Using The Integrated Management Module - IBM System x3850 X5 Implementation Manual

This precaution will eliminate the possibility of a single breaker or circuit fault from taking
down the entire server.
Think of the power supplies in your server as shock absorbers in your car. They are designed
to absorb and overcome a wide variety of power conditions that can occur from an electric
utility company, but like shock absorbers on a car, they will eventually begin to fail when fed a
steady diet of unstable power. The time of their failure will most likely not coincide with a
planned maintenance panel. For this reason, ensure that the two halves of the power supplies
are plugged into two separate UPS sources to filter out all of the moderate to severe power
fluctuations that occur.

6.8 Using the Integrated Management Module

For any successful server implementation, there must be provisions set aside to provide
access to perform troubleshooting or routine maintenance. The x3850 X5 ships standard with
the Integrated Management Module (IMM). The IMM is a separate, independent operating
environment that starts to activate and remains active while the server is plugged into a good
ac power source. The IMM monitors the hardware components of the server and the
environment on which the server operates, looking for a potential hardware fault.
Part of the information that is stored in the IMM can be accessed with F1-Setup by selecting
System Settings  Integrated Management Module. Figure 6-26 show the first panel of
the IMM configuration panel.

Tip: If you have a server but you do not know the logon credentials, you can reset it by
going to the panel that is shown in Figure 6-26, from F1-Setup, and then restore the IMM
configuration to the factory defaults by selecting Reset IMM to Defaults.
