This guide is intended for technical specialists, sales specialists, sales engineers, IT architects, and other IT professionals who want to learn more about the CE0128PB switch and consider its use in IT solutions.

Introduction
The Lenovo CE0128PB Switch is a 1/10 Gb Ethernet (GbE) switch with Power over Ethernet (PoE) that delivers a compact, high-density, cost-effective GbE solution for network environments where space and power are at a premium. Featuring a small, 1U footprint, this switch is designed for access-layer deployments in branches, retail and workgroup environments, and campus networks. It can also be used as a management network switch in the data center infrastructures.

The CE0128PB switch offers 24x 10/100/1000BASE-T (RJ-45) fixed ports with Power over Ethernet (PoE) for powering attached network devices, such as such as telephones, video cameras, IEEE 802.11ac WLAN access points, and videophones. The switch also offers 4x SFP+ ports that support 1 GbE and 10 GbE optical transceivers, 10 GbE active optical cables (AOCs), and 10 GbE direct attach copper (DAC) cables. The switch supports a wide range of L2 and L3 features that provide performance, availability, security, and manageability for campus networks.

The Lenovo CE0128PB Switch is shown in the following figure.

Did you know?
The CE0128PB switch can simultaneously deliver up to 15.4 watts of standards-based 802.3af Class 3 PoE to a maximum of 12 ports or 30 watts of standards-based 802.3at PoE+ to a maximum of 6 ports.

The CE0128PB switch supports the LLDP-Media Endpoint Discovery (LLDP-MED) protocol, enabling the switches to automatically discover Ethernet-enabled devices, determine their power requirements, and assign virtual LAN (VLAN) membership.

The CE0128PB switch supports stacking, enabling up to eight interconnected switch devices to be managed as a single logical device.

The CE0128PB switch supports AutoInstall, which enables a switch to automatically configure itself using the resources available on the network, without manual intervention.
