HP J4118A 10 BASE-FL FIBER EXPANSION MODULE

The HP ProCurve Switch Modules are components that you can add to an HP ProCurve switch to provide a variety of network connectivity options. This is a HP ProCurve Switch 10Base-FL Module with 4 fiber-optic ports with ST connectors for 10 Mbps operation over multimode fiber-optic cable. The HP ProCurve Switch Modules have the following features: auto-enabled ports-the ports are all configured to be ready for network operation as soon as a viable network cable is connected; auto-configuration-a 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 that provide information on the link status, network activity, connection bandwidth, and communication mode (half or full duplex); "hot swap" operation-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). This 10Base-FL Module complies with the IEEE 802.3j 10Base-FL standard.
