Cisco 8100 Series Routers Overview

Cisco 8100 Series Routers

The Cisco 8100 Series Routers utilizes Cisco’s new Router-on-Chip (RoC) model to deliver full routing functionality with a single ASIC per router. The RoC architecture is distinguished from System-on-Chip (SoC) switches by supporting large forwarding tables, deep buffers, more flexible packet operations, and enhanced programmability.

Cisco 8102-28FH-DPU-O Smart Switch DPU Adapter

The Cisco 8102-28FH-DPU-O Smart Switch features four Data Processing Unit (DPU) adapters, which are responsible for managing data plane services. Each adapter contains two DPU complexes, resulting in a total of eight DPU complexes in the switch, providing a combined data processing bandwidth of 1.6Tbps. Each DPU complex comprises of AMD DPU chip, 32GB of on board DDR4 memory, 64GB of eMMC storage and a common power management CPLD (complex programmable logic device). Each DPU adapter offers 200Gbps of network bandwidth and supports a variety of network functionalities within the smart switch.

Field Replaceable Units

The router has the following field replaceable units (FRUs):

  • Fan Module - The router features field-replaceable fan modules that are installed into the chassis from the rear. These fan modules are crucial for cooling the system and maintaining proper airflow. Designed with N+1 redundancy, the fan modules ensure reliable performance.

  • Power Supply Unit - The router is equipped with two power supply units (PSUs) that install into the chassis from the rear. These PSUs provide 12V power to the entire system and operate with 1+1 redundancy to ensure continuous and reliable power delivery.

Designed for easy installation and removal, the PSUs support Online Insertion and Removal (OIR) to minimize downtime and maintain system availability.

SSD Card

The router has a removable Solid State Drive (SSD) card. We recommend to remove the SDD card before shipping the hardware for a Return Merchandise Authorization (RMA) request. Removal of the SSD card enforces customer data security while performing an RMA.

You can access the SSD card by using the hatch provided on the top panel. To remove the SSD card, follow the instructions mentioned on the printed label on the hatch.
Figure 22. Remove the Hatch

To remove the SSD card from the Cisco 8102-28FH-DPU-O smart switch, perform these steps:

  1. Remove the screws from the hatch present on the top panel.

    Figure 23. Cisco 8102-28FH-DPU-O- Remove the Hatch
  2. Carefully reach into the chassis and delicately push the clipper cap backward to release the card.

    Figure 24. SSD Card Removal Instructions
  3. Slowly remove the SSD card from the connector.

Airflow Direction

The Cisco 8100 series routers support these configurations:

  • Post-Side Intake (PSI) configuration - the airflow through both the fan trays and power supplies is from the front-side to the rear-side. In PSI configuration, the power and fan modules are in Burgundy color.

  • Post-Side Exhaust (PSE) configuration - the airflow through both the fan trays and power supplies is from the rear-side to the front-side. In PSE configuration, the power and fan modules are in Cisco Safety Blue color.


Note


The PSE configuration is not supported on these routers:

  • Cisco 8111-32EH-O

  • Cisco 8122-64EH-O

  • Cisco 8102-28FH-DPU-O

  • Cisco 8122-64EHF-O



Note


The airflow direction must be the same for all power supply and fan modules in the chassis. Depending upon the required airflow direction, you can change the fan type. You must then also change the power supply.
