About this task
v Follow the suggested actions in the order in which they are listed in the Action column until the problem is

v See Chapter 4, “Parts listing, Types 7145, 7146, 7143, and 7191,” on page 81 to determine which components are
customer replaceable units (CRU) and which components are field replaceable units (FRU).
v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.

1. Make sure the embedded hypervisor device is selected in the boot menu (in
the Setup utility and in Select Boot Device).
2. If the embedded hypervisor is on an internal flash memory device, make sure
that the internal flash memory device is seated in the connector correctly (see
“Removing the internal flash memory” on page 140 and “Replacing the
internal flash memory” on page 141).
3. See the documentation that comes with the embedded hypervisor for setup
and configuration information.
