DES-3252P
Web Smart 48-Port 10/100 PoE Switch, 4 Gigabit Copper Ports
The D-Link Web Smart 48-Port 10/100 PoE Switch with 4
®
Gigabit Copper Ports and 2 Combo SFP Uplinks (DES-3252P)
provides advanced enterprise network management
features at a cost-effective level. With 48 PoE ports,
each port is capable of providing up to 16.8 Watts to
the attached PoE device. Designed for VoIP deployment
with rich QoS options, the DES-3252P also emphasizes
security with enhanced Access Control Lists (ACLs). The
DES-3252P offers 4 gigabit copper ports and 2 SFP combo
ports for backbone connections. The 2 SFP combo ports
support optional gigabit or 100BASE-FX transceivers
for backbone connections up to 10km away. As with all
D-Link Web Smart switches, the DES-3252P utilizes a
user-friendly Web-based user interface in addition to a
standard configuration CLI to facilitate fast configuration,
even with universal ACL rules. The DES-3252P is also ideal
for connecting edge access equipment such as wireless
cameras, wireless access points, or VoIP phones.
IEEE 802.3af Power over Ethernet
Wherever the location—factory, warehouse, campus,
small office, or enterprise facility—the challenge and
cost of running power to difficult-to-reach locations in
order to meet network design can become a disruption to
business and a drain on resources. To solve this problem,
the DES-3252P is equipped with 48 10/100BASE-T ports
that support the 802.3af PoE protocol. The DES-3252P is
designed to inject up to 16.8 Watts of power per port on
all 48 RJ-45 ports to support IP phones, access points,
Cameras, and more. D-Link can even supply power
and add PoE operability to non-PoE products with the
DWL-P50 adapter.
Comprehensive Security
The DES-3252P protects against many of today's
emerging security vulnerabilities previously delegated
to standalone firewalls. It supports ACLs for controlling
traffic based on Layer 2/3/4 criteria. Port and MAC
based 802.1x authentication prevents unauthorized
network logins. On top of that, port-based security
protects the integrity of the entire network.
Advanced QoS
The DES-3252P provides a robust and consistent set of
QoS/CoS, supporting 4 priority queues for 802.1p/ToS/
DiffServ, with classification and marking based on MAC
SA/DA, IP SA/DA, and/or TCP/UDP. It also provides
multicast support with IGMP Snooping. IGMP Snooping
analyzes data packets and forwards them through only
where appropriate so multicast packets, such as streaming
audio and video or other bandwidth hogs, can get through
without creating extra network congestion. This smart
packet management also reduces the workload of other
devices further down the line, making your entire network
function more efficiently. Further traffic management
can be done through IEEE 802.1Q VLANs and port-based
VLANs for up to 255 groups per device. Comprehensive
QoS features facilitate VoIP and video deployments to
prevent voice packet drops or video jitters. The DES-3252P
also offers bandwidth management and egress/ingress
options for administrators to set limitations per port.
High Availability
The DES-3252P supports an optional Redundant Power
Supply, ensuring the availability of the network to the end
nodes attached to the switch. The DES-3252P also features
IEEE 802.3d Spanning Tree, 802.1s Multiple Spanning Tree,
and 802.1w Rapid Spanning Tree for increased network
reliability and availability.
Network Management
The DES-3252P features a variety of network
management options, a Graphic User Interface (GUI)
for easy configuration and an industry-standard CLI
for advanced users. SNMPv1/v2c/v3, RMON, SYSLOG
are available for monitoring network status, while port
mirroring can be used to observe traffic for a designated
port. Management traffic can be encrypted through SSH
and SSL options.
