The HP ProCurve Switch Modules are components that you can add to an HP ProCurve Switch to provide a variety of network connectivity options. The HP ProCurve Switch Module's ports are all configured to be ready for network operation as soon as a viable network cable is connected. Default configuration is applied to the module when the switch is powered on and the module passes self test; this default configuration works well for most network installations. LEDs provide information on the link status, network activity, connection bandwidth, and communication mode (half or full duplex). "Hot swap" operation is supported, so you can add a module or replace a module without having to shut down the switch (changing the module type in a given slot does require a switch reset). Minimize
