Firewalls and proxy servers
The server warranty status function requires access to the Internet. If you have firewalls in your network, configure the firewalls to allow Lenovo SDI Management Platform to access the Internet. If Lenovo SDI Management Platform does not have direct access to the Internet, configure it to use a proxy server.
Firewalls
Ensure that the following DNS names and ports are open on the firewall.
IP addresses are subject to change. Use DNS names when possible.
| DNS name | IPv4 address | IPv6 address | Port | Protocol |
