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. See

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 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

System error blink pattern

A system error is indicated by a three-blink pattern
