D-Link DES-1250G Web Smart 48-Port 10/100 + 2 Gig Switch
|
Introduction
The
Web Smart DES-1250G is equipped with 48
10/100BASE-TX Fast Ethernet ports and 2
combo 10/100/1000BASE-T/SFP (mini-GBIC)
ports for flexible copper/fiber Gigabit
connection. The DES-1250G is an effective
solution for the small and medium size business
connections. This all-in-one solution economically
integrates Gigabit technology to remove
server bottlenecks, and speed up access
to the network backbone. The DES-1250G is
also furnished with Smart features that
are ideal for simple QoS applications, and
basic network monitoring.
Exceptionally
Smart
The DES-1250G provides Class of Service
features that are suitable for todays
multimedia applications. Through the easy-to-use
Web-based interface, an administrator can
configure VLANs to segregate traffic, Priority
Queues, to prioritize mission-critical data
such as voice or video packets, and Link
Aggregation to create fat traffic pipelines.
The DES-1250G also provides network monitoring
tools such as Port Mirroring and port statistics.
Best of all, the password-protected configuration
interface can be accessed remotely, allowing
the DES-1250G to be monitored from anywhere
on the network.
Easy
To Use
Installation of the DES-1250G is hassle-free.
No configuration is required. Auto-MDI/MDI-X
crossover on all ports eliminate the need
for crossover cables. Auto-Negotiation on
each port senses the link speed of a network
device (either 10, 100, 1000Mbps) and intelligently
adjusts for compatibility and optimal performance.
The DES-1250G also features diagnostic LEDs,
which display status and activity, allowing
for quick detection of network problems.
Superior
Performance
The DES-1250G features a non-blocking wire-speed
architecture with a 13.6Gbps switching capacity
for maximum data throughput. With wire-speed
filtering and store-and-forward switching,
the DES-1250G also maximizes network performance
while minimizing the propagation of bad
network packets.
