Fan
When removing the fan, do not tilt the fan too much to any one side
The post that steadies the fan is delicate and will breakif too much pressure is exerted on it.
Take care in removing the fan, it should be done as vertically as possible.
NOTE: The tape used to secure the fan is not ordinary tape, but a
special tape with safety characteristics.
This tape is part of the Mylar FRU P/N 05K4881 (12J0514).
If you need to replace the fan, besides the new fan, you need to get from the Mylar FRU the following:
the tape mentioned above, two sponge strips to stick on the sides of the fan, and a double-sided
adhesive tape to attach on the underside of the fan. Refer to the old fan.
The fan cable should follow the path shown in the figure. If the fan
cable gets pressed or weighed down and is damaged, the chassis might get short-circuited as a result.
When removing the fan, do not tilt the fan too much to any one side.
