Texas Memory Systems RAM-SAN 520 - Manual (Page 24)

power glitches or a serious hardware failure. If a configuration LED stays lit after power-up, do the
following:
• Verify that the oscillator is firmly inserted into its slot. The oscillator is located in the center of the
system motherboard, between the connectors for memory slot 5. The writing on the oscillator should be
oriented in the same direction as the text next to it on the motherboard that reads “50MHz” and “3.3V”.
• Check that the system configuration board is properly seated in its connector at the top of the interface
motherboard. If it has come loose or doesn’t look fully seated, push the board gently back into place.
Make sure it is aligned in its slide rails before pushing the connectors together.
• Make sure that all RAM-SAN internal fans are operational and have unblocked airflow. The RAM-SAN
power supply will go into thermal shutdown if it is not properly cooled. This will cause the power LEDs
to blink as they turns themselves on and off depending upon the internal temperature. If one of the
RAM-SAN power modules turns off, parts of the system will be unable to reconfigure themselves and
will leave the configuration LED on.
• If you suspect that the RAM-SAN has experienced a power surge or glitch, turn off the RAM-SAN, wait
for the internal fans to stop and then turn the system back on.
6.8 ECC Errors Detected
The RAM-SAN hardware has a mechanism for detecting system data errors using an error correction code
(ECC). ECC errors are caused by bits being read from system memory incorrectly and are reported to the
management port. If an ECC error is detected the management port reports:
** ECC error detected
Please follow the steps in section 6.4 to pinpoint the erroneous memory board and/or chip and call Texas
Memory Systems customer support. You will need to be at the RAM-SAN monitor while talking to a
customer support technician, with an error logged on the management port (resetting or turning off the
RAM-SAN will cause the management port to lose the ECC error log).
