Frequently Asked Questions (6)

  • How do I update the firmware on the HP J4818A Switch?

    To update the firmware on your HP J4818A Switch (Series 2300 switches), you can download new code through the Download Port on the front of the switch. This process assumes:

    • The Series 2300 switch is connected by a "null modem" serial cable between the Download Port on the front of the switch and the COM1 or COM2 port on a PC or workstation operating as a terminal. You can also use one of the console cables supplied with "managed" HP ProCurve switches and hubs.
    • The new switch code has been copied from the HP ProCurve web site and is stored on the PC's disk drive.
    • The terminal emulator you are using includes the Xmodem binary transfer feature.

    To perform the download:

    1. From the prompt displayed on the terminal, enter the download command.
    2. Execute the terminal emulator command(s) to begin Xmodem binary transfer of the file stored on your PC. The download may take several minutes.
    3. When the download finishes, the switch automatically resets itself and begins running the new switch code.
    4. To confirm that the operating system downloaded correctly, from the terminal prompt, enter the show version command and verify that the new version is present.

  • How do I reset an HP J4818A Switch?

    You can reset the switch by either:

    • Unplugging and plugging in the power cord (power cycling).
    • Pressing the Reset button on the front of the switch.

    Both methods cause the switch to perform its power-on self-test, which can resolve temporary operational problems. These processes also reset network traffic counters and the System Up Time timer to zero.


    For more information, see page 53 of the manual.

  • How do I connect to an HP J4818A Switch?

    To connect your HP J4818A Switch, follow these steps:

    1. Connect the power cord supplied with the switch to the power connector on the back of the switch, and then into a properly grounded electrical outlet. The switch powers on when the power cord is connected.
    2. Connect the network cables from your network devices or patch panels to the fixed RJ-45 ports on the switch or the ports on any installed transceivers. For RJ-45 connections, push the RJ-45 plug into the RJ-45 jack until the tab clicks into place. The Link LED for the port should light up when power is on for both the switch and the connected device, confirming a powered-on device at the other end of the cable.

  • What are the common error indicators on the HP J4818A Switch?

    The common error indicators on the HP J4818A Switch are displayed by the LEDs:

    • Fault LED (orange):
      • Blinking indicates a fault on the switch, a switch port, or the fan. The Status LED for the faulty component will blink simultaneously.
      • On for a prolonged time after power-on or reset indicates a fatal hardware failure or failed self-test.
    • Self Test LED (green):
      • On indicates the switch self-test and initialization are in progress.
      • Blinking indicates a component of the switch has failed its self-test, with the status LED for that component and the Fault LED blinking simultaneously.
    • Fan Status LED (green):
      • Blinking indicates the cooling fan has failed, and the switch Fault LED will blink simultaneously.
    • Port Link LED:
      • Blinking simultaneously with the Fault LED indicates the corresponding port has failed its self-test.
      • Blinking by itself for transceiver ports indicates a transceiver is installed but the switch has not been reset to initialize it.
    • Mode Select LEDs (!):
      • Lit indicates port Mode LEDs are displaying network events that could require operator attention, such as CRC errors or late collisions.

    For more information, see pages 11, 12 and 48 of the manual.

  • What are the power requirements for the HP J4818A Switch?

    The HP J4818A Switch does not have a power switch and is powered on when the power cord is connected to an active AC power source. The switches automatically adjust to any voltage between 100-127 and 200-240 volts and either 50 or 60 Hz. There are no voltage range settings required. The maximum current is 2.4 A for 100-127 volts and 1.2 A for 200-240 volts.
