Function

5420M-24T-4YE is universal non-PoE gigabit edge switch. The 24 RJ45 ports provide wired access for PC, printer, low-power network terminals. 4 SFP28 slots deliver high-speed 25G fiber uplink for high bandwidth aggregation. Built-in MACsec for link-layer encryption. Supports static routing, VLAN, QoS, port security, storm control, ACL and network monitoring. Flexible OS selection adapts to traditional switched network or fabric architecture.

Installation

Mount the switch to standard 19-inch 1RU equipment rack. Connect protective earthing and AC power cord. Connect RJ45 cables to end network devices. Insert SFP28 transceiver into SFP28 slot and connect fiber cable. Boot and select Switch Engine or Fabric Engine OS. Configure via console or ExtremeCloud IQ. Verify port negotiation, MACsec and stacking status after commissioning.
