* Not completed drawing.


Note: Do Not Use: Old power supplies (631AR, 631BR, 631WA, and 631WB) are not to be used in this carrier because if they are mixed and matched with new power supplies, (631DA and 631DB) in the this carrier the old power supply shorts out the new power supply that is installed at the other end of the carrier. In a hot plug-in situation this can cause arcing that damages backplane pins and power supply connector contacts.
