Power Supply (P/Ns 80005B and 80005C)
The power supply provides the various DC voltages required to power the sys-
tem’s PCBs. The 4-Slot Cabinet requires a single power supply. The 8-Slot Cabi-
net requires up to 3 power supplies, depending on system configuration.
Make a note of the following…
● You can mix P/Ns 80005B and 80005C in the same system.
● In an 8-Slot Cabinet, you must have a power supply for every 2 16DSTU
PCBs installed.
● If the system uses UltraMail or UltraMail 2000, you must install only
power supply P/N 80005C.
Be sure to review DS2000 System Configuration on page 22 for help on deciding how many power
supplies your 8-Slot Cabinet requires.
