Thermal Recom-
mendations
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.
General
Recommendations
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.

Wiring Closet
Considerations
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.
