Step 5: Set Up Access to the CTP Device

Console Access

Before you power on the device, you must set up a management console. You use the console to communicate with the device during the power-on process, to set an IP address, and to manage the device using the command-line interface (CLI).

You can monitor and manage the device through either of these methods:

  • Console terminal—You can connect a console terminal (PC, Macintosh, or UNIX workstation) directly to the CONSOLE terminal port. When you connect a console directly to the device, you can configure the device without an IP address. To communicate with the device, 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.

    You can connect a console to the COM2 port on the PP310 and PP332 processors. On the PP833 processor, a console is connected using the supplied USB-to-DB9 cable (p/n 720-071594), in which the DB-9 connector has the same pinout as a standard RS-232 DTE port. When the USB-to-DB9 cable is used in conjunction with the DB-9 adapter labelled “p/n 450-071855”, the available RJ-45 console pinout will be the same as the console connection on the RTM of PP332/PP310 processor.

    Alternatively, if the DB-9 adapter from the bag labelled “p/n 720-056657” is used instead of “p/n 450-071855”, the available RJ-45 console pinout will be similar to the CTP150 console port (and other Juniper routers). To connect the PP833 processor with the DB-9 male serial port of a PC, additionally connect a straight RJ-45 cable with the DB-9 adapter from the bag labelled “p/n 720-056657”. The other end of the RJ-45 cable connects to the DB-9 adapter from the bag labelled “p/n 720-014126”. Then, you can connect the PC’s DB-9 male connector with the DB-9 adapter “p/n 720-014126”.

    Refer to the CTP2000 Series Console Cable Pinouts section in CTP2000 Series Hardware Guide for information about the pinouts of PP310/PP332 and PP833 processor console cables, USB-to-DB9 cable, and DB9-to-RJ45 adapters.

  • Remote console—Connect 10/100Base-T to the CONSOLE port to an Ethernet network, and run SSH from a remote console.

For initial access to the device, you need to physically connect your console directly to the device's RJ-45 port. Through this connection you use the CLI to set an IP address on the device. After you configure the IP address, you can access the device remotely (for example, through SSH).

Direct Access

When you connect a console directly to the device, use the CONSOLE port on the RJ-45 connector. To connect a console directly to the device:

  1. Connect the male RJ-45 connector to the CONSOLE port.
  2. Connect the crossover adapter connector to your PC's serial port.
  3. Power on the device.

    When you power on the device, the CLI appears on your console's screen..

    Note: Direct access through the CONSOLE serial port enables you to monitor the device while it boots.

HyperTerminal Access

If your console uses a version of Microsoft Windows (such as Windows XP or Windows NT 4.0) that supports the HyperTerminal application, you can access the device through HyperTerminal.

  1. Click the Start button and select Programs > Accessories > Communications > HyperTerminal.
  2. In the HyperTerminal window, select HyperTerminal.
  3. In the Connection Description dialog box, enter a name for your device in the Name field.
  4. Select any icon to represent your terminal emulation, and click OK.
  5. In the Connect To dialog box, in the Connect using field, select the appropriate COM port to use (for example, COM1), and click OK.
  6. In the COM1 Properties dialog box, select the following settings:
    • Bits per second: 9600
    • Data bits: 8
    • Parity: None
    • Stop bits: 1
    • Flow control: Xon/Xoff
  7. Click OK.

SSH Access

When you have configured an IP address for the device, you can run SSH from a host to access the device through its Ethernet port. To connect the Ethernet port to the network:

  1. Connect an Ethernet cable (RJ-45) to the device's 10/100Base-T (RJ-45) port on the system processor.
  2. Connect the other end of the cable to the appropriate Ethernet network for an out-of-band connection.

Caution: Do not change the IP address for the Ethernet interface that you are using to communicate with the device. If you change the address, you will lose the SSH session.
