System compatibility

Summit X440-48T belongs to X440 gigabit edge switch family, non-PoE variant. Compatible with 1G SFP transceivers. Can stack with other X440 series switches. Supports external redundant power supply. End-of-sale platform, used for enterprise office desktop wired network maintenance replacement.

Function

Summit X440-48T is 1U stackable Gigabit non-PoE access switch for enterprise campus and office. 48 gigabit copper ports connect desktop PCs, printers and non-PoE network terminals. Four combo ports offer flexible uplink selection over copper or fiber. SummitStack merges multiple switches under a single management domain to simplify configuration. Supports 802.1X user authentication, VLAN segmentation and hardware QoS to prioritize voice and video traffic. External redundant power interface improves system uptime. Widely deployed for office, factory and school gigabit wired access layer spare replacement.

InstallationFollow ESD protection procedure. Mount switch to standard 19-inch 1U rack. Connect AC power cord. Install external redundant PSU if required. Insert SFP transceiver for fiber uplink. Deploy SummitStack cable for multi-unit stacking. Access serial console port for initial ExtremeXOS configuration, set VLAN, ACL and QoS policy. Verify stack synchronization and port connectivity after power-up.
