Juniper Networks J2320 manual Ha Led

Chapter 2: System Overview

HA LED

The HA (high availability) LED is for future use. The LED lights when the router starts, but otherwise remains unlit.

RESET CONFIG Button

Use the RESET CONFIG button to return the router to either the rescue configuration or the factory default configuration. The button is recessed to prevent it from being pressed accidentally. To press this button insert a small probe (such as a straightened paper clip) into the pinhole on the front panel (see Figure 19 on page 32).

For example, if someone inadvertently commits a configuration that denies management access to a Services Router, you can delete the invalid configuration and replace it with a rescue configuration by pressing the RESET CONFIG button. You must have previously set the rescue configuration through the J-Web interface or the CLI. The rescue configuration is a previously committed, valid configuration.

CAUTION: Pressing and holding the RESET CONFIG button for 15 seconds or more—until the STATUS LED blinks red—deletes all configurations on the router, including the backup configurations and rescue configuration, and loads and commits the factory configuration.

You can change the default behavior of the RESET CONFIG button. For more information, see the J-series Services Router Basic LAN and WAN Access Configuration Guide.

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 236.

Each port has two LEDs, a TX/RX LED on the left side and a LINK LED on the right side. Table 15 on page 35 describes the built-in Ethernet port LEDs.
