Table 26. Troubleshooting (continued)
None of the LEDs on an
individual component are
on. Component might not be seated
correctly. Ensure that the SAN768B-2 has power and
component is firmly seated. If problem continues,
run the
sensorShow command to determine
component status. If component is a CP blade or
port blade, enter the
slotShow command to
determine status.
Component might have failed. Replace component as necessary.
CP blades are failing over
frequently. A third-party application has a
memory leak. Check application for memory leaks.
There is excessive serial port
activity. Ensure that serial port activity remains below
specified amount.
CP blade is attached to an
Ethernet with high traffic loads. Ensure that Ethernet traffic remains below
specified amount.
Chassis is overheated. Enter the tempShow and sensorShow commands
to check internal temperature. If components are
overheating, shut down the port blades as
necessary to return the temperature to operating
range.
One or more port or
application 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 the port blades as
necessary to return the temperature readings to the
operating ranges.
Blades might be faulty. Enter the slotShow command to determine status.
For more information, enter the diagDisablePost
command; then, the slotPowerOff [slot number]
and slotPowerOn [slot number] commands.
Resolve the source of the problem or replace the
blade as required.
Pins on the blade or on the
backplane (inside the slot) might
be damaged. Remove blade from chassis and inspect pins on
blade and on backplane inside slot. Do not
reinstall if pins on either component are visibly
damaged, as this could damage pins on other
component. Replace components as required.
An individual component
is not operating as
expected. Component may not have power
or may not be firmly seated. Ensure component is receiving power (power LED
should be on) and component is firmly seated.
Pins on the component or the
backplane might be damaged. Remove component from chassis and inspect pins
on blade and inside chassis. Do not reinstall if pins
on either component are visibly damaged, as this
could damage pins on other component. Replace
parts as required.
The component might have failed. Enter the tempShow and sensorShow commands
to determine component status. If component is a
CP blade or port blade, enter the
slotShow
command to determine the status. Replace the
component as necessary.
