Server Board Features

At the heart of the system is a dual-processor serverboard based on the Intel C612 platform
controller hub (PCH) chipset and designed to provide maximum performance. The main features
of the serverboard are described in the following subsections.

Processors

The serverboard supports two multi-core Intel® Xeon™ E5-2600(v3) Series processors. Each
processor sits in an LGA 2011 socket and is interconnected via double Intel QuickPath
Interconnect (QPI) link support; see the next subsection for more information on the QPI
interconnects. Twelve DDR4 DIMM slots are available per CPU socket with three DIMM slots
per channel. A direct media interface connects the node’s PCH ASIC to processor 1; while 40-lane
Gen-3 PCIe interconnect lines link both processors directly to the motherboard LAN ports.

QPI Interconnect

Double QPI link pairs connect the two processors together on the motherboard, providing
processor-controlled transfer bandwidths of up to 9.6 GB/second per QPI link between sockets.

Each QPI comprises two 20-lane point-to-point data links, one in each direction (full duplex), with
a separate clock pair in each direction, for a total of 42 signals. Each signal is a differential pair,
so the total number of pins is 84. The 20 data lanes are divided onto four “quadrants” of 5 lanes
each. The basic unit of transfer is the 80-bit “flit”, which is transferred in two clock cycles (four
20 bit transfers, two per clock.) The 80-bit “flit” has 8 bits for error detection, 8 bits for “link-layer
header” and 64 bits for “data”. QPI bandwidths are advertised by computing the transfer of 64 bits
(8 bytes) of data every two clock cycles in each direction

Memory

The serverboard has 24 DIMM slots (twelve per processor) that support DDR4
2133/1866/1600/1333 MHz (L)RDIMMs. Up to three DIMMs per channel are supported.

Important: Use of three DIMMs per channel will limit the DIMMs to run at 1600 MHz
maximum. Always use DIMMs that are the same type and speed for best performance.

Note also that memory speed support is dependent on the type of CPUs used on the mother board.

4 007-6388-001

1: Introduction

Serial ATA and Optional SAS

The Intel PCH C612 is integrated into the system serverboard to provide an internal four-port or
ten-port SATA disk subsystem. The drive ports are SATA 3.0 ports. The hot-swappable SATA
drives are connected to a backplane that provides power, bus termination and configuration
settings. Optional RAID 0, 1, 5, 6 and 10 are supported. Note that your operating system must have
RAID support enabled to accommodate hot swapping of disk drives.

SAS RAID drive configurations require use of optional hardware ordered when the system is
purchased. Check with your sales or service representative to obtain information on set-up
procedures if your system did not come pre-configured with SATA or SAS RAID.

PCI Express Expansion Slots

The dual processor serverboard has two PCIe 3.0 x16 slots to support internal double-width PCIe
cards. Another PCIe riser at the rear of the server supports one external-facing PCIe 3.0 x8
low-profile card and one internal low-profile PCIe 3.0 x8 card.

See the section “PCIe Expansion Cards” in Chapter 5 for more information on these topics.

Onboard Controllers/Ports

The color-coded I/O ports include (an internal COM header located on the serverboard), VGA
(monitor) port, RJ45 LAN ports and two external USB 3.0 ports. A dedicated external IPMI LAN
port is also included.

Onboard Graphics Controller

The dual-processor serverboard features an integrated Aspeed AST2400 video controller
providing a DDR3 2D video graphics interface through the system VGA connector. The AST
video controller in the 1U server features PCIe 1x support, advanced BMC features, low power
consumption, high reliability and 1920 x 1200 60Hz display capability.

IPMI

IPMI (Intelligent Platform Management Interface) is a hardware-level interface specification that
provides remote access, monitoring and administration for your SGI C1104-GP2/C1110-GP2

Server Chassis Features

007-6388-001 5

server platforms. IPMI allows server administrators to view a server’s hardware status remotely,
receive an alarm automatically if a failure occurs, and power cycle a system that is non-responsive.

