Dell Networking 5500 Series

Dell Networking 5500 Gigabit Ethernet switches are scalable access switches that give you the power

and flexibility.

The Dell 5500 series switches are designed to offer secure,

fixed-port Gigabit Ethernet switching solutions to deliver

full wire-speed switching performance. With 24 or 48

built-in copper Gigabit Ethernet ports in a 1U form factor,

the 5500 series has a total switching capacity of up to 176

Gbps to support demanding network environments. The

switches also offer simple management and scalability

via a 40Gbps high-availability stacking architecture that

allows you to manage up to eight switches from a single

IP address, and share the dual SFP+ across the stack for

uplinks to the next layer in your network. The switches are

designed for Energy Efficient Ethernet (802.3az), which will

reduce per port power consumption up to 50% if the link

is idle, and further reduction if ports are inactive.

Stacking and 10Gb support

Your next deployment can be greatly simplified by utilizing

the built-in stacking and 10Gb capabilities of the 5500 series

of switches. Up to 400 ports can be managed from a single

IP address using the highly-available stacking architecture,

and the entire stack can be redundantly linked back to the

rest of the network at 10Gb via the dual SFP+ ports.

Robust security

Advanced security features of 5500 series switches

help protect the network from accidental or malicious

interference. Edge authentication using IEEE 802.1x

provides a meaningful security solution which is centralized

and easier to manage than standard ACLs. The 5500 series

provides password management for increased network

security, encrypted management traffic through SSL or

SSH, and secures SNMP access by filtering hosts based on

IP address. MAC-based port security is designed to prevent

unauthorized MAC addresses from accessing the network.

RADIUS and TACACS+ support enables centralized, remote

authentication of administrative access to the switch.

Advanced switching features

The 5500 series switches feature enhanced VLAN support

such as Voice VLANs and Guest VLANs. Other features

include LLDP (Link Layer Discovery Protocol) which allows

for troubleshooting and enhanced network management

over multi-vendor environments, as well as LLDP-MED and

DHCP Snooping to further expand network security. The

switches also support USB auto-configuration so you can

rapidly deploy the switches in minutes without setting up

complex TFTP configurations or sending technical staff to

remote offices.

Easy, powerful enterprise management

The 5500 series switches feature many enterprise

management capabilities to help network administrators

optimize network traffic including QoS to support

VoIP-capable infrastructures, multicast support to help

reduce unnecessary network traffic, link aggregation

for expanded network bandwidth, and dynamic VLAN

configuration. The 5500 series switches can be managed

via a familiar and intuitive command line interface (CLI),

web GUI, third party SNMP-based management console

applications, Telnet, or serial connections.

Power over Ethernet (PoE) support

The 5500 series PoE switches offer PoE-per-port support

for power-dependent network applications including

WLAN Access Points (WAPs), Voice over IP (VoIP) handsets,

video conferencing and badge reading*. The 5524P

and 5548P switches can provide up to 15.4 watts of

power for network-attached devices on up to 24 ports

simultaneously, with the MPS-600 power module enabling

up to 48 ports.
