Yes, there is a terminator behind one of the fans.

Subject: Re: Confused by Alpha 433au and SCSI
Is there a SCSI terminator on the back of the shelf? I can't get to any
of my
BA356 shelves to look, but I have used BA350's a
lot and they have a
terminator hidden by one of the fans.
BTW, I tried to get a BA356 running on my 433au, and never succeeded, I
used BA350's till upgrading to Andataco JBOD boxes. I was never able to
determine if the issue was with the 433au or the BA356 (my 433au has some
fairly serious issues including a dead PCI slot, but was still stable if
configured
right).

I have a BA356 shelf with a DS-BA35X-FB
personality module. The
personality module has two high density connectors on it, I think they
are 68-pin. The pins are too small for me to be able to count them
reliably, but the cable has a 68-pin SCSI Wide connector on the other
end. The second connector on the personality module is not connected to
anything, I do not have a terminator for it and I am unsure if I need
one. I have connected this to my 433au which has a Qlogic QLA1040 SCSI
adapter in it. I have been unable to locate any documentation for
either the personality module or the SCSI adapter.
I am having problems getting the SRM to recognise the disks in the shelf.
Sometimes it will see no devices at all, not even the CD-ROM connected
to the internal SCSI cable. Other times it will see a ton of disks as
shown in this partial extract from the console:

I am not quite sure what is going on, what the jumpers on the
personality module do, whether I need to insert a terminator on the
second personality module connector, or whether there are some jumpers
on the QLA1040 adapter that need to be set, or is there something else I
Anyone have any clues?
Thanks
