Wiring Closet Considerations

You should consider the following recommendations for your wiring closet:

• Ensure that your system is easily accessible for installation and service. See “Rack

Specifications and Recommendations” on page 2-12 for specific recommendations.

• Use AC power, 15-amp service receptacles, type N5/15 or NEMA 5-15R for 120 VAC.

• Use 30 A at -40 VDC (or equivalent power between -40 and -70 VDC) for Alpine DC

power supplies. For Alpine DC power and ground cables, use 8 AWG,

high-strand-count wire cable (Alpine 3808) or 10 AWG, high-strand-count wire cable

(Alpine 3804).

• Use AC power, 20 A service receptacle, NEMA L5-20R for BlackDiamond 110 VAC

power supplies.

• Use AC power, 20 A service receptacle, NEMA L6-20R for BlackDiamond 220 VAC

power supplies.

• Use 55 A service for BlackDiamond DC power supplies. For BlackDiamond DC

power cables, use 4 AWG, high-strand-count wire cable.

• Use a vinyl floor covering in your wiring closet. (Concrete floors accumulate dust,

and carpets can cause static electricity.)

• Prevent unauthorized access to wiring closets by providing door locks.

• Provide adequate overhead lighting for easy maintenance.

• Ensure that each wiring closet has a suitable ground. All distribution racks and

equipment installed in the closet should be grounded.

• Ensure that all system environmental requirements are met, such as ambient

temperature and humidity.

Note: Extreme Networks recommends that you consult an electrical contractor

for commercial building and wiring specifications.

Temperature. Extreme Networks equipment generates a significant amount of heat. It

is essential that you provide a temperature-controlled environment for both

performance and safety.

The following are some general thermal recommendations for your wiring closet:

• Ensure that the ventilation in the wiring closet is adequate to maintain a temperature

below 104° F (40° C).

• Install a reliable air conditioning and ventilation system.
