2.7 POWER SUPPLY INSTALLATION
2.7.1 OVERVIEW
Power down and disconnect the power cord before servicing or wiring the switch
Do not disconnect modules or cabling unless the power is first switched off.
The device only supports the voltage outlined in the type plate. Do not use any other power
components except those specifically designated for the switch device.
Disconnect the power cord before installation or cable wiring.
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 24 to 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.
SEC510-2SFP-T and SEG510-2SFP-T support 12 to 48 VDC and SECP510-2SFP-T and SEGP510-
2SFP-T support 24 to 48 VDC. Dual power inputs are supported and allow you to connect a
backup power source.
