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.

Limitations and Restrictions

n Only one compute module can be installed in a CGR 1240 or CGR 1120.

— In a CGR 1240, you must install the compute module in slot 5 and Slot 6 must remain empty to dissipate heat.

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

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

n Install only one Application Hosting Image per compute module.

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

n 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

— Slot 4 for the WPAN module

Table 3 Open Caveats in Release 1.6.0.6

Caveat Number

Description

CSCvi83422

USB unplug/plug and hot swap failed.

This issue is seen when you unplug the USB drive and plug the USB drive back in again on the VM. The VM is not able to detect the USB drive when you remove and plug it back.

Workaround: Deactivate, activate. Then, start the VM to recognize the USB drive.
