SCSI connectors The server comes with a 16-bit UltraSCSI controller on the system board, which provides two independent SCSI channels. This controller has two 68-pin, shielded, high-density connectors: one internal, on the controller, and one external, on the back of the server. You can use these connectors to install an additional internal SCSI device in the server or to attach up to fifteen external SCSI devices to the server. Internal SCSI connector: A 2-drop, 68-pin (16-bit) cable is installed in the server. One drop is connected to the backplane, the other drop can connect to an additional SCSI removable media device (not a hard disk drive). This cable is connected to the internal connector for the 16-bit UltraSCSI controller. You can use this cable to install an additional internal SCSI device in the server. External SCSI connector: To attach an external SCSI device to the server, connect an external SCSI cable from the SCSI device to the SCSI connector on the back of the server. Ensure that the last device on the external SCSI cable is terminated. Table 7 shows the pin-number assignments for the 68-pin SCSI connectors. Netfinity 5000 - Type 8659 135

SCSI connectors
The server comes with a 16-bit UltraSCSI controller on the
system board, which provides two independent SCSI
channels.
This controller has two 68-pin, shielded,
high-density connectors: one internal, on the controller,
and one external, on the back of the server.
You can use
these connectors to install an additional internal SCSI
device in the server or to attach up to fifteen external SCSI
devices to the server.
Internal SCSI connector:
A 2-drop, 68-pin (16-bit)
cable is installed in the server.
One drop is connected to
the backplane, the other drop can connect to an additional
SCSI removable media device (not a hard disk drive).
This cable is connected to the internal connector for the
16-bit UltraSCSI controller. You can use this cable to
install an additional internal SCSI device in the server.
External SCSI connector:
To attach an external
SCSI device to the server, connect an external SCSI cable
from the SCSI device to the SCSI connector on the back
of the server.
Ensure that the last device on the external
SCSI cable is terminated.
Table
7 shows the pin-number
assignments for the 68-pin SCSI connectors.
