- Mounting the Cisco ASR 901 10G Router in a 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 ...
- 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).
- Wall-Mounting
- Attaching Brackets for Wall-Mounting
- Step 1 Locate the mounting holes of the router.
- Step 2 Align the wall-mounting bracket with the router and position with the four Number 6-32 x 0.25-inch screws (provided). See Figure 3-5.
- Step 3 Insert the screws (in four places) and tighten using a Number 2 Phillips screwdriver (on each side).
- Step 4 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 Number 6-32 x 0.25-inch mounting screws (two on each side).
- Step 5 Tighten the screws using a 1/4-inch flat-blade screwdriver (on each side).
- Mounting the Router on a Wall
- Step 1 Locate the position where you plan to install the router.
- Step 2 Ensure that there are no obstructions.
- Step 3 Position the router with the ports facing up as in Figure 3-6, or down and align the bracket holes with the holes on the wall and secure with four Number 6-32 x 0.25-inch mounting screws (two on each side).
- Step 4 Tighten the screws using a 1/4-inch flat-blade screwdriver (each side).
- Attaching Brackets for Wall-Mounting
- Connecting the Chassis Ground and Power
- Grounding the Cisco ASR 901 10G Router
- Figure 3-7 Grounding Point
- Step 1 In the accessory kit, locate the 2-hole lug, 2 pan-head Phillips head screws used to attach the lug to the router, and the 6-AWG ground wire. (Lug, screws, and wire are part number 32-0629-01.)
- Step 2 Set the parts aside.
- Step 3 If your ground wire is insulated, use a wire-stripping tool to strip the ground wire to 0.5 inch ± 0.02 inch (12.7 mm ±0.5 mm) for the ring terminal (Figure 3-8).
- Step 4 Slide the open end of the ground lug over the exposed area of the ground wire.
- Step 5 Using a crimping tool (as specified by the ground lug manufacturer), crimp the ground lug to the ground wire (Figure 3-9).
- Step 6 Use a Phillips head screwdriver to attach the ground lug and wire assembly to the front of the router with the two screws from the accessory kit.
- Step 7 Connect the other end of the ground wire to a suitable grounding point at your site.
- Power Connection Compliance
- Wiring the DC-Input Power Source
- Step 1 Switch off the DC power source at the circuit breaker, and place the circuit breaker in the Off position.
- Step 2 Locate the two 3-pin terminal blocks (part number 27-1892-01). The terminal blocks are located in the accessory kit (part number 53-3438-01) shipped with the Cisco ASR 901 10G router.
- Step 3 Plug the 3-pin terminal block into the power connector located on the front side of the router. See Figure 3-10
- Step 4 Repeat Step 3 to attach the other terminal block.
- Step 5 Connect the other end of the power cord to the site DC power source.
- Installing the DC Power Cord Retainer
- Step 1 In the accessory kit, locate the two cable holders and the two pan-head Phillips head screws used to attach the cable holders to the router. (part number of cable holder is 52-0685-01.)
- Step 2 Set the parts aside.
- Step 3 Insert the DC power cord through the cable holder. See Figure 3-11. Repeat this step for the second DC power cord.
- Step 4 Use a Phillips head screwdriver to attach the cable holders to the front of the router with the two screws from the accessory kit. See Figure 3-12.
- Installing the AC Power Cord Retainer
- Step 1 Choose the sleeve size of the power cord retainer based on the thickness of the cord. The smaller sleeve can be snapped off and used for thin cords. See Figure 3-16.
- Step 2 Slide the retainer around the AC power cord, and pass it around the lanced loop on the router. See Figure 3-13.
- Step 3 Slide the retainer through the first latch. See Figure 3-14.
- Step 4 Slide the retainer through the other latches to lock it. See Figure 3-15.
- Step 5 (Optional) Use the small sleeve for thin power cords. Use the small sleeve to provide greater stability for thin cords. Detach the sleeve, and slide it over the power cord. See Figure 3-16.
- Step 6 Secure the AC power cord by pressing the retainer. See Figure 3-17.
- Installing and Removing SFP Modules
- Installing SFP Modules
- Figure 3-18 SFP Module with a Bale-Clasp Latch
- Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.
- Step 2 If the SFP module that you are using has the markings, use them to identify the top side of the module.
- Step 3 Align the SFP module in front of the slot opening.
- Step 4 Insert the SFP module into the slot until you feel the connector on the module snap into place in the rear of the slot (see Figure 3-19).
- Step 5 For fiber-optic SFP modules, remove the dust plugs from the optical ports, and store them for later use.
- Step 6 Insert the cable connector into the SFP module:

- Step 3 Unlock and remove the SFP module, as shown in Figure 3-20.
- Step 4 Grasp the SFP module between your thumb and index finger, and carefully remove it from the module slot.
- Step 5 For fiber-optic SFP modules, insert a dust plug into the optical ports of the SFP module to keep the optical interfaces clean.
- Step 6 Place the removed SFP module in an antistatic bag or any other protective casing.
