1. Check for a server firmware
update.
Important: Some cluster
solutions require specific code
levels or coordinated code
updates. If the device is part
of a cluster solution, verify
that the latest level of code
is supported for the cluster
solution before you update the
code.
2. Make sure that the installed
microprocessors are
compatible with each
other (see "Installing a
microprocessor and heat sink"
on page 189 for information
about microprocessor
requirements).
3. (Trained service technician
only) Reseat microprocessor n.
4. (Trained service technician
only) Replace microprocessor
n.
