Rack-Mount Kit Overview

This section describes the types of racks for which this rack-mounting kit is intended, and the mounting conﬁgurations that are possible with each type.

Equipment Rack Descriptions

This kit issuitable for mounting the chassis in most 19-inch 2-post, 4-post, or Telco-typeracks. The rack must have at least two mounting posts on which to mount the hardware, and the distance between the mounting holes in the two posts must be 18.31 inches .063 inches (as speciﬁed in the Electronic Industries Association (EIA)–310-C standard).

Figure 1 shows the three types of equipment racks described in this document:

• Figure 1a shows a 2-post rack, which is usually a freestanding enclosed cabinet with two

mounting posts in the front.

• Figure 1b shows a Telco-type rack, which comprises two adjacent mounting posts that are

usually secured to the ﬂoor and/or to an overhead structure.

• Figure 1c shows a 4-post rack, which is usually a freestanding open rack, which can be either

open or enclosed.

Rack-Mount Installation Summary

Following is a summary of the installation procedures required to rack-mount the chassis. This summary is informational and is not intended to replace the actual procedures required to rack-mount the chassis.

Following is a summary of procedures:

1 Read the section “Prerequisites” starting on page 7. 2 Verify that all mounting kit hardware is available. 3 Install the brackets on the rack posts. 4 Attach the spanner bars between the brackets. 5 Attach the chassis ears to the chassis. 6 Install the chassis in the rack.

Throughout these installation procedures, refer to Figure 2, Figure 3, and Figure 4, in addition to the illustrations provided in the speciﬁc installation sections.

Mounting Kit Hardware

The mounting kit comprises two brackets, two chassis ears (each holds two captive grommets), and fasteners (screws). The brackets and ears are identical. On each bracket, the inner side has a turned ledge at the bottom to support the chassis, and shielding to provide electrical isolation between the chassis and the rack. At the front of each bracket is a ﬂange with ﬁve mounting holes at the top and three at the bottom.

Rack-Mount Kit Overview

Each of the two brackets mounts to a rack post with three 10-32 x 5/8-inch, Phillips pan-head screws, which are provided. The front of each bracket attaches to the front of the rack post, and the remainder of the bracket cantilevers off the post. At the bottom of each bracket, a ledge provides a shelf for the bottom sides of the chassis.

A spanner bar on each bracket hooks into the opposite bracket to maintain an exactdistance between the two brackets at both the ends attached to the rack posts and unattached ends. The spanner bars prevent the two brackets from separating. (See Figure 11 on page 19.)

Each of the chassis ears attaches to a side of the chassis with two M4 x 10-mm, Phillips, ﬂat-head screws). When the chassis is in the rack, the mounting strips on the chassis ears attach to the rack-mounting posts with four 10-32 x 5/8-inch, Phillips, pan-head screws. The ledges at the bottom of the brackets support the weight of the chassis. The ears are not weight-bearing ﬁxtures, but prevent the chassis from sliding out of the rack horizontally.

You can attach the ears to either the front or back of the chassis, whichever end you will place at the most accessible end of the rack. For most installations, we recommend that you attach the ears to the interface processor end (rear) so that you can have access to the power supplies, processor slots, and all status LEDs.

Rack-Mount Kit Overview

In Telco-type installations, you can install the chassis so that the ends of the chassis are approximately centered on two posts. Figure 3 shows a typical center-mount installation.

Caution To maintain a safe center of gravity in Telco-type installations (shown in Figure 3), the

front and rear of the chassis are approximately centered on the mounting posts.

Figure 3 Typical Center-Mount Installation

H2296

In a 2-post, 4-post, or Telco-type installation, you can ﬂush-mount the chassis so that the end of the chassis is ﬂush with the rack posts. (When mounting the non-interface processor end, the front is actually recessed 1 inch into the rack to protect the plastic front bezel.) Multiple-chassis rack kits can be stacked in a rack with little or no clearance between the brackets. You can remove the four chassis feet after mounting the chassis in the rack.

Safety Guidelines

Reviewthe following guidelines to help ensure your safety and protect the equipment from damage during the installation.

Warning Before working on a system that has an on/off switch, turn OFF the power and unplug

the power cord. (For translations of this safety warning, refer to the section “Power Disconnection Warning” on page 29.)

Warning Do not touch the power supply when the power cord is connected. For systems with a

power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. (For translations of this safety warning, refer to the section “Power Supply Warning” on page 29.)

Warning Before working on a chassis or working near power supplies, unplug the power cord on

AC units; disconnect the power at the circuit breaker on DC units. (For translations of this safety warning, refer to the section “Power Supply Disconnection Warning” on page 30.)

