Before You Begin Rack Installation - Juniper ACX5448-D Hardware Manual

You can mount an ACX5400 router in a four-post 19-in. rack or cabinet using the mounting kit provided
with the device.
For four-post rack or cabinet installations, the mounting kit contains two front-mounting rails with two
matching rear-mounting blades. This configuration allows either end of the router to be mounted flush
with the rack and still be adjustable for racks with different depths.
The front and rear rack rails must be spaced between 28 in. (71.1 cm) and 36 in. (91.4 cm) front to back.
