POST diagnostics

The mpx110 completes a series of tests as part of its POST procedure:
• Memory
• FLASH validation
• PCI device discovery
• Management Ethernet port

Heartbeat LED (green)

The Heartbeat LED indicates the status of the internal mpx110 processor and any POST error results.
Following a normal power-up, the Heartbeat LED flashes about once per second to indicate that the
mpx110 passed the POST and that the internal mpx110 processor is running. See
description of all Heartbeat LED flash codes.
