2018 júliusa óta a TP-Link az alapértelmezett SFP üzemmódot teljes duplex formában állította be. A TP-Link kapcsolók más készülékekkel, pl. ULTIMODE médiakonverterek, az SFP-portok duplex paraméterének AUTO értékre kell állnia.
The TL-SL2452WEB gigabit-uplink Web Smart Switch fully complies with IEEE 802.3/802.3u/802.3ab/802.3z Ethernet standards. It has forty eight 10/100 Mbps and two 10/100/1000 Mbps UTP/STP RJ45 ports with auto-MDI/MDIX function, and two independent SFP expansion slots supporting MiniGBIC modules. It also provides Web-based management functions including configuration of the network ports, VLANs, trunks, priority and security options etc. The 19-inch rack-mountable steel case and intelligent management solutions make it a perfect device for small, middle and large computer networks.
Distinguishing features:
- Web Smart Switch, 48x Fast Ethernet +2x Gigabit Ethernet (Uplink) ports
- Quick and easy setup via an Internet browser
- Support for Port-Based VLAN and IEEE 802.1Q Tag VLAN
- Support for static MAC address and MAC address filtering
- Port bandwidth control
- Support for Port Trunking
- Support for Port Security, Broadcast Storm Control and Port Mirror
- Virtual Cable Test (VCT)
- Support for Static Port Priority and IEEE 802.1p Class of Service (CoS) with 4-level priority queuing
- Possibility of firmware upgrade, backup and restoring of configuration
- Rack-mountable steel case
- Built-in power supply (AC/DC adapter)
