How to find IP address assigned to Non Meraki Go Switch?

[Mak]

I have an expensive Netgear XS716T 10GB Managed Switch in my network before adding the Cisco Meraki Firewall Plus GX50 into the network. I have discarded my ISP router and replaced it with the Meraki GX50 Firewall for DHCP assignment.  The problem is, now I am unable to access the GUI interface of my XS716T switch because I can't find its IP address listed in the list of hardware in the GX50 Firewall. 

So my question is, where or how can I find the IP address allocated to my XS716T Switch?  Appreciate any advice from the panel of experts in this forum/ IT community.  Thanks in advance for any assistance.

App or Portal / Network / Select the network / Device Hostname or MAC address

It may help you at minimum to do a reserved IP, but for me I statically assign my infrastructure to avoid these types of issues. Another pro-tip is to create a management VLAN if you haven't done so already.
