Selection Notes

MM992-4CU is the RJ45 copper variant without a securing collar: pick it over the collared version when standard RJ45 plugs are acceptable and the collar's extra retention is not needed, or over the SFP variant when the uplink runs on twisted-pair cable. It supplies fixed copper ports at up to 1000 Mbit/s, so no separate transceiver is needed or can be swapped in. It occupies one media module slot on a modular SCALANCE X switch, so available slot count on the target chassis limits how many can be fitted per unit.
