Chapter 7. Testing
Problems with the SurePOS 700 can be caused by software errors or hardware
failures. This chapter contains problem-analysis tables to help determine the cause
of a problem and how to solve it.
When you power on the SurePOS 700, the system runs a power on self test
(POST). A successful POST is indicated by:
v A single beep
v The power and UPS status indicators are both on and not blinking.
If the POST is unsuccessful, see “Problem isolation” on page 118.
Preliminary checklist
If you have a problem with the SurePOS 700, first use the following checklist:
1. Make sure that all I/O devices are connected correctly.
2. Make sure that AC power is connected.
3. Make sure that the contrast and the brightness controls on the display are
adjusted correctly.
4. Make sure that all installed hardware (such as a memory module, feature card,
printer, or mouse) and cables are connected correctly and securely.
5. Power ON and listen for one or two beeps at the completion of the POST.
6. If POST does not complete, power OFF the SurePOS 700 and remove any
optional adapters and all I/O devices except a single keyboard and display.
7. If POST still fails to complete, see “Problem isolation” on page 118.
