    8000 address table and high performance as the Switch 208T, it also can be used as a segment switch. Or, you could, of course, connect a combination of end nodes and hubs to the Switch 224T ports.

  • Page 25: Connecting To A Backbone Switch

    The simpler segment and desktop networks shown in the previous two examples can easily be combined and expanded. For example, you could use an HP Switch 2000 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.

    AC power connector Redundant Power Supply (RPS) Connector The RPS connector allows you to connect this switch to the HP J2962A Redundant Power Supply. A single RPS shares the load with up to 4 switches. The RPS has redundant power supplies to keep the switch up and running; it is used in place of the switch’s standard power cable (NOT in addition to it).

    Address Table Operation Address Learning. As devices are connected to the switch ports, either directly or through hubs or other switches that are connect to the switch, the MAC addresses of those devices are learned automatically and stored in the Switch 208/224’s 8000-entry address table.

  • Page 33: Simultaneous Network Communications

    In the case of the Switch 224T, with its 26 ports, it can have up to 13 separate network connec- tions going simultaneously. Instead of sharing the network bandwidth, as in connections to a hub, each connection has its own 10 Mbit/s or 100 Mbit/s bandwidth to use.

  • Page 35: Troubleshooting

    This chapter describes how to troubleshoot your Switch 208/224. Note that if you have a Switch 208/224 Management Module, you can troubleshoot your switch using software. See the HP AdvanceStack Switch 208/224 Manage- ment Module Installation and Reference Guide for more information.
