Power Supplies

The switch contains two power supply assemblies with internal cooling fans. The
redundant, load-sharing power supply assemblies step down and rectify facility
input power to provide 3.3 volts direct current (VDC), 5 VDC, and 12 VDC to the
control processor (CTP) card. The power supplies also provide input filtering,
overvoltage protection, and overcurrent protection. An amber LED on each
assembly illuminates if the FRU fails.
Either power supply can be replaced while the switch is operational. Each power
supply has a separate connection to the CTP card to allow for independent AC
power sources. The power supplies are input rated at 90 to 264 volts alternating
current (VAC).
