or more CoreBuilder 9400 systems in a distribution

rack

■

Building and Electrical Codes

General Safety Requirements

For safe operation, your site must meet these general

safety requirements:

■

Environmental requirements. See Appendix A and

“Wiring Closet Recommendations” for details. Pay

special attention to temperature and humidity.

■

All building and electrical codes for your city and

country. See relevant “Building and Electrical

Codes” for more information.

■

Grounding requirements. See “Wiring Closet

Recommendations” and “Distribution Rack

Requirements” for details.

Wiring Closet Recommendations

The cabling system plan at your facility probably

covers most wiring closet concerns. 3Com also

recommends that you check these items:

■

Verify that your wiring closet meets all of the

requirements in your facility cabling plan.

■

Verify that your wiring closet and your facility meet

all state, local, and country building and wiring

codes.

■

Be sure that your system is easily accessible for

installation and service.

■

Provide

adequate overhead lighting for easy

maintenance.

■

Be sure that all wiring closet doors have locks to

prevent unauthorized access.

■

Assign wiring closet identification numbers using

architectural location codes or some type of

floor-grid matrix.

■

Select a vinyl floor covering for your wiring closet.

Concrete floors accumulate dust; carpets can

cause static electricity.

■

Be sure that the wiring closet floor is flat and level.

If you are using distribution racks and the floor is

not level, bolt the racks to the floor to prevent

them from tipping over.
