    ■ HP Procurve Gigabit-LH-LC mini-GBIC (J4860A) C a u t i o n The HP Procurve mini-GBICs are Class 1 laser devices. Avoid direct eye exposure to the beam coming from the transmit port. Installing the mini-GBICs: Hold the mini-GBIC by its sides and gently insert it into either of the slots on the switch until the mini-GBIC clicks into place.
  • Page 23 You should disconnect the network cable from the mini-GBIC before removing it from the switch. Depending on when you purchased your HP Procurve mini-GBIC, it may have either of three different release mechanisms: a plastic tab on the bottom of the mini-GBIC, a plastic collar around the mini-GBIC, or a wire bail.

    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.
