Introducing the Cisco Wide Area Application Engine


This chapter provides a basic functional overview of the Cisco Wide Area Application Engine (WAE) 7371, 7341, and 674 appliances and describes the hardware, major components, and front and back panel indicators and controls.

The WAE-7371, WAE-7341, and WAE-674 appliances share an identical platform, but differ in the number of CPUs, installed memory, number of installed hard disks, and number of installed power supplies.

This chapter contains the following sections:

Note Throughout this book, references to the WAE appliance include the WAE-7371, WAE-7341, and WAE-674 appliances, unless specifically noted otherwise.


Supported Products

The Wide Area Application Engine (WAE) 7371, 7341, and 674 appliances support the following products and software versions:

The WAE-7371 appliance supports Cisco Wide Area Application Services (WAAS) software version 4.0.13.23 or later.

The WAE-7341 appliance supports the WAAS software version 4.0.13.23 or later and the Cisco Application and Content Networking System (ACNS) software version 5.5.9 or later.

The WAE-674 appliance supports WAAS software version 4.0.15.6 or later and ACNS software version 5.5.9 or later.

Hardware Features

This section illustrates and describes the front and back panel controls, ports, and LED indicators on the WAE-7371, WAE-7341, and WAE-674. It contains the following topics:

Front Panel Controls and LEDs

Figure 1-1 shows the front panel controls and LEDs.

Figure 1-1 Front Panel

The power control button powers up and powers down the system. A power control button shield prevents the system from being powered down accidentally.

On the operator information panel, slide the release latch to the left to access the Light Path Diagnostics panel, which is behind the operator information panel. For more information on Light Path Diagnostics, see the "Identifying Problems Using Trouble Indicators and Status LEDs" section on page 6-15.


Note The system software does not support the use of a keyboard or mouse (Personal System 2 [PS/2] or Universal Serial Bus [USB]). The BIOS does support a keyboard and a mouse for power-on self-test (POST) and the configuration/setup utility.
To troubleshoot the BIOS boot process, you can connect a keyboard to any USB port and connect a monitor to the video connector. Video output is for troubleshooting only during the BIOS boot process. The video output stops displaying when the serial port becomes active. To monitor the boot process in normal operation, use the serial console port.


Table 1-1 describes the front panel LEDs and their functions.

Note You can connect a keyboard to any USB port and connect a monitor to the video connector to troubleshoot the BIOS boot process. However, video output is for troubleshooting only during the BIOS boot process. The video output stops displaying when the serial port becomes active. To monitor the boot process in normal operation, use the serial console port.
The Serial Attached SCSI (SAS) connector is not supported.
The systems-management Ethernet connector is not supported.

Ethernet link

Green

On

Active link connection on the 10BASE-T, 100BASE-TX, or 1000BASE-TX interface for the Ethernet port.

Ethernet activity

Green

On

System is transmitting to or receiving signals from the Ethernet LAN that is connected to the Ethernet port.

Power-on

Green

On
Flashing

Off

Appliance is powered on.
Appliance is powered off and still connected to an AC power source.
AC power is not present. Power supply or LED has failed.

System-locator

Blue

On

Visually locates the device among other devices.

System-error

Amber

On

System error has occurred. An LED on the Light Path Diagnostics panel is also lit to help isolate the error.

AC Power

Green

On

Sufficient AC power is coming into the power supply through the power cord. During typical operation, both the AC and the DC power LEDs are on.

DC Power

Green

On

Power supply is supplying adequate DC power to the system. During typical operation, both the AC and the DC power LEDs are on.


Location of Ports and Connectors

The WAE appliance supports two Ethernet connectors and one serial I/O connector on the front and back of the device.

Ethernet Port Connectors

Serial Port Connector

Figure 1-2 shows the back panel ports and connectors.


Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021


Ethernet Port Connectors

Connect a Category 3, 4, or 5 unshielded twisted-pair cable to an Ethernet connector. 100BASE-TX and 1000BASE-T Fast Ethernet standards require Category 5 or higher cabling.

The WAE has three Ethernet connectors. Two of the Ethernet connectors are attached to the Ethernet controllers and the third connector is the systems-management Ethernet connector, which is not supported by the WAAS software.

The Ethernet controllers are integrated on the system board. They provide an interface for connecting to a 10-Mbps, 100-Mbps, or 1-Gbps network and provide full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the network. If the Ethernet ports in the server support auto negotiation, the controllers detect the data-transfer rate (10BASE-T, 100BASE-TX, or 1000BASE-T) and duplex mode (full duplex or half duplex) of the network and automatically operate at that rate and mode. You do not have to set any jumpers or configure the controllers.

If a problem occurs with the primary Ethernet connection, all Ethernet traffic associated with this primary connection is automatically switched to the redundant Ethernet connection. If the applicable device drivers are installed, switching occurs without data loss and without user intervention.

Serial Port Connector

The WAE has one serial port connector. Use the serial port connector to connect a serial device.
