    I have two 3Com Superstack II Switch 3300's.
    Both have Gigabit ports at the back, can I connect them up using a regular patch cable or do I need to go with a crossover (They break my heart making up!!)

    Thanks in advance! :)

    Gigabit will use straight through OR crossover cables on ANY connection at gigabit speed. Once the ports are running at Gigabit speed it will autodetect and provide the crossover itself, it's part of the standard.

    If you drop the speed to 100Mb then it may not autodetect and reconfigure it's self.

    Thanks for that Capt'n Midnight, however bringing down my network wasn't the aim of the excercise. :mad:

    When I connected up the Gigabit point with straight through cables all my switches started flashing and the network went down. Had to power down all switches, then bring them back up. Caused a lot of bother to say the least. :mad:

    SuperStack 3 Switch 3300 - What version of code should I be running to connect SuperStack switches back to back

    Problem: What version of code should I be running to connect SuperStack switches back to back

    Fact: SuperStack II Switch 3300

    Fact: SuperStack 3 Switch 3300

    Fact: SuperStack 3 Switch 3300 24-Port

    Fact: SuperStack 3 Switch 3300 12-Port

    Fact: SuperStack 3 Switch 3300 SM

    Fact: Gigabit

    Problem: Unable to establish connection between gigabit ports

    Cause: SuperStack 3 Switch is running software version 2.60 or lower and connecting back-to-back.

    Fix: The SuperStack 3 Switch 3300 SM (3C16987A) software agent lower than 2.62 does not operate correctly if the unit is directly linked to another SuperStack 3 Switch 3300 SM using the front panel 1000BASE-SX port.
    You MUST upgrade to the latest version of code.
