It has zero 10g ports:

  N1108T-ON: 
  1GbE Port Attributes Multi-speed:
  8x 10/100/1000Mbps half/full duplex RJ45 ports
  1GbE Port Attributes Single-speed:
  2x 1000Mbps half/full duplex RJ45 ports
  Integrated 1GbE SFP dedicated ports: 2
  Integrated 10GbE SFP+ dedicated ports: N/A

My mistake. OK, it's just a reasonably cheap fully managed switch (at 85 pounds, anyway).

Easy mistake tbh - the larger switches in the range (i.e. 24 & 48 port models) do have 4 x 10Gb ports, and aren't much more pricey.
