D-Link DES-3250TG Standalone Layer 2 Switch
Power on
The DES-3250TG switch can be used with AC power supply 100 - 240 VAC, 50 - 60 Hz. The power switch is located at the
rear of the unit adjacent to the AC power connector and the system fan. The switch’s power supply will adjust to the local
power source automatically and may be turned on without having any or all LAN segment cables connected.
After the power switch is turned on, the LED indicators should respond as follows:
• All LED indicators will momentarily blink. This blinking of the LED indicators represents a reset of the system
•
The power LED indicator is always on after the power is turned ON
• The console LED indicator will blink while the Switch loads onboard software and performs a self-test. It will
remain ON if there is a connection at the RS-232 port, otherwise this LED indicator is OFF
Power Failure
As a precaution in the event of a power failure, unplug the switch. When the power supply is restored, plug the switch back in.
