How to set up DMZ? Need second switch?

Maybe, if you have multiple devices in the DMZ.  One newly-activated UTM port typically connects to tbe DMZ LAN.   That cable can connect to a single host, a second switch, or your existing switch if it is smart enough to support a DMZ VLAN.

You could also use multiple UTM ports in bridged mode if you really want to avoid adding a switch and your DMZ device count is low enough.  But I think you will be happier over the long haul without a bridge configuration.

Thanks for the input. Currently it will only be a single device in the DMZ. How do I go about setting up a bridge mode? I am fairly new to UTM, just cutover to it about 3 weeks ago. Thanks!

Edit: Noticed that you said I would be happier without bridge mode. I wonder if I could get away with a small 4-5 port gigabit desktop switch and just use that.

If you have only a single device, Russ, you don't need  switch, but, yes, a small 4-5-port switch would work just fine.

Great thanks. I ordered a small 5 port gigabit switch. Already am using one so I know I like it.

And bridge mode wouldn't be needed even without the switch.   Doug suggested bridging if you had more than one device, had additional NICs and wanted to avoid adding a switch.
