PoE Devices
When connecting power over Ethernet (PoE) devices to a PoE switch, all connections between the PoE
device and the switch must remain within the same building and use a low-voltage power distribution
system per IEEE 802.3af.
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 4 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.
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.
