Action
1. Verify that the server has DC power.
2. Make sure that you are using the correct log-in information. The fields are case
sensitive.
3. Check with the system administrator for the correct login parameters and if
parameters can log-in to the IMM, then do the following:
a. If the IMM is proven accessible (by system administrator), verify the login
information.
b. If the IMM is not accessible by system administrator, reset the IMM to
defaults through the Setup utility.
c. Retry the login. If IMM is still not accessible, replace the standard I/O book
(see"Removing the standard I/O book" on page 221 and "Replacing the
standard I/O book" on page 222).
1. Verify that the server has DC power.
2. Make sure that the server IMM has acquired an IP address in the Setup utility.
Note: If the IMM recently lost connection to the DCHP server, you must reset
the IMM so that a new IP address can be acquired.
3. Check the IBM Support web site for any firmware updates that might apply to
this problem (see http://www.ibm.com/supportportal/). Read the release
notes for the firmware update to determine the issues that the update
addresses.
Action
If the part is a CRU, replace it. If the part is a FRU, the part must be replaced by a
trained service technician (see Chapter 6, "Removing and replacing components,"
on page 217 to determine whether the part is a CRU or a FRU).
