After the FXs are installed, mount the AC chassis and the DC chassis in either order.
Note: It is easier to remove the
appropriate side knockouts
from both the AC and DC
chassis before installing either
of them. If needed, the back
knockouts must be removed
before installation.

side knockouts
When installing the AC chassis and the DC chassis:
• Either chassis can be installed rst, the order is not important.
• Only loosely install the four screws securing each chassis. The screws will be tightened later.
