    On briefly after the switch is powered on or reset, at the beginning of switch self test. If on for a prolonged time, the switch has a hardware failure, or has failed its self test. See chapter 3, “Troubleshooting” for more information.
  • Page 10: Led Mode Select Button And Indicator Leds

    To optimize the amount of information that can be displayed for each of the switch ports without overwhelming you with LEDs, the Switch 2124 uses a Mode LED for each port. The operation of this LED is controlled by the LED Mode Select button, and the current setting is indicated by the Mode indicator LEDs near the button.

  • Page 13 Switch 2124 cannot know whether to forward or filter out the packet. In this case, it sends the packet to all the other switch ports. This is referred to as “flooding”. When the destination device receives the packet, it replies, and the switch learns the new address from the reply packet.
  • Page 15: Installing The Switch 2124

    Installing the Switch 2124 The HP Switch 2124 is easy to install. It comes with an accessory kit that includes the brackets for mounting the switch in a standard 19-inch telco rack or an equipment cabinet, or on a wall, and with rubber feet that can be attached so the switch can be securely located on a horizontal surface.
  • Page 16: Installation Procedures

    Please see page 2-3 for some installation precautions. (Optional) Install the transceiver. The Switch 2124 has a slot for installing an HP 100-FX SC Transceiver (HP J4853A). Depending on where you will locate the Switch 2124, it may be easier to install the transceiver first.
  • Page 17: Installation Precautions

    Installation Precautions: Follow these precautions when installing your HP Switch 2124. W a r n i n g The rack or cabinet should be adequately secured to prevent it from becoming unstable and/or falling over. Devices installed in a rack or cabinet should be mounted as low as possible, with the heaviest device at the bottom and progressively lighter devices installed above.
  • Page 18: Prepare The Installation Site

    Installation Location - Before installing the switch, plan its location and orientation relative to other devices and equipment: • At the front of the switch, leave at least 7.6 cm (3 inches) of space for the twisted-pair and fiber-optic cabling. •...

    2. Install An Optional Transceiver Install an optional HP 100-FX SC Transceiver into the transceiver slot as shown in the illustration below, or by following the instructions in the manual that comes with the transceiver. The slot cover can be removed with either a flat-bladed or Torx T-10 screw- driver.
  • Page 20: Verify The Switch Operates Correctly

    N o t e The Switch 2124 does not have a power switch. It is powered on when the power cord is connected to the switch and to a power source. For safety, the power outlet should be located near the switch installation.
  • Page 21 Power and Fault LEDs When the switch is powered on, it performs its diagnostic self test. The self test takes approximately 3 seconds to complete. LED Behavior: During the self test: • All the switch and port LEDs are on.
  • Page 22: Mount The Switch

    4. Mount the Switch After a transceiver has been installed and you have verified that the switch passes its self test, you are ready to mount the switch in a stable location. The Switch 2124 can be mounted in these ways:...

    Place the switch on a table or other horizontal surface. The switch comes with rubber feet in the accessory kit that can be used to help keep the switch from sliding on the surface. Attach the rubber feet to the four corners on the bottom of the switch within the embossed angled lines.
  • Page 27: Connect The Network Cables

    Connect the network cables, described under “Cabling Infrastructure” (page 2-4), from the network devices or your patch panels to the fixed RJ-45 ports on the switch, or to an HP 100-FX SC Transceiver, if one is installed in the switch.
  • Page 28: Example Network Topologies

    Notice that the end node devices are connected to the switch by “straight-through” or “crossover” twisted-pair cables. Either cable type can be used because of the “HP Auto-MDIX” feature on the Switch 2124. N o t e The HP 100-FX SC Transceiver, when installed in a Switch 2124, operates only at 100 Mbps and full duplex.
  • Page 29: As A Segment Switch

    The switch, in turn, is connected to a network backbone through fiber-optic cabling connected to an HP 100-FX SC Transceiver installed in the switch. Now, all the devices on these network segments can access other network resources that are connected elsewhere on the network backbone.
  • Page 30: Connecting To A Backbone Switch

    The simpler desktop and segment networks shown in the previous two examples can easily be combined and expanded. For example, you could use an HP Procurve Switch 8000M to interconnect each of your smaller switched workgroups to form a larger switched network. All the devices in this network can communicate with each other.
