privacy. Furthermore, the XGSW-28040HP provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection
functions to prevent IP snooping from attack and discard ARP packets with invalid MAC address. The network administrators
can now construct highly secured corporate networks with considerably less time and effort than before.
Robust Layer 2 Features
The XGSW-28040HP can be programmed for advanced switch management functions such as dynamic port link aggregation,
Q-in-Q VLAN, private VLAN, Multiple Spanning Tree Protocol (MSTP), Layer 2/4 QoS, bandwidth control and IGMP/MLD
Snooping. The XGSW-28040HP also provides 802.1Q Tagged VLAN, and the VLAN groups allowed will be maximally up to
256. Via aggregation of supporting ports, the XGSW-28040HP allows the operation of a high-speed trunk combining multiple
ports. It enables up to 14 groups of 8 ports for trunk maximum and supports connection fail-over as well.
Excellent Traffic Control
The XGSW-28040HP is loaded with powerful traffic management and QoS features to enhance connection services by SMBs.
The QoS features include wire-speed Layer 4 traffic classifiers and bandwidth limitation that are particular useful for multi-tenant
unit, multi business unit, Telco, or Network Service Provider applications. It also empowers the enterprises to take full
advantages of the limited network resources and guarantees the best performance in VoIP and video conferencing
transmission.
Efficient and Secure Management
The XGSW-28040HP Managed Switch is equipped with console, WEB and SNMP management interfaces. With the built-in
Web-based management interface, the XGSW-28040HP offers an easy-to-use, platform-independent management and
configuration facility. The XGSW-28040HP supports standard Simple Network Management Protocol (SNMP) and can be
managed via any management software that supports SNMP protocol. For text-based management, the XGSW-28040HP can
be accessed via Telnet and the console port. Moreover, the XGSW-28040HP offers secure remote management by supporting
SSH, SSL and SNMPv3 connection which encrypt the packet content at each session.
Flexibility and Extension Solution
The XGSW-28040HP provides 4 extra Gigabit TP/SFP combo interfaces supporting 10/100/1000Base-T RJ-45 copper to
connect with surveillance network devices such as NVR, Video Streaming Server or NAS to facilitate surveillance management.
Or through these dual-speed fiber SFP slots, it can also connect with the 100Base-FX / 1000Base-SX/LX SFP (Small
Form-factor Pluggable) fiber transceiver to backbone switch and monitoring center in long distance. The distance can be
extended from 550 meters to 2 kilometers (multi-mode fiber) and up to above 10/20/30/40/50/70/120 kilometers (single-mode
fiber or WDM fiber). They are well suited for applications within the enterprise data centers and distributions.
Intelligent SFP Diagnosis Mechanism
The XGSW-28040HP supports SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to
easily monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias
current, and transceiver supply voltage.
