Power Supplies

Redundant, load-sharing power supplies step down and rectify facility input
power to provide 3.3 volts direct current (VDC), 5 VDC, and 12 VDC to the CTP.
The power supplies also provide input filtering, overvoltage protection, and
overcurrent protection. Either power supply can be replaced while the switch is
