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 26

    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.

  • Page 27: Verify The Switch Passes Self Test

    The Switch 2800 Series devices do not have a power switch. They are 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 43: As A Segment Switch

    LEGEND: Fast Ethernet cable The Switch also works well as a segment switch. That is, with its high performance, it can be used for interconnecting network segments—simply connect the network hubs that form those segments to the switch, or you can also connect other switches.

  • Page 44

    Sample Network Topologies Because the Switch has the “IEEE Auto MDI/MDI-X” features, the connections between the switch and the hubs, and between the switch and end nodes or servers can be through category 5 “straight-through” or “crossover” twisted- pair cable. Category 3 or 4 cable can also be used if the connection is 10 Mbps only.

  • Page 45: 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 5304xl 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.

  • Page 50: Using The Console Setup Screen

    The quickest and easiest way to minimally configure the switch for manage- ment and password protection in your network is to use a direct console connection to the switch, start a console session, and access the Switch Setup screen. Using the method described in the preceding section, connect a terminal device to the switch and display the switch console command (CLI) prompt (the default display).

    Recommended; If you set IP Config to Manual, then enter an IP address Note: The IP address and subnet mask assigned for the switch must be compatible with the IP addressing used in your network. For more information on IP addressing, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch.

  • Page 52: Where To Go From Here

    The above procedure configures your switch with a Manager password, IP address, and subnet mask. As a result, with the proper network connections, you can now manage the switch from a PC equipped with Telnet or a web browser interface.

  • Page 53: Using The Ip Address For Remote Switch Management, Starting A Telnet Session

    With the Switch 2800 Series devices, you can use the switch’s IP address to manage the switch from any PC that is on the same subnet as the switch. You can use either a Telnet session or a standard web browser to manage the switch.
