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

| LED | Status | Condition |
|----------------+--------+----------------------------------|
| JP5/pins 1 & 2 | On | SCSI is active |
| | | |
| | | (Data is being |
| | | transmitted/received across SCSI |
| | | channels) |
|----------------+--------+----------------------------------|
| JP5/pins 1 & 2 | Off | No SCSI activity |
|----------------+--------+----------------------------------|
| JP5/pins 3 & 4 | On | PCI is active |
| | | |
| | | (Data is being |
| | | transmitted/received to/from |
| | | host) |
|----------------+--------+----------------------------------|
| JP5/pins 3 & 4 | Off | No PCI activity |
|----------------+--------+----------------------------------|
| JP5/pins 5 & 6 | On | Write is pending |
| | | |
| | | (Cache holds data that needs to |
| | | be written to disk) |
|----------------+--------+----------------------------------|
| JP5/pins 5 & 6 | Off | No write is pending |
|------------------------------------------------------------|
| Note: If the system loses power or is reset while JP6/pins |
| 5 & 6 are on, the data in cache memory will be lost. |
| Install the optional cache batter backup module J2 to |
| avoid data loss. |
