Front Panel LEDs and Buttons
Status Description Item
Dual-function momentary switch. Its purpose is to reset the switch or to place the
switch in maintenance mode. Maintenance button 1
To reset the switch, use a pointed tool to momentarily press and release (less than
2 seconds) the Maintenance button. The switch will respond as follows:
1. All the chassis LEDs will illuminate except the System Fault LED.
2. After approximately 1 minute, the power-on self test (POST) begins, extinguishing
the Heartbeat LED.
3. When the POST is complete, the Input Power LED is illuminated and the
Heartbeat LED is flashing once per second.
Green = Switch logic circuitry is receiving the proper DC voltages. Input power LED 2
Off = Switch is in maintenance mode.
Green = Switch is in maintenance mode. Heartbeat LED 3
Blinking green (constant 1 Hz) = Switch passed the POST and the internal switch
processor is running.
2 blinks = Internal firmware failure.
3 blinks = System error.
4 blinks = Configuration file system error.
5 blinks = Over temperature.
See Heartbeat LED Blink Patterns for more information.
Amber = A fault exists in the switch firmware or hardware. Fault conditions include
POST errors and over temperature conditions. System fault LED 4
Off = Switch is operating normally.
Green = Data is being transmitted or received over the Ethernet connection. Ethernet port activity
LED 5
Off = No data being transmitted or received.
Green = Ethernet connection has been established. Ethernet port link
status LED 6
Off = No connection.
Green = A device is logged in to the port. Port logged-In LED 7
Flashing green (constant 1 Hz) = A device is logging in to the port.
Flashing green (constant 2 Hz) = The port is down, offline, or an error has occurred.
Green = Data is passing through the port. Each frame that the port transmits or
receives causes LED to illuminate for 50 milliseconds. Port activity LED 8
