Figure 45: Lifting an EX8208 Switch Chassis Without Using a Mechanical Lift
4. In a four-post rack, carefully slide the switch onto the adjustable mounting brackets until the
front-mounting brackets attached to the chassis contact the rack rails. The adjustable mounting brackets
ensure that the holes in the front-mounting brackets attached to the chassis align with the holes in the
rack rails.
In a two-post rack, carefully slide the switch over the lip of the power cord tray and into the rack. Push
the bottom of the chassis so that the front-mounting bracket is flush with the front of the rack.
5. Install a mounting screw into each of the open front-mounting holes aligned with the rack, starting
from the bottom.
6. Visually inspect the alignment of the chassis. If the chassis is installed properly in the rack, all the
mounting screws on one side of the rack are aligned with the mounting screws on the opposite side
and the switch is level.
7. After ensuring that the switch is aligned properly, tighten the screws.
