Front-Panel Components
The front panel of the Switch consists of LED indicators, an RS-232 communication port, and four SFP (Mini-
GBIC) combo ports.

Comprehensive LED indicators display the status of the switch and the network.
An RS-232 DCE console port for setting up and managing the switch via a connection to a console terminal or
PC using a terminal emulation program.
LED Indicators
The LED indicators of the Switch include Power, Master, Console, and RPS (Redundant Power Supply). A bank
of 24 LEDs (2 for each port) indicates link, activity status and connection speed for each port
Power
It will light green approximately 2 seconds after the switch is powered on to indicate
the ready state of the device.
Master
Lights steady green when the Switch is configured as the Master Switch in a stack.
Console
This indicator on the front panel should be lit during the Power-On Self Test (POST).
Lights 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.
RPS
This indicator will light steady amber when an external power supply is supplying
power. This indicates the internal power supply has failed.

Link/Act
Each on-board Gigabit Ethernet port has a corresponding indicator. This will light
steady green for a valid link and blink whenever there is reception or transmission
(i.e. Activity--Act) of data occurring at a port.
Stack ID
The switch includes a 7-segment LED (labeled
STACK ID
) to indicate the switch
status in a stacked switch group.
SIO
Indicates which stacking port, if any, is in use.
