48-Port Copper Gigabit Smart Switch
With 4 Combo SFP
The DGS-1248T copper Gigabit Smart Switch presents a cost-effective solution for business to implement Gigabit Ethernet
packet switching with easy fine-tuning of network performance and security. This switch comes with a high port density of 48
10/100/1000BASE-T Gigabit ports, plus 4 combo SFP in a low profile rack-mountable housing. Port trunks are provided for
server deployment and network backbone attachment, while functions important for bandwidth-intensive applications such as
Priority Queues and VLANs are supported to enable you to implement Quality of Service (QoS) and security without having to
go through complex network management usually found in other managed switches.
High Density With 48 Copper Gigabit Ports
4 Combo SFP for Flexible Fiber Connection
Port Trunks for Aggregated Bandwidths
VLANs for Enhanced Security & Performance
48 1000BASE-T ports provide an inexpensive alternative
solution to the fiber-optic. Using your existing low-cost Cat.
5 copper twisted-pair wires as the transmission media, these
ports allow you to instantly upgrade your servers to Gigabit
capability without requiring you to install new, expensive
fiber cables. All ports support 10/100/1000Mbps network
speed auto-sensing, full/half duplex auto-negotiation and
auto MDI/MDIX plug-and-play.
4 combo SFP are provided for flexible fiber connection. You
can select to install optional transceiver modules in these
slots for short, medium or long-distance fiber backbone
attachment. Use of the SFP will disable their corresponding
built-in 10/100/1000BASE-T connections.
Ports can be combined together to create multi-link loadsharing
aggregated bandwidths to a server or a network
backbone. To expand the network, you can also make use of
the port trunks to eliminate bottlenecks between the
cascaded switches. The switch allows you to combine
multiple ports into a trunk, and to create multiple trunks per
switch.
The switch support VLANs to let you improve security and
bandwidth utilization by limiting the broadcast domains and
confining intra-group traffic within their segments. To
segment up the network, VLAN-supported workstations and
servers that are connected to the switch can be grouped into
different Virtual LANs (VLANs).
The switch supports Layer 2 802.1p Priority Queue control
to prioritize network packets. Classification of users' data
priorities can be based on a data packet Priority Queue. This
QoS function support allows you to run bandwidth-intensive
and delay-sensitive applications and to attach video servers
to the switch for videoconference.
The switch supports port mirroring to assist network traffic
monitoring. The network administrator can use this function
as a diagnostic tool or debugging feature, especially when
fending off an attack. It enables you to keep close track of
switch performance and alter it if necessary.
The switch provides easy web-based switch configuration
and network management/monitoring from any networked
station that does away with the need for consoles and
console cables. Network devices are auto-discovered and
displayed on a network topology, and you can receive traps
of system events and port errors while monitoring the
network status and statistics from any workstation.
