Fast Ethernet Layer 3 switch with PoE

The Nortel Networks 4550T-PWR is a stackable Layer 3 switch that provides 48 Fast Ethernet ports with Power over Ethernet support. It targets enterprise networks that need manageable, resilient switching for IP phones, wireless access points and other PoE-powered devices without the cost of Gigabit-to-the-desktop.

Upgrade from unmanaged 10/100 switches

This unit replaces basic unmanaged Fast Ethernet hubs or early Layer 2 switches that lack routing, stacking or PoE. The jump is worth it when you need Layer 3 routing between VLANs, redundant power supply support and the ability to stack multiple 4500 series units into a single logical device.

48 PoE ports with dual SFP uplinks

The switch comfortably handles 48 powered devices at 10/100 speeds while two SFP uplink slots and two Gigabit expansion slots provide aggregation headroom. It runs out when endpoints require sustained Gigabit throughput or when PoE+ power budgets exceed the 10/100 port capability.

Questions about this item

What rack width does the 4550T-PWR fit?

The switch is rack-mountable and desktop sized, fitting a standard rack or a flat surface with its included brackets.

How is the 4550T-PWR initially configured after racking it?

Connect a console cable to the management port, power on the unit, then use the CLI or web interface to assign an IP address and enable stacking if required.

Which field-replaceable part will need attention after several years of PoE use?

The internal power supply is the primary replaceable component; a redundant power supply can be added to the supported slot for failover.
