ClearPass Serial Connection

    Posted 5 days ago
    Good afternoon 

    Question: Is there a part number for the serial ClearPass cable? We do not have the serial cable that came in the box. We have tried multiple null model cables brand with no luck getting console. Any suggestion using a third-party cable? 

    Another option is to use a serial to rj45 converter so I can plug the C3000 appliance to the open gear console server. 

    Thank you in advance, 

    Configuring the Policy Manager Hardware Appliance

    The initial setup dialog starts when you connect a terminal, PC, or laptop running a terminal emulation program to the Serial port on the Policy Manager hardware appliance.

    To configure the Policy Manager hardware appliance:

    1. Connect the Serial port.

    a. Connect the Serial port to a terminal using a null modem cable.

    b. Power on the hardware appliance.

    The hardware appliance is now available for configuration.

    2. Configure the Serial port.

    Bit Rate: 9600

    Data Bits: 8

    Parity: None

    Stop Bits: 1

    Flow Control: None

    Any standard DB-9 console cable should work. Failing that, if you just need this for initial configuration have you connected a VGA monitor instead?

    You would need a null-modem female-female, or null-modem male-female plus a gender-changer female-female should work as well if you have a USB-Serial adapter or computer with DB9 male connector.

    Getting serial connections to work, maybe challenging as the standardization seems not always followed. The serial port on the ClearPass server is a 'server port'.

    For the initial setup, a VGA monitor plus USB keyboard should work as well.

    Thank you everyone. The VGA monitor works with the usb keyboard.

    Tip: If you plug in the monitor and do not get console access make sure the hardware appliance is actually turn on. You have to manually push the turn on button in the front after you plug in the power supplies. 

    I will keep trying to find a null cable that works because I would like to plug the ClearPass HW appliance to the console server for remote access.
