When install a 7500N chassis in a rack that provides adequate clearance for removing front and rear components.
Arista 7500N Quick Start Guide states the Clearance requirements and footprint for switches.
7500R/R2 Line Card Clearance
Since Quick Start Guide mentioned clearance is only for front and rear side, we added more clearance information here in the left and right space for 7500R/R2 Line card as below:
Max width (when ejector open and pull out line card) 7500R/R2
The above 2 diagrams show the clearance of left and right in a rack which is for linecard eject handle when the line card insert and pull out.
7500R3 Line Card Clearance
The below diagram indicates the 7500R3 line card clearance as below:
Max width (when ejector open and pull out line card) 7500R3
The above 2 diagrams show 7500R3 line card eject handle is longer than 7500R/R2 line card for 1.7cm, and the ejector open width is also wider 2.3cm per side.
As a result, it needs 15.7cm clearance from the front of rack post, and 6.3cm clearance from the left/right side of rack post, and the 7500R3 line card max width is 57.2cm.
