The Acme Packet 6400 can be powered by central office –48 VDC operations with a DC-DC supply. The handle on the power supply is used to remove the power supply from the chassis. Move the locking handle from right to left to unlock the power supply. A removable terminal block on the DC power supply serves as the DC power interconnect. The terminal block must be removed before the locking handle can be moved to free the power supply.
