Figure 3-9. BCN Front-Panel LEDs
The LEDs typically activate in the following order (the sequence may vary
slightly or overlap):
1. The POWER and DIAG LEDs turn on.
• When on, the POWER LED indicates that the power supply voltages are
all within normal limits. If a power module is not operational, the
POWER LED remains off. Check the power modules on the rear panel of
the BCN to determine which is not operational. The Power OK LED on
each power module remains on under normal operation. Ensure that the
power module is firmly seated within its slot. If it is, refer to Chapter 5,
“Hot-Swapping Hardware Components,” for instructions on how to
replace a power module.
• For the BCN RLC, both AC Sources (A + B) must be present before the
POWER LED will be on.
• When on, the DIAG LED indicates diagnostic testing on one or more
modules. After a successful test, the DIAG LED turns off. The DIAG
LED remains on if a diagnostic test does not end successfully for any
given slot.
2. The BOOT and RUN LEDs turn on.
• When on, the BOOT LED indicates the initialization and loading of
software by one or more modules.
• When on, the RUN LED indicates that system software is running on one
or more modules. The RUN LED remains on while the BCN is operating
normally.
