Site Preparation
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.
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?
