The IP67 Industrial Ethernet switches have communication LEDs for each port, an “OK”
output LED, a status LED and power LEDs. Refer to the sample pictures below for the
location of these LEDs.
The Status LED indicates the overall health of the switch. It is normally ON solid indicating
that no internal CPU or software problems are detected. It will flash when loading firmware
and briefly on power up or reset. Otherwise, if it is OFF or flashing for an extended period of
time then a problem is detected. In this case, please contact your switch supplier for
support.
There is a power LED labeled as Power. It will be on solid when power is applied to the
switch.
The port LEDs are multifunctional and indicate link confirmation, activity, and speed.
Flashing = Indicates that there is a proper Ethernet connection (Link) between the port
and another Ethernet device, and that there is communications activity.
On Solid = Indicates that there is a proper Ethernet connection (Link) between the port
and another Ethernet device, but no communications activity is detected.
Off = Indicates that there is not a proper Ethernet connection (Link) between the port and
another Ethernet device. Make sure the cable has been plugged securely into the ports at
both ends.
The port LEDs are multifunctional and indicate link confirmation, activity, and speed.
ON = A 100 Mbps (100BaseT) connection is detected.
OFF = A 10 Mbps (10BaseT) connection is detected.
This LED is not used in the standard model and will always be off. On special order units
with dual power inputs, the OK LED will be lit when both the P1 and P2 pins have power
applied.

Power and Communication Wiring
The IP67 Industrial Switches can be powered from the same DC source that is used to
power your other devices. 10 to 30 VDC needs to be applied between Pin A and Pin B as
shown below.
NOTE: Any of the available mounting holes may be used for grounding and electrical
bonding of the switch.

Mating Connections Wiring
The IP67 Industrial Switches meet or exceed all MIL-STD-38999 Series III for severe
environmental applications. All connectors and their mating couplings have EMI shielding
and ESD, moisture and corrosion resistance. All mating connectors will self-lock with one
360 degree turn of the coupling nut.
The following mating plugs are suggested to
interface with the switch:
Ethernet Plug
D38999/26WA35PN
(w/ pin contacts and Normal keying)
Power Plug
D38999/26WA98SA
(w/ socket contacts and “A" keying)
USB/RS232 Plug
D38999/26WA35PA
(w/ pin contacts and “A” keying)
Note: The W in the above recommended plugs specifies cadmium plating. However, you
may choose a different plating to meet your requirements. The MIL receptacles on the
switch have black nickel plating which is RoHS compliant.
The maximum cable length for 10/100BaseT is typically 100 meters (328 ft.).
