Procedure
Step 1
Find the physical location of the 7HU shelf in the rack which is to be
connected to the external power source.
Step 2

(e.g. Power A) and find the physical location of the associated termi-
nal block on the rear panel.
Step 3
Select the appropriate cable set, and verify:
a) the cable length is correct for connection between the power
source and the shelf;
b) the wires on both ends of this cable are assembled with the
proper terminals;
c) the terminals are in good order and they are securely fixed to the
wire ends.
