Verify 35900 is Ready for Operation
At power up, the 35900 automatically executes internal self-tests to determine
the amount of memory installed and to verify that the main processor, system
memory, the MIO communication interface, and other internal circuits are
operating properly. These tests take about 30 seconds for 1-Mbyte system. The
FAULT light will blink ON/OFF during this time.
When the 35900 has completed the internal self-tests, verify that:
• The FAULT lamp is OFF.
• The POWER indicator is ON.
• No other indicators are blinking.
You can use the test chromatogram stored in the 35900 ROM in conjunction
with the Host computer software to check the operation of the entire system.
The test chromatogram is turned on via configuration switches 3 through 6 on
the 35900's back panel.
In Case of Difficulty
If the 35900 does not power up correctly, turn power off and check the
following:
• Rear panel configuration switches 3 through 6 are DOWN (for normal
operation).
• MIO card is correctly configured for host computer communications.
• MIO card is connected to host computer or network.
• Analog signal cables are connected.
• Remote control cables are connected (if needed).
• Digital I/O cables are connected (if needed).
• Power cord is connected.
If the problem persists after cycling the power, note the LED pattern on the
front panel display. Check Table 11 for possible causes for failure. If the fault
condition persists, contact Agilent for service.
