SCSI Enclosure Services (SES)
The A33606-PCI-60-6A comes pre-configured with the following enclosure services.
Temperature sensors that monitor chip temperature and board temperature.
Voltage monitors for on-board voltages.
Fan monitoring and control.
Slot mapping for 24 drives as numbered above.
Enclosure naming.
Access to SCSI enclosure services is provided by the HBA or RAID card. Most RAID card manufacturers
provide software that monitors the SCSI enclosure services and can be configured to generate messages
(via a popup or email) if one of the elements exceeds a limit.
A SCSI enclosure element is a portion of an enclosure that is controlled, interrogated, or described
through SCSI enclosure services. The A33606-PCI-60-6A conforms to the T10 SCSI Enclosure Services
(SES-2) specification.
Temperature Elements
SES will monitor and report on 3 temperature sensors.
Expander Temperature
PCB Temperature
External temperature
Thresholds for high and low temperature limits can be set through SES. If a temperature threshold limit is
exceeded, the expander will report a failure through SES and illuminate the ERROR LED on the front
panel. The default thresholds are listed below.

Voltage Sensor Elements
The expander monitors four on-board voltages:
12V power input
3.3V expander voltage
1.8V expander voltage
1.0V expander voltage
Thresholds for high and low voltage limits can be set through SES. If a voltage threshold limit is
exceeded, the expander will report a failure through SES and illuminate the ERROR LED on the front
panel. The default thresholds are listed below.
