The NGSM24G4S 24-port 10/100/1000Base-T and 2 10G SFP+ for Stacking and 2 10G SFP+ Open Slot Rack-mount L2+ Full Management Network Switch is designed for medium or large network environments to strengthen the network connectivity. The switch supports 136G non-blocking switch fabric, the 24 gigabit ports and 2 10G ports can transmit and receive data traffic without any lost. The EEE feature reduces the power consumption automatically when there is no traffic forwarding, even when the port is still connected.
The 10G uplink port design is available and important for high bandwidth uplink request when cascaded with other switches. The switch also supports Layer 2+ full management software features to provide network control, management, monitor and security feature requests.  Including rack-mount brackets, the 19″ size fits into your rack environment. It is a superb choice to boost your network with better performance and efficiency

Description

The NGSM24G4S 24-port 10/100/1000Base-T and 2 10G SFP+ for Stacking and 2 10G SFP+ Open Slot Rack-mount L2+ Full Management Network Switch is designed for medium or large network environments to strengthen the network connectivity. The switch supports 136G non-blocking switch fabric, the 24 gigabit ports and 2 10G ports can transmit and receive data traffic without
any lost. The EEE feature reduces the power consumption automatically when there is no traffic forwarding, even when the port is still connected. The 10G uplink port design is available and important for high bandwidth uplink request when
cascaded with other switches. The switch also supports Layer 2+ full management software features to provide network control, management, monitor and security feature requests. Including rack-mount brackets, the 19″ size fits into your rack environment. It is a superb choice to boost your network with better performance and efficiency.

2 10 Gigabit SFP+ Open Slots
The NGSM24G4S has 2 10G SFP+ open slots as uplink ports. The 10G uplink design provides an excellent solution for expanding your network from 1G to 10G. At 10G speed, this switch provides high flexibility and high bandwidth connectivity to another 10G switch or tServers, Workstations and other attached devices supporting 10G interface. The user can also aggregate the 10G ports as Trunk group to enlarge the bandwidth.

Stacking Features
The switches include a stacking feature by using 2 SFP+ ports that allows multiple switches to operate as a single unit. A single switch in the stack can manages all the units in the stack and
uses a single IP address which allows the user to manage every port in the stack from this one address. These stacks can include up to 16 switches, or a total 384 gigabit ports plus 32 10G ports
in a switch.

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…features. There are 8 physical
queues Quality of Service, IPv4/v6 Multicast filtering, Rapid Spanning Tree protocol to avoid network loops, 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.

802.3az Energy Efficient Ethernet
The EEE feature reduces the power consumption automatically when there is no traffic forwarding, even when the port is still connected.

Optional PoE Features (NGSME24G4S)
The PoE switch is 802.3af/at Compliant, with a maximum power Outper Per port of 30W, Total Power Consumption is 500W Current Sharing.

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.
