Dell 3500 Series - User Manual

To Next Page

The PowerConnect 3500 series is a family of 24-and

48-port Fast Ethernet Layer 2 switches. These Layer 2

switches deliver resilient stacking, advanced security,

enterprise-class management features and Power-over-

Ethernet (PoE, 3524P and 3548P only), as well as deliver

impressive switching capacities of up to 12.8 Gbps (3524

and 3524P) and 17.6 Gbps (3548 and 3548P). The 3500

series can be deployed in a wide number of dierent

network deployment scenarios, including Fast Ethernet

edge client connectivity and wiring closet deployments.

Each rack-mountable switch is 1U high and delivers a

high-performance rack-dense switching solution.

Easy, powerful management

PowerConnect 3500 series switches support a number of

industry-standard management interfaces such as web-

based management, Command Line Interface (CLI), LLDP,

LLDP-MED, and Simple Network Management Protocol

(SNMP v1/v2c/v3). For large network environments, Dell’s

OpenManage

™

Network Manager provides management

control to help conﬁgure large numbers of deployed

switches more easily. 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, and many other features to

assist you in managing your network.

Robust security

Advanced security features of PowerConnect 3500

series switches help protect the network from accidental

or malicious interference. The switches’ IP and MAC-

based Access Control Lists (ACLs) are designed to

prevent unauthorized MAC addresses from accessing

the network. SNMPv3, SSL, and SSH encryption oer the

added security of encrypting switch management trac.

RADIUS and TACACS+ support enables centralized,

remote authentication of administrative access to the

switch. Edge authentication using IEEE 802.1x provides

a meaningful security solution which is centralized and

easier to manage than standard ACLs. The 3500 series

also supports DHCP snooping.

Advanced switching features

The PowerConnect 3524 and 3548 switches support a

variety of standards-based advanced switching features,

allowing a network administrator to optimize trac ﬂow in

the network. Up to 256 VLANs are supported, as well

as the IEEE 802.1p protocol to prioritize trac based

upon Layer 2 and Layer 3 information. Other advanced

features include port mirroring, dynamic link aggregation

(LACP), SMTP, and dedicated voice VLAN support for

voice-centric environments.

The PowerConnect 3524P and 3548P oer Power-over-

Ethernet capabilities to power IEEE 802.3af compliant

network-attached devices, such as wireless LAN access

points, VoIP handsets, and video cameras. Both switches

can provide up to 15.4W of power per port simultaneously

for PoE operation (the EPS-470 extended power supply is

required for the PowerConnect 3548P).

High availability

The PowerConnect 3500 series oers high availability

features to meet enterprise networking needs such as

resilient stacking that can help the network survive a switch

failure within the stack. Multiple Spanning Tree Protocol

and Rapid Spanning Tree Protocol support help reduce

network setup time and improve network availability.

Lifetime Warranty*

Select PowerConnect switches are backed

by an industry-leading, lifetime warranty

which guarantees Basic Hardware

Service (repair or replacement) for life.

PowerConnect switches not only provide the quality,

reliability and capability you expect from Dell, but also the

peace of mind that comes with a true lifetime warranty.

The Dell PowerConnect 3500 Series comprises stackable Fast Ethernet switches designed for high-performance workgroup connectivity, offering advanced management and security features. This series includes 24- and 48-port Fast Ethernet Layer 2 switches, available in both standard and Power-over-Ethernet (PoE) enabled models (3524P and 3548P). These switches are rack-mountable (1U high) and provide a high-performance, rack-dense switching solution suitable for various network deployment scenarios, including Fast Ethernet edge client connectivity and wiring closet deployments.

Function Description:

The PowerConnect 3500 series switches primarily function as Layer 2 network switches, facilitating data transfer within a local area network. They support resilient stacking, allowing multiple switches to operate as a single logical unit, which enhances network availability and simplifies management. The PoE-enabled models (3524P and 3548P) extend their functionality by providing power to IEEE 802.3af compliant network-attached devices such as wireless LAN access points, VoIP handsets, and video cameras directly over the Ethernet cable, eliminating the need for separate power sources for these devices.
