Rack-Dense Wire-Speed Performance
The PowerConnect 3400 series is a family of four 24 and 48-port Fast Ethernet layer 2 switches. These Layer 2 switches deliver
stackable Fast Ethernet switches offer
resilient stacking, advanced security, enterprise-class management features and Power-over-Ethernet (PoE, 3424P & 3448P only).
These Dell designed switches deliver impressive switching capacities of up to 12.8 Gbps (3424 & 3424P) and 17.6 Gbps (3448
advanced management and security
& 3448P). The 3400 series can be deployed in a wide number of different network deployment scenarios, including Fast Ethernet
features for high-performance
edge client connectivity and wiring closet deployments. Because these switches adhere stringently to industry standards, they
can be deployed with other industry-standard compliant networking devices, from security appliances to routers and even
workgroup connectivity.
to other switches. Each rack-mountable switch is 1U high and delivers a high-performance rack-dense switching solution.
Easy, Powerful Management
PowerConnect 3400 series switches support a number of industry-standard management interfaces such as web-based
management, Command Line Interface (CLI), and Simple Network Management Protocol (SNMP v1/v2c/v3). For large network
environments, Dell's OpenManage
™
Network Manager provides management control to more easily configure large numbers
of deployed switches. This powerful application is included, at no additional charge, with our managed switches and provides
one-to-many configuration changes, trap/event monitoring, network discovery, topological mapping and many other features to
assist you in managing your network.
Robust Security
Advanced security features of the PowerConnect 3400 series switches help protect the network from accidental or malicious
interference. MAC-based port security and MAC-based Access Control Lists (ACLs) are designed to prevent unauthorized MAC
addresses from accessing the network SNMPv3, SSL and SSH encryption offer the added security of encrypting switch
management traffic. RADIUS and TACACS+ support enables centralized, remote authentication of administrative access to the
switch. Management access filtering provides a mechanism to limit network hosts that have access to the switches using
a wide array of options, such as MAC address, IP address, and VLAN. Edge authentication using IEEE 802.1x provides
a meaningful security solution which is centralized and easier to manage than standard ACLs. Now, users can be added to a RADIUS
database and allowed access to the network. Others, who do not have proper credentials, will not have access to the network.
Advanced Switching Features
The PowerConnect 3424 and 3448 switches support a variety of standards–based advanced switching features, allowing
a network administrator to optimize traffic flow in the network. Up to 256 VLANs are supported, enabling limitation of broadcast
domains as well as improved network security. Network traffic prioritization is a key requirement for deploying emerging
applications like videoconferencing and voice-over-IP. These switches support the industry-standard IEEE 802.1p protocol and
prioritize traffic based upon Layer 2 and Layer 3 information. Other advanced features include port mirroring, dynamic link
aggregation (LACP), SNTP and IP multicast support. These capabilities help increase deployment flexibility, better enable VoIP
deployments and help protect networking infrastructure investments.
Power-Over-Ethernet
The PowerConnect 3424P and 3448P offer Power-Over Ethernet capabilities to power network-attached devices, such as wireless
LAN access points, VoIP handsets, video cameras and badge readers that are compliant with the IEEE 802.3af standard. With
a tremendous 470W of power available to the switch for switching and PoE operations, both switches can provide up to 15.4W
of power per port simultaneously (3448P requires EPS-470 for full 15.4W per port for all ports). An extended power supply, the
EPS-470, can be connected to the switch to provide two basic but important functions. Whenever the switch power system is
functioning properly, the EPS-470 will load share the power so that the full 15.4W of power per port can be provided to all ports.
It also serves as a redundant power supply in the unlikely event the main power supply should fail. With this new industry-standard
PoE capability, Dell's PowerConnect switches can connect you to the power.
High Availability
Dell PowerConnect 3424, 3424P
The PowerConnect 3400 series offers several high availability features to meet enterprise networking needs. The switches can
be resiliently stacked together to provide a highly available solution that can help the network survive a switch failure within
the stack. The stack of switches consists of a master and backup switch that are continuously synched together so that a failure
of the master unit or any other switch will not adversely affect the performance or connectivity of the other stacked switches.
Multiple Spanning Tree Protocol and Rapid Spanning Tree Protocol support help reduce network setup time and improve network
availability. These industry standard protocols provide rapid reconvergence in the event of network outages even across large
networks with many VLANs.
