Device
Ethernet switch-module log
reports elapsed time, not time
of day.
Ethernet disconnect notice
will not appear when
running Windows 2000.
The default IP address set by
the Ethernet switch module
does not match the one
assigned by the management
module.
Updating the Ethernet switch
module configuration
through the management
module does not save the
switch NVRAM.
Keyboard problems
The keyboard is very slow
when using an operating
system that does not have
USB drivers.

BladeCenter T Type 8267: Hardware Maintenance Manual and Troubleshooting Guide
Suggested action
The timestamp on entries in the Ethernet switch module log uses elapsed time (since
last switch restart). The timestamp on entries restarts from 0 each time the switch is
restarted, although the entries do remain in order of occurrence.
If an Ethernet cable is accidentally removed from the back of the BladeCenter T unit,
the small red X (disconnect notice) that normally would appear to indicate that the
cable was disconnected will not appear in the bottom right of the screen. The
disconnect notice does not appear because the blade server Ethernet controller
connects to the Ethernet switch module through integrated circuitry inside the
BladeCenter T unit.
When troubleshooting Ethernet-related problems, make sure that the Ethernet cables
on the back of the BladeCenter T unit are connected properly.

When you use the management-module Web interface to update the Ethernet switch
module configuration, the management module firmware writes its settings for the
switch module only to the management module NVRAM; it does not write its
settings for the switch module to the switch-module NVRAM.
If the switch module restarts when the management module is not able to apply the
IP address it has in NVRAM for the switch module, the switch module will use
whatever IP address it has in its own NVRAM. If the two IP addresses are not the
same, you might not be able to manage the Ethernet switch module any more.
The management module cannot apply the switch IP address from its NVRAM if:
v The management module is restarting
v The management module has failed
v The management module has been removed from the unit.

When you are running an operating system that does not have USB drivers, such as
in the following instances, the keyboard responds very slowly.
1. Run the blade server integrated diagnostics
2. Run a BIOS update diskette on a blade server
3. Update the diagnostics on a blade server
4. Run the Broadcom firmware CD for a blade server
