OK, it was some time ago, it well could be a Challenge
L. it was a big box,
and was powered by a big 28 V power supply. (Or, was it a 48 V supply?)

It should be 48v. A 9uish VME style card cage. The Challenge XL / Full
rack Onyx and the Onyx / Challenge L should all share the same memory.
All those machines are pretty cool.
