Cable for AOS-CX switch console and serial console server

  • 1.  Cable for AOS-CX switch console and serial console server

    Posted Feb 18, 2022 08:15 AM

    Hi,

    I'm having a hard time when trying to identify which type of a cable is required to connect AOS-CX switch (6000-6300) and serial console server / RJ45 (Raritan Dominion SX II / DSX2-32). Tested some USB-C to RJ45 and USB-A to RJ-45 but with no success.

    If I have understood right, the console server should be connected to the switch USB-A / AUX and not the USB-C / console port?

    Maybe someone knows and could share information of exact cable type that is required and verified to work (type/model, manufacturer, part number etc.)?

    Now I could be very wrong but USB-A port is for external storage and usb-c is for console...

    I have used only usb-c cable and for my Serial-program Needs 115200bps 8/n/1 console speed to have successful connection.

    Edit: and cable I'm using is "normal" 1.5m Otterbox  usb-c -> usb-c cable.

    Use the USB A port and a rollover cable/adapter.

    Depend of which ports your Console server have :

    Console Server=>Switch:
    RJ45/rs232 serial adapter => rs232/usb-A (like a cisco switch on your computer but inverted) 
    or
    usb-C => usb-C 
    or
    usb-A => usb-C

    But it sucks the 6000CX's does not have RJ45 serial ports likes the 8000CX.. usb is not a reliable connexion for datacenter.

    Thanks to everyone.

    (@JorchRock67: I am seeking a USB - RJ45 serial cable.)

    According to the link Evan provided a cable with chipsets FT231X / PL3202 should work.
    There is also mention that USB-A should be used.


    My observations:

    Raritan has autodetection.
    When connecting example 2530 console to Raritan using RJ45 - RJ45, Raritan autodetects its role as DCE.

    I have now successfully connected 6100 USB-A / AUX to Raritan / RJ45 using combination:

    "Cisco Serial Cable RJ45-DB9" + "DB-9 USB 2.0 to Serial 9-Pin RS-232 Converter Cable"
    Converter cable has FTDI chipset (not sure of exact chip version).
    https://ftdichip.com/products/us232r-10-bulk/

    Raritan autodetects the port role as DTE and console access works just fine.

    Example this did not work of the converters I tested: 
    https://www.aten.com/eu/en/products/usb-&-thunderbolt/usb-converters/uc232a/

    I am primary looking for part/order number for "one-cable" solution that can be applied between Console server (Raritan) and AOS-CX (models 6000 - 6300). 


    Example this should have the suggested FT231X-chip: https://www.amazon.com/Tekit-Cisco-Router-Console-Cable/dp/B07CV9GJM8
    Has someone maybe verified if this cable works on this use-case?
    (I assume that there are 6000-6300 series used in such a critical environments where an emergency console access is required... and hoping that someone has already figured out a 100% working cable :-) )

    Meanwhile there is a cable available from Aruba:

    (R8Z87A)  Aruba USB-A to RJ45 PIN3TX-6RX Cable

    R8Z87A is wired so that the RJ45 plug presents Pin3 as a TX  (connects to the TermServer wired with Pin3=RX) and Pin6=RX to connect to a Pin6=TX

    The USB-A to RJ45 cable is 2.5m/8.2ft long

    I can also recommend the following combination:

    - https://www.aten.com/global/en/products/usb-&-thunderbolt/usb-converters/uc232b/
    - https://www.startech.com/en-us/cables/rollover

    Thanks Holger!

    I had totally overlooked the switch datasheet as a source of this kind of accessories.
    Great to know that an "original" Aruba cable is available, I will try to get my hands on to one and test it.

    Just to give a status update:

    • "(R8Z87A) Aruba USB-A to RJ45 PIN3TX-6RX Cable" - Local distributor has ordered these cables (but so far has not been able to provide availability information).

    • Following is verified to work: "DriverGenius USB RJ45 Cisco Console Cable FTDI Chip - USB RS232/DB9 to RJ45 Console"

    Hello rlillqvist,

    can you give us a feedback to this topic?
    Works the "(R8Z87A) Aruba USB-A to RJ45 PIN3TX-6RX Cable" from Aruba too?

    Thank you!

    Hi DPongratz3,

    Unfortunately I have not been able to test R8Z87A. Local availability of R8Z87A has not changed (distributor has not yet received these cables). But I assume it works, since it is Aruba product.
