Power Supply (P/Ns 80005 and 80005A)
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…
●
A 4 Slot Cabinet can use either an A series or non-A series power supply.
●
An 8 Slot Cabinet can use only A series power supplies.
●
In an 8 Slot Cabinet, you must have a power supply for every 2 16DSTU
PCBs installed.
Be sure to review DS2000 System Configuration on page 18 for help on deciding how many power
supplies your 8-Slot Cabinet requires.
