Gigabit Ethernet Switch User's Guide
AC Power Connector This is a three-pronged connector that supports the power cord. Plug in the
female connector of the provided power cord into this connector, and the male into a power outlet.
Supported input voltages range from 100 ~ 240 VAC at 50 ~ 60 Hz.
Side Panels
The Switch's side panels contain the system fans, two on the right and one on the left. The following shows the
Switch's right side panel.
System Fans These fans are used to dissipate heat. The sides of the system also provide heat vents to
serve the same purpose. Be sure not to block these openings, and to leave adequate space at the rear
and sides of the Switch for proper ventilation. Remember that without proper heat dissipation and air
circulation, system components might overheat, which could lead to system failure.
LED Indicators
The LED indicators of the Switch include Power, Console, Link/ACT, and Full. The following shows the LED
indicators for the Switch along with an explanation of each indicator.
Power After turning on the power, the Power indicator on the front panel should light to indicate the
Switch is loading onboard software. This indicator should then remain on to indicate the ready state of
the Switch.
Console This LED indicator is lit when the Switch is being managed via out-of-band/local console
management through the RS-232 console port using a straight-through serial cable. When a secured
connection is established, this LED indicator is lit. Otherwise, it remains dark.
