Site Preparation

NOTE

For power specifications for Extreme Networks products, see the Extreme Networks website at

http://www.extremenetworks.com.

• When connecting power to installed equipment, avoid connecting through an extension cord or

power strip.

• If your switch includes more than one power supply, connect each power supply to different,

independent power sources. If a power source fails, it will only affect the switch power supply to

which it is connected. If all switch power supplies are connected to a single power source, the entire

switch is vulnerable to a power source failure.

AC Power Cable Requirements

Use an AC power cable appropriate for your country. Check your local electrical codes and regulatory

agencies for power cable requirements. The countries listed in Table 8 have the following additional

requirements.

NOTE

When using dual power supplies, make sure that each AC power supply attaches to an independent

power source.

Replacing the Power Cable

If the power cable plug is unsuitable and must be replaced, connect the power supply wires for the

switch according to the following scheme:

• Brown wire to the Live (Line) plug terminal, which may be marked with the letter “L” or colored

red.

• Blue wire to the Neutral plug terminal, which may be marked with the letter “N” or colored black.

• Yellow/Green wire to the Ground plug terminal, which may be marked with the letter “E” (the

Earth symbol) or colored yellow/green.