Other Features

Other on-board features that promote system health include on-board voltage monitors, a chassis
intrusion header, auto-switching voltage regulators, chassis and CPU overheat sensors, virus
protection and BIOS rescue.

Server Chassis Features

The following subsections provide a general outline of the main features of the SGI Rackable
C1104-GP2/C1110-GP2 server chassis.

System Power

The Rackable C1104-GP2/C1110-GP2 1U server chassis features a redundant power supply
composed of two separate power modules. This power redundancy feature allows you to replace
a failed power supply without shutting down the system. Note that each power supply provides up
to 750 Watts of power to the system.

Serial ATA Subsystems

The server chassis supports up to four 3.5-in or ten 2.5-inch SATA drives. Chassis drives are SATA

3.0 6-Gb/second slots. RAID 0, 1, 5, 6 and 10 drives are hot-swappable units and are connected
to a backplane that provides power and control. Note that the operating system you have installed
must support RAID to enable the hot-swap capability of RAID drives. Certain RAID levels may
require use of optional hardware or software to support RAIDed hard disk drives in the server. Use
of certain RAID combinations may limit the number of drives in an array.

Front Control Panel

The control panel on the C1104-GP2/C1110-GP2 server provides you with system monitoring and
control. LEDs that indicate system power, HDD activity, network activity, system overheat and a

system overheat/fan-fail/ UID LED. A main power button and a system reset button are also
included.

Serverboard and PCIe Subsystem

The C1104-GP2/C1110-GP2 server chassis is an ATX form factor chassis designed to be used in
a 1U rackmount configuration. The serverboard’s I/O backplane supports up to three standard size
(double-width) and one half-height PCIe cards which can offer optional computing solutions. A
15-pin VGA port, two USB 3.0 ports, Gigabit LAN ports and a dedicated RJ-45 IPMI LAN port
are also supported.

Important: Check with your SGI sales or service representative prior to using any PCIe device
not sourced from the SGI factory or documented by SGI as a supported option.

Figure 1-2 on page 7 shows a general block diagram of the C1104-GP2/C1110-GP2 server’s

processor and I/O chipset.

Cooling System

The 1U server chassis has a cooling design that includes ten internal 4-cm counter-rotating Pulse
Width Modulated (PWM) system cooling fans located in the chassis. An air shroud channels the
airflow from the system fans to efficiently cool the processor and PCIe areas of the system. Each
power supply module also includes an internal cooling fan. All chassis and power supply fans
operate continuously.

This chapter provides a quick setup checklist to get the SGI Rackable C1104-GP2/C1110-GP2
operational. If your system came already mounted in a rack, you can skip the rack installation
procedures.

Unpack the System

Inspect the shipping container that the C1104-GP2/C1110-GP2 was shipped in and note if it was
damaged in any way. If the server shows damage, file a damage claim with the carrier who
delivered it.

Decide on a suitable location for the rack that supports the weight, power requirements, and
environmental requirements of the C1104-GP2/C1110-GP2 server. It should be situated in a clean,
dust-free environment that is well ventilated. Avoid areas where heat, electrical noise, and
electromagnetic fields are generated. Place the server rack near a grounded power outlet. Refer
also to “System Warnings and Precautions” on page 10.

Prepare for Setup

The shipping container should include two sets of rail assemblies, two rail mounting brackets and
the mounting screws that you will use to install the system into a rack. Note that the inner rails
should already be attached to the server. Read this section in its entirety before you begin the
installation procedure.

Choose a Setup Location

Leave enough clearance in front of the rack to enable you to open the front door completely (~25
inches) and approximately 30 inches of clearance in the back of the rack to allow for sufficient
airflow and ease in servicing. This clearance may vary depending on the type of rack and
installation site chosen. This product is for installation only in an (IEC 60950) Restricted Access

Compliance” in Appendix B.

