Installation process
Step 1: Check the grounding and stability of the rack. Use the screws to fix the mounting ears at both
sides of the front panel or the rear panel of the router.
Step 2: Put the router in a rack tray. For MSR 20-40 routers, use dedicated ears mounted on the rear
panel if no tray is available. Depending on the actual situation, slide the router along the chassis guides
to an appropriate place.
Step 3: Fasten the mounting ears with the recess screws to fix the router in the rack horizontally and
firmly. The specifications of recess screws should satisfy the installation requirements and the surface
of the screws should be anti-rust.
