The ALARM LED is located to the le ft of the power button on the front panel (see Figure 5). The yellow (amber) LED l igh ts to indicate a critical condition that can result in a system s h utdown or a less severe condition that requires mo nitoring or maintenance. When the co nd ition is corrected, the light turns off.

NOTE: The ALARM LED on the Services Router lights yellow wh eth er the alarm condition is major (red) or minor (yellow).

To deactivate alarms, you must clear the condition that caused the alarm. For a list of alarms that can o ccu r on the router, see “Chassis Alarm Conditions” on page 188.

Power Button and POWER LED

The power button is located on the left side of the front panel (see Figure 5). You can use the power button to power the Services Router on and off. When you power on the router, the Routing Engine boots as the power supply completes its startup sequence.

The

quickly released, and the router is gracefully shutting down.

After the router is powered o n, status indicators—such as LEDs on the front panel and

show chassis command output—can take up to 60 seconds

to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

If you need to power off the router after the Routing E ng ine finishes booting, use the J-Web interface or the CLI to halt the Services Router first. For instructions, see t he J-series Services Router Administration Guide.

To power off a Services Router, you can shut it down in one of the following ways:

Graceful shutdown—Press and release the power button. The router begins gracefully shutting down the operating system and then powers itself off.

Immediate shutdown—Press the power button and hold it for more than 5 seconds. The router immediately powers itself off without shutting down the operating system.

CONFIG Button

Use the CONFIG button to return the router to either the rescue configuration or the factory default configuration. The prevent it from being pressed accidentally.

The

CONFIG button performs two recovery operations:

Rescue—Press and release the CONFIG button to load and commit the rescue configuration, if you have set it. To set the rescue configuration, see the J-series Services Router Basic LAN and WAN Access Configuration Guide.

Clear—Press and hold the CONFIG button for 1 5 seconds or more, until the configuration LED blinks red to indicate the clear operation is in progress. The clear operation d eletes all configurations on the router (including the rescue configuration and backup configurations) and loads and commits the factory configuration.

The Rout

Each J-series Services Router runs the JUNOS Internet software on its general-purpose processors. Designed for the large production networks typically

ted by Internet service providers (ISPs), the JUNOS software includes

suppor processes for Internet Protocol (IP) routing and for managing interfaces, networks, and the router chassis.

The JUNOS Internet software runs on the Routing Engine. The Routing Engine

l coordinates communication among the JUNOS so ftware processes and

kerne provides a link to the Packet Forwarding Engine.

With the J-Web interface and the command-line interface (CLI) to the JUNOS software, you configure the routing protocols that run on the Services Router and set

operties of its network interfaces. After activating a software configuration,

the pr use either user interface to monitor the protocol traffic passing through the router, manage operations, and diagnose protocol and network connectivity problems.

The user interfaces on a Serv ices Router interact with the management process to execute co mmands and store and retrieve information from the confi guration database. The user interfaces operate as clients that communicate with the JUNOS Internet software through an application programming interface (API).

The following primary user interfaces are shipped with the router:

J-Web graphical user interface—Includes quick configuration capa bilities for performing the minimum required steps to enable a feature, plus a built-in configuration editor with access to the entire configuration hierarchy to fully

Physical Int

A Physical Interface Module (PIM) is a network interface card that is installed on a J-series Services Router, to provide physical connections to a LAN or a WAN. The PIM receive to the network. Each PIM is equipped with a dedicated network processor tha t forwards incoming data packets to the Routing Engine, and receives outgoing data packets fro and line-speed signaling for its medium type.

PIMs are removable and insertable only when the Services Router is powered off. You can install a PIM into one of the six slots in the router chassis. If a slot is not occupied by a PIM, a PIM blank panel must be installed to shield the empty slot and to allow cooling air to circulate properly through the router.

These Services Routers support the type s of PIMs summarized in Table 27 and described in the following sections:

CLI Configuration Mode

To configure the Services Router, including system parameters, routing protocols, interfaces, network management, and user access, you must enter config uration mode. In conf router, load a text (ASC II ) file that contains the router configuration, activate a configuration, and save the configuration to a text file.

Command Completion

You do not always have to remember or type the full command or option name for the CLI to recognize it. To display all possible command or option completions, type the partial command followed immediately by a question mark (?).

To complete a command or option that you have partially typed, press Tab or Spacebar. If the partially typed letters uniquely identify a command, the complete command name appears. Otherwise, a message indicates that your entry is ambiguous or invalid. Possible command completions are displayed if your entry is amb iguous.

You can also use command completion on filenames and usernames. To display all possible values, type one or more characters followed immediately by a question mark. To complete these partial entries, press Tab only. Pressing Spacebar does not work.

Online Help

The CLI provides context-sensitive help at every level of the command hierarchy. The help information tells you which commands are available at the current level in the hierarchy and provides a brief d escription of eac h.
