provide a suitable environment for both performance and safety.

General

The following are some general thermal recommendations for the wiring

Recommendations

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.

Power and Heat

The following are power and heat specifications for the CoreBuilder 7000

Specifications

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)

 

 

Wiring Closet

The cabling system used at the facility should cover the majority of wiring

Considerations

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.
