Heartbeat LED blink patterns

The Heartbeat LED indicates the operational status of the mpx100/100b. When the POST completes with

no errors, the Heartbeat LED blinks at a steady rate of once per second. When the mpx100/100b is in

maintenance mode, the Heartbeat LED illuminates continuously. The blink patterns that indicate critical

errors are described in the following sections. In addition to producing a Heartbeat error blink pattern, a

critical error also illuminates the System Fault LED.

The Heartbeat LED shows an error blink p attern for the following conditions:

• 1 blink—Normal operation

• 2blinks—Notused

• 3 blinks—System error

• 4 blinks—Management por t IP address conﬂict

• 5 blinks—Over temperature

Normal heartbeat blink pattern

Ablinkpat

tern of one second ON followed by one second OFF indicates that the mpx100/100b

is operating normally (see Figure 72).
