AC Power Cord Requirements
AC power input cords are not included with BlackDiamond X series power supplies. You can purchase
AC power cords for use in the US and Canada from Extreme Networks or 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 Selecting Power Supply Cords on page 106.
Warning
A dedicated Listed circuit breaker rated at 20A is to be used for each power supply
connection.
Un disjoncteurListed dédié évalué à 20A doit être utilisée pour chaque connexion
d'alimentation.
Uninterruptible 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.
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:
•
Automatically shut down equipment during long power outages.
•
Monitor and log 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.
