DS500 Status Signal Access Jumper
The DS500 provides chassis status signals for use by a RAID or system controller.
These status signals identify:
•Chassis Over Temperature Condition
•Fan Failure(s)
•Power Supply Failure(s)
•Chassis Failure (Combination of Over Temp and/or Failures)
Status signals are accessed on Jumper P4 located on the DS500 Power Distribution Board
inside of the DS500 chassis (Figure 14). Signal/pin assignments on P4 are also identified.
Figure 14: Power Distribution Board
NOTE: Status signals are all ACTIVE LOW and require the use of a pull-up resistor. To ac-
cess each signal, connect the RAID controller ground to the ground pin on P4, and
make the corresponding status signal connection via a pull-up resistor.
