brackets are securely fastened. For more information, see the Attaching Brackets to the Router section.
Procedure
Step 1
Locate the equipment rack position where you plan to install the router.
Step 2 Verify that there are no obstructions and ensure that the equipment rack is stabilized.
Step 3
Determine whether you are mounting the router on a 19-inch, 23-inch, or an ETSI rack. Rack-Mounting
Brackets figure shows the types of mounting brackets.
Step 4
Determine the mounting position (Front-, Mid-, or Rear-mounting) of the router. (For 19-inch racks, see
Attaching Brackets for 19-Inch Racks section. For 23-inch racks, see Attaching Brackets for 23-Inch Racks
section. For ETSI racks, see Attaching Brackets for ETSI Racks section.)
Step 5
Locate the mounting holes of the router.
Step 6 Align the rack-mounting bracket with the router and position with the four #6-32 x 0.25-inch screws (provided).
Step 7
Insert the screws (four places) and tighten using a Number 2 Phillips screwdriver (each side).
Step 8 Position the router in the equipment rack lining up the bracket holes on the router with the holes on the rack
and secure with four #6-32 x 0.25-inch mounting screws (two on each side).
Step 9 Tighten the screws using a 1/4-inch flat-blade screwdriver (each side). The recommended maximum torque
