Checking the Installation
Before you apply power:
Inspect the equipment thoroughly.
Verify that all cables are installed correctly.
Check cable routing to make sure cables are not damaged or create a safety hazard.
Be sure all equipment is mounted properly and securely.
Applying AC Power
The EX17908 switch has an ON/OFF switch that controls power to the switch. Before you connect the
power cord, select an AC outlet that is not controlled by a wall switch, which can turn off power to the
switch. After you select an appropriate outlet, use the following procedure to apply AC power.
1. Connect the female end of the supplied AC power adapter cable to the power receptacle on the back
of the switch.
2. Connect the 3-pronged end of the AC power adapter cable to a grounded 3-pronged AC outlet.
3. On the rear panel, move the ON/OFF switch to the ON position ( ).
When you apply power:
All green PoE and Link/ACT LEDs blink momentarily.
The fan starts.
The yellow Power LED goes ON.
The Link/ACT LEDs for every port connected to a device flash, as the switch conducts a brief
Power On Self-Test (POST).
After the switch passes the POST, the Link/ACT LEDs for every port connected to a device go ON.
The PoE LEDs also go ON if Power Devices are connected. The switch is now functional and ready to
pass data.
If you do not hear the fan, or if the Power LED is not ON, check that the power cable is plugged in
correctly, the ON/OFF switch is set to the ON position, and that the power source is good and not
controlled by a wall switch. If this does not resolve the problem, see Chapter 5, Troubleshooting.
