— If the DC OK LED is on at startup and fans are operating, but the system shuts down after
two minutes, there is a problem with the fan tray. Proceed to the section "Troubleshooting
the Cooling Subsystem."
•
When you turn on the system power, the LEDs on the RP, which is located in the top processor
slot (see Figure 1-3) should go on and off as follows:
— The RP boot error LED goes on and stays on for 1 to 2 seconds when the system boot
sequence is initialized, but it should otherwise remain off. If the system software is unable
to start up, this LED will go on and stay on.
— The RP normal LED goes on after the system has completed a successful boot to indicate
normal system operation. This LED should remain on during system operation.
— The halt CPU LED should always remain off. This LED goes on only if the system detects
a processor hardware failure.
If the normal LED on the RP does not go on, or if either the boot error or halt CPU LED goes on
and stays on, proceed to the section "Troubleshooting the Cooling Subsystem."
•
The enabled LED on the SP (or SSP) and on each interface processor goes on when the RP has
completed initialization of the interface processor or SP (or SSP) for operation. This LED
indicates that the SP (or SSP) or interface processor is receiving power and has been recognized
by the RP; it does not indicate the state of the individual interfaces. It does, however, indicate that
an interface processor or SP (or SSP) contains a valid microcode version. If an enabled LED fails
to go on, proceed to the section "Troubleshooting the Interface Processors."
While the system is starting up and initializing the individual interface processors, the status
Note
LEDs on the interface processors will flash on and off or light intermittently; this is normal behavior.
The LEDs do not indicate the true status of the interfaces until the system has initialized the interface
processors and you have enabled the individual interfaces.
When the LEDs indicate that the system has initialized successfully, the system banner (similar to
the following example) should be displayed on the console screen.
