Error Messages
There are three kinds of error messages; two types appear during the POST process and the third is not a
visual message, but an audible message (beep codes). Any one of these three types of error messages
could point to a problem which might prevent the Netserver from completing the boot process. These are:
•
Error messages (reverse video) – These text messages display in black text on white
background and can provide more information on screen.
Press the [Enter] key to see a definition of the message and what action to take to remedy the
problem. A sample of these messages appear in Table 4-1.
•
Power On Self Test (POST) codes - These display in normal video (white text on black
background) and may be a text message or an alpha numeric code. If an error with a text
message occurs during the POST, details of the error are displayed. Follow the instructions on
the screen. If an alpha-numeric code appears, refer to Table 4-2 later in this chapter
.
•
Beep Codes – These are series of audible beeps, which occur during the boot process before
the video display can initialize allowing the visual messages of the POST routines to appear.
Refer to the Table 4-3 later in this chapter.