System Warnings and Precautions

Warning: The SGI Rackable C1104-GP2/C1110-GP2 server weighs up to 34.1 lbs (15.5

kg). Always use proper lifting techniques when you move the server. Always get the
assistance of another qualified person and/or mechanical lift device when you install the
sever. Failure to do so may result in serious personal injury or damage to the equipment.

Warning: Extend the leveling jacks on the bottom of the rack to the floor with the full

weight of the rack resting on them. Failure to do so can result in serious injury or death.

Warning: Attach stabilizers to the rack in single rack installations. Failure to do so can

result in serious injury or death. Couple racks together in multiple rack installations.
Failure to do so can result in serious injury or death.

Warning: Be sure the rack is stable before extending a component from the rack. Failure

to do so can result in serious injury or death.

Warning: Extend only one rack component at a time. Extending two or more components

simultaneously may cause the rack to tip over and result in serious injury or death.

2: Server Installation

Server Precautions

• Review the electrical and general safety precautions.

• Determine the placement of each component in the rack before you install the rails.

• Install the heaviest server components in the bottom of the rack first, and then work up.

• Add a regulating uninterruptible power supply (UPS) to protect the server from power
surges and voltage spikes and to keep your system operating in case of a power failure.

• Allow the hot-pluggable disk drives and power supply modules to cool before touching.

• Always keep the rack’s front door and all panels and components on the servers closed when
not servicing to maintain proper cooling.

• The server is not considered suitable for visual display work place devices under the German
government ordinance for work with visual display units.

Rack Mounting Considerations

Use the guidelines provided in the following subsections to properly install the server in a rack.

Ambient Operating Temperature

If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack
environment may be greater than the ambient temperature of the room. Therefore, consideration
should be given to installing the equipment in an environment compatible with the manufacturer’s
maximum rated ambient temperature (

35º C or 95º F).

Important: Certain system configurations using higher-wattage processors and PCIe option
cards may require the maximum rated ambient temperature of the operational environment be 30º
C (86º F) or lower. Altitude of operation can also affect required ambient air temperatures, see

Table B-1 on page 61. Check with your SGI sales or service representative for additional

information on this topic.

Install the System into a Rack

007-6388-001 13

Reduced Airflow

Equipment should be mounted into a rack so that the amount of airflow required for safe operation
is not compromised.

Mechanical Loading

Equipment should be mounted into a rack so that a hazardous condition does not arise due to
uneven mechanical loading. Racks should generally be filled with equipment from the bottom up.

Circuit Overloading

Consideration should be given to the connection of the equipment to the power supply circuitry
and the effect that any possible overloading of circuits might have on over-current protection and
power supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.

Reliable Ground

A reliable ground must be maintained at all times. To ensure this, the rack itself should be
grounded. Particular attention should be given to power supply connections other than the direct
connections to the branch circuit (for example, the use of power strips, and so on).

Install the System into a Rack

This section provides information on installing the C1104-GP2/C1110-GP2 into a rack. If the
system has already been mounted into a rack, refer to “Supply Power to the System” on page 19.
There are a variety of rack units on the market, which may mean the assembly procedure will
differ slightly. You should also refer to the installation instructions that came with the rack unit
you are using. Note that this system’s rail kit is designed to fit a rack between 26-in and 33.5-in
deep.

Separate the Sections of the Rack Rails

The chassis package includes two rail assemblies in the rack mounting kit.

14 007-6388-001

2: Server Installation

Each assembly consists of two sections: an inner fixed chassis rail that secures directly to the
server chassis and an outer fixed rack rail that secures directly to the rack itself. Note that the inner
rail may be pre-installed on the server by the SGI factory making separation steps unnecessary.

To separate the inner and outer rails, perform the following steps:

1. Locate the rail assembly in the chassis packaging as shown in Figure 2-2.

2. Extend the rail assembly by pulling it outward.

3. Press the quick-release tab

4. Separate the inner rail from the outer rail assembly.

Inner Rail Extensions

The chassis includes a set of inner rack rails in two sections:

• inner rails

• inner rail extensions

The inner rails are pre-attached to the server chassis and do not interfere with normal use of the
system if you decide not to install it into a server rack. Attaching the inner rail extensions to the
inner rails stabilizes the chassis within the rack is described in the following subsection.

