Intel server boards contain a number of high-density VLSI and power delivery components that need adequate
airflow for cooling. Intel's own chassis are designed and tested to meet the intended thermal requirements of these
components when the fully integrated system is used together. It is the responsibility of the system integrator that
chooses not to use Intel developed server building blocks to consult vendor datasheets and operating parameters to
determine the amount of airflow required for their specific application and environmental conditions. Intel Corporation
can not be held responsible if components fail or the server board does not operate correctly when used outside any
of their published operating or non-operating limits.

Preface
About this Manual
Thank you for purchasing and using the Intel® Server System SR2612UR. This guide
assumes you are familiar with Serial ATA (SATA) technology, SAS (Serial Attached
SCSI), computer hardware, data storage, and network administration terminology and
tasks.
This manual is written for system technicians who are responsible for troubleshooting,
upgrading, and repairing this server system. This document provides reference
information, feature information, and step-by-step instructions for adding and replacing
components in the server system. For the latest version of this manual, see
http://www.intel.com/support/motherboards/server/sr2612ur/.
Terminology Used in this Guide
Because this guide provides information that you can use to manage one or more storage
appliances in a variety of configurations, the generic term “storage system” is used to refer
to the controller, disk drives, JBOD expansion enclosures, and servers being used together
for data storage.
Many of the terms and concepts referred to in this guide are known to computer users by
multiple names. In this guide, this terminology is used:
•Controller (also known as an I/O module or I/O controller)
•Disk drive (also known as hard disk, hard drive, or hard disk drive including Drive
Carrier Assembly)
•HBA (also known as Host Bus Adapter, RAID controller/adapter, or SAS/SATA
Adapter)
•Storage Application Array (also known as an Intel® Server System SR2612UR)
Manual Organization

Warnings
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.
System power on/off: The power button DOES NOT turn off the system AC power. To
remove power from the system, you must unplug the AC power cord from the wall outlet.
Make sure the AC power cord is unplugged before you open the chassis, and add or
remove any components.
Hazardous conditions, devices and cables: Hazardous electrical conditions may be
present on power, telephone, and communication cables. Turn off the server and
disconnect the power cord, telecommunications systems, networks, and modems attached
to the server before opening it. Otherwise, personal injury or equipment damage can
result.
Electrostatic discharge (ESD) and ESD protection: ESD can damage disk drives,
boards, and other parts. We recommend that you perform all the procedures in this chapter
only at an ESD workstation. If one is not available, provide some ESD protection by
wearing an antistatic wrist strap attached to chassis ground any unpainted metal surface on
your server when handling parts.
ESD and handling boards: Always handle boards carefully. They can be extremely
sensitive to ESD. Hold boards only by their edges. After removing a board from its
protective wrapper or from the server, place the board component side up on a grounded,
static free surface. Use a conductive foam pad if available but not the board wrapper. Do
not slide board over any surface.
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.

multi-port PCI SAS card. Currently, the qualified and supported PCI RAID card are
Intel®RAID Controller SRCSASJV, Intel®RAID Controller SRCSASLS4I and Intel®
RAID Controller SASWT4I. Please refer to the Intel Customer Support web site under the
link for these RAID controllers at:http://www.intel.com/support/motherboards/server/
About the Disk Drives and Drive Carriers
The Intel®Server System SR2612UR supports up to 12 SAS and/or SATA disk drives.
SAS and SATA disk drives are not supported within the same appliance enclosure;
however, only in specific configurations (as shown later in this chapter).
Each disk drive is mounted on a drive carrier assembly (shown in the following figure)
with a push-button lever for quick installation and removal.

4Intel®Server System SR2612UR Service Guide
Figure 3. Intel®Server System SR2612UR Drive Carrier Assembly
Each drive carrier has three LEDs, which indicate status as described in “Monitoring the
Disk Drives”.
To maintain proper airflow and cooling inside the appliance, all drive slots must have
either a disk drive carrier assembly populated with an actual disk or a special plastic drive
blank installed. Under no circumstances should the appliance be operated with empty
drive slots or with empty drive carrier assemblies as this could cause damage to the LEDs
on the midplane and/or create thermal problems (as well as void the Limited Warranty).
Disk drives are hot-swappable.
Drive Slot Numbers
Figure 4. Intel®Server System SR2612UR Drive Slots
Warning: Disk drives spin at high speed.When removing a Disk Drive Carrier from an enclosure
with power on, unlatch the carrier and allow the drive to completely spin down for
approximately 15-20 seconds before sliding the carrier out of the enclosure. Removing the
Disk Drive Carrier assembly while the drive is spinning could cause injury and may cause
severe damage to the disk drive.

Intel®Server System SR2612UR Service Guide 5
Combining SATA and SAS Disk Drives
If you are combining SAS and SATA disk drives in the same enclosure, use the following
figures to plan where you will place the disk drives.
These figures represent enclosures fully-loaded with disk drives. However, the same
guidelines apply even if you are filling some of the drive slots with blank drive carriers.
