Connecting the Dial-Up Modem to the Console Port on the SRX340 Services Gateway

To connect the dial-up modem to the console port on the services gateway:

Turn off power to the services gateway.
Turn off power to the modem.
Connect one end of the Ethernet cable into the console port on the services gateway.
Connect the other end of the CAT-5e cable (Ethernet cable) into the RJ-45 to DB-9 serial port adapter.
Connect the serial port adapter to a separately purchased DB-9 socket to DB-25 plug adapter or any other adapter appropriate for your modem.
Plug the modem adapter into the DB-25 connector on the modem.
Connect the modem to your telephone network.
Turn on the power to the modem.
Power on the services gateway by pressing the Power button on the front panel. Verify that the PWR LED on the front panel turns green.
Note:
Most modems have an RS-232 DB-25 connector. You must separately purchase an adapter to connect your modem to the RJ-45 to DB-9 adapter and the Ethernet cable.
Note:
We no longer include the console cable as part of the device package. If the console cable and adapter are not included in your device package, or if you need a different type of adapter, you can order the following separately:

RJ-45 to DB-9 adapter (JNP-CBL-RJ45-DB9)

RJ-45 to USB-A adapter (JNP-CBL-RJ45-USBA)

RJ-45 to USB-C adapter (JNP-CBL-RJ45-USBC)

If you want to use RJ-45 to USB-A or RJ-45 to USB-C adapter you must have X64 (64-Bit) Virtual COM port (VCP) driver installed on your PC. See https://ftdichip.com/drivers/vcp-drivers/ to download the driver.

To remotely connect to the CLI through a dial-up modem connected to the console port on the services gateway:

Connect a modem at your remote location to a management device such as a PC or laptop computer.
Start your asynchronous terminal emulation application (such as Microsoft Windows HyperTerminal) on the PC or laptop computer.
Select the COM port to which the modem is connected (for example, COM1).
Configure the port settings :
- Bits per second—9600
- Data bits—8
- Parity—None
- Stop bits—1
- Flow control—None
In the HyperTerminal window, enter AT.
For more information on the AT commands, see the following topics:
- Installation and Upgrade Guide for Security Devices
- Network Monitoring and Troubleshooting Guide
An OK response verifies that the modem can communicate successfully with the COM port on the PC or laptop.
Dial the modem that is connected to the console port on the services gateway by entering ATDT remote-modem-number. For example, if the number of the modem connected to the console port on the services gateway is 0013033033030, enter ATDT 0013033033030.
The services gateway login prompt appears.
Log in as the root user. No password is required at initial connection, but you must assign a root password before committing any configuration settings.
