LEDs for fiber ports have the same meaning as forcopper ports. Uses the first RJ-45 port, which has two connectors (only one canbe used at a time). Plug into # 1 for use as a regular user segment port, or into # 1X for use as a crossover (X position) up-link port for connection to another switch or hub.

Ordering Information

Magnum 4K24C Same as Magnum 4K24F, but with all 24 RJ-45 ports “Copper”. Magnum 4K24F Magnum 4K24CR Ethernet Switch with 22 RJ-45 ports, each auto-sensing for 100Mb / 10Mb FDX / HDX operation. Optional fiber ports may be configured, one or two from the family of modules below, to operate at 100Mb in place of two RJ-45 ports. User-selected fiber port connector types. Each port is switched and provides a full-speed traffic domain with non-blocking performance. Includes internal auto-ranging power supply, cooling fan, and metal brackets for 19” rack-mounting. LEDs and user ports are in the front, power input is in the rear. Units with DC power supply options available. “Reverse” model, same as Model 4K24C except user ports and the power input connectors are in the rear, LEDs are in the front.
