Title: How to logging in to the firewall viaConsole?

Application Scenario

To access the CLI for configuration management, connect a console cable to the console port of the device and start the terminal simulation software such as SuperTerminal or SecureCRT. By default, the firewall supports console management.

Network Topology

Tool Preparation

Console cable

Model 1: Connect one end of the cable to the 9-hole DB9 connector andthe other end to the RJ45 connector.

Model 2: Connect one end of the cable to the RJ45 connector and the otherend to the USB connector.

PC with a COM port: The COM port of the PC is usually located nearthe display interface on the rear panel of the chassis. The COM port has ninepins, as shown in Figure 1-2.

If your PC does not have a COM port (such asthe laptop), the USB-to-COM cable (as shown in Figure 1-3) must be connected to the USB port toconvert it into the COM port. You can also use the USB-to-console (RJ45) cableof
Model 2 directly.

Install SecureCRT, Super Terminal, or another terminal simulationsoftware on the PC.

A PC running the Windows XP operating system is usually delivered with Super Terminal in the accessories.For a PC running Windows 7 or a later version, you need to download SuperTerminal independently.

Super Terminal is not installedin Windows Server 2003 by default. To install Super Terminal, choose Control Panel >Add/Remove Programs.

Configuration Points

(1) Prepare a configuration cableand a PC that can be connected to a configuration cable. (For details, see Tool Preparation.)

(2) Connect the configuration cable.

Connect the RJ45 connector of theconfiguration cable to the console port of the device and the other end to theCOM port of the PC.

(3) Run the terminal simulation software to log in to the device.

Procedure

(1) Connect the configurationcable.

a Insert the RJ45 connector ofthe console cable to the console port of the device (as shown in the followingfigure).

b Insert the DB9 connector on theother end of the console cable to the 9-pin COM port of the PC.

(2) Run the terminal simulationsoftware after the configuration cable is connected.

Note:

This section uses SecureCRT as an example.For details about other programs, see the corresponding operation manual.

(3) View identified COM ports onthe PC.

Note:

If a PC has only one COM port, it isdisplayed as COM1 by default. In this case, skip this step.

a Right-clickThis PC, choose Manage >Device Manager, and view COM ports under Ports(COM & LPT).

b Run the SecureCRT software. The QuickConnect dialog box is displayed automatically. (If the dialog box is notdisplayed, click in the menu bar.) In the dialog box, set theconnection parameters and click Connect.The following table describes the connection parameters that you need to set.

Parameter	Value
Protocol	Serial
Port	COM port of the PC identified in the previous step
Baud rate	115200
RTC/CTS	Deselect

Note:

It takes acertain period of time to complete system initialization after the device ispowered on and started. You are advised to wait until the system is readybefore running CLI commands.

Caution:

If you fail to access the CLI, checkthe configurations as follows:

Check whether the configuration cable is connected to the console port.

Check whether the baud rate is set to 115200 for the terminal simulation connection.

If the preceding configurations are correct, replace the PC, configuration cable,and terminal login software.
