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:

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.

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.

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.
