The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes how to install a WAVE-574 in an equipment rack. This chapter contains the following sections:
•Rack-Mounting Parts, Tools, and Considerations
•Rack Mounting and Cabling the WAVE-574
•Connecting Power and Booting the System
•Removing or Replacing a WAVE Appliance
Before you begin the installation, read Chapter 2, "Preparing to Install the WAVE-574" and the Regulatory Compliance and Safety Information for the Cisco Content Networking Product Series document.
Warning Read the installation instructions before connecting the system to the power source. Statement 1004.
A rack mounting hardware kit is included in your shipping container. To mount the WAVE-574 in the rack, you need a T-10/T-15 Torx screwdriver.
To allow for servicing and adequate airflow, observe the following space and airflow requirements when deciding where to install a rack:
•Leave a minimum clearance of 63.5 cm (25 in) in front of the rack.
•Leave a minimum clearance of 76.2 cm (30 in) behind the rack.
•Leave a minimum clearance of 121.9 cm (48 in) from the back of the rack to the back of another rack or row of racks.
The WAVE-574 draws in cool air through the front door and expels warm air through the rear door. Therefore, the front and rear rack doors must be adequately ventilated to allow ambient room air to enter the cabinet, and the rear door must be adequately ventilated to allow the warm air to escape from the cabinet.
When vertical space in the rack is not filled by a WAVE appliance or rack component, the gaps between the components cause changes in airflow through the rack and across the WAVE appliances. Cover all gaps with filler panels to maintain proper airflow.
•Observe the following additional requirements to ensure adequate airflow and to prevent damage to the equipment:
–Front and rear doors—If the 42U rack includes closing front and rear doors, you must allow 5,350 sq cm (830 sq in) of holes evenly distributed from top to bottom to permit adequate airflow (equivalent to the required 64 percent open area for ventilation).
–Side—The clearance between the installed rack component and the side panels of the rack must be a minimum of 7 cm (2.75 in).
To install the WAVE appliance into a rack with square, round, or threaded holes, refer to the instructions that ship with the rack hardware kit.
Use the following information (see Figure 3-1) when connecting peripheral cables and power cords to the WAVE appliance.
Warning To reduce the risk of electric shock, fire, or damage to the equipment, do not plug telephone or telecommunications connectors into RJ-45 connectors.

To connect power to your system, follow these steps:
Step 1 Review the information in the "Safety Guidelines" section on page 2-3.
Step 2 Plug a power cord into the power cord receptacle on the back of the WAVE appliance.
Step 3 Connect the other end of the power cord to a power source at your installation site.
Step 4 Power up all externally connected devices.
Step 5 Press the power control button on the front of the WAVE appliance.
The system should begin booting. Once the operating system boots, you are ready to initialize the basic software configuration. (See the software configuration guide for details.)
Note While the WAVE appliance is powering up, the green power-on LED on the front of the appliance is on.
When the WAVE-574 is up and running, observe the front panel LEDs (see Figure 1-1 and Table 1-1) to verify that your system is operating properly.
To troubleshoot using the LEDs, see Chapter 6, "Troubleshooting the System Hardware."
To remove a WAVE appliance from your network, power it down, disconnect the power cords and network cables, and physically remove the chassis from the rack.
The WAVE appliance is in constant communication with the router on your network. When the router notices that the WAVE appliance is no longer responding to it, the router stops sending requests to the WAVE appliance. This action is transparent to users. If other WAVE appliances are attached to the router, the router continues sending requests to the other WAVE appliances.
When you remove a WAVE appliance, the pages that were cached on that appliance are no longer available to the router or other WAVE appliances. You might see an increase in outgoing web traffic that might have otherwise been fulfilled by the WAVE appliance that you are removing. However, after a time, the router and other WAVE appliances redistribute the load of web traffic.
If you remove the last WAVE appliance from your network, you can also disable WAVE support on the router. However, this action is not necessary because leaving WAVE support enabled when there are no WAVE appliances attached has no effect on the router's performance.
To replace a WAVE appliance, remove it from the network, and then install a new WAVE appliance and configure it using the same configuration parameters (IP address and so forth) that you used for the removed WAVE appliance.
