Ethernet Settings
In the RealPresence Collaboration Server 800s, the automatically identified speed and transmit/receive
mode of each LAN port used by the system can be manually modified if the specific switch requires it.

To modify the automatic LAN port configuration:

1On the Collaboration Server menu, click Setup > Ethernet Settings.
The Ethernet Settings dialog box opens.
The Collaboration Server has 2 LAN ports. You can select the speed and transmit/receive mode
manually for these ports.
2In the Speed column, click the drop-down arrow of the table entry to modify and select the speed
and the transmit/receive mode for each port:
When Auto (default) is selected, the negotiation of speed and transmit/receive mode starts at 1000
Mbits/second Full Duplex, proceeding downward to 100 Mbits/second Half Duplex.
Note: To maximize conferencing performance, especially in high bit rate call environments, a 1Gb
connection is recommended.
