Troubleshooting the MDS600 storage enclosure
For troubleshooting purposes, be sure to check the following:
• MDS600 enclosure LEDs—show enclosure health status.
• Fan, power supply, and I/O modules—show module health status.
• 7-segment display panel—shows numeric codes that indicate a variety of self-discovered faults
and warnings. By selecting the UID button on each drawer, the 7-segment display panel shows
numeric codes that indicate why the GSI LED is enabled.
• Cabling—make sure the cabling scheme is supported for use in this solution.
NOTE: When the front-panel GSI LED or the rear-panel I/O module LED is Amber, in addition
to indicating a potential issue with a physical component, it may indicate that firmware needs to
be updated or re-installed on the I/O modules.
For more information about LED displays or 7-segment codes, see the HP 600 Modular Disk System
Maintenance and Service Guide or HP 600 Modular Disk System User Guide.
