ETHERNET SWITCH
Installation Guide
NOTE:
If the mounting surface is thin or made of a lightweight material, you may need to add
reinforcing material below the mounting surface in order to support the Ethernet Switch.
3. Place the Ethernet Switch on the mounting surface and align the screw holes with the drilled
mounting holes. Insert the two #8 screws (included) through the screw holes and into the
drilled mounting holes, and hand-tighten using a Phillips screwdriver.
Hand-tighten only!
NOTE:
Apply marine-grade silicone caulk or sealant (separate purchase required) to both
screws and drilled holes as needed to protect your boat from water damage.

Connecting the Ethernet Cables
Up to five Ethernet cables (separate purchase required) can be connected to the Ethernet Switch at
one time. There is no specific order in which the cables have to be connected. Refer to your Ethernet
Networking manual and control head installation guide for the correct procedure for connecting the
cables to the control head.
CAUTION!
Do NOT mount the cables where the connectors could be submerged in water or
flooded. If cables are installed in a splash-prone area, it may be helpful to apply dielectric
grease to the inside of the connectors to prevent corrosion. Dielectric grease can be
purchased separately from a general hardware or automotive store.
1. Confirm that the Ethernet cable is connected to the control head.
2. Unscrew an Ethernet port cover from the Ethernet Switch. Plug the end of the Ethernet cable
into the port.
3. Hand-tighten the screw nut to secure the cable connection.
NOTE:
The connector ports are keyed to prevent reversed installation, so be careful not to
force the connector into the port.
NOTE:
Make sure the port covers are tightly fastened over any unused connector ports.
Connectors that are left exposed may corrode.

Connecting the Power Cable
The Ethernet Switch power cable (included) can be connected to the electrical system of the boat at
two locations: a fuse panel (usually located near the console) or directly to the battery.
CAUTION!
Make sure that the power cable is disconnected from the Ethernet Switch at the
beginning of this procedure.
NOTE:
Humminbird is not responsible for over-voltage or over-current failures. The Ethernet
Switch must have adequate protection through the proper selection and installation of a
3 amp fuse (separate purchase required).
1a. If a fuse terminal is available, use crimp-on type electrical connectors (not included) that
match the terminal on the fuse panel. Depending on your control head model, attach the black
wire to ground (-) and the red wire to positive (+) 12 VDC power. Install a 3 amp fuse (not
included) for the protection of the accessory. Humminbird is not responsible for over-voltage
or over-current failures.
or...
1b. If you need to wire the power cable directly to a battery, obtain and install an inline fuse holder
and a 3 amp fuse (not included) for the protection of the accessory. Attach the black wire to
ground (-) and the red wire to positive (+). Humminbird is not responsible for over-voltage or
over-current failures.
2. Connect the end of the power cable to the port labeled POWER on the Ethernet Switch. The
ports are keyed to prevent reversed installation, so be careful not to force the connector into
the connector port.
3. Hand-tighten the screw nut to secure the cable connection.
