The PDB provides power from the power supply modules to the JBOD components, and provides thermal

monitoring and fan control, and includes the following features:

The PDB connects to the power supply canister through two CRPS card edge connectors.



Optional 2x12-pin SSI and 1x5-pin SSI power control headers (for potential future use)



Power for up to two internal 36-port SAS expander cards (RES3FV288) with additional connectors for



future use

Two 2x4-pin 12V power headers and an additional two 2x4-pin 12V power headers for future use,



each cable is used to connect power to a single 12x 3.5" HSBP or up to three 8x 2.5" HSBPs.

Support for hot-swap redundant fan speed control solutions up to four system fans and identification



of fan failures at front panel fault LED indicator with communication over SES2 interface to host PC

SMB interface for communicating enclosure status through the expander board to the host system



external host controller via SES interface. Monitoring capabilities include:

Fan tachs.

12V voltage out from PSU.

Temperature sensor on front panel.

Ambient overtemp protection: Reported to host system and fan boost only. No shutdown.

Degraded (PSU, FAN) state reportable to host system and on JBOD status LED.

A 3-pin jumper (J2C1) allows setting the Auto Power Enable/Disable setting. The auto power-on jumper

setting determines whether the JBOD power-on status will resume automatically if system power is removed

and then reapplied. When Auto-Power-On is enabled, the JBOD will power on automatically with application

of AC power. When Auto-Power-On is disabled, the JBOD is powered on using the Front Panel push-button

switch. The jumper options are described in the table below.
