Sides: For a two-post rack installation, allow adequate space for access to the sides of the switch so 
that the front mounting brackets can be attached to the switch.
Selecting Rear Mounting Brackets
To allow installation of the switch in cabinets of different depths, the Summit X650 series switch has 
two sets of rear mounting brackets. Use the bracket that best suits the cabinet depth or rack depth 
where the switch will be installed:
Shorter brackets—cabinets or racks 25 inches to 31 inches (63.5 cm to 76.7 cm) deep
Longer brackets—cabinets or racks 25 inches to 36 inches (63.5 cm to 91.4 cm) deep
For a two-post rack installation, the shorter brackets are recommended.
Installing the Switch in a Two-Post Rack
To install the switch in a two-post rack:
1
Attach an ESD-preventive wrist strap to your wrist and connect the metal end to an appropriate 
ground point on the rack.
2
Using rack-mounting screws suitable for your rack, attach a rear mounting bracket to the back of 
each rack post (
Do not tighten the screws all the way. You should be able to move the brackets against the rack post.
