Positioning the Router

Positioning the Cisco ASR 9010 Router, Cisco ASR 9006 Router, and Cisco 9904 Router

Use a safety hand truck to move the Cisco ASR 9010 Router, Cisco ASR 9006 Router, or Cisco ASR 9904 Router router to its final location for rack installation.

Positioning the and Cisco ASR 9922 Router and Cisco ASR 9912 Router

TheCisco ASR 9922 Router and Cisco ASR 9912 Router and each ship in a carton similar to the CRS-1 16-Slot shipping carton. Each chassis is installed in a shipping rack used only for shipping purposes. Remove the chassis from the shipping rack before installing it into the rack.

To prepare the 19-inch 45-RU rack:


Step 1 Install the two guide rails onto the bottom of the rack.

The guide rails are included with the ASR-9922-ACC-KIT and ASR-9912-ACC-KIT accessory kits. Each accessory kit ships with the chassis and includes the guide rails, grounding lug, associated hardware, and a warranty card.

Step 2 Use screws to fasten these two guide rails onto the front and rear rails of the rack.

The two guide rails at the bottom of the rack (see Figure 2-8) have six holes (three per rail) that accommodate 12-24 or M6 screws. If you are using smaller 10-32 screws, you must use bushings to fit the larger holes (see Figure 2-13).

Figure 2-13 One 10-32 Screw with Bushings in Guide Rail Holes

 


Note Delrin bushings with part number 17234-D-1 can be obtained from ASM at www.accuratescrew.com.


Step 3 Remove the shipping carton, plastic covering, rear brackets, attachment screws and bolts, shipping rack bar, and any cosmetic accessories included with the chassis.

Step 4 Use a scissors jack to remove the chassis from the shipping rack. Place a pallet jack next to the chassis inside the shipping rack and push/pull the chassis onto the pallet jack for transport to the rack.


Caution Tilt the chassis only when absolutely necessary. The chassis is large and heavy. If it were to fall, it could cause harm to itself and its surroundings. Before attempting to tilt the chassis, reduce the weight of the system by removing all of the components in the chassis. The chassis should then be tilted in a direction so that the rear of the chassis is facing downward. The distance the chassis travels without its packaging should be as short as possible.

Step 5 On the rear of the chassis is an integrated handle which is used to pull the chassis from the pallet jack into the rack where the chassis is to be installed. Position the chassis so that the rear handle is facing the front of the rack.

Step 6 From the rear of the rack, pull the chassis by the handle into the rack, making sure that the chassis sits on top of the guide rails in the rack.

Step 7 Once the chassis is pulled into the rack and sits on top of the guide rails, use screws to fasten the chassis to the rack.


 

Removing Components Before Installing the Chassis

The Cisco ASR 9000 Series Routers are designed to be lifted for mounting into a rack. To reduce the weight of the system, you must remove some of the components before attempting to mount it into the rack.

Removing Power Modules

The power modules for the Cisco ASR 9000 Series Routers are shipped separately. If you need to remove an AC or DC power module at a later time, see the “Removing and Replacing Power System Components” section.

Removing Fan Trays


Note If an accessory grill or fan tray cover is installed on the front of the router, you must remove it first.

The router chassis is installed in a front-mounted position, as shown in Figure 1-18 for the Cisco ASR 9010 Router, Figure 1-19 for the Cisco ASR 9006 Router, Figure 1-20 for the Cisco ASR 9904 Router, Figure 1-26 for the Cisco ASR 9922 Router, and Figure 1-27 for the Cisco ASR 9912 Router.

In a front-mounted position, the chassis rack-mounting flanges are secured directly to the rack posts.


Note The Cisco ASR 9922 Router and Cisco ASR 9912 Router are designed to mount in only 4-post racks.


Verifying Rack Dimensions

Before you install the chassis, measure the space between the vertical mounting flanges (rails) on your equipment rack to verify that the rack conforms to the measurements shown in Figure 2-33.


Step 1 Mark and measure the distance between two holes on the left and right mounting rails.

The distance should measure 18.31 inches ± 0.06 inches (46.5 cm ± 0.15 cm).


Note Measure for pairs of holes near the bottom, middle and top of the equipment rack to ensure that the rack posts are parallel.


Step 2 Measure the space between the inner edges of the left front and right front mounting flanges on the equipment rack.

The space must be at least 17.7 inches (45 cm) to accommodate the chassis, which is approximately 17.50 inches (44.45 cm) wide and fits between the mounting posts on the rack.

Figure 2-33 Verifying Equipment Rack Dimensions

 


 

Installing the Chassis in a 2-Post Rack

This section describes how to install the chassis in a 2-post telco-style rack. Two people can lift an empty router chassis using the handles on the sides. To accommodate racks with different hole patterns in their mounting flanges, the chassis rack-mounting flanges have three groups of eight oblong screw holes on each side.


Caution An empty chassis weighs approximately 150 pounds (68 kg). You need two people to slide the chassis into the equipment rack safely.

Figure 2-34 shows the orientation of the Cisco ASR 9010 Router chassis to the rack posts (3” or 6” channel width) of an industry-standard 2-post rack and components used in the installation.

