Abstract

An aseismic (earthquake-secure) server rack is fastened to an earthquake frame in order to increase rigidity and is fixed to the floor at least via the earthquake frame.

Claims

1. An aseismic server rack system, comprising:

A server rack comprising a substantially cuboidal serverrack-frame forming a full cabinet structure with an essentially rectangular base frame, corner pillars and an essentially rectangular upper frame, wherein;

the serverrack-frame comprises a front side and a rear side opposite to the front side;

the rear side and the front side comprise hinges for holding a door of the server rack system; and

the serverrack-frame is capable of being fixed to a floor; and

an earthquake frame including lugs for being fixed to the floor separately from the serverrack-frame and including at least one hinge configured to hold a door of the server rack system,

wherein the earthquake frame is arranged on the rear side or the front side of the serverrack-frame and fixed thereto over an entire perimeter thereof such that a depth of the server rack is increased and the serverrack-frame of the server rack is strengthened.

2. An aseismic server rack system, comprising:

a server rack comprising a substantially cuboidal serverrack-frame forming a full cabinet structure with an essentially rectangular base frame, corner pillars, and sides between the pillars, wherein

the sides of the serverrack-frame comprise a front side and a rear side opposite to the front side; and

an earthquake frame capable of being fixed to a floor, the earthquake frame including at least one hinge configured to hold a door of the server rack system,

wherein the earthquake frame is arranged on the rear side or the front side of the serverrack-frame and fixed thereto over an entire perimeter thereof such that a depth of the server rack is increased and the serverrack-frame of the server rack is strengthened.

3. The aseismic server rack system as claimed in claim 2, wherein the server rack is screwed to the earthquake frame.

4. The aseismic server rack system as claimed in claim 2, wherein the earthquake frame is fastened to a rear side of the server rack.

5. The aseismic server rack system as claimed in claim 2, wherein the earthquake frame comprises at least one cable aperture for vertical and/or horizontal cabling.

6. The aseismic server rack system as claimed in claim 2, wherein the earthquake frame has a same cross sectional dimension as the server rack such that, after being fastened to the server rack, the earthquake frame extends a depth of the server rack.

7. The aseismic server rack system as claimed in claim 2, wherein the earthquake frame is configured to be screwed to the floor with lugs.

8. The aseismic server rack system as claimed in claim 2, wherein the base frame of the server rack includes at least one bore for receiving an anchor for screwing the base frame to the floor.

9. The aseismic server rack system as claimed in claim 8, wherein both a front side and a rear side of the server rack are fixed to the floor via the base frame.

10. The aseismic server rack system as claimed in claim 2, further comprising at least one spacer disposed between the server rack and the floor.

11. An aseismic server rack system, comprising:

a server rack comprising a substantially cuboidal serverrack-frame forming a full cabinet structure with an essentially rectangular base frame, corner pillars, and sides between the pillars, wherein;

the sides of the serverrack-frame comprise a front side and a rear side opposite to the front side; and

the rear side and the front side comprise hinges for holding a door of the server rack system; and

an earthquake frame capable of being fixed to a floor, the earthquake frame including at least one hinge configured to hold a door of the server rack system,

wherein the earthquake frame is arranged on the rear side or the front side of the serverrack-frame and fixed thereto over an entire perimeter thereof such that a depth of the server rack is increased and the serverrack-frame of the server rack is strengthened.
