Check whether the network connection is working in general (ping the IP address of IKVM-17080 / IKVM-17160). If not, check network hardware. Is IKVM-17080 powered on? Check whether the IP address of IKVM-17080 / IKVM-17160 and all other IP related settings are correct! Also verify that all the IP infrastructure of your LAN, like routers etc., is correctly configured. Without a ping functioning, IKVM-17080 / IKVM-17160 can’t work either.
