    High Reliability Hardware Stacking Two of the 10G SFP+ ports are used to connect several SGS-5240 series, enabling to build a virtually logical facility. The SGS-5240 series gives the enterprises, service providers and telecoms flexible control over port density, uplinks and switch stack performance.
  • Page 13 Central IP Stacking Management Positioned as the distribution or aggregation layer switch for large networks, the SGS-5240 series supports IP stacking function that helps network managers to easily configure up to 16 switches in the same series via one single IP address instead of connecting and setting each unit one by one.
  • Page 14 Powerful Network Security The SGS-5240 series offers comprehensive Layer 2 to Layer 4 Access Control List (ACL) for enforcing security to the edge. It can be used to restrict network access by denying packets based on source and destination IP address, TCP/UDP ports or defined typical network applications.
  • Page 15 User’s Manual of SGS-5240 Series Managed Switch Moreover, the SGS-5240 series offers secure remote management by supporting SSHv2 and SSLv3 connection which encrypts the packet content at each session. Intelligent SFP Diagnosis Mechanism The SGS-5240 series supports SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to easily monitor real-time parameters of the SFP and SFP+ transceivers, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.

    User’s Manual of SGS-5240 Series Managed Switch 4.2.10 Spanning Tree Protocol 4.3.10.1 Theory The Spanning Tree protocol can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the switch to interact with other bridging devices in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.
