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 with 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 (see
▌5▐
in Figure 30) through
a hole in the rail and around the cables. One tie wrap must be located near the rear of the 3580; the
other must 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.
The shelf installation is complete. You can now install your equipment on the shelf.
