I started this separate thread (per request) for future reference and discussion of the Quanta LB4M 48p gbE + 2x 10gbE sfp+ switch and this old ebay thread is the source.
I picked up three Quanta LB4M switches from an Omaha, NE eBay seller brandon-nettech. It was listed at $205 + free shipping. The 55 pound box that the three LB4M's arrived in was very well packed - bubble wrapped and packed tightly in styrofoam peanuts in a thick cardboard box.
These units seem very serviceable. Only two phillips screws to take the top lid off and 5 screws to remove the daughter card.
Here is the 900+ page pdf manual for this beast.
Pictures of the actual unit.
