•Installing the WAVE Appliance on a Wall
•Installing the WAVE Appliance in an Equipment Rack
•Connecting Power and Booting the System
•Checking the LEDs
•Removing or Replacing a WAVE Appliance
Before you begin the installation, read Chapter 2, "Preparing to Install the Wide Area Virtualization Engine" and the Regulatory Compliance and Safety Information for the Cisco Wide Area Virtualization Engines document.
Warning Read the installation instructions before connecting the system to the power source. Statement 1004
Installing the WAVE Appliance on a Tabletop
When you install a WAVE appliance on a workbench or tabletop, ensure that the surface is clean and in a safe location and that you have considered the following points:
•The WAVE appliance should be installed off the floor. (Dust that accumulates on the floor is drawn into the interior of the chassis by the cooling fans. Excessive dust inside the WAVE appliance can cause overtemperature conditions and component failures.)
•There must be approximately 19 inches (48.26 cm) of clearance at the front and rear of the WAVE appliance for accessing network cables or equipment.
•The front should be completely clear. Leave 0.4 inches (10-mm) of clearance on the sides and top of the appliance and at least 2.0 inches (50 mm) of clearance in the rear. The rear vents should be completely clear.
To install the WAVE appliance on a workbench or tabletop, follow these steps:
Step 1 Remove any debris and dust from the tabletop or workbench, as well as from the surrounding area. Also make sure that your path between the WAVE appliance and its new location is unobstructed.
Step 2 Place the chassis on the tabletop or workbench.
Step 3 Ensure that no exhaust air from other equipment will be drawn into the chassis. Also make sure that there is adequate clearance at the front and rear of the chassis.
Installing the WAVE Appliance on a Wall
You can mount the WAVE appliance on a wall or underneath a desk or workbench using the optional mounting sleeve. See Figure 3-1. Make sure that you consider the location requirements as described in the "Installing the WAVE Appliance on a Tabletop" section.
Figure 3-1 WAVE-274 and WAVE-474 Appliance Mounting Sleeve
To mount your WAVE appliance using the mounting sleeve, follow these steps.
Step 1 Power down the appliance before beginning the installation.
Step 2 Orient the mounting sleeve as desired and attach it to the mounting surface using the fasteners provided or other appropriate fasteners. See Figure 3-2.
Mounting surfaces vary widely. We recommend that you use the appropriate screws or other mounting solution for your type of surface. Be sure your mounting solution is properly installed to support the weight.

Step 3 Slide the WAVE appliance into the mounting sleeve as shown. See Figure 3-3.

Installing the WAVE Appliance in an Equipment Rack
Use the optional rackmount shelf to install your WAVE-274 or WAVE-474 in an equipment rack. Make sure that you follow the guidelines described in the following topics:
Before installing your WAVE appliance in a rack, review the following guidelines:
•Ensure that the room air temperature is below 95 ×F (35 ×C).
•Do not block any air vents; usually 6 inches (15 cm) of space provides proper airflow.
•Plan the device installation starting from the bottom of the rack.
•Install the heaviest device in the bottom of the rack.
•Do not extend more than one device out of the rack at the same time.
•Remove the rack doors and side panels to provide easier access during installation.
•Connect the WAVE appliance to a properly grounded outlet.
•Do not overload the power outlet when installing multiple devices in the rack.
Use safe practices when lifting.
Do not place any object weighing more than 110 lb (50 kg) on top of rack-mounted devices.
Install the appliance only in a rack cabinet with perforated doors.
Install your WAVE appliance in a rack that meets the following requirements:
•Minimum depth of 2.76 inches (70 mm) between the front mounting flange and inside of the front door.
•Minimum depth of 6.18 inches (157 mm) between the rear mounting flange and inside of the rear door.
•Minimum depth of 28.27 inches (718 mm) and maximum depth of 30 inches (762 mm) between the front and rear mounting flanges to support the use of the cable-management arm.
Racks are marked in vertical increments of 1.75 inches (4.44 cm). Each increment is referred to as a rack unit (RU). A 1-RU device is 1.75 inches (4.44 cm) tall.
To install the WAVE appliance in an equipment rack, follow these steps:
Step 1 Power down the appliance before beginning the installation.
Step 2 Attach shelf to rack rails with mounting hardware as shown in Figure 3-4.
Figure 3-4 Attaching the Rack Shelf
Note The shelf may be mounted upside down and will not loose any of its weight capacity.
Step 3 Place the chassis on the rack shelf.
To connect cables to your WAVE appliance, follow these steps:
Step 1 Power down the appliance before connecting cables to or disconnecting any cables from the appliance.
Step 2 See the documentation that comes with your optional equipment for additional cabling instructions. It might be easier for you to route the cables before you install specific optional equipment.
Step 3 See the cable identifiers that are printed on the cables that come with the WAVE appliance and options. Use these identifiers to connect the cables to the correct connectors.
Figure 1-2 shows the locations of the input and output connectors on your appliance.
Connecting Power and Booting the System
To connect power to your system, follow these steps:
Step 1 Review the information in the "Safety Guidelines" section on page 2-4.
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 WAVE appliance is on.
Checking the LEDs
When the WAVE appliance 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 5, "Troubleshooting the System Hardware."
Removing or Replacing a WAVE Appliance
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 device 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 appliance support on the router. However, this action is not necessary because leaving WAVE appliance 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.
