This model offers 48× 10/100/1000 BASE‑T RJ‑45 ports for high‑density user access, including 8 shared PoE ports compliant with 802.3af, providing power for IP phones, wireless access points, and other low‑power devices without external injectors. An expansion module slot accepts optional uplink modules — such as 4× GbE SFP, 2× 10 GbE XFP, or a hybrid 2×10 GbE/4×1 GbE module — enabling flexible connectivity to core or aggregation layers. Redundant internal power supplies and hot‑swappable fans improve availability and uptime in demanding environments. ([turn0search1]
