Site Preparation
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.
Uninterruptable Power Supply Requirements
An uninterruptible power supply (UPS) is a device that sits between a power supply (such as a wall
outlet) and a device (such as a switch) to prevent outages, sags, surges, and bad harmonics from
adversely affecting the performance of the device.
UPS Features
A UPS traditionally can perform the following functions:
•
Absorb relatively small power surges.
•
Smooth out noisy power sources.
•
Continue to provide power to equipment during line sags.
•
Provide power for some time after a blackout has occurred.
In addition, some UPS or UPS plus software combinations provide the following functions:
•
Automatic shutdown of equipment during long power outages.
•
Monitoring and logging of power supply status.
•
Display the voltage (current draw) of the equipment.
•
Restart equipment after a long power outage.
•
Display the voltage currently on the line.
•
Provide alarms on certain error conditions.
•
Provide short circuit protection.
Selecting a UPS
To determine UPS requirements for your switch, ask these questions:
•
What are the amperage requirements?
•
What is the longest potential time period that the UPS would be required to supply backup power?
•
Where will the UPS be installed?
•
What is the maximum transition time that your installation will allow?
NOTE
Extreme Networks recommends that you use a UPS that provides online protection.
