[. . . ] See Table 11 on page 101 in "Troubleshooting" on page 95 for LED status explanations. When the prompt appears on the system console, the system is in User Exec mode and is ready to be configured: host1> 6. Enter the enable command to access Privileged Exec mode: host1>enable host1# In Privileged Exec mode you can begin to configure the system. See JUNOSe System Basics Configuration Guide, Chapter 2, Command-Line Interface for more information. Initialization Sequence Each line module is initialized independently. As a result, the CLI on the SRP module can become available before the line modules have completed initialization. Commands relating to a line module might fail if the module has not completed initialization. Do not enter commands for a line module until its state is listed as online. Status LEDs Upon initial power-up, the components of the router run boot code, go through a series of self diagnostic tests, and synchronize with each other. When the tests are complete, use the LEDs on each module to determine the status of the router. Observe the line module and SRP module LEDs in the front, and the I/O line module and SRP I/O module LEDs in the rear. See "Troubleshooting" on page 95 for information on the system's LEDs. 66 Status LEDs Chapter 6: Powering Up ERX Routers Powering Down If you need to power down or remove the SRP module, first enter the halt command to temporarily suspend the system's operation. See JUNOSe System Basics Configuration Guide, Chapter 5, Managing the System for more information. CAUTION: If you do not use the halt command before removing or powering down an SRP module, the system's NVS card might become corrupted. If you shut down the system improperly, it runs an investigation of the file allocation table (FAT) the next time it reboots. The Next Step If you have problems powering up the system, see "Troubleshooting" on page 95 for help. If the system boots properly, see "Accessing ERX Routers" on page 69. Powering Down 67 ERX 11. 1. x Hardware Guide 68 The Next Step Chapter 7 Accessing ERX Routers This chapter discusses how to access the system to manage it. For basic information on the management of the system, see JUNOSe System Basics Configuration Guide, Chapter 5, Managing the System. This chapter contains the following sections: Setting Up Management Access on page 69 Console Port Setup on page 69 Telnet Setup on page 72 SNMP on page 73 The Next Step on page 73 Setting Up Management Access Before you power up the system, you must set up a management console. (See "Connecting to a Console Terminal" on page 52. ) You use the console to communicate with the system during the power-up process, set an IP address, and manage the system using the command-line interface (CLI). You can manage and monitor the router through either of these methods: Console terminal--Connect a console (PC, Macintosh, or UNIX workstation) directly to the system's RS-232 serial port. Remote console--Connect the 10/100Base-T port on the SRP I/O module to an Ethernet network, and run Telnet from a remote console. For initial access to the system, you need to physically connect your console directly to the system's RS-232 port. Through this connection you can use the CLI to set an IP address on the system. After you configure the IP address, you can access the system remotely (for example, via Telnet). Console Port Setup You can connect a console terminal (PC, Macintosh, or UNIX workstation) directly to the SRP I/O module via the RS-232 terminal port. When you connect a console directly to the system, you can configure the system without an IP address. Setting Up Management Access 69 ERX 11. 1. x Hardware Guide To communicate with the system, you must have a terminal emulation program running on your PC or Macintosh. A UNIX workstation can use the emulator TIP. Using HyperTerminal If your console uses a version of Microsoft Windows (such as Windows 95 or Windows NT 4. 0) that supports the HyperTerminal application, you can access the system via HyperTerminal. 1. 6. Click the Start button and select Programs, Accessories, and HyperTerminal.
