Preparing for Installation
 |
Note In this publication, the term Catalyst 6500 series refers only to the switch chassis
listed in Chapter 1. The Catalyst 6000 series switches are described in a separate
publication, the Catalyst 6000 Series Switch Installation Guide.
|
This chapter describes how to prepare your site for switch installation and contains these sections:
For detailed information about module cabling requirements, refer to the Catalyst 6500 Series Switches Module Installation Guide.
Safety
 |
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030 |
|
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 Before you install, operate, or service the system, read the Site Preparation and Safety Guide. This guide contains important safety information you should know before working with the system. Statement 200 |
|
Warning Voltages that present a shock hazard can exist on inline power circuits if interconnections are made by using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods unless the exposed metal parts are in a restricted access location and users and service people who are authorized to access the location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. |
Site Requirements
This section provides site power requirements for the Catalyst 6500 series switches. You should verify the site power prior to installing the switch. Power requirements vary for each switch; ensure that you verify the site power for the type of switch you are installing.
Environmental Requirements
Planning a proper location for the switch and the layout of your equipment rack or wiring closet is essential for successful system operation. You should install the switch in an enclosed, secure area, ensuring that only qualified personnel have access to the switch and control of the environment. Equipment placed too close together or inadequately ventilated can cause system overtemperature conditions. In addition, poor equipment placement can make chassis panels inaccessible and difficult to maintain.
The switch operates as a standalone system mounted in a rack in a secure wiring closet. It requires a dry, clean, well-ventilated, and air-conditioned environment. To ensure normal operation, maintain ambient airflow. If the airflow is blocked or restricted, or if the intake air is too warm, an overtemperature condition can occur. The switch environmental monitor can then shut down the system to protect the system components.
To ensure normal operation and avoid unnecessary maintenance, plan your site configuration and prepare your site before installation. After installation, make sure the site maintains an ambient temperature of 0° to 40\xb0 C (32° to 104\xb0 F). It is essential to keep the area around the chassis as free from dust and foreign conductive material (such as metal flakes from nearby construction activity) as is possible.
Multiple switches can be rack-mounted with little or no clearance above and below the chassis. However, when mounting a switch in a rack with other equipment, or when placing it on the floor near other equipment, ensure that the exhaust from other equipment does not blow into the intake vent of the chassis.
For the Catalyst 6503, Catalyst 6506, Catalyst 6509, and Catalyst 6513 chassis, cooling air is drawn in through the right side of the chassis and exhausted through the left side of the chassis. For the Catalyst 6509-NEB and Catalyst 6509-NEB-A chassis, cooling air is drawn in through vents above the power supply bay and exhausted through vents at the top of the chassis. Keep all of the vents clear of obstructions, including dust and foreign conductive material, and away from the exhaust ports of other equipment.
"Technical Specifications," lists the operating and nonoperating environmental site requirements for the switches. To maintain normal operation and ensure high system availability, maintain an ambient temperature and clean power at your site. The environmental ranges listed in Appendix A are those within which the switch will continue to operate; however, a measurement that approaches the minimum or maximum of a range indicates a potential problem. You can maintain normal operation by anticipating and correcting environmental anomalies before they exceed the maximum operating range.
Heat dissipation is an important consideration for sizing the air-conditioning requirements for an installation. The power and heat associated with a Catalyst 6500 series switch varies based upon these considerations:
- Chassis type
- Power supply type
- Module types and quantities
- Average switching traffic levels
|
Note We recommend that you maintain a minimum air space of 6 inches (15 cm)
between walls and the chassis air vents and a minimum horizontal separation of
12 inches (30.5 cm) between two chassis to prevent overheating.
|
Unless otherwise noted, the information in Table 2-1assumes worst-case conditions. Typical numbers are approximately 30 percent below the numbers listed in these tables.

Values given are per fan tray. The Catalyst 6509-NEB-A switch chassis ships with one fan tray installed by default. A second fan tray can be installed in the chassis. The power and heat numbers for a chassis equipped with two fan trays are double the values listed.
Card current and power numbers for the WS-X6816-GBIC module are for the base board only. With a WS-F6K-DFC daughter card installed on the base board, the total card current would be 5.94 A (3.84 A + 2.10 A). |
Power Requirements
Follow these requirements when preparing your site for the switch installation:
- In systems configured with two power supplies, connect each of the two power supplies to a separate input power source. If you fail to do this, your system might be susceptible to total power failure due to a fault in the external wiring or a tripped circuit breaker.
- To prevent a loss of input power, be sure the total maximum load on each circuit supplying the power supplies is within the current ratings of the wiring and breakers.
- In some systems, you may use an uninterruptible power supply (UPS) to protect against power failures at your site. Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems like the Catalyst 6500 series switches, which can have substantial current draw fluctuations due to fluctuating data traffic patterns.
Use the information in Table 2-1 to estimate the power requirements and heat dissipation of a Catalyst 6500 series switch based on a given configuration of the switch.
Cabling Requirements
When running power and data cables together in overhead cable trays or subfloor cable trays, be aware of the following caution.

Caution We strongly recommend that power cabling runs and other potential noise sources be located as far away as practical from LAN cabling that terminates on Cisco equipment. In situations, where this type of long parallel cable runs exist which cannot be separated by at least 3.3 feet (1 meter), we recommend that you shield these potential noise sources. To avoid interference, the source should be shielded by housing it in a grounded metallic conduit. |
Also be aware of the following caution concerning the use of Category 5e and Category 6 Ethernet cables.
|
Caution Category 5e and Category 6 cables can store large levels of static electricity because of the dielectric properties of the materials used in their construction. Always ground the cables (especially in new cable runs) to a suitable and safe earth ground before connecting them to the module. |
Power Connection Guidelines for AC-Powered Systems
This section provides the basic guidelines for connecting the Catalyst 6500 series switch AC power supplies to the site power source:
- Each chassis power supply should have its own dedicated branch circuit.
- For North America:
- The 950 W power supply requires a 15 A circuit.
- The 1000 W power supply requires a 15 A or 20 A circuit.
- The 1300 W and 2500 W power supplies require a 20 A circuit.
- The 4000 W power supply requires a 30 A circuit.
- For International:
- Circuits should be sized according to local and national codes.
- If you are using a 200/240 VAC power source in North America, the circuit must be protected by a two-pole circuit breaker.
- The source AC outlet must be within 6 feet (1.8 meters) of the system and should be easily accessible.
- The AC power receptacles used to plug in the chassis must be the grounding type. The grounding conductors that connect to the receptacles should connect to protective earth ground at the service equipment.
Five types of AC-input power supplies are available:
- 950 W—Figure 2-1 shows the different styles of 950 W AC-input power cords that are available for North America or various international locales. Table 2-2 lists the AC-input power cord options, specifications, and Cisco product numbers.
- 1000 W—Figure 2-2 shows the different styles of 1000 W AC-input power cord plugs that are available for North America or various international locales. Table 2-2 lists the AC-input power cord options, specifications, and Cisco product numbers.
- 1300 W—Figure 2-2 shows the different styles of 1300 W AC-input power cord plugs that are available for North America or various international locales. Table 2-2 lists the AC-input power cord options, specifications, and Cisco product numbers. Figure 2-2 also shows the appliance coupler that is attached to the other end of the power cord.
|
Note For North America, the power cord plug types are different for the
1000 W and 1300 W power supplies; for other countries, the plugs
shown in
Figure
2-2 are the same for both 1000 W and 1300 W power supplies.
|
- 2500 W—Figure 2-3 shows the different styles of 2500 W AC-input power cord plugs that are available for North America or various international locales. Figure 2-3 also shows the appliance coupler that is attached to the other end of the 2500 W power supply power cord. Table 2-2 lists the AC-input power cord options, specifications, and Cisco product numbers.
- 4000 W—Figure 2-4 shows the two different styles of AC-input power cord plugs that are available for North America and international locales. Unlike the other power supplies, the 4000 W power supply power cord is hardwired to the power supply and cannot be removed.

The 950 W power supply is for use with the Catalyst 6503 switch only. The other power supplies listed in the table have a different form factor and are not designed to work in the Catalyst 6503 switch chassis.
Some early versions of the 1300 W AC-input power supply were marked as 1800 W. This value refers to the input power rating or maximum system power dissipation of the power supply. The output power of the power supply is 1300 W. Power supplies currently shipping are marked as 1300 W.
You need to ask your local electrical contractor to prepare the NEMA 5-20 power plug.
The 2500 W power supply operating on 110 VAC delivers 1300 W.
You need to ask your local electrical contractor to prepare the NEMA 6-20 or the NEMA L6-20 power plug.
The 4000 W power supply AC power cords are hardwired to the power supply and cannot be removed.
You need to ask your local electrical contractor to prepare the NEMA L6-30 power plug. |
Power Connection Guidelines for DC-Powered Systems
This section provides the basic guidelines for connecting the Catalyst 6500 series switch DC-input power supplies to the site power source:
- All power connection wiring should conform to the rules and regulations in the National Electrical Code (NEC), as well as any local codes.
- For DC power cables, we recommend that you use commensurately rated, high-strand-count copper wire cable. Connection to the DC-input power supply requires one earth ground cable, one source DC (-), and one source DC return (+). The length of the cables depends on your switch location. These cables are not available from Cisco Systems. They are available from any commercial cable vendor.
- The color coding of the source DC power cable leads depends on the color coding of the site DC power source. Typically, green or green and yellow indicate that the cable is a ground cable. Because there is no color code standard for source DC wiring, you must ensure that the power cables are connected to the DC-input power supply terminal block in the proper (+) and (-) polarity. In some cases, the source DC cable leads might have a positive (+) or a negative (-) label. This label is a relatively safe indication of the polarity, but you must verify the polarity by measuring the voltage between the DC cable leads. When making the measurement, the positive (+) lead and the negative (-) lead must always match the (+) and (-) labels on the DC-input power supply terminal block.
Site Preparation Checklist
