5. If this is the only expansion box you're connecting, place a terminator on
the unused expansion box SCSI connector. Use the terminator that came
with the expansion box.
The second connector of the last drive in a chain of SCSI devices must
always contain a SCSI terminator. The TURBOchannel extender box
(TCE) has its own internal terminator. If you're using the TCE, you
must always place it last in the chain.
6. Turn on the expansion box power. Then turn on the system unit.

6.5 Linking Storage Devices Together

You can connect up to three expansion boxes, or a total of six individual drives,
to the base system SCSI connector. Once you've connected one expansion box
or drive, connect others as follows:
1. Plug one end of an 18-inch box-to-box expansion cable into the unused
SCSI connector on the back of the expansion box you've already connected
to your system unit.
2. Plug the other end of the cable into one of the SCSI connectors (it doesn't
matter which one) on the new box in the chain.
If the box is a TK50Z tape drive, slide the end of the cable up between the
box and its handle.
