effectively.
The topics covered in this appendix:

■ Building and Electrical Codes
General Safety Requirements
For safe operation, your site must meet these general
safety requirements:
■ All environmental requirements listed in Appendix
A and in “Wiring Closet Recommendations.” 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.
■ All grounding requirements listed in “Wiring
Closet Recommendations” and “Distribution Rack
Requirements.”
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.
