Configuration file system error LED flash pattern
A configuration file system error flash pattern is four flashes per second followed by a 2-second pause, as
shown in the following illustration. The four-flash error pattern indicates that a configuration file system error
has occurred.
Switch module fault LED flash pattern
The amber Switch Fault LED is lit to indicate one or more of the following conditions:
• POST failure
• Over temperature condition
• Port operational test failure. See “Port fault LED flash patterns” on page 124 for information about port
operational tests.
If the Switch Fault LED is lit for reasons other than a port operational test failure, take the Fibre Channel
switch module offline and contact your technical support representative.
Switch module OK LED
The green OK LED is lit to indicate that the switch module has completed POST diagnostics without errors. If
this LED is not lit when you turn on the SBCE unit or turns off during operation, remove the switch module
and inspect the connector for damage.
Port logged-in LED flash patterns
The Port Logged-in LED has the following flash patterns:
• Logged in - The logged-in LED is lit continuously.
• Logging in - The logged-in LED flashes at once per second as shown in the following illustration.
• Set beacon - Enables or disables the flashing of the Port Logged-in LEDs according to [state]. For
information about the set beacon command, see “Set command” on page 27.
• Error - The logged-in LED flashes at twice per second as shown in the following illustration.
A logged-in LED error indication is often the result of E_Port isolation. Table 33 on page 124 describes the
causes and remedies for E_Port isolation conditions. An isolated E_Port is indicated by a red link in the
Topology window. See “Timeout values” on page 107, “Domain ID and Domain ID Lock” on page 106, and
“Zoning a fabric” on page 88 for information about how to set IDs, timeout values, and edit zoning.
