Hardware Overview
Power Button
The power button is located on the left side of the front panel. You use the power
button to power the device on and off. When you power on the device, ScreenOS
starts as the power supply completes its startup sequence. See “Powering the

Reset Config Button
The Reset Config button restarts the device. You press this button by inserting a
thin, firm wire (such as a straightened paper clip) into the pinhole on the front
panel. You can also restart the device using the CLI and WebUI interfaces. See
“Restarting the Device” on page 41 for more information.
Device Status LEDs
The Device LEDs show information about current device status. Figure 2 illustrates
the position of each LED on the front of the SSG 500-series device.
