Hey Guys
I've got a few DEChub90s - sweet things they are too. However, I don't wnt
the bulk of them at the moment until we move to the New House.
I'd like to run one of the modules - a DECserver90TL, not that it matters
really which module it is - standalone.
There's the largeish 16x3 rectangular backplane connector, and a smaller
DIN-ish port. Where does the PSU connect on models that were born to be
standalone?
TIA

Bad news it's the din connector, I 've got one of these as well, but I
can't put up with the noise from the dechub to run it.

If the dnpg website is still up, it used to have a list
of which hub90 modules worked with which of the two
PSU variants. So if you are looking for a suitable
PSU, the actual model *does* matter.
I think the plastic "backplate" that you shove on the
back of a standalone unit to protect the hub90 connector
is common to all hub90 units.
With DEChub900 units (the bigger ones) you actually need
a "plug-in" style of PSU (hard to describe but it fits
along the back end of the whole unit). You'll be happy
to know that there are at least two of these two :-)
The later one has enough oomph to power the AUI
connector too :-)

I'm reasonably sure that when I was hunting for the "what PSU
works with what module" info, the pinouts did crop up. Needless
to say, I cannot find that info right now.

There's the largeish 16x3 rectangular backplane connector,
and a smaller DIN-ish port. Where does the PSU connect on
models that were born to be standalone?
As Dan's already said it's the small DIN port, however bear in mind there
are 2 PSUs, one for standalone DEChub modules and one for the stackable
units whose mnemonic escapes me for now, basically the latter is more
powerful as it needs to run the daisy chain/management module that the
server clips into...

The DIN connector is used for external (standalone) power. The PSU
comes in two flavors - one that has 5.1V, and one that has both the
5.1V *and* a 12V DC supply.. some modules need both, others dont.
I have some extra PSU's, can send one if ya need one.

I have one of these DECserver90TL's too and it came with the WRONG
external power supply so I had to figure it out for myself.
ascii art of the multipin connector:

The picture is looking into the back of the unit with the narrow end of
the connector down.
The pins at the top marked G are ground and the pins marked P are +5V.
I eventually rewired my PS to fix the DIN connector, but my notes don't
show how I did it...
