Face the front panel, install the
front mounting brackets on both
sides of the router and secure
them with M4 countersunk-head
screws, mount the router on a
rack shelf (skip this step if the
router is not to be mounted on a
rack), and attach the opacity
shield.
Install hex bolts on the chassis
as shown in the figures.
Align the holes on the opacity
shields with the hex bolts.
Press the opacity shields against
the side panels, and use M3
countersunk-head screws to
secure the opacity shields.
Apply tamper-evidence labels to
opacity shields, screws that secure
the opacity shields, field
replaceable units (FRUs), USB
ports, and air vents on interface
cards and filler panels.
