Installing the Cisco Wide Area Application Engine

Place the device in the desired location. You can mount it in a rack for your convenience, or place it on a solid, stable surface. If you do not plan to install the unit in an equipment rack, proceed to the "Installing the Chassis on a Tabletop" section.

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.

Warning


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


Installing the Chassis in a Two-Post Rack

The chassis mounts to two rack posts with brackets that attach to the sides of the chassis. These brackets are for a 19-inch (48.26-cm) equipment rack and require four screws in each bracket. (See Figure 3-1.)

Figure 3-1 Rack-Mount Brackets

To install the chassis in a two-post rack, follow these steps:


Step 1 Attach a bracket to one side of the chassis, aligning the front flange of the bracket with the hash mark on the side of the chassis. (See Figure 3-2.)

Figure 3-2 Installing the Chassis in the Rack

Step 2 Attach a second bracket to the opposite side of the chassis in the same manner.

Step 3 After you secure the brackets to the chassis, rack-mount the chassis by threading at least two screws through the bracket flanges on each side of the chassis into the corresponding holes in each side of the rack. You need two people to install the chassis in the rack—one person to hold the chassis and one person to secure it to the rack.

The inlet and exhaust ports for cooling air are located in the front and rear of the chassis, respectively; therefore, multiple chassis can be stacked with little or no vertical clearance.


Installing the Chassis in a Four-Post Rack

The four-post rack-mounting system does not require any tools for installation, unless you are shipping a device mounted in a rack. When you are shipping a device in a rack, you need a Phillips screwdriver. Figure 3-3 shows the items that you need to install the chassis in a four-post rack. If any items are missing or damaged, contact your place of purchase.

These slide rails come with spring-loaded locking pins at both ends of each rail. To attach the slide rails to an equipment rack, you need to pull back the pin carriage, align the pins with holes in the equipment rack-mounting flange, and release the pin carriage to lock the pins into the rack posts. A rail-adjustment bracket allows you to adjust the length of the slide rails to fit the rack. (See Figure 3-4.)

The chassis rests on the lower ledges provided by the two rails and slides in and out of the rack along the rail ledges.

To install the chassis in a four-post rack, follow these steps:


Step 1 To begin, open the pin carriages at the front and rear of the left slide rail:

On the front of the rail, press on tabs labeled (2) and (3) in Figure 3-4, and slide the pin carriage toward the rear of the rail, releasing the latch tab (2) as it catches in place.

On the rear of the rail, press on the two rear tabs, and slide the pin carriage toward the front of the rail, releasing the latch tab as it catches in place. To prevent the rail-adjustment bracket (labeled 1 in Figure 3-4) from moving during this step, hold it in place with your thumb.


Note Slide rails are marked (RIGHT/FRONT and LEFT/FRONT) for proper placement.

Step 2 To adjust the length of the slide rail, lift the release tab (labeled 1 in Figure 3-5) and fully extend the rail-adjustment bracket from the rear of the slide rail until it snaps into place.

Step 3 To secure the slide rail to the equipment rack, align the pins on the rear of the slide rail with the holes on the rear mounting flange. Press the latch tab (labeled 2 in Figure 3-5) to release the pin carriage.


Note Ensure that the pins are fully extended through the mounting flange and slide rail pin bracket. (See Figure 3-5.)

Step 5 Repeat these steps for the right slide rail. Make sure that you attach the second slide rail at the same rack height as the first one so that the chassis will be level in the rack.

Step 6 To install the chassis in the rack, align the chassis on the slide rails and push the chassis fully into the rack. Secure the chassis to the front mounting flanges with the captive thumbscrews (labeled 1 in Figure 3-7).


Note You must leave the shipping brackets (labeled 2 in Figure 3-7) attached to the slide rails unless the shipping brackets impede the chassis from sliding fully into the rack. If you need to remove the shipping brackets, continue with Step 7.

Step 7 To remove the shipping bracket, press on the release tab (labeled 1 in Figure 3-8) as indicated on the shipping bracket, and remove the shipping bracket from the slide rail. Repeat this step for the other shipping bracket. Store the shipping brackets for future use.


