You can administer your eServer™ i5 server through the Hardware Management Console (HMC) with a PC by using a 5250 emulator, such as PC5250, on either a local network or an open network.
You can also choose two are shared proxy configuration or a dedicated proxy configuration on the HMC. Shared configurations enable two administrators to share the same screen. Dedicated configurations allow only one screen per administration session. If you choose to use the 5250 emulator from a remote client, you can either use Secure Sockets Layer (SSL) encryption or no encryption. SSL encryption is highly recommended.
See Scenario: HMC as a remote 5250 proxy server for more information about this configuration.
