Table 8. 6Gb/s SAS EBOD I/O Module LED Descriptions
LED
Description
I/O Module OK Constant green if the I/O module is operating correctly. Flashing green
indicates an I/O module VPD error.
I/O Module Fault Constant amber if the I/O module is faulty. For replacement procedure
see “Replacing an SBB I/O module” on page 45.
External Host Port Activity Constant green indicates that there is a host port connection but no
activity. Flashing green indicates that there is a host port connection,
and data is being transferred.
Thermal sensors
Thermal sensors throughout the enclosure and its components monitor the thermal health of the storage
system. Exceeding the limits of critical values will cause the Over-temperature alarm to occur.
Troubleshooting
The following sections describe problems that can occur with your storage systems and some possible
solutions. The module fault LED on the ops panel displays a solid amber color to indicate a fault. All
alarms will also be reported by SES. See Elastic Storage Server Spectrum Scale RAID Administration Guide
and the Maintenance Procedures section in Elastic Storage Server Problem Determination Guide.
