Connection
A server is connected to one of the host ports.
There is no need for further termination
configuration because the firmware default is
terminator ON, and the auto-sense terminator is
also automatically enabled.
Figure 4- 4: Dual Host Connection: Correct
Connection
The "IN" and "OUT" ports are separately
connected to a server and a cascaded enclosure.
The auto-sense terminator is automatically
disabled, and the firmware setting should be
manually disabled.
The firmware default for SCSI bus termination setting is "ON." The bus termination
setting can be manually enabled or disabled on each SCSI channel. See the diagrams
below for different accesses to the termination control. More details about the
configuration process can be found in the Generic Operation Manual or the
RAIDWatch User's Manual that came with the Product Utility CD.
