Hardware Maintenance Manual: Netfinity 4500R Type 8656
The following illustration shows the LEDs on the diagnostics panel on the system
board. See "Light path diagnostics table" for information on identifying problems
using these LEDs.
The System Error LED on the operator information panel is lit when certain system
errors occur. If the System Error LED on your server is lit, use the following table to
help determine the cause of the error and the action you should take. See table in
"Information panel system error LED" on page 114.
When you turn on the server, it performs a series of tests to check the operation of
server components and some of the options installed in the server. This series of tests
is called the power-on self-test or POST.
If POST finishes without detecting any problems, a single beep sounds, the first screen
of your operating system or application program appears, and the System POST
Complete (OK) light is illuminated on the operator information panel.
If POST detects a problem, more than one beep sounds and an error message appears
on your screen. See "Beep symptoms" on page 111 and "POST error messages" on
page 13 for more information.
Notes:
1.
If you have a power-on password or administrator password set, you must type
the password and press Enter, when prompted, before POST will continue.
