Trantor T348 MiniSCSI Plus Parallel HBAs

Preconfiguration Information

The T348 ends in a male SCSI-1 connector, for plugging into a SCSI-1 device. To connect the T348 to a SCSI-2 device, use a SCSI-1 to SCSI-2 cable (which has a male SCSI-1 connector on one end and a male SCSI-2 connector on the other end) and a SCSI-1 female-to-female adapter (to connect the male end of the T348 to the male end of the SCSI-1 to SCSI-2 cable).

Known Problems and Limitations

• The Trantor MiniSCSI Plus adapter uses electrical power from the TERMPWR signal on the SCSI cable. The adapter will not work unless the first (or only) device connected to it supplies TERMPWR. If you have difficulty using the adapter with the Solaris operating environment, see the "Troubleshooting Notes" section of MiniSCSI Plus User Guide or consult your Trantor dealer.

• Because of low data transfer rates, do not use simultaneous multiple SCSI devices or tape blocks longer than 512 bytes.

• The T348 and attached devices must be plugged in and powered on at boot time to be available during that session.

• If the SCSI devices attached to the T348 fail to respond after a reconfiguration boot and the parallel port had previously been used for a different device, do a second reconfiguration boot.

• The Trantor T338 and T358 are not supported.

• The Exabyte EXB-8500 and EXB-8200 tape drives do not work in the Solaris operating environment when connected to the Trantor T348.

• The Solaris operating environment does not support concurrent use of other parallel devices on the same port as the Trantor T348 or on the T348 pass-through port. To switch between the T348 and another parallel port device, such as a printer or Ethernet adapter, shut down the Solaris operating environment and turn off the computer and any SCSI devices attached to the T348.

  With the power turned off, disconnect the old device and connect the new one. If switching to the T348, turn on any SCSI devices you intend to use. Turn on the computer and do a reconfiguration boot.

• When reconfiguring the system to add other devices, make sure the T348 and all its devices are plugged in and turned on; otherwise they will be removed from the configuration. If you accidentally reconfigure without the T348 plugged in, plug it in and repeat the reconfiguration process.

Configuration Procedure

1. Install the Solaris software.

2. Shut down the Solaris operating environment and turn off the computer.

3. Plug the T348 adapter into the selected (or only) parallel port.

4. Attach all required SCSI devices to the T348.

5. Turn on all the SCSI devices.

6. Turn on the computer.
