Install the ACX7348 in a Rack
You can install an ACX7348 router into a two-post rack, four-post rack, or a cabinet. We’ll walk you
through the steps to install an AC-powered ACX7348 router in a two-post rack.
Before you install, review the following:
•"ACX7348 Site Guidelines and Requirements" on page 43
•General Safety Guidelines and Warnings
1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end
of the strap to the ESD point on the device.
2. Grasp both sides of the router, li the router, and posion it in the rack, aligning the holes of the
mounng brackets with the holes in the front post of the rack. Align the boom hole in both the
mounng brackets with a hole in each rack post, making sure that the chassis is level.
3. Secure the mounng brackets to the rack by using four screws appropriate for your rack. Tighten the
screws.
