   b. Remove the server from the rack.
   c. Attach an antistatic wrist strap.
   d. Remove the top cover.
   e. If you are removing the SAS expander board from a server with 2.5-inch storage drives, remove the server’s front cover.
2. Remove fan modules 1 through 4, leaving fan modules 0 and 5 in place.
3. Removing the SAS expander board.
