Grounding the Moxa Industrial Rackmount Switch
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
ground screw to the grounding surface prior to connecting devices.
NOTE
Using a shielded cable achieves better electromagnetic
compatibility.
Connecting the Power Inputs
The IKS-6728A-8PoE switches support 4 types of power supply.
•
IKS-6728A-8PoE-4GTXSFP-HV-HV-T: Two isolated 110/220 VAC (85
to 264 VAC) power supplies for switch and two isolated 48 VDC power
inputs for PoE+ ports
•
IKS-6728A-8PoE-4GTXSFP-HV-T: One isolated 110/220 VAC (85 to
264 VAC) power supply for the switch and one isolated 48 VDC power
input for the PoE+ ports
•
IKS-6728A-8PoE-4GTXSFP-48-48-T: Two isolated 48 VDC power
supplies for switch and PoE+ ports
•
IKS-6728A-8PoE-4GTXSFP-48-T: One isolated 48 VDC power supply
for switch and PoE+ ports
For the HV models, the 110/220 VAC power supplies provide power for
switch operation. Separate 48 VDC power supplies are required to provide
power to all PoE+ ports (50 to 57 VDC is recommended for IEEE 802.3at
devices).
For the 48 VDC models, the 48 VDC power supplies provide power for
switch operation and to all PoE+ ports (50 to 57 VDC is recommended for
IEEE 802.3at devices).
The IKS-6700A switches support 3 types of power supply:
•
IKS-6726A/6728A HV series: Two isolated 110/220VAC (85 to 264
VAC) power supplies for switch
•
IKS-6726A/6728A 24/48VDC series: Two isolated 24 or 48VDC power
supplies for switch
Wiring Requirements
WARNING
Do not disconnect modules or wires unless power has been
switched off or the area is known to be non-hazardous. The
device may only be connected to the supply voltage shown on the
type plate. The device is designed for operation with a Safety
Extra-Low Voltage (SELV) or an isolated power supply, which
means that they may only be connected to the supply voltage
connections and to the signal contact with a SELV or an isolated
power supply in compliance with IEC 60950-1/EN 60950-1 or UL
508.
AC Power Inlets
The connection for PWR1 (power supply 1) and PWR2 (power supply 2)
are located on the rear panel (shown below). Be sure to use a standard
