Information LEDs

The front panel of the switch module has two sets of LEDs. The OK and
switch-module error LEDs in the first column at the left of the switch module
indicate the switch-module status. The link (LINK) and activity (TX/RX) LEDs
indicate the status of the external ports. Ports 1 through 10 have a single LED that
indicates both link and activity status. Port 11 has separate link and activity LEDs.
The following illustration shows the locations of the LEDs on the switch module.
These LEDs are described in "Switch-module status LEDs" on page 25 and "Port
status LEDs" on page 25.

When POST errors are written to the system log, these errors are also written to
the BladeCenter management-module event log. If a hardware error, such as a
current fault occurs, the management module displays it. If a software error occurs,
the management module displays the Module did not complete POST message and
a post error code that indicates the test that was running when the error was
