DGS-3100 Series Gigabit Stackable Managed Switch Hardware Installation Guide
Powering on the Device
The device can be used with AC power supply 100-240 VAC, 50 - 60 Hz. The device’s power supply adjusts to the local
power source automatically, and can be powered on without having any or all LAN segment cables connected.
After the device is plugged in:
• All LED indicators, except console, momentarily flash. Flashing LEDs indicate the system is being reset.
• The console LED indicators flash while the device loads software and performs a self-test. When the POST is
passed, the LED darkens. If the POST fails, the LED lights solid amber. This indicator lights solid green when the
device is being logged-in via a local console management port (RS-232) using a straight-through serial cable.
CAUTION: In the event of a power failure, unplug the device. When power is resumed, plug the device
back in.
