Information LEDs

The front panel of the switch has two sets of LEDs. The OK and switch error LEDs
indicate the switch status. The link (LINK) and activity (TX/RX) LEDs indicate the
status of the external ports.
Notes:
1. A yellow LED on the IBM Flex System chassis is lit when a system error or
2. During POST, the Power LED continuously flashes. Additionally, all of the status
Any errors that are detected during POST are written to the system log. For
information about the command to read the system log, see the IBM Command
Reference for the switch.
When POST errors are written to the system log, these errors are also written to
the IBM Flex System management-module event log. If a hardware error, such as a
current fault occurs, the management module displays it. If a firmware 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
detected.
Note: You can also use the management module to make sure that the switch is
