2. Installation 2. Installation 2.2.3 Connecting Your SCSI Peripherals All internal SCSI bus connections to the PCI-SC896 host adapter are made with an unshielded, 68-conductor ribbon cable. One side of this cable is marked with a color to indicate the pin-1 side. The connectors on this cable are keyed to ensure proper pin-1 connection. Use Ultra/Ultra2 rated cables for these bus speeds. All external SCSI bus connections to the PCI-SC896 host adapter are made with shielded, 68-conductor cables. The connectors on this cable are always keyed to ensure proper pin-1 connection. Some internal cables come with a SE/LVD on one end. This end should be furthest from the host adapter. 2.2.4 Making Internal SCSI Bus Connections This section provides step-by-step instructions about making internal SCSI bus connections: 1. To connect an internal SCSI device, plug the 68-pin connector on one end of a wide internal SCSI ribbon cable into the connection J4 or J5. 2. Plug the 68-pin connector on the other end of the internal SCSI ribbon cable into the SCSI connector on the internal SCSI device. Pin-1 must match on all connections. 3. To plug in additional internal SCSI devices, use an internal SCSI ribbon cable with the required number of connectors attached along its length. Make sure to match pin-1 on all connections. 4. Most PC cabinets are designed with a front panel LED, which may already be connected to an existing IDE controller. You may connect this LED cable to your SCSI host adapter. This connection causes the front panel LED to indicate activity on the SCSI bus. An LED is also on the PCI-SC896 host adapter, which indicates activity on the SCSI bus. The Busy LED connector J6 is not keyed. The J6 connector is a 4pin one row right angle header for both channel A and channel B. Some LED cables have only two wires. In this case, place the connector on one end of J6. If the LED does not light during SCSI bus activity from this host adapter, you may have to rotate the LED cable 180° on J6.

2.2.3 Connecting Your SCSI Peripherals
All internal SCSI bus connections to the PCI-SC896 host adapter are made
with an unshielded, 68-conductor ribbon cable. One side of this cable is marked
with a color to indicate the pin-1 side. The connectors on this cable are keyed
to ensure proper pin-1 connection. Use Ultra/Ultra2 rated cables for these bus
speeds.
All external SCSI bus connections to the PCI-SC896 host adapter are made
with shielded, 68-conductor cables. The connectors on this cable are always
keyed to ensure proper pin-1 connection. Some internal cables come with a
SE/LVD on one end. This end should be furthest from the host adapter.
2.2.4 Making Internal SCSI Bus Connections
This section provides step-by-step instructions about making internal SCSI
bus connections:
1.
To connect an internal SCSI device, plug the 68-pin connector on one
end of a wide internal SCSI ribbon cable into the connection J4 or J5.
2.
Plug the 68-pin connector on the other end of the internal SCSI ribbon
cable into the SCSI connector on the internal SCSI device. Pin-1 must
match on all connections.
3.
To plug in additional internal SCSI devices, use an internal SCSI ribbon
cable with the required number of connectors attached along its length.
Make sure to match pin-1 on all connections.
4.
Most PC cabinets are designed with a front panel LED, which may al-
ready be connected to an existing IDE controller. You may connect this
LED cable to your SCSI host adapter. This connection causes the front
panel LED to indicate activity on the SCSI bus.
An LED is also on the PCI-SC896 host adapter, which indicates activity on the
SCSI bus. The Busy LED connector J6 is not keyed. The J6 connector is a 4-
pin one row right angle header for both channel A and channel B. Some LED
cables have only two wires. In this case, place the connector on one end of J6.
If the LED does not light during SCSI bus activity from this host adapter, you
may have to rotate the LED cable 180° on J6.
