Lenovo CE0128TB Gigabit Ethernet Campus Switch

Product Guide

The Lenovo CE0128TB Switch is a 1/10 Gb Ethernet (GbE) switch 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 CE0128TB switch offers 24x 10/100/1000BASE-T (RJ-45) fixed ports and 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 CE0128TB Switch is shown in the following figure.

Key features

The CE0128TB switch is considered particularly suited for the following environments:

Economical network connectivity for 1 GbE access layer deployments in branch and remote offices,
as well as enterprise campus networks.

1 GbE management network connectivity in data center infrastructures.

1 GbE network connectivity with 10 GbE SFP+ ports for additional server, storage, or switch
connections.

Virtualized and cloud environments with multiple 1 GbE ports.

Scalable 1 GbE networking deployments with switch stacking.

Converged infrastructures with 1 GbE NAS or iSCSI.

The CE0128TB switch offers the following features and benefits:

High performance
The 1/10 GbE CE0128TB switch provides a combination of low latency and non-blocking, line-rate
switching.

Availability and redundancy
The CE0128TB switch offers learns alternate routes automatically and performs faster convergence
in case of a link or switch failure.

Layer 3 functionality
In addition to Layer 2 switching, the CE0128TB switch includes Layer 3 functionality, which provides
security and performance benefits of inter-VLAN routing with support for static routes and dynamic
routing protocols, including Routing Information Protocol (RIP) and Open Shortest Path First (OSPF).

Quality of Service
The CE0128TB switch supports traffic classification and processing to provide consistent network
performance and efficient use of network bandwidth by allocating and scheduling resources based
on service levels requirements for different data streams.

Security
Working as an enforcement point, the CE0128TB switch provides standards-based 802.1x port­level access control for multiple devices per port, as well as Layer 2-4 policy enforcement with
Access Control Lists (ACLs).

Stacking
The CE0128TB supports stacking of up to eight campus switches (including intermix of CE0128TB,
CE0128PB, CE0152TB, and CE0152PB switches), enabling simplified, centralized management of a
single logical entity that uses a single switch image, configuration file, management IP address, and
management interface.

Simplified management
To ease deployment, the CE0128TB switch supports the industry-standard Link Layer Discovery
Protocol (LLDP) and GARP VLAN Registration Protocol (GVRP) protocols, enabling the switches
to automatically discover Ethernet-enabled devices and automate VLAN configuration.

AutoInstall
The CE1028TB switch supports the AutoInstall feature, which enables upgrading the switch software
image and installing configuration files via TFTP automatically during the boot process by using the
resources available on the network.

For 1 GbE links, customers can use RJ-45 fixed ports with RJ-45 UTP Category 5 or 5e cables for
distances up to 100 meters.

For longer distances, the 1000BASE-SX transceiver supports distances up to 220 meters with OM1
(62.5 µ) or up to 550 meters with OM2 (50 µ) multimode fiber optic (MMF) cables, or the 1000BASE­LX transceiver supports distances up to 10 kilometers with single-mode fiber optic (SMF) cables.

For 10 GbE links, 10 GbE SFP+ direct-attached copper (DAC) cables can be used for distances up to
7 meters, or 10 GbE SFP+ active optical cables (AOCs) can be used for distances up to 20 meters.
The AOCs and DAC cables have SFP+ connectors on each end, and they do not need separate
transceivers. For distances up to 30 meters, the 10GBASE-T SFP+ transceiver can be used with UTP
Category 6a or 7 cables.

For longer distances, the 10GBASE-SR transceiver supports distances up to 300 meters with OM3 or
up to 400 meters with OM4 MMF cables. The 10GBASE-LR transceivers can support distances up to
10 kilometers with SMF cables. For extended distances, the 10GBASE-ER transceivers can support
distances up to 40 kilometers with SMF cables.