Note You must reinstall the shipping brackets on the slide rails before you transport the rack with the chassis installed. To reinstall the shipping brackets, reverse this step.

Step 8 Attach the power cords and the Ethernet cables to the rear of the device. Route the cables to the left corner of the chassis (as viewed from the rear) and use the cable straps to secure the cables to the slide rails. (See Figure 3-9.)

Figure 3-9 Securing the Cables


Note Leave enough slack in the cables to allow for sliding the device in or out of the rack.


Step 9 To transport the rack to another location with the chassis installed, you must secure the chassis to the rack.

a. Remove one mounting screw and loosen the other mounting screws as indicated in Figure 3-10.

Figure 3-10 Securing the Chassis for Transporting in the Rack

b. If necessary, disconnect the cables from the rear of the chassis, then slide the chassis out of the rack six inches (150 mm).

c. Fully extend the rail, and reinsert the M6 screws in each slide rail. To secure the rail, tighten all screws. The rails should be fully extended to the rear of the rack, and the shipping brackets should be installed.

d. Secure the chassis to the rack with the M6 screws.

To remove the chassis from the rack, reverse these instructions. Store these installation instructions with your product documentation for future use.



Note The four-post rack-mounting system is designed for racks that do not have pre-threaded holes. If you are using an equipment rack with pre-threaded holes, the pins will not protrude through the rack. Instead, secure the slide rails to the rack by attaching screws through the slide rail pin brackets at both ends of each rail. (See Figure 3-11.)

Installing the Chassis on a Tabletop

When you install a chassis on a workbench or tabletop, ensure that the surface is clean and in a safe location and that you have considered the following:

The chassis 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 device 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 chassis for accessing network cables or equipment.

The device must receive adequate ventilation (it cannot be installed in an enclosed cabinet where ventilation is inadequate).

To install the chassis 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 device 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.


Connecting Cables

To connect network and console cables to the device, follow these steps:


Step 1 For network connections, insert a Category 5 UTP cable into the Ethernet 1 or Ethernet 2 receptacle on the device back panel. (See Figure 3-12.)

Step 2 Connect the other end of the network cable to a hub or switch in your network.


Note We strongly recommend that you do not use half-duplex connections on the WAE or on routers, switches, or other devices.


Step 3 For console connections, plug the serial cable into the serial port on the device back panel.

Step 4 Connect the other end of the console cable to a console or a communications server.

Note The system software does not support the use of a keyboard or mouse (PS/2 or USB). However, a keyboard and mouse are supported by the BIOS for power-on self-test (POST) and troubleshooting purposes.


Connecting Power and Booting the System

To connect power to the device, follow these steps:


Step 1 Review the information in the "Safety Warnings" section.

Step 2 Plug the AC power cord into the power cord receptacle at the rear of the device. (See Figure 3-12.)

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 device.

The system should begin booting. Once the operating system boots, you are ready to initialize the basic software configuration. (See the "Related Documentation" section for a list of software configuration documents.)


Note While the device is powering up, the power LED on the front of the chassis is green.



Checking the LEDs

When the device is up and running, observe the front panel LEDs. To verify that your system is operating properly, see the "LED Indicators" section.

Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units. Statement 246



Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040


To remove a device from your network, power it down, disconnect the power cords and network cables, and physically remove the chassis from the rack.

The device is in constant communication with the router on your network. When the router notices that the device is no longer responding to it, the router stops sending requests to the device. This is transparent to users. If other devices are attached to the router, the router continues sending requests to the other devices.

When you remove a device, the pages that were cached on that device are no longer available to the router or other devices, and you might see an increase in outgoing web traffic that might have otherwise been fulfilled by the device that you are removing. However, after a time, the router and other devices redistribute the load of web traffic.

If you remove the last device from your network, you can also disable device support on the router. However, this is not necessary; having device support enabled when there are no devices attached has no effect on the router's performance.

To replace a device, remove it from the network, and then install a new device. Configure it using the same configuration parameters (IP address, and so forth) that you used for the removed device.
