One or more port blades have either
shut down or failed POST as
indicated by the error log. Blades might be overheated. Enter the sensorShow command to check the
internal temperature readings. If components are
overheating, shut down port blades as necessary to
return the temperature readings to the operating
ranges.
Also try moving the blades in the chassis since it is
possible that airflow might not be adequate to cool
everything in certain configurations.
Blades might be faulty. Enter the slotShow command to determine status.
For more information, enter the diagDisablePost
command; then, use the slotPowerOff [slot number]
and slotPowerOn [slot number] command. Resolve
the source of the problem or replace the blade as
required.
Pins on the blade or the backplane might be
damaged. Remove the blade from the chassis and inspect the
pins on the blade and on the backplane inside the
slot. Do not reinstall if the pins on either component
are damaged, as this could damage pins on other
components. Replace the components as required.
An individual component is not
operating as expected. Component may not have power or may not
be firmly seated. Ensure that the component is receiving power
(power LED should be on) and the component is
firmly seated.
Pins on the component or the backplane
might be damaged. Remove the component from the chassis and
inspect the pins on the blade and inside the chassis.
Do not reinstall if the pins on either component are
damaged, as this could damage pins on other
components. Replace parts as required.
The component might have failed. Enter the tempshow and sensorShow command to
determine the component status. If the component
is a CP blade or port blade, enter the slotShow
command to determine the status. Replace the
component as necessary
