Red Hat Fence Agents is a collection of scripts to handle remote power management for several devices. They allow failed or unreachable nodes to be forcibly restarted and removed from the cluster.

fence_eps is an I/O Fencing agent which can be used with the ePowerSwitch 8M+ power switch to fence connected machines. Fence agent works ONLY on 8M+ device, because this is only one, which has support for hidden page feature.
