Nearly every SGI I've ever dealt with has answered the termination question the same for internal drives.

There is normally automatic termination at the end of the chain and you do not need or ever should enable termination for an internal drive. Indy is a passive terminator crimped permanently onto the end of the internal ribbon which means it is already terminated for you.

External devices are a totally different story as there is no provided termination. So you would only terminate external devices yourself. On Indy I have placed an additional external terminator right on the rear of the machine with no ill-effects as it's recognized as a device and the internal termination is disabled.

The only time I've seen this rule not hold is on the internal 50 pound narrow SCSI chain for a Fuel. I believe that on Fuels that came with an optical drive you got the long 50-Pin SCSI-2 cable and since the drive is the last on the internal chain the drive's internal termination is utilized as there is no attached terminator on the ribbon cable. This is the only time I've witnessed an internal drive chain on an SGI that didn't automatically terminate.
