How are you going to check link if you do not have jack’s LED(s) connected?

Hi. Thanks for the reply, unfortunately had to change the ethernet port last minute so missed them. But connecting to multiple switches I don’t see any activity on the switch side.

Ok, the link LED on the W5500 side is required to see if chip is alive when you connect live ethernet cable to it. However, I suspect that if it outputs (proper) carrier remote device must show the link.
So the first thing you must ensure the proper reset (hardware + software), and then without (even trying) programming chip through SPI after power on connect cable and see if link LED goes on (try both direct and crossover as W5500 is not MDIX). If link LED does not light up - you have problems with hardware.

Overall, the circuit diagram is weird, please follow the reference circuit diagram below.
