Apply Power to the Platform
Power is provided to the platform from the desktop power supply. Each
R400 is shipped with one 90-264V AC external power supply. The
power supply is equipped with an S760 hollow-type plug for insertion
into the power input jack located on the back of the platform. To con-
nect to the power source, the AC power supply provides a standard IEC
320-type AC power receptacle.
The R400 supports a secondary power supply if redundant power is re-
quired. Refer to Operating Features of the Load-Sharing Power Supply
in the User Guide section for further information regarding redundant
power.
IMPORTANT: Connect the power cord to the input jack located on the
back panel before connecting to the power source.
Follow the steps outlined below to apply power to the platform.
• Insert the end of the power cord into the primary jack labeled “A.”
• If using two power supplies, insert the end of the second power cord
into the secondary input jack labeled “B.”
• Connect to the power source by plugging the AC power receptacle
into an outlet. If a second power supply is being used, connect each
power supply to a separate power source.
• To prevent accidental disconnections, seat the power cord(s) into the
strain relief clip(s).
