5.1.6 IMM2 communications troubleshooting

The Integrated Management Module User Guide is an excellent guide to help you with every
aspect of troubleshooting the IMM. Download the guide from this website:

Most communication errors are due to network switch configuration options, such as blocked
ports or VLAN mismatches. The following procedure shows you how to determine this type of
problem by connecting directly to the IMM2 port with a laptop and Ethernet patch cable,
pinging, and then starting a web session.
If you can ping the IMM, you have a good direct network link. If the web session fails, go
through the following steps:
1. Try another web browser (see supported browsers 5.1.1, "IMM2 virtual presence" on
page 132).
2. Directly access the Integrated Management Module configuration panel and reset the
IMM2 in F1-Setup by selecting System Settings  Integrated Management Module 
Reset IMM. You will have to wait about 5 minutes for the IMM2 to complete enough of its
reboot to allow you to ping it. This IMM2 reset will have no impact on the operating system
that is running on the server.
3. Try clearing the web browser cache.
4. Load the factory default settings back on the IMM2 through F1-Setup by selecting System
Settings Integrated Management Module Reset IMM2 to Defaults. The IMM2 will
need to be reset again after the defaults are loaded.
5. Contact IBM support.