Warning This unit might have more than one power cord. To reduce the risk of electric shock,

disconnect the two power supply cords before servicing the unit. (For translations of this safety warning, refer to the section “Electric Shock Warning” on page 31.)

Working with Electrical Equipment

When working with any electrical equipment, the following guidelines will help to ensure your safety and protect the equipment. This list does not include all potentially hazardous situations, so be alert.

• Never try to lift the chassis by yourself; two people are required to lift it.

• Always turn all power supplies off and unplug all power cords before installing or removing a

chassis.

• Keep the chassis area clear and dust free during and after the installation.

• Keep tools and chassis components away from walk areas.

• Keep your path clear between the chassis and the rack. When carrying large, heavy equipment

such as the chassis, obstacles such as hand tools, cables, or components not be easily visible and can cause accidents.

Lifting the Chassis Safely

The chassis weighs 76 pounds (34.5 kilograms [kg]) when empty (with no interface processors or power supplies installed) and 145 pounds (65.8 kg) with two power supplies and seven processor modules installed. The chassis is not intended to be moved frequently. Before you install the router, ensure that your site is properly prepared, so you can avoid having to move the chassis later to accommodate power sources and network connections.

Whenever you lift the chassis or any heavy object, follow these guidelines:

• Never attempt to lift the chassis by yourself. The size and weight of the chassis require two

people to safely lift and move it without causing injury or damaging the equipment.

8 Cisco 7000 and Cisco 7507 Rack-Mount Kit Installation Instructions

Prerequisites

• Ensure that your footing is solid and balance the weight of the object between your feet.

• Lift the object slowly; never move suddenly or twist your body as you lift.

• Keep your back straight and lift with your legs, not your back. If you must bend down to lift the

chassis, bend at the knees, not at the waist, to reduce the strain on your lower back muscles. (See Figure 5.)

• Grasp the underside of the chassis exterior with both hands.

Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge

and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies or on the interface processors, or by the plastic panels on the front of the chassis. These handles were not designed to support the weight of the chassis. (For translations of this safety warning, refer to the section “Chassis Lifting Warning” on page 32.)

Prerequisites

Safety with Electricity

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergency

power-off switch for the room in which you are working.

• Disconnect all power and external cables before installing or removing a chassis.

• Do not work alone if potentially hazardous conditions exist.

• Never assume that power is disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes the equipment

unsafe.

• Carefully examine your work area for possible hazards such as moist ﬂoors, ungrounded power

extension cables, and missing safety grounds.

Warning Do not work on the system or connect or disconnect cables during periods of lightning

activity. (For translations of this safety warning, refer to the section “Lightning Activity Warning” on page 34.)

10 Cisco 7000 and Cisco 7507 Rack-Mount Kit Installation Instructions

Prerequisites

When you replace the power supplies, remember to engage all of the safety features on each supply. The power supplies feature the following three safety interlock features:

• A safety interlock on/off switch (see Figure 6) prevents the power supply from being removed

from the chassis when the power supply switch is in the on (|) position. When the switch is on, a metal tab extends into a slot in the chassis. When the switch is turned off (O), the tab retracts into the power supply housing and clears the slot.

• A captive installation screw at the top of the power supply front panel provides electrical

grounding and prevents the power supply from vibrating or sliding out of the bay and dislodging from the power connectors in the backplane.

• A cable retention clip prevents the power supply power cord from being accidentally pulled out

of the power supply socket.

For a complete description of the power supply, refer to the Cisco 7000 Hardware Installation and Maintenance or Cisco 7507 Hardware Installation and Maintenance publications.

Equipment Rack Considerations

This kit is suitable for mounting the chassis in most 19-inch 2-post, 4-post, or Telco-type racks that conform to the EIA-310-C standard. The brackets, which support the chassis, cantileverofftwo rack posts. Youcan mount the chassis with either end approximately ﬂush with the two rack posts, or, in Telco-type installations, you can center-mount the chassis. Before proceeding, reviewtheguidelines in this section and ensure that you have planned your installation carefully to avoid hazards such as top-heavy or unbalanced racks, or cables or equipment that obstruct trafﬁc paths or access to equipment.

Before using a particular rack, check for obstructions (such as a power strip) that could impair access to the processor modules or power supplies at the interface processor end, or to the chassis panels that provide access to the internal ﬁeld replaceable units (FRUs) at the non-interface processor end of the chassis. Figure 7 showsthe chassis footprint and outer dimensions, and the clearance required to remove or install FRUs.
