• Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
• See Parts Listing, TD200x Machine Types 3719, 3821, 3822, and 3823 to determine which components are
customer replaceable units (CRU) and which components are field replaceable units (FRU).
• If an action step is preceded by "(Trained service technician only)," that step must be performed only by

1. Check for a server firmware
update.
Important: Some cluster
solutions require specific
code levels or coordinated
code updates. If the device

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 for information
about microprocessor
requirements).
3. (Trained service technician
only) Reseat microprocessor
n.
4. (Trained service
technician only) Replace
microprocessor n.
