Cisco Systems 274 Manuale Utente

This section lists the error codes, error messages, and the various indicator light 
and beep sequences that you may encounter during the Power-On Self-Test 
(POST) or appliance restart, the probable source of the problem, and steps you can 
take to resolve the error condition.

The POST Message Disabled mode suppresses most system messages during 
POST, such as the memory count and non-error text messages. If a POST error 
occurs, the screen will display the error message. To switch to the POST Messages 
Enabled mode during POST, press any key (except F10 or F12). The default mode 
is POST Message Disabled.

This section contains the following topics:

When you power up the device, it performs a series of tests to check the operation 
of device components. This series of tests is called the power-on self-test, or 
POST.

If POST finishes without detecting any problems, no beeps sound, and the first 
screen of your operating system or application program appears.

If POST detects a problem, more than one beep sounds, and an error message 
appears on your screen. See the 

 for more information.

If you have a power-up password or administrator password set, you must enter 
the password and press Enter when prompted, before POST will continue.
