I have multiple devices connceted to an HP 1910-48g managed switch . Three of them are fingerprint scanner devices. We use them for time attendance reports.
Because of some problems I have to reinstall software but in order to configure the software I need to find their IP addresses. I was able to find one of device's IP address from old software. For the rest of them I tried a network scanner but I couldn't find the addresses.
Perhaps they are on a different subnet. Is there any way to narrow the search down?

This will work if the scanner has static IP.
Disconnect the scanner from HP 1910-48g and put in on a separated switch or hub.
Connect a PC running Wireshark on other port of the switch / hub.
Turn off the scanner, connect it to the switch /hub and turn it on.
On Wireshark you will find ARP packets sent by the scanner. Clearly you will see the IP address of the scanner.
