EX17908 Web-Smart Switch User Guide
Checking the Installation
Before you apply power:
ŸInspect the equipment thoroughly.
ŸVerify that all cables are installed correctly.
ŸCheck cable routing to make sure cables are not damaged or create a safety hazard.
ŸBe 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 suppliedAC poweradapter 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:
ŸAll green PoE and Link/ACT LEDs blink momentarily.
ŸThe fan starts.
ŸThe yellow Power LED goes ON.
ŸThe 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.

3 Preparing to Configure the Switch
Topics: After you install the switch, configure it using the switch’s built-in
Web management interface and a Web browser on a PC.
For the Web browser to access the switch’s Web management
interface, the PC and switch must be on the same subnet. This
means the first time you configure the switch, you must change
your PC’s TCP/IP settings to match the switch’s default subnet of
192.168.2.1.
The procedure for changing your PC’s TCP/IP settings depends
on the PC’s operating system. This chapter describes how to
configure TCP/IP settings for PCs that have a Microsoft Windows
7 operating system.
If your PC is running an operating system other than Windows 7,
