48-Port Gigabit Managed Switch With 4 Combo SFP Uplinks

Overview

The DGS-3048 is a manageable Layer 2 switch that
provides 48 10/100/1000BASE-T Gigabit Ethernet ports
with 4 Mini-GBIC (SFP) combo ports. Designed for the
‘budget conscious” SMB, it is an all-gigabit-port switch
for gigabit-to-the-desktop connections. Powerful and
versatile, it eliminates network bottlenecks while giving
users the capability to ne-tune performance. 1U height
and standard rack-mount size is especially suitable for
departmental environment, providing users the best
performance/price ratio. Clear, at-a-glance per-device/
per-port LED indicators help users to easily understand
and control network status.

High Performance Wire-Speed Architecture

The DGS-3048 supports full-duplex forwarding, 16k MAC
addresses and the ability to classify and mark trafc
based on 802.1p, MAC, IP, DSCP or TCP/UDP address
into (8) priority queues. The DGS-3048 can be used as
a cost-effective Gigabit to the desktop solution or a high
performance backbone aggregation device.

Network Management

D-Link’s DGS-3048 addresses today’s diverse business
and IT requirements through its robust support of standards
based network management protocols (SNMP/RMON/

BOOTP1/Telnet/Web) and port mirroring. By supporting
standards-based network management protocols, the
DGS-3048 can be easily integrated with most third-party
network management products.

Advanced Enterprise Features

The DGS-3048 brings advanced Enterprise functions
to a new level of affordability without compromising
advanced features including: L2/3/4 QoS, IGMP Snooping,
255 VLANs, Port Trunking, Port Mirroring with support
for many-to-one and one-to-one, 802.1D and 802.1w
Spanning Tree, Port Security, and Network Management.
These features facilitate the deployment of applications
across an Enterprise, including: VOIP, streaming media, and
multicast content delivery (IP video, software deployment
etc). The DGS-3048 provides advanced security features
such as 802.1x port-based access control, and support for
RADIUS server.

Investment Protection

With support for up to (4) SFP modules, the DGS-3048 can
easily adapt to changes in customer media requirements
without the need to perform an expensive “forklift”
upgrade. By supporting SFP/mini-GBIC modules,
customers can migrate to more advanced solutions in
the future, while still protecting a portion of their original
investment.
