Replace a DC power supply in a dual-supply system
Before you perform a DC power supply unit (PSU) replacement, you need to provide these tools and
components:
• 12 AWG copper cable long enough to reach from the platform to the DC power source
• Flat-head or Philips head screwdriver
In the event of a power supply failure, you can replace a DC power supply unit (PSU) in a dual-supply
system without powering down the system, provided that there is at least one PSU operating during the
replacement process.
Caution: Be sure that you are using the correct wattage power supply when performing a power supply
replacement.
