Chapter 3 – Connecting Additional Peripherals GenesisMP30 ◆
If the device will be connected to another device, you will typically use the SCSI
peripheral interface cable (50-pin to 50-pin).

SCSI Peripheral Cable
Note: Use only high quality SCSI cables with 110-ohm impedance such as those
from Apple Computer. Also, the entire length of the external SCSI bus (the total
length of the SCSI chain)should not exceed 20 feet (6 meters).
Some Additional Information about SCSI Cables and SCSI Chains
• There are two common types of external SCSI connectors: 25-pin and 50-pin.
(SCSI-II PCI cards with external ports often have a third type of connector.)
• Genesis MP has a 25-pin external SCSI connector.
• The first external connection from your Genesis MP is typically with a 25-pin
to a 50-pin cable. This cable can also be used to connect a device with a 25-pin
connector to a device with a 50-pin connector in the SCSI chain.
• A 50-pin to 50-pin is generally required to connect external SCSI devices to
one another in the SCSI chain.
• A 25-pin to 25-pin cable is generally required to connect Genesis MP to a
device with a 25-pin connector, such as the Iomega Zip drive. This type of
cable can also be used to connect two 25-pin devices to one another in the
SCSI chain.
