A sealing grommet, particularly for data centers and the like, formed of one or a pair of U-shaped frame sections, each co-molded with a thermoplastic elastomeric seal of corrugated wave form, with corrugated edges of the seals exposed at the open sides of the U-shaped frames. The hole of the supporting sleeve is penetrated by a fixing pin that is insertable into a carrier so as to fix the component on a carrier. The controller is configured to control an engine so that an upper limit value of an output torque of the engine when the low-load conditions are satisfied is made less than when the low-load conditions are not satisfied. The device communicates, via the local forwarding function, first traffic with a particular local device of the local devices, and communicates, via the global forwarding function, second traffic with a particular global device of the global devices.
