Unpacking and Installing the Chassis

This chapter contains the procedures for installing the router in a rack. The installation is presented in these sections:

Pre-Installation Considerations and Requirements

Before you perform any procedures in this chapter, review these sections:

In particular, observe the guidelines for preventing electrostatic discharge (ESD) damage described in the “Preventing Electrostatic Discharge Damage” section. Use Figure 1-3 as a reference in locating and using the ESD sockets on the front of the router chassis.

For additional safety and compliance information, see the Regulatory Compliance and Safety Information for the Cisco ASR 9000 Series Aggregation Services Routers document that accompanied your router.


Caution This router is not designed to be installed as a shelf-mounted or a free-standing router. The router must be installed in a rack that is secured to the building structure. You must install the router in either a telco-style frame or a 4-post equipment rack.

Installation Overview

A fully-equipped router with two power modules can weigh as much as 37.91 pounds (17.2 kg); an empty chassis weighs 24.69 pounds (11.2 kg). The chassis is designed to be lifted by two persons.

Required Tools and Equipment

Before you begin the rack-mount installation, you must read and understand the information in the “Rack-Mounting and Air Flow Clearance Guidelines” section and have these tools and equipment:

  • ESD-preventive wrist strap
  • Number 1 and number 2 Phillips screwdrivers
  • 1/4-inch (6.35-mm) and 3/16-inch (4.5-mm) flat-blade screwdrivers
  • Tape measure
  • Level (optional)
  • Minimum of 10 slotted binderhead screws (usually provided with the rack) to secure the chassis to the mounting flanges (also called rails ) in the rack. Three screws should be installed on each side of the chassis.

Unpacking the Cisco ASR 9001 Router

Follow these unpacking steps to unpack the Cisco ASR 9001 Router from its shipping container (see Figure 2-1).


Step 1 Cut the packaging tape and open the cardboard shipping container.

Step 2 Remove the accessory box.

Step 3 Remove the packaging material (see Figure 2-1).

Positioning the Router

Use a safety hand truck to move the router to the location where it is being installed in a rack.

Rack-Mounting the Router Chassis

The router chassis is installed in a front-mounted position, as shown in Figure 1-7 for the Cisco ASR 9001 Router chassis.

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


NoteThe PID of the rack mounting kit for mounting a Cisco ASR 9001 Router or Cisco ASR 9001-S Router in a 19-inch two-post rack is ASR-9001-2P-KIT=. The PID of the rack mounting kit for mounting a Cisco ASR 9001 Router or Cisco ASR 9001-S Router in a 19-inch two-post rack is ASR-9001-2P-KIT=.
The PID of the rack mounting kit for mounting a Cisco ASR 9001 Router or Cisco ASR 9001-S Router in a 23-inch two-post rack is ASR-9001-2P-L-KIT=.


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 2-2.


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 the distance 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 17.45 in. (44.32 cm) wide, and fits between the mounting posts on the rack.

Figure 2-2 Verifying Equipment Rack Dimensions

 


 

Installing the Chassis in a 2-Post Rack

To accommodate racks with different hole patterns in their mounting flanges, the chassis rack-mounting flanges have three oblong screw holes on each side.

This section describes how to install the chassis in a 2-post telco-style rack.

Figure 2-3 shows the orientation of the Cisco ASR 9001 Router chassis to the rack posts and components used in the installation.

Use this procedure to install the chassis in the equipment rack:


Step 1 With two people’s aid, lift the chassis into the rack holding top and bottom of the chassis (see Figure 2-4).

Figure 2-4 Correct Lifting Positions

 


Caution Do not grasp air inlet or exhaust when lifting the router chassis.

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 two more 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 Fully tighten both the screws on the chassis mounting flanges on each side to secure the chassis to the rack rails.

Step 6 Fully tighten the two screws on each side bracket flange to secure the brackets to the rack rails.


 

Installing the Chassis in a 4-post Rack

To mount the Cisco ASR 9001 Router chassis in a 4-post open rack, two side brackets must be attached to the chassis and the rear posts (see Figure 2-5).

Figure 2-5 Installing the Cisco ASR 9001 Router Chassis in a 4-Post Rack

 

Supplemental Bonding and Grounding Connections

Before you power on the router for the first time, we recommend that you connect the central office ground system or Network Equipment Building System (NEBS) to the threaded supplemental bonding and grounding receptacles on the router. For more information on supplemental bonding and grounding cable requirements, see the “NEBS Supplemental Unit Bonding and Grounding Guidelines” section.

Use this procedure to attach a grounding cable lug to the router:


Step 1 Insert the grounding screws through the locking washers, and into the threaded grounding receptacle on the Cisco ASR 9001 Router chassis as shown in Figure 2-6.

Step 2 Tighten the grounding screws securely to the receptacles.

Step 3 Prepare the other end of the grounding wire, and connect it to the appropriate grounding point at your site to ensure an adequate earth ground.
