Technical Product Specification

Intel® Server Boards S4600LH2/T2 TPS
Revision 2.0
47
On the Intel
®
Server Boards S4600LH2 and S4600LT2, the chipset provides support for the following on-board
functions:
• Low Pin Count (LPC) interface
• Universal Serial Bus (USB) Controller
• Serial Attached SCSI (SAS) / Serial ATA (SATA) Support
• Manageability Features
3.3.1 Low Pin Count (LPC) Interface
The chipset implements an LPC Interface as described in the LPC 1.1Specification and provides support for up
to two Master/DMI devices. On the server board, the LPC interface is utilized as an interconnect between the
chipset and the Integrated Base Board Management Controller (BMC) as well as providing support for the
optional Trusted Platform Module (TMP).
3.3.2 Universal Serial Bus (USB) Controller
The chipset has two Enhanced Host Controller Interface (EHCI) host controllers that support USB high-speed
signaling. High-speed USB 2.0 allows data transfers up to 480 Mb/s which is 40 times faster than full-speed
USB. The server board utilizes nine USB 2.0 ports from the chipset. All ports are high-speed, full- speed, and
low-speed capable.
• Four external USB ports are provided in a stacked housing located on the rear I/O section of the server
board
• Two USB ports are routed to an internal 10-pin connector that can be cabled for front panel support
• One internal Type ‘A’ USB port
• One eUSB connector intended for use with an optional eUSB SSD device
• Two USB ports are routed to the BMC
3.3.3 Embedded Serial ATA (SATA)/Serial Attached SCSI (SAS)/RAID Support
The Intel
®
C602 chipset provides storage support from two integrated controllers: AHCI and SCU. By default
the server board will support up to 6 SATA ports: Two single 6Gb/sec SATA ports routed from the AHCI
controller to the two white SATA connectors labeled “SATA-0” and “SATA-1”, and four 3Gb/sec SATA ports
routed from the SCU to the mini-SAS connector labeled “SCU_0 (0-3)”.
Note: The mini-SAS connector labeled “SCU_1 (4-7)” is NOT functional by default and is only enabled with the
addition of an Intel
®
RAID C600 Upgrade Key option supporting 8 SAS/SATA ports.
The server board is capable of supporting additional chipset embedded SAS, SATA, and RAID options when
configured with one of several available Intel
®
RAID C600 Upgrade Keys. Upgrade keys install onto a 4-pin
connector on the server board labeled “STOR_UPG_KEY”.
