WHY CHOOSE THIS PRODUCT?

• Organizations choose the ST2GPEX when a compatible desktop, workstation or server needs a practical upgrade to 2.5GbE without moving immediately to a higher-speed network architecture. Its four supported Ethernet speeds, 2.5GBASE-T and NBASE-T compatibility, CAT5e support, standard and low-profile installation options, PXE, VLAN tagging and Wake-on-LAN make it suitable for varied enterprise connectivity requirements. Compared with a conventional Gigabit-only adapter, it provides a higher-speed migration path while retaining compatibility with slower Ethernet networks. For procurement teams, the single-port design, included low-profile bracket and backward speed compatibility support targeted upgrades, replacement deployments and phased infrastructure modernization.
