Power over Ethernet
The MR3000C/TR provides the option to be used as a Powered Device (PD) using Power over
Ethernet (PoE) according to IEEE 802.3af standard. An appropriate commercial/industrial PoE
switch along with a 48 VDC supply allows you to use the LAN connector as a combined
communication/power plug.
The PoE switch injects the 48 VDC into the data lines which are then extracted by the
MR3000C/TR. According to the selected PoE switch, multiple instruments may be linked to a
combined communication/power network. Optionally a battery or UPS may be hooked to the PoE
switch to accommodate for power interruptions.
Note: A PoE surge protection may be added close to the MR3000 for internal PoE protection.

Combined Power Options
The MR3000 may also be powered by a combination of PoE and an auxiliary external 12 VDC
supply (battery or AC/DC). In this case, the MR3000 automatically manages the power sources.
