Chapter 2: Installation and Configuration
26
A. AC Power
To connect the power supply:
1. Attach the included AC power cord to the Dominion KX II and plug
into an AC power outlet.
2. For dual power failover protection, attach the second included AC
power cord and plug it into a different power source than the first
power cord.
Note: If you only attach one power cord, the power LED on the Dominion
KX II front panel will be red because the system is set to automatically
detect both sources. See Power Supply Setup (on page 135) for
information a
bout turning off automatic detection for the power source
that is not in use.
B. Modem Port (Optional)
The Dominion 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 Dominion KX II (see Specifications (on
page 234) for a list of certified modems and M
odem Setting
s (on page
125) for information on configuring the modem).
Note: Raritan
recommends configuring the modem by enabling the CD
(carrier detect) setting.
C. Network Port
The Dominion 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 Dominion 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 Dominion KX II Ethernet failover
capabilities:
Connect a standard Ethernet cable from the network port labeled
LAN2 to an Ethernet switch, hub, or router.
