11.7.3.4 Terminator power
The drive may be configured to accept terminator power using pin 26 of the
SCSI bus, to supply power to the SCSI bus, or to provide terminator power
for optional internal termination resistors using the drive’s power connector.
The drive can provide power both to its own terminators and to the SCSI bus
terminator power line (pin 26).
SCSI devices providing terminator power (TERMPWR) must have the
following characteristics:
• V TERM = 4.50V to 5.25V
• 800 mA minimum source drive capability
• 1.0A maximum
