Interpreting FC32-48 port blade LEDs
Refer to the following illustration and table to interpret the LED patterns for the FC32-48 blade. The LED
patterns will temporarily change during POST and other diagnostic tests.
1. Blade power LED
2. Blade status LED
3. Status LED for upper FC port
4. Status LED for lower FC port
The following table describes the port blade LED patterns and the recommended actions for those
patterns.
