Introduction

This guide describes the latest hardware changes and improvements for the Cisco CBS110 Series Unmanaged Switches. It is intended to help users and installers understand what's new in the refreshed models and how these changes may affect installation or usage.

CBS110 Hardware Refresh Overview

The CBS110 series unmanaged switches have undergone a hardware refresh, impacting 7 models. These refreshed models maintain the same Hardware Product ID (HW PID) but feature updated Version IDs (VID).

  • 7 Refreshed Models: The CBS110 refresh includes 7 unmanaged switch models.

  • CBS110-24PP and CBS110-24T: front ports update from 22*GE+2*Combo to 24*GE+2*Combo.The max ports supported will change from 22*GE+2*Combo (port 23 & port 24) to 24*GE+2*Combo (port 25 & port 26).

  • Product ID (PID): All models keep the same hardware PID, with only the hardware version (VID) updated.

  • Operating Temperature: extended to 0-50 C for improved environmental tolerance.

  • ASIC Solution: All models use updated SoC and PoE solutions for better performance and reliability.

  • CBS110-5T-Dimensions change from 110 x 75 x 30 mm to 110 x 100 x 30 mm (width x depth x height).

  • CBS110-16T: front ports arrangement change from 1*8*2 to 2*4*2.

Effect of Change - No change to function. Refer to the CBS110 Data Sheet for detailed specifications.

Model Specific Updates

Specific hardware changes have been implemented for certain models:

  • CBS110-24T and CBS110-24PP

    • Due to the ASIC update, these models will feature 2 extra GE copper ports.

    • The front port configuration changes from the previous 22*1G + 2 Combo (SFP+1G Cu) layout to a new configuration of 24*1G + 2 Combo.

  • CBS110-16T

    • The front port layout changes from 1*8*2 to 2*4*2. This change is made to share the PCB design with the CBS110-16PP model.

  • CBS110-5T-D:

    • The overall physical dimensions of this model have been extended. This dimension increase is intended to enhance the Electromagnetic Susceptibility (EMS) performance

Physical Differences

  • Front Panel Changes - The port layout is updated in CBS110-16T and CBS110-24T/24PP models for easier identification and use.

  • Chassis Dimensions - CBS110-5T-D has an extended overall dimension for improved EMS.

  • Visual Identification - New models can be visually distinguished by their updated port arrangement and, for CBS110-5T-D, a larger physical size.

CBS110 -24PP

  • Top switch is the new CBS110-24PP

  • Bottom switch is the old CBS110-24PP

  • For ASIC update,the front ports in old CBS110 will update to 24*GE+2*Combo​

CBS110-5T-D

  • Top switch is the old CBS110-5T-D, tan74-xxx-01

  • Bottom switch is the new CBS110-5T-D, tan 74-xxx-04

Frequently Asked Questions

Q. 

How can I visually confirm I have the new hardware?

A. 

Check port arrangement and, for CBS110-5T-D, the chassis size. You can also verify the VID on the product label.

Note


An RMA replacement will be using the new models.
