Termination
This field returns the status of the SCSI fuse on the RF3880 and the condition of terminator power on the SCSI cable connector. It has this format:
BITS
7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
|
|
|
|
|
|
|
|
0 | 0 | 0 | 0 | 0 | BSF | BTP | 0 |
Table 96: Bit Meanings of Termination Field
BTP Bad SCSI Termination Power - Indicates whether there is sufficient voltage on the TERM PWR pin of the SCSI connector.
0 ⇒ Proper 4 - 5.25 volts available.
1 ⇒ Less than 4 volts available.
BSF Blown SCSI Fuse - Indicates whether the Termination Power Fuse on the adapter is intact.
0 ⇒ Fuse is good.
1 ⇒ Fuse is blown.
SCSI Cfig Block
This field reports the status of the SCSI Configuration Block of hardware jumpers. You can use it to determine how the jumpers are set without removing the board from your system:
BITS
7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
1 - 2 | 3 - 4 | 5 - 6 | 7 - 8 | 9 - 10 | 11 - 12 | 13 - 14 | 15 - 16 |
Table 97: SCSI Configuration Jumpers
Each bit corresponds to a hardware jumper.
0 ⇒ Jumper is not present.
1 ⇒Jumper is installed.
The purpose for each jumper is described below:
