Even though the network interfaces into the service processors are encrypted for the Secure Sockets
v
Layer (SSL) Protocol and password-protected, having a separate dedicated network can provide a
higher level of security for these interfaces.
v An open network interface would typically be used for the network connection between the HMC and
the logical partitions on the managed systems, for the HMC-to-logical partition communications. You
can also use this open network interface to manage the HMC remotely.
v Optionally, you can use a third interface to connect to logical partitions and manage the HMC
remotely. This interface can also be used as a separate HMC connection to different groups of logical
partitions. For example, you might want to have an administrative LAN that is separate from the LAN
on which all the usual business transactions are running. Remote administrators could access HMCs
and other managed units using this method. Sometimes the logical partitions are in different network
security domains, perhaps behind a firewall, and you might want to have different HMC network
connections into each of those two domains.
Web browser requirements for HMC
The Hardware Management Console (HMC) is supported by Microsoft Internet Explorer (IE) version 6.0
and 7.0, Firefox version 1.5.0.7 and 2.0.
If your browser is configured to use an Internet proxy, a local IP addresses should be included in the
exception list. Consult your network administrator for more information on the exception list. If you still
need to use the proxy to get to the HMC, enable Use HTTP 1.1 through proxy connections under the
Advanced tab in your Internet Options window.
