Switch 4500 - Fast Ethernet. 26- and 50-port models. Two PoE models. Stackable, 24 or 48 10/100 ports plus 4 Dual Personality Ports (2 × Gb or SFPs). Supports Layer 2 switching and Layer 3 static routing, and RIP. Stackable up to 8-units high using Gigabit ports with distributed link aggregation, single IP address management.
All models also have one extension-module slot with either two QSFP 40 Gb ports, 4 SFP+ 10 Gb ports or 4 10GbaseT ports. It is a small (1U) switch with a high port density and can be used as distribution or (collapsed)core switch for campus networks and for use in the data center it offers features such as lossless Ethernet for iSCSI and FCoE ...
Such switches are commonly known as layer-3 switches or multilayer switches. [2] Switches for Ethernet are the most common form of network switch. The first MAC Bridge [3] [4] [5] was invented [6] in 1983 by Mark Kempf, an engineer in the Networking Advanced Development group of Digital Equipment Corporation. The first 2 port Bridge product ...

The original PoE standard, IEEE 802.3af-2003, [1] now known as Type 1, provides up to 15.4 W of DC power (minimum 44 V DC and 350 mA) [2] [3] on each port. [4] Only 12.95 W is guaranteed to be available at the powered device as some power dissipates in the cable.

Stackable switches are customarily Ethernet, rack-mounted, managed switches of 1–2 rack unit (RU) in size, with a fixed set of data ports on the front. Some models have slots for optional slide-in modules to add ports or features to the base stackable unit. The most common configurations are 24-port and 48-port models.
