2.5.3
Connecting external PoE power
The device supports up to twenty-four 10/100/1000 Mbps Power-over-Ethernet (PoE)
ports that require external power. An external PoE output power supply, such as the
RUGGEDCOM RPS2410, can be connected to the device via the PoE and failsafe alarm
relay power terminal block.
Electrocution hazard – risk of serious personal injury
The PoE power supply is intended to have a local connection to a PoE DC output
power supply. Make sure the power source for PoE power is galvanically isolated
from mains electricity and chassis/earth ground with at least 1500 VAC/2250 VDC of
isolation.
Electrical hazard – risk of damage to the device
Do not connect or disconnect the PoE terminal block when the external power
supply is energized.
Note
IEC 61850 compliance
For IEC 61850 compliance, use an IEC 61850 compliant PoE power supply with
power cabling no longer than 3 m (118 in).
Otherwise, Siemens recommends using the RUGGEDCOM RPS2410 switch-mode AC
power supply. For more information about this power supply, refer to
