The CentreCOM 8748SL is a 10BASE-T/100BASE-TX port with 48 ports, a 1U size, and has IP hardware routing, IP filters, multiple hosts, DHCP servers/relays, tagged VLANs, Rapid STP, VRRP, PPPoE clients, and IEEE 802.1X authentication functions.
The CentreCOM 8748SL is a 1U, 48‑port 10/100BASE‑TX Layer 3 Ethernet switch with two GBIC slots for optional 1000BASE‑T, 1000BASE‑SX, 1000BASE‑LX, or 1000M SMF modules. It supports hardware‑based IP routing, including static routes, RIP v1/v2, and OSPF, as well as advanced security features such as hardware and software IP filters and IEEE 802.1X authentication.
The device offers extensive VLAN capabilities (up to 255 VLANs), multi‑domain spanning‑tree protocols, VHRRP for redundancy, and optional feature licenses for firewall, full‑layer‑3, BGP‑4, and IPv6 functions. Technical specifications cover power input (AC 100‑240 V), dimensions (240 mm × 350 mm × 44 mm), and performance metrics such as 13.6 Gbps switching fabric and 1.48 Mpps throughput.
