2-6 Setting Up The DAU
Installing the Rails
Note: In the following procedure the left rail is shown as
viewed from the front of the rack. Right rail installation
procedures also apply to installing the right rail.
1. Rail support hooks are marked (L) for the left hook and (R) for right hook.
With the left rail support hook (L) facing towards the inside of the cabinet,
hang the top tab of the rail support hook on the square hole of the rack front
rail to which the DAU will be mounted. Be sure the counter-sunk holes in
the rail support hook are centered within the square holes of the rack front
vertical rail. Also, the hook projections on the rail support hooks should be
facing upwards. See Figure 2-2.
