Query: Great until it broke in 5 months

Bought this switch for the jumbo frames and supposed enterprise-level durability. I found that the switch worked well for 5 months, but one day I found all the lights blinking and it no longer worked. I gather this isn't a rare occurrence for the product. It did seem to get pretty hot while it was still working. Possibly it needs more air vents.