Installing the Inner Rail Extensions

1. Place the inner rail extensions over the pre-attached inner rails which are attached to the side

of the chassis. Align the hooks of the inner rail with the rail extension holes. Make sure the
extension faces “outward” just like the inner rail, reference Figure 2-3.

2. Slide the extension toward the front of the chassis.

3. Secure the chassis to the rails with screws.

4. Repeat steps 1-3 for the other inner rail extension.

Figure 2-3 Rail to Server Chassis Attachment Example

16 007-6388-001

2: Server Installation

Assembling the Outer Rails

Each outer rail is in two sections that must be assembled before mounting on to the rack.

Assembling the Outer Rails

1. Identify the left and right outer rails by examining the ends, which bend outward.

2. Slide the front section of the outer rail into the rear section of the outer rail.

3. The assembly should look similar to the example in Figure 2-4 on page 16.

Figure 2-4 Outer Rail Assembly Example

Attaching the Outer Rack Rails

Outer rails attach to the rack and hold the chassis in place. They extend between 26.5 and 36.4
inches.

1. Measure the depth of the rack (distance from the front rail to the rear rail) to ensure it
complies with the limitations listed.

2. Adjust the outer rails to the proper length to fit within the rack. See the placement example in

Figure 2-5 on page 17.

Install the System into a Rack

007-6388-001 17

3. Hang the hooks of the front of the outer rail onto the slots on the front of the rack. Use

screws to secure the outer rails to the rack.

4. Pull out and adjust both the short and long brackets to the proper distance so that the rail can

fit snugly into the rack, reference Figure 2-6 on page 19.

5. Hang the hooks of rear portion of the outer rail into the slots on the rear of the rack. Secure

the long bracket to the rear side of the outer rail with the screws provided.

6. Repeat the previous steps to properly install the left outer rail.

Figure 2-5 Outer Rack Rail Assembly/Placement Example

2: Server Installation

Using the Rail Locking Tabs

Both chassis rails have a locking tab, which serves two functions:

• The tabs can lock the server into place when installed and pushed fully into the rack, (its
normal operating position).

• The tabs also lock the server in place when fully extended from the rack. This prevents the
server from coming completely out of the rack when pulled out for servicing. Depress both
tabs at the same time to fully remove the server from its rail mounting and extract it from the
rack.

Install the Server in a Rack

Warning: The SGI Rackable C1104-GP2/C1110-GP2 server weighs up to 34.1 lbs (15.5

kg) Always use proper lifting techniques when your move the server. Always get the
assistance of another qualified person and/or a mechanical lifting device when you install the
sever. Failure to do so may result in serious personal injury or damage to the equipment.

1. Extend the outer rails on either side of the rack rail assembly.

2. Align the inner rails of the chassis with the outer rails on the rack, see Figure 2-6.

Figure 2-6 Installing the Server in the Rack

3. Slide the inner rails into the outer rails, keeping the pressure even on both sides. When the

chassis has been pushed completely into the rack, it should click into the locked position.

4. Optional screws are recommended to secure and hold the front of the chassis to the rack.

Supply Power to the System

Connect the power cords from the power supply modules into a power strip or power distribution
unit (PDU) within the rack. An optionally available uninterruptible power supply (UPS) can
ensure continued operation in case of a failure of the regular power source.

Control Panel Buttons

In addition to monitoring the activity and health of specific components using LEDs, the system
uses two buttons located on the front of the chassis: a reset button and a power on/off button. Use
the reset button to reboot the system as shown in Figure 3-3.

Figure 3-3 System Reset Button

Figure 3-4 shows the main power button, which is used to apply or turn off the main system power.

Turning off system power with this button removes the main power but keeps standby power
supplied to the system.

