Power on
The switch can be used with AC power supply 100-240 VAC, 50 - 60 Hz. The switch’s power supply will
adjust to the local power source automatically and may be powered on without having any or all LAN
segment cables connected.
After the switch is plugged in, the LED indicators should respond as follows:
• All LED indicators except console will momentarily blink. This blinking of the LEDs indicates a
reset of the system.
• The console LED indicator will blink while the switch loads onboard software and performs a
self-test. When the POST is passed, the LED will become dark. If the POST fails, the indicator will
light solid amber. This indicator lights solid green when the switch is being logged-in via out-of-
band/local console management through the RS-232 console port using a straight-through serial
cable.
Power Failure
As a precaution in the event of a power failure, unplug the switch. When power is resumed, plug the
switch back in.
External Redundant Power System
The switch supports an external redundant power system.
