Cisco Wide Area Application Engine 7326 Hardware Installation Guide
OL-6831-02
Note Cisco ACNS software does not support the use of a keyboard or mouse
(Personal System/2 [PS/2] or Universal Serial Bus [USB]) for Linux and ACNS
software troubleshooting. However, the keyboard and mouse are supported by the
BIOS for power-on self-test (POST) and diagnostic programs that are located in
the device ROM.
When console redirection is enabled, all the tests available from a keyboard are
accessible through the console connection as well. (Mouse support, however, is
not available through the console connection.)
You can run all the diagnostics and tests that are supported by the BIOS, with a
few exceptions. Tests for a disk drive, for example, are invalid because the device
does not include a disk drive in the hardware configuration.
Tests for peripheral devices (such as mouse, keyboard, and monitor) and ports
(such as the USB port) that are not supported by ACNS software are also invalid.
Caution Customer-replaceable components include the Fibre Channel adapter and hard
disk drives. All other components that are not orderable as spare hardware options
can only be replaced by a qualified service technician. Once you have identified
a faulty component, contact Cisco Technical Support. (See the “Obtaining
Documentation” section on page xvii.)
Note Read the “Working Inside the WAE with the Power On” section on page 2-7
before opening the chassis cover.
