I ordered that USW 8 Ent switch from Amazon third party seller, then tried to cancel about 1hr later... thought maybe I should order from a different vendor for cheaper, but it said it had already been sent for fulfillment.
It arrived today via FedEx and is now up and running... using a Mikotik S+RJ10 rev2 to get a 10G link to my basement over CAT6. Runs very hot so I pointed a small fan at the switch/SFP module. Have again deferred drilling holes around the house and crawling in the attic to run fiber.
