5.5 SCSI Bus Page. This page is used to configure certain parameters specific to the
SCSI bus interface. Namely:
5.5.1 SCSI ID: You must choose a unique value for this ID. No other device
on the SCSI bus can have a duplicate ID.
5.5.2 Termination: The iSCSI Bridge has on-board terminators. You can toggle
these terminators on/off via this page.
5.5.2.1 If you turn the terminators off and the Bridge is at the end of the SCSI
bus, i.e. your system has the topology of section 4.3 Figure C, you will
need an external terminator at Bridge end. Also make sure that the
opposite end of the bus is properly terminated.
5.5.2.2 If you turn the terminators off and the Bridge is in the middle of the
SCSI bus, i.e. your system has the topology of section 4.3 Figure D,
make sure that the ends of the bus are properly terminated.
5.5.3 Terminator Power: Paralan’s iSCSI Bridge is capable of supplying
enough power to the SCSI bus to turn on 1 set of terminators. The user
can optionally turn this power supply off.
5.5.4 Force Single Ended SCSI: The user can optionally force the SCSI bus to
Single-Ended communications.
5.5.5 Force Ultra SCSI: The user can optionally slow the SCSI bus down to
Ultra speeds (40MB/s).
WARNING! Regardless of the topology, a powered terminator must be
on the SCSI bus for the system to operate correctly! For changes to this page
to take affect, you will need to click the submit button and confirm changes. A
full reboot of the unit is the final step necessary to make the modifications
permanent.
