Installation into Cabinet or Rack
Power Up
The shelf and installed units are internally powered by an AC or DC supply. An optional second power
supply can be used for redundant protection.
The dual input power shelves 4202023L6 (AC) and 4202023L8 (DC) provide the user greater redundancy
by allowing the shelf to be powered by two separate AC (or DC) circuits so that service will not be
interrupted upon a single circuit breaker fault. Shelf power inputs can be both AC or both DC, but they
cannot be mixed.

INSTALLATION INTO CABINET OR RACK
The set of brackets supplied with the Smart 16e Shelf can be used for either 19" or 23" applications. For
19" applications, the longer side of the bracket should be flush with the side of the chassis. For 23"
applications, the short side of the bracket should be flush with the side of the chassis.
There are two sets of mounting holes for the brackets on the left and right sides of the Smart 16e Shelf. One
set positions the front of the Smart 16e Shelf in line with the front of the rack. The other set extends the
front of the Smart 16e Shelf beyond the front of the rack.
