2. Inspect the AC power source. Is the power source delivering the proper voltage?
• If yes, proceed to the next step.
• If not, make the necessary repairs. If the problem persists, proceed to the next step.
3. Replace the MPX200 blade.

System Fault LED is illuminated

The System Fault LED is illuminated when a fault exists in the MPX200 firmware or hardware. If the
System Fault LED is illuminated, check the Heartbeat LED for an error blink pattern and take the
necessary actions. For more information, see

Fibre Channel Port LEDs

• The top LED (2 Gb/s) indicates activity (data) is passing through the port at 2 Gb/s speed.
• The middle LED (4 Gb/s) indicates activity (data) is passing through the port at 4 Gb/s speed.
• The bottom LED (8 Gb/s) indicates activity (data) is passing through the port at 8 Gb/s speed.
• When all three LEDs are blinking, the port is not operational.

Power-on self-test (POST) diagnostics

The MPX200 performs a series of tests as part of its power-on procedure. The POST diagnostic program
performs the following tests:
• Memory
• Flash validation
• PCI device discovery
• Management Ethernet port

Heartbeat LED blink patterns

The Heartbeat LED indicates the operational status of the MPX200. When the POST completes with
no errors, the Heartbeat LED blinks at a steady rate of once per second. When the MPX200 is in
maintenance mode, the Heartbeat LED blinks continuously. The blink patterns that indicate critical
errors are described in the following sections. In addition to producing a Heartbeat LED blink pattern,
a critical error also illuminates the System Fault LED. The Heartbeat LED shows a blink pattern for the
following conditions:
• 1 blink—Normal operation
• 2 blinks—Not used
• 3 blinks—System error
• 4 blinks—Management port IP address conflict
• 5 blinks—Over temperature
Normal blink pattern
A blink pattern of one second ON followed by one second OFF indicates that the MPX200 is operating
normally (Figure
154 Diagnostics and troubleshooting
106).
