4. Power the unit and connect to network Cable
4.1 Wiring Power Inputs
JetNet 5728G/5720G provides 2 types power input, AC power input and DC power input.
It also provides redundant or aggregated power inputs, depending on the voltage of
power input. If there are over 2 power inputs are connected with different voltages, JetNet
5728G/5720G will be powered from the highest connected voltage (redundant power).
If the voltages of power inputs are the same, the total power output will be aggregated
(aggregated power).
AC Power Input
Connect the attached power cord to the AC power input connector, the available AC power
input is range from 100-250VAC.
High Voltage Power Input
The power input support both 100-250VAC power input. Connect the power cord to the
PE for Protective Earth, L / V+ for LINE or V+, N/V- for Neutral or V-. For high power input,
tighten the wire-clamp screws to prevent DC wires from being loosened is must.
DC Power Inputs
The range of the available DC power input is from 46-57VDC. In the IEEE802.3at mode,
the PoE power output is 50~57 VDC, 0.6A, therefore, the suggested DC power input
ranges is 53VDC (52~57VDC). In the IEEE802.3af mode, the PoE power output is 44~57
VDC, 0.35A, therefore, the suggested DC power input is 48VDC (46~57VDC).
If the DC power input is 53VDC, the unit will aggregate the power with the AC power input,
if any.
Follow below steps to wire JetNet 5728G/5720G redundant or aggregated DC power
inputs.
1. Insert positive and negative wires into V+ and V- contacts
respectively of the terminal block connector.
2. Tighten the wire-clamp screws to prevent DC wires from
being loosened.
3. DC1 and DC2 support polarity reverse protection functions.
