Mounting the Cisco ASR 901 10G Router in a Rack
Perform the steps given below to mount the router into the equipment rack.
Note To secure the Cisco ASR 901 10G router to the equipment rack, you must use the two mounting screws
(provided) for each side or follow your local practices for installing the router into your equipment rack.
Ensure that the rack-mount brackets are securely fastened. For more information, see the “Attaching
Brackets to the Router” section on page 3-3.
Caution To prevent injury, review the “Safety Guidelines” section on page 2-1 and the “Rack-Mounting
Configuration Guidelines” section on page 3-2 before installing the Cisco ASR 901 10G router in the
equipment rack.
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. Figure 3-1 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, page 3-4. For 23-inch racks, see Attaching Brackets for 23-Inch
Racks, page 3-5. For ETSI racks, see Attaching Brackets for ETSI Racks, page 3-6.)
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).
