Power Supply Installation
2.7.1
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), 24 to 48 VDC (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 second
-
ary power supply unit to reduce network down time as a result of power loss.
EKI-7712G-4F/EKI-7712G-4FI/EKI-7712E-4F/EKI-7712E-4FI support 12 to 48 VDC,
and EKI-7712G-4FP/EKI-7712G-4FPI support 48 VDC. Dual power inputs are sup
-
ported and allow you to connect a backup power source.
