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.
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 configuration 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 “RJ-45 Connector Pinout
for Gigabit Ethernet Ports” on page 195.
Each port has two LEDs, a TX/RX LED on the left side and a LINK LED on the
right side. Table 10 describes the built-in Ethernet port LEDs.
