The rear modules are not designed for adding with the switch on, so even if that is not the cause of this, unplugging the switch before adding modules is the recommended method for adding them. EnvMontask and BoxReq are for monitoring fans and temperature, so adding a module could be causing this. With this being a PoE switch it could be a device drawing too much power.   Reloading probably is the best first step to take. Beyond that, removing the module and updating firmware would be the next steps. It probably is not a connected device, but disconnecting cables and seeing if it causes a change in CPU usage could also be helpful.
Hi All, One of our Powerconnect Switch has very high CPU usage about 96% average, There are only two processes that generate this usage: envMonTask and boxs Req each about 46-48% [IMAGE] [IMAGE]  As they are monitoring processes I am not sure what can cause such cpu usage and how to fix it, I remember recently 10Gb module was installed when the switch was on and after that nothing has been rebooted, could that be the reason?
