Power module status LEDs
Power module status LED varies by MPU model.
• If the MPU provides one set of LEDs (OK and FAIL) to indicate the status of the power modules,
see
Table 39 for the LED description.
• If the MPU provides multiple LEDs with numbers (for example, PWR1 and PWR2), each LED
corresponds to a pluggable power module with the same number (the power module number is
marked on the chassis). See Table 40 for the LED description.
• If the MPU provides only one power status LED (PWR), see Table 41 for the LED description.
