Blade server does not support SoL (as reported in the advanced
management module)
If you receive a message in the advanced management module stating that the
blade server is not supported, you may need to update firmware for the blade
server or the advanced management module.
Problem
From the SoL configuration page within the advanced management module
interface, you see an indication that the blade server does not support Serial over
LAN.
Investigation
Perform these steps to resolve the problem:
1. If you have just supplied power to the BladeCenter S chassis or you have just
reset the advanced management module, wait five minutes to ensure that the
advanced management module has completed its communication with each of
the blade servers in the BladeCenter S chassis.
2. Reseat the blade server by removing the blade server from the BladeCenter S
chassis and installing it again.
Note: Before removing the blade server, shut down the blade server operating
system; then, shut down the blade server. See the documentation that comes
with your blade servers for the procedure to shut down the operating system.
3. Install the blade server in a different blade server bay.
4. Update the blade server service processor firmware (also known as the BMC or
ISMP code).
5. Update the advanced management module firmware.
6. Suspect the system board in the blade server.
Blade server SoL status enabled but not ready (in management
module)
Use this procedure to troubleshoot SoL when the SoL is enabled but is not ready.
Problem
From the SoL configuration page with the advanced management module
interface, you see an indication that the blade server is enabled but not ready.
Investigation
Perform these steps to resolve the problem:
1. Verify that the Ethernet switch module installed in I/O module bay 1 is not a
