabling plan.
Ensure that the system is easily accessible for installation and service.
Use AC power, 15-Amp service receptacles, type N5/15 or NEMA
5-15R for 120Vac.
Select a vinyl floor covering for the wiring closet. (Concrete floors tend
to accumulate dust, and carpets often cause static electricity.)
Ensure that the wiring closet floor is flat and level. If the floor is not
level, ensure that the racks are bolted to the floor to prevent them
from tipping over.
