Throughout this publication, safety warnings appear in procedures that can harm you if performed incorrectly. A warning symbol precedes each warning statement.
Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Warning To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit. Statement 1032
This document describes how to install Catalyst 4500 series switches in a two-post rack using the optional brackets. For first-time installations, perform the procedures in the following sections in the order listed: For all other information regarding installing a Catalyst 4500 series switch, refer to the Catalyst 4500 Series Installation Guide at:
Rack-Mounting the Switch
This rack-mount kit is used for mounting the switch in a standard 23-inch (58.4 cm) equipment rack with two unobstructed outer posts. This kit is not suitable for racks with obstructions (such as a power strip) that could impair access to the field-replaceable units (FRUs) of the switch.
Required Installation Tools
You will need the following tools and equipment to install the chassis in a rack:
•Number 1 and number 2 Phillips screwdrivers to tighten the captive installation screws on most systems
•3/16-inch flat-blade screwdriver for the captive installation screws on the supervisor engine and switching modules on some systems
•Antistatic mat or antistatic foam in case you need to remove switching modules to troubleshoot the installation
•Your own electrostatic discharge (ESD) grounding strap or the disposable ESD strap included with the system
Rack-Mounting Catalyst 4500 Series Switches
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:
•This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
•When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
•If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006
Follow these steps to install a Catalyst 4500 series switch in a rack:
Step 1 Prepare for installation as follows:
a. Place the chassis on the floor or on a sturdy table as close as possible to the rack. Leave enough clearance to allow you to move around the chassis.
b. Open the rack-mount kit and check the component checklist in Table 1 to verify that all parts are included.
Table 1 Rack-Mount Kit Checklist
Quantity Part Description
Center rack mounts
M4 Phillips pan-head screws
12-24 x 3/4-inch Phillips binder-head screws
Note Some equipment racks provide a power strip along the length of one of the rear posts. If your rack has this feature, consider the position of the strip when planning fastener points. Before installing the brackets on the chassis, determine whether to install the chassis from the front or the rear of the rack.
Step 2 Install the brackets, which connect the chassis to the rack, as follows:
a. Remove the screws from the front of the switch side-cover panels.
b. Attach the brackets to the left and right sides of the switch using the M4 Phillips pan-head screws provided in the rack-mount kit.
Note Be sure to install the bracket with the filter element on the side of the switch opposite from the fan tray, as is shown in the illustrations. It is possible to reverse the brackets and install the filter on the wrong side, losing the advantage of having the filter.

Figure 3 Center Mount Brackets on the Catalyst 4507R Switch
Figure 4 Center Mount Brackets on the Catalyst 4510R Switch
c. Attach the filters. To attach the front filter, slide the bottom of the filter into the bracket, pull the tab down, and push it into the center mounting bracket. Slide the rear filter in parallel to the chassis from the rear of the switch. The filters should cover the air intake grill of the switch.
Note The filter should be replaced every 3-6 months, or more often if needed.
d. Attach the cable guide, if needed, using the M3 screws provided in the cable management kit. The cable guide attaches to the mounting bracket. Attach the cable guide to the right side of the switch to prevent the cables from obscuring module LEDs.

Figure 8 Attaching the Cable Guide to the Catalyst 4510R Switch
Step 3 Install the chassis in the rack as follows:
a. Insert the rear of the chassis between the mounting posts.
b. Align the mounting holes in the bracket with the mounting holes in the equipment rack.
c. Secure the chassis using at least six (three per side) 12-24 x 3/4-inch screws through the elongated holes in the L bracket and into the threaded holes in the mounting post.
d. Use a tape measure and level to ensure that the chassis is installed straight and level.

Step 4 Make sure that the ejector levers are completely closed and the supervisor engine and switching modules are installed securely.
Step 5 Tighten any loose captive installation screws on the supervisor engine and the switching module.
Step 6 Connect the switch to an appropriate ground. Refer to the "System Ground Connection Guidelines" section. The system must have a ground connection before power is supplied to the switch.
Step 7 Connect the power supply cords.
The switch comes on when the cords are connected and the power switches (if present) are turned on.
This completes the installation of the Catalyst 4500 series switches.
System Ground Connection Guidelines
A grounding pad with two system (earth) grounding holes is provided in an enclosure near the left power supply on the Catalyst 4500 series switches. See Figure 13 for the location of the grounding holes on the Catalyst 4503 switch, Figure 14 for the location on the Catalyst 4506 switch, Figure 15 for the location on the Catalyst 4507R switch, and Figure 16 for the location on the Catalyst 4510R switch.

Parts and Required Tools
Note The parts and required tools described in this section are not available from Cisco Systems.
To make an adequate grounding connection, you will need the following parts and tools:
•Grounding lug—The grounding lug must have two grounding holes.
•Two M4 (metric) hex-head screws.
•One grounding wire (6 AWG recommended)—The length of the grounding wires depends on the location of your switch within the site and its proximity to proper grounding facilities.
•Number 2 Phillips screwdriver.
•Crimping tool—This tool must be large enough to accommodate the girth of the grounding lug when you crimp the grounding cable into the lug.
Connecting System Ground
This section describes how to connect the Catalyst 4500 series switches to earth ground. The system ground connection is required if FXS modules are installed or if this equipment is installed in a US or European Central Office.You must complete this procedure before connecting system power or turning on your switch.
To attach the grounding lug and cable to the grounding pad on your Catalyst 4500 series switch, follow these steps:
Step 1 Using a wire-stripping tool, remove approximately 0.75 inches (19 mm) of the covering from the end of the grounding wire.
Step 2 Insert the stripped end of the grounding wire into the open end of the grounding lug (Figure 17).
Step 3 Using a crimping tool, secure the grounding wire in place in the grounding lug.
Step 4 Locate the grounding pad on the switch.
See Figure 13 for the location of the grounding holes on the Catalyst 4503 switch, Figure 14 for the location on the Catalyst 4506 switch, Figure 15 for the location on the Catalyst 4507R switch, and Figure 16 for the location on the Catalyst 4510R switch.
Figure 17 Connecting System Ground on the Switch
Step 5 Remove the label that covers the grounding pad.
Ensure that the grounding lug and the attached wire will not interfere with other switch hardware or rack equipment.
Step 7 Tighten the screws to secure the grounding lug to the grounding pad.
