The AC power connector is a standard three-pronged connector that supports the power cord. Plug-in the female
connector of the provided power cord into this socket, and the male side of the cord into a power outlet. Supported
input voltages range from 100 ~ 240 VAC at 50 ~ 60 Hz.
Side Panels
The right side panel of the Switch contains two system fans (see the top part of the diagram below). The left side panel
contains heat vents.

The system
fans are used to dissipate heat. The sides of the system also provide heat vents to serve the same
purpose. Do not block these openings, and leave at least 6 inches of space at the rear and sides of the switch for
proper ventilation. Be reminded 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 RPS In Use. The following shows the LED
indicators for the Switch along with an explanation of each indicator.
•
Power
– This indicator on the front panel should be lit during the Power-On Self Test (POST). It will light green
approximately 2 seconds after the Switch is powered on to indicate the ready state of the device.
•
Console
– This indicator is lit green 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.
•
Link/Act
–
T
hese indicators are located to the left and right of each port. They are lit when there is a secure
connection (or link) to a device at any of the ports. The LEDs blink whenever there is reception or transmission (i.e.
Activity--Act) of data occurring at a port.
•
RPS in Use
–
This indicator is lit when the optional
DPS-1000 Redundant Power Supply
is being used.
