level, insert a screw through the top hole
3
in each front
flange of the shelf. Loosely thread the screws into the front mounting rails.
5. Check that the shelf is at the same level on the four mounting rails.
6. Insert a screw through the bottom hole
4
in each front flange of the shelf.
Loosely thread the screws into the front mounting rails.
7. Tighten all mounting screws using a 7 mm nut driver or a 7 mm socket wrench.
8. Route cables down one of the rear rack rails by threading each tie wrap through
a hole in the rail and around the cables. One tie wrap should be located near
the rear of the drive; the other should be located farther down the rack rail.
Tighten cable ties securely around the cables so the cables cannot be pulled
out. Cut off tie wrap excess.
Attention: It is important to install cable ties on the cables! This helps secure
the equipment on the shelf from being accidentally pushed off or from slipping
off the front of the shelf.
The shelf installation is complete. You can now install your equipment on the shelf.
Removing the shelf from the rack
To remove the shelf from the rack, reverse the steps in the installation procedure.
Inspect the Power Cord and Outlet
1. Inspect the power cord plug to ensure that it matches the power receptacle. If it
does not match, see “Power Cords” on page C-1 to determine the appropriate
power cord.
2. Ensure that all associated electrical outlets are properly grounded and that the
circuit breaker is turned on.
