HA LED
The HA (high availability) LED is located in the front panel near the power status LED
of the LED dashboard. The LED lights when the router starts, but otherwise remains
unlit.Table 15 on page 29 describes the HA LED.

RESET CONFIG Button
Use the RESET CONFIG button to return the router to a previous valid configuration
or to the factory default configuration, or a rescue configuration. The button is
recessed to prevent it from being pressed accidentally. For details about the RESET
CONFIG button, see “Resetting the Configuration File When the Router Is
Inaccessible” on page 160.
Built-In Gigabit Ethernet Ports
Four built-in Gigabit Ethernet ports provide LAN connections over copper interfaces
to hubs, switches, local servers, and workstations. You can also designate an Ethernet
port for management traffic. When configuring one of these ports, you use the
interface name that corresponds to the port’s location. From left to right on the front
panel, the interface names for the ports are ge-0/0/0, ge-0/0/1, ge-0/0/2, and
ge-0/0/3.
For Gigabit Ethernet port pinout information, see “Gigabit Ethernet ePIM RJ-45
Connector Pinout” on page 190.
Each port has two LEDs, a TX/RX LED on the left side and a LINK LED on the right
side. Table 16 on page 29 describes the built-in Ethernet port LEDs.