Figure 3-4 System Power On Button

Control Panel LEDs

007-6388-001 23

Control Panel LEDs

The control panel located on the front of the chassis has several LEDs. These LEDs provide you
with critical information related to different parts of the system. This section explains what each
LED indicates when illuminated or flashing and any corrective action you may need to take.

Power Fail LED

The power fail LED indicates a power supply module has failed as shown in Figure 3-5. The
second power supply module will take the load and keep the system running but the failed module
will need to be replaced as soon as possible. Refer to Chapter 6 for details on replacing the power
supply. This LED should be off when the system is operating normally.

Figure 3-5 Power Fail LED Example

UID LED

When the UID LED flashes (shown in Figure 3-6), it indicates a remote activation of the UID. The
“blue light” function (UID) of this LED is used to identify a specific server in large racks filled
with equipment. When activated locally the LED stays on solid blue. When activated through the
system software the “blue light” will remain on until shut down by the administrator. There is a
UID indicator on both the front and rear of the server.

Figure 3-6 UID LED Example

NIC1

When flashing, the NIC1 LED indicates network activity on the LAN1 port (see Figure 3-7).

24 007-6388-001

3: System Interface

Figure 3-7 LAN1 Network Activity NIC1 LED Example

NIC2

When flashing, the NIC2 LED indicates network activity on the LAN2 port (see Figure 3-8).

Figure 3-8 LAN2 Network Activity NIC2 LED Example

HDD

The HDD LED indicates hard drive activity when flashing (see Figure 3-9).

Figure 3-9 Hard Drive Activity LED Example

Info LED

The info LED can indicate multiple states that may require attention. An example LED
designation is shown in Figure 3-10. This LED has several states:

• If the LED shows a solid red it indicates an overheat condition - check the environmental
temperature and look for “cable congestion” or other obstructions that might impede air flow
to the server.

Drive Carrier LEDs

007-6388-001 25

• A slow red blink indicates a power failure - check the function of the system power supplies

at the back of the unit.

• A fast red blink indicates a fan failure - check for a failed cooling fan and replace as soon as

possible.

Figure 3-10 Overheat/Fan Fail/Info LED Example

Drive Carrier LEDs

The system hard disk drives each have two LEDs, that function as listed in the following two
paragraphs:

• Green: When illuminated, the green LED on the drive carrier indicates drive activity. A

connection to the drive backplane enables this LED to blink on and off when that particular
drive is being accessed. Please refer to Chapter 6 for instructions on replacing failed drives.

• Red: When this LED is flashing it indicates that a RAID drive is rebuilding. A solidly lit red

LED indicates a drive failure. If the drives fails, you should be notified by your system
management software. Refer to Chapter 6 for instructions on replacing failed drives.

Chapter 4

4. System Safety

This chapter describes basic safety precautions when using the server.

Electrical Safety Precautions

Basic electrical safety precautions should be followed to protect yourself from harm and the
Rackable C1104-GP2/C1110-GP2 system from damage, as follows:

• Be aware of the locations of the power on/off switch on the chassis as well as the room's

emergency power-off switch, disconnection switch or electrical outlet. If an electrical
accident occurs, you can then quickly remove power from the system.

• Do not work alone when working with high voltage components.

• Power should always be disconnected from the system when removing or installing main

system components, such as the memory modules and disk drives. When disconnecting
power, you should first power down the operating system and then unplug the power cords.
The unit can have more than one power supply cord. Disconnect two power supply cords
before servicing to avoid electrical shock.

• When working around exposed electrical circuits, another person who is familiar with the

power-off controls should be nearby to switch off the power if necessary.

• Use only one hand when working with powered-on electrical equipment. This is to avoid

making a complete circuit, which will cause electrical shock. Use extreme caution when
using metal tools, which can easily damage any electrical components or circuit boards they
come into contact with.

• Do not use mats designed to decrease static electrical discharge as protection from electrical

shock. Instead, use rubber mats that have been specifically designed as electrical insulators.

