To configure the firewall:
To access the DSR switch from outside a firewall, configure your firewall to forward ports 80, 443,
2068 and 8192 from its external interface to the KVM switch through the firewall’s internal
interface. Consult the manual for your firewall for specific port forwarding instructions.
NOTE: Port 8192 does not have to be forwarded for DSR1031, DSRx030 and DSRx035 switches.
To connect to the DSR switch on-board web interface:
Open a web browser and enter the external IP address of the firewall. The DSR Explorer will open
and prompt you to login.
Verifying the Connections
DSR switch
The front panel of the DSR switch features LEDS indicating the Ethernet connection for both
LAN1 and LAN2 (if applicable), as well as LEDS that indicate the target device status for
each port.
Ethernet connection LEDS
• The green LED, labeled Link , illuminates when a valid connection to the network is
established at the maximum supported rate and blinks when there is activity on the port.
• The amber LED illuminates when you are communicating at a slower rate when using an
Ethernet connection.
• If neither LED is illuminated, connection speed is at a rate of 10 Mbps.
Target device status LEDS
• A green LED illuminates when the attached target device has power.
• An amber LED illuminates when that port is selected.
• The LEDs blink during a firmware upgrade.
