Power Supply Requirements
Follow these recommendations when you plan power supply connections for your Extreme Networks
equipment:
•
Place the equipment in an area that accommodates the power consumption and component heat
dissipation specifications.
•
Be sure that your power supply meets the site DC power or AC power requirements of the network
equipment.
•
When you connect power to installed equipment, do not make this connection 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 affect only the 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.
•
In regions that are susceptible to electrical storms, Extreme Networks recommends that you plug
your system into a surge suppressor.
For power specifications of the BlackDiamond power supplies, see

Warning
The chassis does not have a switch for turning power to the unit on and off. For systems using
an AC power supply, power to the chassis is disconnected by removing the wall plug from the
electrical outlet. For systems using a DC SSI power supply, power to the chassis can be turned
off by lifting the handle on the power supply or by de-energizing the circuit that feeds the
power supply, which is usually accomplished by turning off a circuit breaker.
AC Power Cord Requirements
AC power input cords are not provided with BlackDiamond power supplies. To purchase a power cord
for your product and for your specific country, contact your local Extreme Networks Channel Account
Manager or Sales Manager, or purchase a cord from your local supplier.
Make sure that the power cord you use is certified for the country of end use and suitable for the device.
Check your local electrical codes and regulatory agencies for power cable requirements.
The power cord must meet the requirements listed in
Cable Routing for PoE Devices
on page 143.
Note
When using multiple power supplies, make sure that each AC power supply attaches to an
independent power source.
