Note: If you only attach one power cord, the power LED on the KX II front
panel will be red because the system is set to automatically detect both
sources. See Power Supply Setup
turning off automatic detection for the power source that is not in use.
B. Modem Port (Optional)
The KX II features a dedicated modem port for remote access even
when the LAN/WAN is unavailable. Using a straight-through serial (RS-
232) cable, connect an external serial modem to the port labeled
MODEM on the back of the KX II. See
a list of certified modems and
158) for information on configuring the modem.
Note: Raritan recommends configuring the modem by enabling the CD
(carrier detect) setting.
C. Network Port
The KX II provides two Ethernet ports for failover purposes (not for load-
balancing). By default, only LAN1 is active and the automatic failover is
disabled. When enabled, if the KX II internal network interface or the
network switch to which it is connected becomes unavailable, LAN2 will
be enabled using the same IP address.
Note: Because a failover port is not activated until after a failover has
actually occurred, Raritan recommends that you either not monitor the
failover port or monitor it only after a failover occurs.
To connect the network:
1. Connect a standard Ethernet cable (included) from the network port
labeled LAN1 to an Ethernet switch, hub, or router.
2. To make use of the optional KX II Ethernet failover capabilities:

Connect a standard Ethernet cable from the network port labeled
LAN2 to an Ethernet switch, hub, or router.

Enable Automatic Failover on the Network Configuration page.
Note: Use both network ports only if you want to use one as a failover
port.