• The power supply power cords must include a grounding plug and must be plugged into

grounded electrical outlets or power distribution unit (PDUs).

28 007-6388-001

4: System Safety

Serverboard Battery

Caution: There is a danger of explosion if an onboard battery is installed upside down, which
will reverse its polarities (see the example in Figure 4-1). This battery must be replaced only
with the same or an equivalent type recommended by the manufacturer. Check with your
service representative if you have any questions.

Figure 4-1 Installing the Onboard Battery Example

Important: Handle used batteries carefully and do not damage the battery in any way; a damaged
battery may release hazardous materials into the environment. Do not discard a used battery in the
garbage or a public landfill. Dispose of used batteries according to the manufacturer's instructions
and in compliance with the regulations set up by your local hazardous waste management agency.

ESD Precautions

Caution: This server contains electronic components and printed circuit boards which are
susceptible to electrostatic discharge (ESD) damage. ESD is generated by two objects with
different electrical charges coming into contact with each other. An electrical discharge is
created to neutralize this difference, which can damage electronic components and printed
circuit boards.

!

!

General Safety Precautions

007-6388-001 29

The following measures are generally sufficient to neutralize this difference before contact is
made to protect your equipment from ESD:

• Use a grounded wrist strap designed to prevent static discharge.

• Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready for

use.

• Touch a grounded metal object before removing the board from the antistatic bag.

• Do not let components or PCBs come into contact with your clothing, which may retain a

charge even if you are wearing a wrist strap.

• Handle a board by its edges only; do not touch its components, peripheral chips, memory

modules or contacts.

• When handling chips or modules, avoid touching their pins.

• Put the serverboard and peripherals back into their anti-static bags when not in use.

• For grounding purposes, make sure your computer chassis provides excellent conductivity

between the power supply, the case, the mounting fasteners and the serverboard.

Mainboard Replaceable Soldered-in Fuses

Important: If your system comes with self-resetting PTC (Positive Temperature Coefficient)
fuses on the serverboard, they must be replaced by trained service technicians only. The new fuse
must be the same or equivalent as the one replaced. Contact your technical support organization
for details and support.

General Safety Precautions

Follow these rules to ensure general safety:

• Keep the area around the C1104-GP2/C1110-GP2 systems clean and free of clutter.

• The Rackable C1104-GP2/C1110-GP2 system can weigh approximately 34.1 lbs (15.5 kg.)

when fully loaded. When lifting the system, two people at either end should lift slowly with
their feet spread out to distribute the weight. Always keep your back straight and lift with
your legs.

30 007-6388-001

4: System Safety

• Place the chassis top cover and any system components that have been removed away from
the system or on a table so that they won't accidentally be stepped on.

• While working on the system, do not wear loose clothing such as neckties and unbuttoned
shirt sleeves, which can come into contact with electrical circuits or be pulled into a cooling
fan.

• Remove any jewelry or metal objects from your body, which are excellent metal conductors
that can create short circuits and harm you if they come into contact with printed circuit
boards or areas where power is present.

• After accessing the inside of the system, close the system back up and secure it to the rack
unit with the retention screws after ensuring that all connections have been made.

Hard Drives (C1104-GP2 and C1110-GP2 Chassis)

The C1104-GP2 chassis option supports a maximum of four 3.5-inch hard disk drives, see

Figure 5-3 for an example. Install the drives from left to right starting in the left bay.

The C1110-GP2 chassis option supports a maximum of ten 2.5-inch hard drives, see Figure 5-4
for an example. Install drives from left to right starting in the lower-left bay.

All drive bays must be populated with either a drive or a “drive blank” to maintain system
thermals. Failure to follow this guideline may cause system overheating and thermal shutdown of
the unit.

Important: The operating system you use must have RAID support to enable the hot-swap
capability and RAID functions of the drives.

Drive Configurations

The disk drive RAID configurations supported in the Rackable C1104-GP2/C1110-GP2 servers
are outlined in the paragraphs that follow. Note that some configurations are dependent on use of
optional hardware to support RAID configurations.

