Power Control
Does the power supply used by the KSX II automatically detect
voltage settings?
Yes. The KSX II's power supply can be used in AC voltage ranges from
100-240 volts, at 50-60 Hz.
What type of power control capabilities does the KSX II offer?
Raritan's Remote Power Control power strips can be connected to the
KSX II to provide power control of the KVM target servers. After a simple
one-time configuration step, just right click the server name to power on,
off, or recycle a hung server. Note that a hard reboot provides the
physical equivalent of unplugging the server from the AC power line, and
reinserting the plug.
Does the KSX II support servers with multiple power supplies?
What if each power supply is connected to a different rack PDU
(power strip)?
Yes. The KSX II can be easily configured to support multiple power
supplies connected to multiple power strips. Two (2) power strips can be
connected to a KSX II device. Four power supplies can be connected per
target server to multiple power strips.
Does remote power control require any special server
configuration?
Some servers ship with default BIOS settings such that the server does
not automatically restart after losing and regaining power. For these
servers, see the server‟s documentation to change this setting.
What type of rack PDUs (power strips) does the KSX II support?
To take advantage of the KSX II's integrated power control user interface
and, more importantly, integrated security, use Raritan's Remote Power
Control (RPC) power strips or Dominion PX power strips. A CAT5 cable
is used to connect the PDU port on the KSX II to a PX or RPC unit.
The Dominion PX is an intelligent power distribution unit that allows you
to reboot remote servers and other network devices, and monitor power
in the data center, through Raritan's KVM switches and Secure Console
Servers.
