Power Supply Installation
2.9.1
Overview
The switches can be powered by using the same DC source used to power other
devices. A DC voltage range of 12 to 48 VDC (Non PoE) or 48 VDC (PoE) must be
applied between the V1+ terminal and the V1- terminal (PW1), see the following
illustrations. A Class 2 power supply is required to maintain a UL60950 panel listing.
The chassis ground screw terminal should be tied to the panel or chassis ground. A
redundant power configuration is supported through a secondary power supply unit
to reduce network down time as a result of power loss.
Dual power inputs are supported and allow you to connect a backup power source.

for the switch device.
Caution!
Disconnect the power cord before installation or cable wiring.