Step 2 Position the chassis until the rack-mounting flanges are flush against the mounting rails on the rack.

Step 3 Hold the chassis in position against the mounting rails while the second person finger-tightens a screw to the rack rails on each side of the chassis.

Step 4 Finger-tighten the screws to the rack rails on each side of the chassis. Space the screws evenly between the top and bottom of the chassis.

Step 5 (Optional) For optional earthquake protection for the Cisco ASR 9010 Router or Cisco ASR 9006 Router, two side brackets must be mounted to the chassis for attachment to the posts (5” channel width) of a GR-63 Zone 4 Seismic 2-post rack (see Figure 2-35).

a. Attach the side brackets to the left and right side of the chassis by finger-tightening five screws through each bracket into the chassis.

b. Attach the side bracket front flanges to the rack posts by finger-tightening four screws through each bracket flange into the mounting rails of the rack.

c. Fully tighten the five screws on each side bracket to secure the brackets to the chassis.

d. Fully tighten the four screws on each side bracket flange to secure the brackets to the rack rails.

Step 6 Fully tighten all five screws on the chassis mounting flanges on each side to secure the chassis to the rack rails.


 

Installing the Chassis in a 4-post Open Rack

To mount the Cisco ASR 9010 Router, Cisco ASR 9922 Router or Cisco ASR 9912 Router chassis in a 4-post open rack, two side brackets must be attached to the chassis and the rear posts. See Figure 2-40 for the Cisco ASR 9010 Router and Figure 2-43 for the Cisco ASR 9922 Router and Cisco ASR 9912 Router.

To mount the Cisco ASR 9006 Router (see Figure 2-41) or Cisco ASR 9904 Router (see Figure 2-42) in a 4-post open rack, extra brackets are not required.

Preparing the 19 Inch 45-RU Rack

To prepare the 19 Inch 45-RU rack that will contain either the Cisco ASR 9922 Router chassis or Cisco ASR 9912 Router chassis:


Step 1 Install the two guide rails into the bottom of the rack (see Figure 2-43).

The two guide rails at the bottom of the rack are included in the ASR-9922-ACC-KIT and ASR-9912-ACC-KIT accessory kits. Use screws to fasten these two guide rails into the front and rear rails of the rack.

The two guide rails have six holes (three per rail) that accommodate 12-24 or M6 screws. If you want to use smaller 10-32 screws, you must use them with bushings to fit the larger holes (see Figure 2-13). The bottom rail is keyed to the EIA mounting hole pattern. Install the rails at the first RU location. The rear rack mount brackets are installed by aligning the bracket mounting holes to the holes on the rear cover of the chassis.

Step 2 Use a scissors jack to remove the chassis from the shipping rack. Place a pallet jack next to the chassis inside the shipping rack and push/pull the chassis onto the pallet jack for transport to the rack.

Step 3 On the rear of the Cisco ASR 9922 Router is an integrated handle that is used to pull the chassis from the pallet jack into the rack where the chassis is to be installed.

a. Position the chassis so that the rear handle is facing the front of the rack.

b. From the rear of the rack, pull the chassis by the handle into the rack, making sure that the chassis sits on top of the guide rails in the rack.

Step 4 On the Cisco ASR 9912 Router, the handles are on the sides of the chassis. Once the chassis is pulled into the rack and sits on top of the guide rails, use screws to fasten the chassis to the rack.

Figure 2-73 Mounting the Cisco ASR 9904 Router Chassis in a 23-Inch Rack

 

Step 7 Tighten the remaining loose screws to complete the installation. Torque the 8-32 screws to 18 in-lb and the 12-24 screws to 41 in-lb.

Figure 2-74 shows the router chassis with the air baffle installed in a 2-post 23-inch rack.

Figure 2-74 Cisco ASR 9904 Router Chassis with Air Baffle in 2-Post 23-Inch Rack

 

An electrical conducting path must exist between the product chassis and the metal surface of the enclosure or rack in which it is mounted, or to a grounding conductor. The chassis has two grounding points on each side of the baffle, however only one ground is required. The other will be grounded through the top and bottom air deflectors. Figure 2-75 shows the baffle ground location on the chassis.

You can ground the baffle by either attaching a grounding lug to the chassis (see the “NEBS Supplemental Unit Bonding and Grounding Guidelines” section), or by using thread-forming mounting screws to establish a metal-to-metal contact. If you are using screws, remove any paint or other non-conductive coatings on the surfaces between the mounting hardware and the enclosure or rack. Clean all surfaces and apply an antioxidant applied before the installation.

Step 2 Attach the left and right hinge brackets to the chassis using three screws (M4 thread) for each bracket. Tighten the screws to a torque of 11 in-lb (1.20 N-m). The L-shaped brackets should align with the holes in the cable management tray from which you removed the screws.

Step 3 Secure the L-shaped brackets to the chassis and cable management tray by re-inserting and tightening the cable management tray screws you removed.

Step 4 Align the exhaust air deflector at the rear of the chassis behind the top fan tray outlets (see Figure 2-80), and use a screwdriver to tighten the two screws, one on each side of the deflector. The deflector’s measurements are width 17.48” x height 4.72” x depth 5.21” and deflects the outgoing exhaust air.
