Product Safety Overview

Heed safety instructions: Before working with your server product, whether you are using this guide or any other resource as a reference, pay close attention to the safety instructions. You must adhere to the assembly instructions in this guide to ensure and maintain compliance with existing product certifications and approvals. Use only the described, regulated components specified in this guide. Use of other products/components will void the UL listing and other regulatory approvals of the product and will most likely result in noncompliance with product regulations in the region(s) in which the product is sold.

Hazardous conditions, devices and cables: Hazardous electrical conditions may be present on power, telephone, and communication cables. Turn off the system and disconnect all telecommunications systems, networks, and modems attached to it before performing any service. Otherwise, personal injury or equipment damage can result.

Installing or removing jumpers: A jumper is a small plastic encased conductor that slips over two jumper pins. Some jumpers have a small tab on top that you can grip with your fingertips or with a pair of fine needle nosed pliers. If your jumpers do not have such a tab, take care when using needle nosed pliers to remove or install a jumper; grip the narrow sides of the jumper with the pliers, never the wide sides. Gripping the wide sides can damage the contacts inside the jumper, causing intermittent problems with the function controlled by that jumper. Take care to grip with, but not squeeze, the pliers or other tool you use to remove a jumper, or you may bend or break the pins on the board.

Electrostatic Discharge (ESD)

Electrostatic discharge can cause damage to your computer or the components within it. ESD can occur without the user feeling a shock while working inside the system chassis or while improperly handling electronic devices like processors, memory or other storage devices, and add-in cards.

Intel recommends the following steps be taken when performing any procedures described within this document or while performing service to any computer system.

•Where available, all system integration and/or service should be performed at a properly equipped ESD workstation.

•Wear ESD protective gear like a grounded antistatic wrist strap, sole grounders, and/or conductive shoes.

•Wear an anti-static smock or gown to cover any clothing that may generate an electrostatic charge.

•Remove all jewelry.

•Disconnect all power cables and cords before opening the Server Chassis

•Power down the system and remove power feed from the Server Board before performing any integration or service

•Touch any unpainted metal surface of the chassis before performing any integration or service.

•Hold all circuit boards and other electronic components by their edges only.

•After removing electronic devices from the system or from their protective packaging, place them component side up on to a grounded anti-static surface or conductive foam pad. Do not place electronic devices on to the outside of any protective packaging.

1.1Intel Server Board Use Disclaimer

Intel Corporation server boards support add-in peripherals and contain a number of high-density VLSI and power delivery components that need adequate airflow to cool. It is the responsibility of the system integrator to consult vendor datasheets and operating parameters to determine the amount of airflow required for a specific system configuration and operating environment. Intel Corporation cannot be held responsible if components fail or the server board does not operate correctly when used outside any of its published operating or non-operating limits.

4.3Memory RAS Features

Each processor within the Intel® Xeon® E-2200 processor family has support for advanced memory RAS features as defined in Table 5.

		Table 5. Memory RAS features
	RAS Feature	Description
		x8 Single Device Data Correction (SDDC) via static virtual
		lockstep (Applicable to x8 DRAM DIMMs)
		Adaptive Data Correction (SR) (Applicable to x4 DRAM DIMMs)
	Device Data Correction	x8 Single Device Data Correction + 1 bit (SDDC+1) (Applicable

Intel® Server Board M10JNP2SB User Guide

5.Server Board I/O

5.1PCIe Add-In Card Support

The server board provides three PCI Express* (PCIe*) slots labeled: “PCIe#1”, “PCIe#2”, and “PCIe#3”. The PCIe* interface of the Intel® Server Board M10JNP2SB is fully compliant with the PCIe* Base Specification, Revision 3.0 supporting the following PCIe* bit rates: 3.0 (8.0 GT/s), 2.0 (5.0 GT/s), and 1.0 (2.5 GT/s).

PCIe add-in card slots and their properties are as follows:

•Slot 1: PCIe* 3.0 x8 slot (x4 electrical)

•Slot 2: PCIe* 3.0 x8 slot (x8 electrical)

•Slot 3: PCIe* 3.0 x16 slot (x8 electrical)

5.1.1PCIe* Enumeration and Allocation

The BIOS assigns PCI bus numbers in a depth-first hierarchy, in accordance with the PCI Local Bus Specification, Revision 3.0. The bus number is incremented when the BIOS encounters a PCI-PCI bridge device.

Scanning continues on the secondary side of the bridge until all subordinate buses are assigned numbers. PCI bus number assignments may vary from boot to boot with varying presence of PCI devices with PCI-PCI bridges.

If a bridge device with a single bus behind it is inserted into a PCI bus, all subsequent PCI bus numbers below the current bus are increased by one. The bus assignments occur once, early in the BIOS boot process, and never change during the pre-boot phase.

The BIOS resource manager assigns the PIC-mode interrupt for the devices that are accessed by the legacy code. The BIOS ensures that the PCI BAR registers and the command registers for all devices are correctly set
