D-Link DES-3200-52P 48-port 10/100 PoE Layer 2

Flexible Ports Types
24 or 48 10/100 Ports + 2 combo 1000BASE-T/SFP Ports + 2 Gigabit SFP Uplinks, with available PoE give you plenty of options to connect to devices or other switches.

Quiet Fanless Design with Surge Protection
Fanless and Smart Fan Models with and 6 KV surge protection on all Ethernet ports keeps switch operation quiet and increases reliability.

Comprehensive L2 Features
Advanced security and management features allow you to secure, control and monitor the traffic on your network.The DES-3200 Series are members of D-Link’s Layer 2 xStack Managed Switch family designed for the Metro ETTX, FTTX, and Enterprise market. The DES-3200 series offers 24 or 48 10/100Mbps Faster Ethernet Ports with available PoE, plus 2 combo Gigabit/
SFP ports and 2 dedicated SFP ports. It also offers the beneficial design of 2 Gigabit/SFP Combo ports and 2 dedicated SFP ports which provide up to 4 Gbps uplink bandwidth or dual Ethernet ring topology support.

Security & Availability
The DES-3200 Series supports 802.1X Port-based/Host-based Access Control, Guest VLAN,
and RADIUS and TACAS+ Authentication for strict access control over the network. The
IP-MAC-Port Binding feature allows administrators to bind a source IP address with an
associated MAC for a defined port number to enhance user access control. Furthermore
with the DHCP Snooping feature, the switch automatically understands the IP/MAC pairs by snooping DHCP packets and saving them to the IMPB white list. These features play a significant role in keeping the network secure and auditable. The built-in D-Link Safeguard Engine identifies and prioritizes “CPU interested” packets to prevent malicious traffic from interrupting normal network flows and protects switch operation. In addition, the Access Control List (ACL) feature enhances the network security and switch performance.

Resilience & Quality of Service
For mission critical environments the DES-3200 Series supports 802.1D-2004 edition, 802.1w
and 802.1s Spanning Tree Protocols (STP). STP allows you to configure the switch with a
redundant backup bridge path, so transmission and reception of packets can be guaranteed
in the event of any failed switch on the network. The switch also supports 802.1AX (formerly
802.3ad) Link Aggregation, enabling you to group multiple ports in parallel to form a single
port, increasing bandwidth and redundancy for higher availability. For Quality of Service (QoS), the switches support 802.1p. This standard is a mechanism that allows real-time traffic classification into 8 priority levels mapped to 4 queues. Packet classification is based
on TOS, DSCP, MAC Addresses, IP Addresses, VLAN ID, TCP/UDP port number, protocol type
and user defined packet content, which enables flexible configuration especially for real-time streaming multimedia applications such as voice over IP.

Traffic & Bandwidth Control
The bandwidth control feature allows network administrators to define the throughput levels for each port in order to manage bandwidth. It also provides fine granularity to define the ingress/egress traffic limits down to 8kbps segments. The switches also support the Broadcast Storm Control feature which minimizes the chance of a virus attack within the network. Port Mirroring helps administrators facilitate traffic diagnostics or track switch performance and make changes if necessary. Q-in-Q, also known as VLAN stacking, is a powerful yet simple and cost-effective solution which can be used to provide multiple virtual connections and access to multiple services available over the Metro Ethernet.

Multicast Applications
The DES-3200 Series provides IGMP Snooping to prune multicast traffic and to optimize
network performance. The MLD snooping feature minimizes multicast IPv6 packets at the port level to conserve network bandwidth.

Management Capabilities
The DES-3200 Series supports standard management protocols such as SNMP, RMON,
Telnet, SSH/SSL security authentication and DHCP Relay Option 82. A web-based GUI is also
supported for user-friendly interface and easy management. DHCP Auto- Configuration is an enhanced management feature that allows administrators to pre-set configuration and save them to a TFTP server. Individual switches can then get IP addresses from the server for booting up and loading the pre-set configuration. The Link Layer Discovery Protocol (LLDP) allows a network device to advertise its identity and capabilities on the local network, which helps businesses better manage their network topology. Each port on the switch supports the Cable Diagnostics feature that helps to detect cable-related information such as cable length status or cable functionality. D-Link Single IP Management (SIM) simplifies and speeds up management tasks, allowing multiple switches to be configured, monitored and maintained from any workstation running a web browser through one uni
