24-ти портовый Управляемым Layer2 10/100/1000 мб PoE коммутатором с 24-ти гигабитными портами TX и 2-мя портами SFP.

24-Port 10/100/1000Base-T PoE + 2 Gigabit SFP Layer 2+ Management Current Sharing PoE Switch                                         
EW-P70242L2 is 24-port 10/100/1000Base-T + 2 Gigabit SFP L2+ Management Current Sharing PoE Switch that is designed for medium or large network environment to strengthen its network connection. The 24 10/100/1000Base-T ports support IEEE 802.3at PoE technology, up to 30W per port and maximum 100m transmission distance. The switch equipped with Current Sharing technology to support maximum 500W power consumption for PoE power. The added 2 SFP slots support 100M and Gigabit Fiber transceiver for long distance transmission. The switch also supports Layer 2+ full management software features. These features are powerful to provide PoE Control, Network Control, Management, Monitor and Security features’ requests. It is a superb choice to boost your network with better performance, efficiency and high PoE power consumption.
Current Sharing PoE                                               
EW-P70242L2 equipped with Current Sharing technology to support maximum 500W power consumption for PoE power. There are 2 power modules inside, they work together to provide 500W PoE power to the front 24 PSE ports. Once one of the power modules is failure, the other power module can backup and continuously deliver 250W PoE power. Once the PD clients request higher than 250W power, the user can configure the priority value for the PSE ports, the switch delivers power to the higher priority ports first.
2 Gigabit SFP Open Slots                                         
EW-P70242L2 is a 26-port design. It supports 2 additional SFP open slots to uplink to servers, storage, or other switching devices for long loop reach applications. The 2 SFP slots can support different types, speed and distance SFP transceivers. It also supports legacy 100M SFP transceiver. If the 100M fiber infrastructure is constructed and 100M bandwidth is enough, the 100M SFP transceiver can be an optional choice for the legacy 100M network environment.
Full Layer 2+ Management Features                                         
The switch includes full Layer 2+ Management features. The software set includes up to 4K 802.1Q VLAN and advanced Protocol VLAN, Private VLAN, MVR…advanced VLAN features. There are 8 physical queues Quality of Service, IPv4/v6 Multicast filtering, Rapid Spanning Tree protocol to avoid network loop, Multiple Spanning Tree Protocol to integrate VLAN and Spanning Tree, LACP, LLDP; sFlow, port mirroring, cable diagnostic and advanced Network Security features. It also provides Console CLI for out of band management and SNMP, Web GUI for in band Management.
Advanced Security                                               
The switch supports advanced security features. For switch management, there are secured HTTPS and SSH, the login password, configuration packets are secured. The port binding allows to bind specific MAC address to the port, only the MAC has the privilege to access the network. The 802.1X port based Access Control, every user should be authorized first when they want to access the network. AAA is the short of the Authentication, Authorization and Accounting with RADIUS, TACAS+ server. Layer 2+ Access Control List allows user to define the access privilege based on IP, MAC, Port number…etc.
