QSSC-S4R Technical Product Specification I/O Riser
59
5. I/O Riser
5.1 I/O Riser Features
The I/O riser board provides most of the systems rear I/O including four GbE LAN ports, serial and video connectors. In
addition, the optional advanced server management upgrade kit with mounting and connections supports the Intel®
RMM3 LAN management module.
The I/O riser board supports the following features:
y Board size: 4.41” x 6.6”, ½ length PCIe
y Two Intel® 82576 PCIe* based Ethernet controllers (Kawela) provides advanced networking control capability.
Key features of Intel® 82576 network controller (Kawela) include:
- Two PCI Express interface (x2), 2.5 Gbps
- Two fully integrated GbE Media Access Control (MAC) and physical layer (PHY) ports
- Support Ethernet interfaces of 10BASE-T, 100BASE-TX and 1000BASE-T
- Support generation two Intel® I/O Acceleration Technology (Intel® I/OAT 2) capability
- Support Intel® VT-c, VMDq, PCI-SIG, SR-IOV & IPsec
y Support rear I/O: four gigabit Ethernet ports, one serial and one VGA (video) ports. The video signal comes from
BMC with supported VGA resolution to be 1600x1200.
y Integrated Baseboard Management Controller (IBMC – Pilot-ɛ): IBMC is a highly integrated single-chip solution,
integrating several devices typically found in servers. The following features are integrated into IBMC:
- Baseboard Management Controller (BMC)
- Server Class Super I/O (SIO)
- Graphic Controller
- Remote KVMS features
y Support advanced server management with the addition of a Intel® Remote Management Module 3 (Intel® RMM
3) installed on a custom I/O riser bracket with dedicated Ethernet maintenance port. The Intel® RMM3 NIC
provides an upgrade path to advanced server management capabilities. When the Intel RMM3 is plugged into the
I/O riser, the original set of server management features continue to function and additional functionality is
available. Refer to section 2.5.10 for Intel® RMM 3 module details.
y When installed with RMM3, support advanced remote manageability for KVM (Keyboard, Video & Mouse)
redirect, media redirect, USB 2.0 redirect, and can use IPMB bus interface to remotely shut down the host system
via a remote machine.
y Support sensor system management buses for field replaceable unit (FRU)
y Temperature sensor
y Chassis intrusion
