Does it work normally if you leave it plugged into the dechub 90
backplane?  I ask because I have a dechub 90 and several modules
(terminal servers, hubs) and the one standalone power supply I
had only worked correctly for some of the modules.  All of them
would power up, but wouldn't work correctly.  Apparently
some of them need (different?) voltages on multiple pins which
the backplane provides but not all power supplies will.

If pluggin them into the backplane doesn't work, I have a spare
decrepeater 90t-16 that works fine or a decrepeater 90ts (8 port
hub and SNMP management station with console port) you could use
to reprogram your 90t-16 if that's the problem.

I also have one of the hubs with 6 10B2 outputs if anyone wants it.
I'm not likely to need 6 coax segments ever again.
