System compatibilityB5G124-48 belongs to Extreme Networks B5 stackable switch family, formerly Enterasys. It can stack with other B5G124 and B5K125 series switches. Compatible with Extreme validated 1G SFP transceivers and fiber patch cords. Designed for enterprise campus, office building and low-density server access networks. Widely used for enterprise wiring closet spare replacement.
FunctionB5G124-48 is a high-performance non-PoE Layer3 managed gigabit access switch. It supports static routing, VLAN segmentation, STP/RSTP/MSTP, LACP link aggregation, ACL, QoS, IPv4/IPv6 multicast and SNMP monitoring. It monitors port link status, transceiver DDM data, internal temperature and power supply health. Used to build stacked resilient copper access networks for large campus buildings.
InstallationMount the switch on 19-inch 1U rack. Connect AC power cord, external EPS-C2 redundant power supply can be installed optionally. Insert SFP transceivers and fiber cables for uplink. Connect Cat5e/Cat6 cables to RJ45 access ports. Connect serial console port for EOS configuration. Verify boot sequence and port link status before putting into production.
