front
Telco-type rack—Two adjacent mounting posts that you must secure to the floor or
an overhead structure
Four-post rack—A freestanding open rack, either open or closed
The rack must have at least two mounting posts.
The distance between the mounting holes in the two posts must be 18.31 inches ±.063

Do not use an enclosed rack for ERX7xx models or the ERX310 router. It does not provide
adequate ventilation.
