up the I/O module so that it is managed on the advanced management module
management network with the setting External Management over all ports
disabled.
LEDs are not lit for an I/O module
If LEDs are not lit for an I/O module, the problem could be in the power supplies,
the device itself, or the bay where the device is installed.
Problem
The LEDs for one of the I/O modules are not lit, but LEDs for other I/O modules
are lit.
Investigation
Perform these steps to resolve the problem:
1.
Verify that the ac and dc LEDs are lit for all power supplies.
v
If the dc LED is not lit on one or more power supplies, see “The dc LED is
not lit but ac LED is lit” on page 65.
v
If neither the ac LED nor the dc LED is lit for a power supply, see “The ac
and dc LEDs are not lit for multiple power supplies” on page 65.
2.
Swap the I/O module with a working I/O module of the same type. If the
problem persists with the device in the new location, contact IBM support for
possible replacement.
3.
If the LEDs on the replacement I/O module are not lit, the problem may be in
the device bay. See “Isolating component failures” on page 34.
Cannot communicate with external ports on I/O module
If a blade server cannot communicate with the external ports on an I/O module,
verify through the advanced management module that the ports are enabled.
Problem
One or more blade servers cannot communicate with the external ports on an I/O
module.
Investigation
Perform these steps to resolve the problem:
1.
Log in to the advanced management module Web interface.
2.
Make sure the external ports option is enabled in the management module Web
interface. Select
I/O Module Tasks
→
Admin/Power/Restart
to determine
whether the external ports are enabled or not.
3.
Reseat the I/O module.
4.
Replace the I/O module.
Blade server cannot communicate through CPM ports
If a blade server cannot communicate to the network through a copper pass-thru
module (CPM), verify that the pass-thru module is functioning, that the expansion
cards in the blade server are compatible, and that the network switch setting match
the settings on the copper pass-thru module.
