SCALANCE X accessories, media module MM992-4CU, 4x 1000 Mbit/s RJ45 ports, electrical, without retaining collar. SCALANCEMM992-4CUWith the 4-port media modules, fully modular Layer 3 switches can be flexibly equipped. The use of media modules enables: Expansion of networks by later plugging additional media modules into unused media module slots (possible during operation), Expansion of networks by later plugging additional SFP+ or SFP plug-in transceivers into unused SFP+ slots, Change of cabling technology (e.g. switching from copper to fiber optic or from multimode to singlemode fiber optic), Change of transmission rate (e.g. switching from SFP plug-in transceiver (1000 Mbit/s) to SFP+ plug-in transceiver (10 Gbit/s). Unlimited flexibility for network expansions (e.g. more end devices) or conversions (e.g. switching from copper to fiber optic) or performance increase (e.g. from gigabit to 10 gigabit) through modular construction with media modules and SFP+ or SFP plug-in transceivers. Reduction of storage costs and maintenance effort by focusing on a few Basic device variants.
