System Overview

HA LED

The HA (high availability) LED is for future use. The LED lights when

the router sta

rts, but otherwise remains unlit.

RESET CONFIG Button

Use the RESET CONFIG button to return the router to either the rescue

configuratio

n or the factory default configuration. Th e 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 i

t with a rescue configuration by pressing the

RESET CONFIG button. You

must have previously set the rescue configuration t hrough the J-Web interface or the

CLI. T h e rescue config uration is a previously committed, valid configuration.

CAUTION: Pressing and holding the RESET CONFIG button for 15 seconds or

more—until the co nfiguration LED blinks red—deletes all configurations on the

router, inc

luding the backup configurations and rescue configuration, and loads

and commits the factory configu ration.

You can chan

ge 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 Giga bi t Ethernet ports provide LAN connections over copper

interfaces to hubs, switches, local servers, and workstations. You can also

designate

an Ethernet port for manage ment 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

e-0/0/0

, ge-0/0/1, ge-0/0/2,andge-0/0/3.
