IMPORTANT:
If you have ordered an air filter for the router, attach it to the router before rack-mounting the router.
For the air filter installation procedure, see
1. Put the router on the rack shelf, and slide the router, making sure there is enough clearance
between the router and rack posts for installing the mounting brackets.
2. Attach the router horizontally by fastening the mounting brackets to the rack with appropriate
pan head screws. The specifications of pan head screws must satisfy the installation
requirements, and rustproof treatment has been made to their surfaces.
