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.
The Cisco 8100 series routers include the following variants:
•Cisco 8102-64H - It provides 6.4 Tbps of network bandwidth with dramatically lower power consumption
than contemporary 10 Tbps systems. The Cisco 8102 Router is a fixed port, high density, two rack unit
form-factor router. Supported ports include 64 x 100G QSFP28.
• Cisco 8102-64H-O - It provides 6.4 Tbps of network bandwidth with dramatically lower power
consumption than contemporary 10 Tbps systems. The Cisco 8102 Router is a fixed port, high density,
two rack unit form-factor router. Supported ports include 64 x 100G QSFP28. The Cisco 8102-64H-O
supports the open-source network operating system SONiC (Software for Open Networking in the Cloud).
• Cisco 8101-32FH - It provides 12.8Tbps of network bandwidth. The Cisco 8101-32FH Router is a fixed
port, high density, one rack unit form-factor router. Supported ports include 32 x 400G QSFP-DD. The
functionality and installation of this router is similar to that of Cisco 8201-32FH. The Hardware Installation
Guide for Cisco 8201-32FH is available here.

• Power Supply Unit
Both the FRUs support OIR (Online Insertion and Removal).
Fan Module
The router has three latched fan modules that installs into the chassis from the rear. Fans cool the system and
maintain proper airflow through the system. The fan modules work with N+1 redundancy.

Power Supply Unit
The router has two PSUs that install into the chassis from the rear. The PSUs work with 1+1 redundancy and
the router supports two AC or two power supplies. The PSUs can be:
• AC to DC type - 650W
• DC to DC type - 930W
The PSUs provide 12V power to the entire system.

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.
