The fan 110 is installed in the fan bracket 120 to form an integral module, the fan bracket 120 can be inserted into and fixed in the chassis 200, and when the fan 110 fails and the fan module 100 needs to be pulled out of the chassis 200, the fan bracket 120 is pulled out of the chassis 200.

Specifically, as shown in fig. 1, the fan bracket 120 includes: a fixed base plate 121 and a connecting structure.

In this embodiment, the fixing base plate 121 is used for bearing and fixing the fan 110. That is, the fan 110 is disposed on the fixed base plate 121 and fixed to the fixed base plate 121, wherein the fixing manner is not limited. The fan 110 is fixed to the fixing base plate 121 so that the fan 110 can be inserted into or removed from the housing 200 together with the fan bracket 120.

In this embodiment, the connection structure is connected to the fixed base plate 121 for being plugged into the chassis 200.

The interface module 210 is an expansion module of the server, and provides functional interface expansion, and the whole interface module 210 is integrally inserted into the chassis 200 or pulled out of the chassis 200.

When the fan 110 in the server chassis 200 is damaged, the hot plug maintenance process of the fan 110 of the chassis 200 in this embodiment is as follows:

1) the interface module 210 is first pulled out from the rear end of the chassis 200 while the fan module 100 is still in the chassis 200 (the interface module 210 and the fan module 100 are separated).

2) After the broken fan module 100 is pulled out of the chassis 200, a new fan module 100 is inserted into the chassis 200, so that the new fan module 100 operates.

3) After the replacement of the fan module 100 is completed, the interface module 210 is inserted into the server, and the interface module 210 continues to operate.

Therefore, the maintenance process of the whole fan 110 is completed, the server is not powered off in the whole maintenance process, and meanwhile, the whole machine is not disassembled, so that the maintenance efficiency is improved, and the maintenance cost is reduced.

In summary, the fan module can be plugged into the chassis and pulled out of the chassis through the traction interface, so that the maintenance of the fan can be realized without detaching the chassis or powering off, the maintenance efficiency is improved, the maintenance cost is reduced, and the technical problem that the chassis needs to be detached when the fan of the chassis is replaced in the prior art is effectively solved.
