OCPRF100 MP Server System Technical Product Specification

Revision 1.0

•Secure mode, video blank, and floppy write protect

•Front panel NMI monitoring

•Software front panel NMI generation

3.4.3Hot-swap Controller

The hot-swap controller (HSC) on the LVDS SCSI hot-swap backplane is connected to other system boards via the IPMB. The HSC provides server management information through both the IPMB and the SCSI Accessed Fault-Tolerant Enclosures (SAF-TE). SAF-TE is an industry standard for communicating drive and slot status.

The HSC:

•implements the SAF-TE command set accessed through SCSI;

•provides an IPMB path for drive presence, drive fault status, backplane temperature, and fan failure;

•controls the fault lights and drive power on the OCPRF100 MP server system chassis hot-swap backplane;

•monitors the power distribution backplane for power supply status; and

•controls drive power on and off, facilitating hot-swapping of drives.
