Cold standby hardware & replacement proceduresLast modified on 20 Jun, 2021. Revision 14
- CSB units must match the hardware model of the original unit. For example, a NetWall E10 CSB can only replace another NetWall E10, but it could be one of many E10s.
- CSB units cannot be used as a slave node in a High Availability cluster. HA clusters must contain two standard units with active licenses.
- CSB units are not intended to be used as a standard non-CSB unit since they are set up to only run with the license from the unit they replace.
CSB Video Guide
How a Cold Standby swap works and how to request an RMA for the original faulty unit is shown in the following video: CSB-Swap_.mp4
The CSB service and the CSB replacement process for NetWall hardware is fully described in the “Cold Standby Service” chapter of the PDF entitled “Hardware Replacement Guide for NetWall Firewalls”. This is part of the documentation package for each cOS Core release.
