[. . . ] 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. Managing your router includes both configuring and monitoring 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. You can use any terminal emulation program, such as HyperTerminal. 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. In the HyperTerminal window, select HyperTerminal. In the Connection Description window, enter a name for your router (for example, erx1400) in the Name field. Select any icon to represent your terminal emulation, and click OK. In the Connect To dialog box, in the Connect using field, select the appropriate COM port to use (for example, COM1), and click OK. In the COM1 Properties window, select the following settings: Bits per second: 9600 Data bits: 8 Parity: None Stop bits: 1 Flow control: Xon/Xoff 7. Click OK. Connecting Directly to the Router When you connect a console directly to the system, use a cable appropriate for your terminal connector. The cable must have a female DB-9 connector to attach to the RS-232 port on the system. The console port is considered a data terminal equipment interface (DTE). Direct connection to a terminal or PC (which also have DTE interfaces) requires a crossover cable. [. . . ] ID stickers are usually applied near the ejector. Fan trays are not listed in the show hardware command output. ERX7xx model and ERX14xx model fan trays have stickers on the faceplate. For the ERX310 router, you must remove the fan tray to view the serial number ID sticker. 140 Locating Component Serial Numbers Appendix D: Contacting Customer Support and Returning Hardware Figure 59: Representative Module Serial Number ID Label Information You Might Need to Supply to JTAC When requesting technical support from the JTAC by phone, be prepared to provide the following information: Priority level Indication of what activity was being performed on the router when the problem occurred Problem detail and configuration data, obtained by these commands: show version show hardware show environment show configuration When a new request for technical support is submitted, the JTAC engineer: 1.
