2.
Check all LEDs.
a.
Check the LEDs on the I/O module to ensure that the OK LED is lit and
that the Error LED is not lit.
1)
If the OK LED is not lit, reseat the module and wait 60 seconds for the
OK LED to light.
2)
Check the advanced management module event log for I/O module
power errors.
b.
Check all LEDs for the BladeCenter S chassis. Verify that the power LED is
lit and that the over-temperature, information, and system-error LEDs are
not lit.
c.
Check the LEDs on the advanced management module to ensure there are
no error conditions.
3.
Log in to the advanced management module and check any problems.
a.
Check the System Status page for any messages.
b.
Check the advanced management module hardware Vital Product Data
(VPD) to validate the VPD for the I/O module. If the I/O module is a
switch module and it is located in bay 3 or 4, the type of expansion card
option installed on the blade server must match the I/O module type. For
example, if the I/O module is an SAS connectivity module, a SAS
expansion card option in each blade server that will access the integrated
shared storage.
c.
Check the advanced management module firmware VPD to ensure that it is
compatible with the I/O module firmware. Update the firmware if needed.
d.
Check the advanced management module event log to determine whether
there are power recovery event or service processor communications errors.
If there are errors for multiple BladeCenter S chassis components, the
problem may be related to the chassis. See “Isolating component failures”
on page 34.
4.
Use the advanced management module to restart the I/O module.
5.
Verify that the module bay is functioning
a.
If you have another functioning I/O module, replace the I/O module that
will not power on with the functioning I/O module. If the replacement
module works in the bay, the original I/O module needs to be replaced.
Note:
The module that you use as a replacement must be the same type of
I/O module as the original. For example, you can only replace an Ethernet
switch module with another Ethernet switch module.
b.
If you do not have another functioning I/O module, move the I/O module
to another I/O bay in a different chassis (in the same bay).
1)
If the I/O module powers up, the problem may be related to the
chassis. See “Isolating component failures” on page 34.
2)
If the I/O module does not power up, replace it.
c.
If you have neither a functioning I/O module nor another chassis:
1)
See “Isolating component failures” on page 34. Keep in mind that this
will require bringing down all components in the chassis.
2)
Replace the I/O module. However, if the problem is related to the
chassis, it will persist even if you replace the I/O module.
6.
Check the I/O module settings. In most cases, unless you are very familiar
with the setup of your company's internal server network, you will want to set
