Jay:
There is an easy visual way to tell if your disk shelf(s) need a FC-AL terminator. If you see two fans on the back of the disk shelf, then you are looking at an FC-7 or FC-8 disk shelf. In this case, you would need to terminate the loop with a FC-AL terminator. If you see three fans on the back of the disk shelf, then you are looking at an FC-9 shelf. An FC-9 shelf does NOT have to be terminated. Another way to verify that you have an FC-9 is that you will have two power supplies with green buttons on the left hand side of the shelf - the older shelfs did not have green buttons on the power supplies.
As far as terminating the filer, check the back of the filer. Towards the right rear of the filer, there will be an FC-AL port. If you see one or more PCI-based FC-AL adapter cards installed, then you should terminate the FC-AL port on the back of the filer and connect the disk shelf to the FC-AL card.
Hope this proves helpful. Don't forget that you can always access the NOW site on the web for specific configuration information.

We recently purchaced a FC-AL 720, and I asked about the terminator. I was told it depends on the model of the drive-shelf as to whether or not it self terminates. Don't remember which was which though.

I believe if you have FC9's you don't need the terminator... they're auto-terminating...
It sounds like his disk shelf is connected to a slot-based FC-AL
adapter, so he still needs the terminator for the on-board adapter (matching his description of a serial port). -- Brian Tao (BT300, taob@risc.org) "Though this be madness, yet there is method in't"
