To install the firewall in a 19-inch rack:

Make sure the rack is sturdy and reliably grounded.
2.
Wear an ESD wrist strap and unpack the firewall and accessories.

Use a mounting bracket and a slide rail to mark the cage nut installation positions on the front
and rear rack posts, respectively. Four cage nuts are required on each front rack post and two
are required on each rear rack post.

Install cages nuts at the marked positions.

6.
Use the provided M4 screws to attach the mounting brackets and chassis rails to both sides of
the firewall.
The firewall provides multiple installation positions for chassis rails. Install chassis rails to the
appropriate positions and make sure the front ends of the slide rails can reach out of the chassis
rails after the firewall is installed in the rack.
