A fan cage is at least adapted to a first fan and a second fan smaller than the first fan. The fan cage includes a cage body and an adjustment member. The cage body defines a first accommodation portion in a size fitting the first fan. The adjustment member is movably disposed on the cage body and switchable between a laid down status and an upright status within the first accommodation portion. When the adjustment member is in the upright status, the adjustment member is upright in the first accommodation portion so that the adjustment member and the cage body together define part of the first accommodation portion as a second accommodation portion in a size fitting the second fan.

A passive oscillation damper (8), in particular for a switch cabinet (2), includes a supporting structure (12) having a longitudinal direction (y) and a transverse direction (x) and with a central oscillating mass (14) mounted by means of spring elements (20, 22, 24, 26) so as to be able to oscillate in the longitudinal direction (y) and in the transverse direction (x). At least one peripheral oscillating mass (40, 42) is mounted on the central oscillating mass (14) so as to be slidable in the longitudinal direction (y) and to be movable relative to the central oscillating mass (14). At least one peripheral oscillating mass (44, 46) is mounted on the central oscillating mass (14) so as to be slidable in the transverse direction (x) and to be movable relative to central oscillating mass (14).

The invention relates to an extension kit for an IT equipment cabinet having two vertical profiles, two transverse profiles and four depth profiles. The two vertical profiles and the two transverse profiles form a rectangular frame, wherein each depth profile is fastened to the frame with one of its ends. In addition, two adapter profiles are provided, which are arranged parallel to the vertical profiles on the other ends of the depth profiles. These are designed to be fastened to an IT equipment cabinet to extend a depth of the cabinet without affecting its height or width.
