Fujitsu M2511A:Switch Settings
PCA Layout All configurations marked "*" are default settings
There are two different layouts of PCA for this drive therefore serial numbers must be checked before adjustments are made. The only functional differences are in terminal CNH1 and CNH2. See the board layout diagram for the physical differences. The functions of switch bank SW1 and SW2 remain the same. To maintain backward compatibility, an external connector designed for the early version PCA for CNH2 will fit directly on to the pins 2, 4, 6, and 8 of the later version.

SCSI Terminating Power 1-2 3-4 Function SHORT(*) SHORT(*) Power is supplied from the drive to both the terminating resistor pack and the TERMPWR pin on the SCSI bus. (Pin 26) OPEN SHORT The TERMPWR pin is not used. Power is supplied to the drive terminating resistor only from the drive. SHORT OPEN Power is not supplied to the terminating resistor from the drive, only from the TERMPWR pin.
Terminal CNH1 (For drives with serial below 30,000)
SCSI Terminating Power 1 - 2 SHORT(*) The TERMPWR pin is not used. Power is supplied to the drive terminating resistor only from the drive. 2 - 3 SHORT Power is not supplied to the terminating resistor from the drive, only from the TERMPWR pin. (Pin 26)
