4.12.4.3  Installing AHAADP01EF-5A/AHAADP02EF-5A on a Backplane 
The connector of AHAADP01EF-5A must be connected to the lower extension port of a backplane. The 
connector of AHAADP02EF-5A must be connected to the upper extension port of a backplane. 
 
 
Points for attention: 
  When users install AHAADP01EF-5A/AHAADP02EF-5A on a backplane, they have to make sure that 
AHAADP01EF-5A/AHAADP02EF-5A is connected to an extension port of the backplane correctly. 
(AHAADP01EF-5A must be connected to the lower extension port of the backplane, and AHAADP02EF-
5A must be connected to the upper extension port of the backplane.) Otherwise, an error will occur if a 
CPU module connects to AHAADP01EF-5A/AHAADP02EF-5A.
