Installing the Switch
Installation Procedure
The switches automatically adjusts to any voltage between 100-127 or 200-240
volts and either 50 or 60 Hz. There are no voltage range settings required.
The 1810-8 and 1810-8G Switches also do not have a power switch. They are
powered on when the external AC/DC power adapter is connected to the
switch and the adapter power cord to a power source. The external AC/DC
power adapter automatically adjusts to any voltage between 100-240 volts and
either 50 or 60 Hz.
2. Check the LEDs on the switch as described below.
When the switch is powered on, it performs its diagnostic self test. The
self test takes approximately 45 seconds to complete.
Self Test LED Behavior:
During the self test:
• Initially, the Power, Fault, Locator, and all port LEDs turn on.
• After several seconds, the Power, Fault and Locator LEDs remain on,
and the port LEDs turn off. Then each port Link LED is sequentially
turned on, then off.
•The Fault and Locator LEDs turn off when the self test completes.
When the self test completes successfully:
•The Power LED remains on.
•The Fault, and Locator LEDs stay off.
• The port LEDs on the front of the switch go into their normal opera-
tional mode:
