Site Planning

Note The information in this chapter applies to all Catalyst 6000 family switches unless otherwise noted.

This chapter describes how to prepare your site for switch installation and contains these sections:

• Site Power Requirements

• Switch Ground Connection

• Power Connection Guidelines for AC-Powered Systems

• Site Planning Checklist

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.

For detailed information about cabling requirements, refer to the Catalyst 6000 Family Module Installation Guide.

Note A site planning checklist is provided at the end of this chapter to help you complete all site planning activities before you install the switch.

Site Power Requirements

This section provides site power requirements for the Catalyst 6000 family 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.

For EMI recommendations, refer to the Site Preparation and Safety Guide.

Requirements

Follow these requirements when preparing your site for the switch installation:

• Note that the redundant power option provides a second, identical power supply to ensure that power to the chassis continues uninterrupted if one power supply fails or input power on one line fails. In systems configured with the redundant power option, 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 might 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 6000 family switches, which can have substantial current draw fluctuations due to bursty data traffic patterns.

Power Requirements and Heat Dissipation

Use the information in this section to estimate the power requirements and heat dissipation of a Catalyst 6000 family switch based on a given configuration of the switch. The power requirements might be useful for planning the power distribution system needed to support the switch. Heat dissipation is an important consideration for sizing the air-conditioning requirements for an installation. The power and heat associated with a Catalyst 6000 family switch varies based upon these considerations:

• Chassis type

• Power supply type

• Module types and quantities

• Average switching traffic levels

Unless otherwise noted, the information in Table 3-1 assumes worst-case conditions. Typical numbers are approximately 30 percent below the numbers listed here. See Table 3-2 for a sample calculation of a switch configuration.

Switch Ground Connection

This section describes how to connect a system (earth) ground to the Catalyst 6000 family switches. Two grounding holes are provided on the chassis frame (see Figure 3-1 for the grounding hole location; the location is the same on all Catalyst 6000 family switches).

Note The earth ground should be used on both AC- and DC-powered systems.

Required Tools and Materials

To connect the switch to an earth ground, you need the following tools and materials:

Note Materials are not provided; contact any commercial cable vendor for the required parts.

• Grounding lug---The grounding lug must have two M4 screw holes.

• Two M4 (metric) hex-head screws with locking washers.

• One grounding wire (6 AWG recommended)---The length of the grounding wires depends on the proximity of the switch to proper grounding facilities.

• Number 2 Phillips head screwdriver.

• Crimping/wire-stripping tool.

Connecting System Ground

We strongly recommend that you complete this procedure before connecting system power or turning on the Catalyst 6000 family switch.

To attach the grounding lug and cable to the grounding pad, perform these steps:

Step 2 Insert the stripped end of the grounding wire into the open end of the grounding lug.

Step 3 Use a crimping tool to secure the grounding wire in place in the grounding lug.

Step 4 Locate the grounding pad on the switch (see Figure 3-1).

Power Connection Guidelines for AC-Powered Systems

This section provides the guidelines for connecting the Catalyst 6000 family switch AC power supplies to the site power source. There are three types of AC-input power supplies available:

• 1000W---Figure 3-2 shows the different styles of 1000W AC-input power plugs that are available for North America or various international locales. Table 3-3 lists the AC-input power cord options and Cisco product numbers.

• 1300W---Figure 3-2 shows the different styles of 1300W AC-input power plugs that are available for North America or various international locales. Table 3-3 lists the AC-input power cord options and Cisco product numbers.

---

Note For North America, the plug types are different for the 1000W and 1300W power supplies; for other countries, the plugs shown in Figure 3-2 are the same for both 1000W and 1300W power supplies.

---

• 2500W---Figure 3-3 shows the different styles of 2500W AC-input power plugs that are available for North American or various international locales. Table 3-3 lists the AC-input power cord options and Cisco product numbers.

Make sure you have the correct power cord for your site.
