Use this procedure to remove or replace the air moving device (AMD) - B01 and B02 in Models 270, 800,
and 810.
The Models 270, 800, and 810 may be housed in a FC 0551 frame. The upper and lower system units are
placed on rails in the frame. If you are working on the upper or lower unit, follow these instructions and
access the internal parts by opening the front cover and sliding the system unit out on its rails.
To remove or replace the air moving device - B01 and B02:
1. Power off the system. See Power on/off the system and logical partitions.
2. Disconnect the power cord. On Models 270, 800, and 810 with a system unit expansion attached,
disconnect both the system line cord and the expansion unit line cord.
3. Remove the front cover. See Models 270, 800, and 810 - Covers.
4. Remove the AMDs by pulling out on the two top side fasteners and pivoting them toward you.
5. Unplug the cable.
6. Reverse this procedure to install the AMDs. When installing the AMDs, be sure the cardboard is placed
between the two fans.
This
ends the procedure.
