Firewalls and proxy servers

Some functions of Lenovo XClarity Administrator, including management server updates, firmware updates, service and support, require access to the Internet. If you have firewalls in your network, configure the firewalls to enable XClarity Administrator management server to perform these operations. If the management server does not have direct access to the Internet, configure XClarity Administrator to use a proxy server.
