KE6900 / KE6940 LAN Installation
Setting up the units on a network allows point-to-point, point-to-multipoint,
and multipoint-to-multipoint computer to console operation by connecting
multiple KE6900 / KE6900ST / KE6940 devices on the same TCP/IP LAN.
Prior to the setup, we recommend laying out the plans for your KE installation
using our performance guide (see
Keys to Network Performance , page 433).
A few points to note during your setup:

The units are preconfigured with factory-default network settings. If you
install only one set of KE Series units, you do not need to change these
default network settings. See
Default IP Addresses , page 154, for further
details.

In a network setup with multiple units, each Transmitter and Receiver
must be configured with a unique IP address. See
Network Configuration ,
page 153, for further details.
 We recommend using 1000-Mbps Gigabit Ethernet switches (wire speeds,
non-blocking with 1 Gbps / 1.5 Mpps performance per port) between KE
Series devices installed on different LAN segments under a same office
network environment. 10/100 Mbps switches might cause poor
performance.

In multipoint configurations, the IGMP and flow control function of your
network switches/hubs must be enabled to avoid the deterioration of data
throughput. To ensure functionality use a layer 3 switch that supports
IGMP queries.

If your network uses cascaded switches, please check to ensure the data
throughput is sufficient.
 To get the best performance, we suggest creating a private network for KE
devices, as they are bandwidth-intensive devices.
Make sure that all equipment is powered off. Refer to the installation diagram
on the following page, and do the following:
1. On the Transmitter side, plug the mouse, keyboard, DVI monitor,
microphone, and speakers into the ports on the console section of the
KE6900T / KE6940T.* Each port is marked with an appropriate icon to
indicate itself.
2. Connect the USB KVM cable provided to the KVM ports on the front of
the KE6900T / KE6940T.
