Enable termination on a SCSI channel if the controller is installed at one end of the channel. This setting terminates the channel and powers the SCSI TERMPWR signal. Disable termination on a SCSI channel if the controller is not at the end of the channel (i.e., both external and internal devices exist on the same channel). | ||||

Status |
Condition |
|
J6/pins 1 & 2 |
On |
SCSI is active (Data is being transmitted/received across SCSI channels) |
|
J6/pins 1 & 2 |
Off |
No SCSI activity |
|
J6/pins 3 & 4 |
On |
PCI is active (Data is being transmitted/received to/from host) |
|
J6/pins 3 & 4 |
Off |
No PCI activity |
|
J6/pins 5 & 6 |
On |
Write is pending (Cache holds data that needs to be written to disk) |
|
J6/pins 5 & 6 |
Off |
No write is pending |
|
Note: If the system loses power or is reset while J6/pins 5 & 6 are on, the data in cache memory will be lost. Installing optional cache battery backup module J2 will avoid data loss. | ||
