Chapter 1: Introduction Number Generator (RNG) for stronger encryption, digital signing and secu- rity protocols. The FWH stores the system BIOS and video BIOS to eliminate a redundant nonvolatile memory component. Processors The 370SSR+/370SSE+ supports single 370-pin Pentium III FCPGA 600 MHz- 1 GHz and Celeron FCPGA/PPGA 300-700 MHz processors with Front Side Bus Speeds of 133/100/66 MHz. Please refer to the support section of our web site for a complete listing of supported processors (http:// www.supermicro.com/TechSupport.htm). Memory The 370SSR+/370SSE+ has three (3) 168-pin DIMM 25 0 sockets that can support up to 512 MB of unbuffered PC133 and PC100 SDRAM.
Module sizes of 128MB, 256MB, and 512MB may be used to populate the DIMM slots. The DIMM slots are situated at a 25 degree angle to create a low profile and to promote efficient airflow through the chassis. Onboard SCSI (5010H only) Onboard SCSI is provided with an Adaptec AIC-7899 SCSI controller chip, which supports dual channel, Ultra160 SCSI at a burst throughput rate of 160 MB/sec for each channel. The 370SSR+ provides two SCSI ports: one internal 68-pin LVD Ultra160 connector (on channels A) and one external/ internal (shared) 68-pin Ultra160 SCSI connector (channel B). PCI Expansion Slots The 370SSR+/370SSE+ has one 32-bit 33 MHz PCI slot available.
One riser card is included with the system for use with 32-bit PCI cards. Network Interface Controllers (NIC) The 370SSR+/370SSE+ supports two Network Interface controllers (NIC) based on Intel's 82559 and 82562 chips. (For the 5010H server that is based on the 370SSR+ Version 1.2 mainboard, two 82559 Ethernet chips are included in the system.) 1-5
