Setting up power
To set up the AC power:
!WARNING:
WARNING: DO NOT turn the computer on until you have verified that the input voltage
selector switch has been set properly. Incorrect voltages will damage
system components.
1. On the back of the computer, between the power cord receptacle and the power
switch, locate the voltage selector switch. Newer models of the Ultra 5 use an
autosensing power supply and do not have a voltage selector switch.
2. If your model has a voltage selector switch, set the voltage selector switch to 115
or 230 V AC depending on your installation.
3. Turn off the AC power switch on the back of the computer.
4. Plug the IEC 320 end of the power cord into the AC connector.
For installations outside of the United States and Canada, obtain a power cord for your
local configuration.
5. Plug the power cord from the computer into an outlet on the UPS.
A UPS provides a temporary electrical supply to a computer for several minutes,
depending on the number of components connected to the UPS. For a CMS computer,
a 2KVA minimum UPS is required for all installations. See your UPS documentation to
determine the projected amount of backup battery time for your model. If the system is
without power for longer than the backup time, the system may shut down improperly,
and the customer could lose data.
If a UPS is not being used, you must use a grounded outlet on a dedicated 15-amp
circuit.
