To install the switch into a 19-inch standard chassis:

four holes of the brackets align to the screw holes, and then use the 
four supplied M4 screws to secure it. 
STEP 2 Repeat the previous step to attach the other bracket to the opposite 
side of the switch. 
STEP 3 After the brackets are securely attached, the switch is now ready to 
be installed into a standard 19-inch rack as shown here.
