A device-frame (101) for telecommunication devices (117) comprises a body- section (104) that comprises plug-in unit places for the telecommunication devices. The device-frame further comprises an air-guide element (107) movably supported to the body-section so that a flow area of an air-intake of the device-frame is increasable by changing the position of the air-guide element with respect to the body-section so that the height of the device-frame increases and the flow area is decreasable by changing the position of the air-guide element so that the height of the device-frame decreases. The height of the device-frame can be adjusted to be smaller in cases where the circumstances are not the most demanding from the viewpoint of the cooling and therefore, in less demanding circumstances, it is possible to have more device-frames in a rack. |
