About the Cisco Compute Module

The CGR Compute Module is a modular, hardened server that can be installed in CGR 1000 routers. The compute module functions as a fog computing node at the edge of the network.

The x86-based multi-core compute module hardware incorporates the industry standard COM Express (COMEe) module, referred to in this document as COMe sub-module. The sub-module fits inside the compute module enclosure, which occupies one slot of the host CGR. The CGR1120 and CGR1240 can each host one compute module.

Compute Module Product SKUs lists product options for the Compute Module.

Software Requirements

To install and support the Cisco CGR 1000 Compute Module software on the CGR 1000 Series routers, ensure the software requirements in System Requirements are met.

Installation Notes

Please read this section and the Limitations and Restrictions section before installing the compute module.

Note: Cisco IOS Release 15.6(3)M2 must be installed in the CGR 1000 Series router to allow installation of a Compute Module. You can find those release notes at the following link:

–In a CGR 1120, you can install the compute module in any slot.

■You cannot insert or remove a compute module from a CGR system that is up and running.

■Install only one Application Hosting Image per compute module.

–Recommended Virtual Machines: Windows 7, Windows 10 or Linux (Ubuntu14.04LTS)

■When installing a 3G/4G module and/or WPAN module in the CGR 1240, reserve the following slots in that system:

–Slot 3 with either the 3G or 4G module
