v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v See Chapter 7, “Parts listing for IBM Flex System p260 and p460 Compute Nodes,” on page 97 to determine

Symptom Action
TOD_BAT The battery for the
time-of-day battery
is low or failing. Replace the battery, as described in “Removing the battery” on page 64
and “Installing the battery” on page 65.
TPMD_OV The thermal power
management
firmware has
detected that the
system is operating
without power
supply redundancy.
The maximum
power limit based on
the compute node
configuration was
reached and action
was taken to reduce
power consumption.
1. Check the Active Status log from the IBM Flex System Manager or
the Event log from the Hardware Management Console (HMC), or
the application log from the Integrated Virtualization Manager (IVM)
for any events that are related to power and resolve them. You can
access the Active Status log or the Event log from the Chassis
Manager.
2. Check the power management policy that is in place for the IBM Flex
System Enterprise Chassis. The power management policy can affect
the amount of power that is available to a compute node, which can
cause the compute node to reduce power consumption.
3. Replace the system-board and chassis assembly, as described in
“Replacing the system-board and chassis assembly” on page 83.
