Activity LEDs
The KVM/net comes with paired LEDs positioned on each side of the following ports:
The following figure shows the position of the LEDs as they appear on the back of the KVM/net. The LEDs are designed to monitor the interface connections as described in LED Descriptions.
The diagram below shows a close up view of the LEDs on the back of the KVM/net. The LEDS monitor the AUX ports, ETHERNET, and CONSOLE ports as described in LED Descriptions.
LEDs on the KVM/net Management Ports
The LED numbers in the tables below correspond to the numbers in the previous figure.
Monitor KVM CAT5 video interface
Orange - Lights when an internally-generated signal is used. This occurs when the user is not connected to the port and in the OSD, or when the user is connected to a port, but a video signal is not present from the server.
Green - Lights when the server's video signal is used; this happens when the server is presenting a valid signal.
Monitor KVM CAT5 video interface
Green - Lights when the user is connected to port and a video signal is detected and "synchronized". This means that the KVM is presenting the signal to the station.
Orange - Lights when the video signal level is detected but not synchronized. Typically, this takes a very short amount of time (less than 1/3 second) for the KVM to synchronize to the server's video signal upon first connection.
OFF – Indicates the port is not open.
Orange – Lights when DTR (data terminal ready) signal is on (when the port is open).
OFF – Indicates no data activity.
Green – Blinks when data is either being received (RX) or transmitted (TX).
LK/ACT/COL
OFF – Indicates either link is not up or cable is not connected.
Green – Lights solid when the link is up and blinks when data activity occurs, with frequency proportional to traffic.
Orange – Blinks when collisions occur
Off – Indicates the link is 10baseT or no link is active.
Green – Steady when 100baseT link is active.
Green or Orange – Blinks when software is running properly.
Off or solid Green/Orange – During boot up, software crash, etc.
GP/HD
Monitor compact flash (HD) or other (GP)
Orange - Blinks when KVM/net is accessing the compact flash after bootup.