38 007-6388-001

5: System and Serverboard Information

The supported disk drive configurations are as follows:

• JBOD
This non-RAID disk array supports any number of drives installed in the server. The
operating system is placed on the disk drive in location 0 (system disk). All other drives are
data drives.

• RAID 0
Disk striping without parity, supports any even-number of drives installed. Note that all
drives must be the same type, speed and capacity. The operating system will be striped
across all drives in the system. This configuration is not recommended.

• RAID 1
Disk “mirroring”, supports exactly two drives. The two drives represent one RAID 1 logical
drive. The operating system will be installed on the drives located in Drive positions 0 and 1.

Note that both drives 0 and 1 must be of the same type, speed and capacity.

• RAID 5
Disk striping with distributed parity - each RAID 5 drive has its own parity resource. Up to
20% of disk space on each drive must be devoted to parity information. A minimum of three
drives are required for a functional RAID 5 array. A single drive failure will result in
decreased performance until the damaged drive is replaced and the parity rebuild is
complete. RAID 5 is generally favored in a “read-heavy” data environment as write
operations will execute at a slower rate. Optional hardware is required to support RAID 5.

Note that all drives must be the same type, speed and capacity.

RAID 6
RAID 6 enhances RAID 5 style disk striping parity distribution by creating enough parity
data to handle two disk failures. You can lose a disk and have an unrecoverable error (URE)
during reconstruction and still reconstruct your system data. Calculations for the RAID 6
parity stripes are more complicated than those for RAID 5; virtually doubling the workload
for the processor on the RAID controller and exacting a performance penalty on write
operations. Up to 40% of data space on each disk must be devoted to RAID 6 parity
information. Optional hardware is required to support RAID 6 functionality.

Note that all drives must be the same type, speed and capacity.

• RAID 10
Mirrored disk striping, the data is striped across one set of drives and then mirrored on
another set of drives. A minimum of four drives of the same type are required. The total
number of drives must be an even number (4 or 8). A total of four drives is a 2+2 and a total

PCIe Expansion Cards

007-6388-001 39

of 8 drives is a 4+4 configuration. The operating system will be striped across the drives in
the primary set and then mirrored on the secondary set of drives.

Note that all drives must be the same type, speed and capacity.

PCIe Expansion Cards

There are two internal double-width PCIe 3.0 x16 expansion slots, one PCIe 3.0 x8 low-profile
internal slot and one external PCIe slot available with the C1104-GP2/C1110-GP2 servers. The
external option slot functions as listed:

• External PCI-Express 3.0 x8 low-profile card (x16 slot)

Note: Only specific cards will fit and function in the internal PCIe slots, contact your SGI sales
or service representative for information on approved cards.

Power Supply Functional Rating

The C1104-GP2/C1110-GP2 server default configuration is two rear-installed 750-Watt power
supplies. The second power supply acts as a redundant power unit for the server. The supplies are
“auto-ranging” and can operate from either 100-140V or 180-240V levels at 50 or 60Hz.

Each power supply module has its own cooling fan.

The supplies used have a Platinum Certification rating.

Chapter 6

6. Basic Troubleshooting and Chassis Service

Use the procedures in the first half of this chapter to troubleshoot your system. If you follow all
of the procedures and still need assistance, check with your authorized support organization.

The subsections in the second half of this chapter starting with “Chassis Service Information” on

page 43 are intended to guide you through basic component remove and replace procedures.

Basic Troubleshooting Procedures

Use the information in the following subsections to remedy basic problems you might encounter
when working with the SGI Rackable C1104-GP2/C1110-GP2 server.

If the System Does Not Power Up

If the system will not power up when the front power button is pushed, use the following checklist
to identify common sources for the problem:

• Make sure that both ends of each system power cable are firmly connected to the power

supplies and the corresponding power source(s) or power distribution unit (PDU).

• Check to see if the power fail LED is lit on the front of the unit. This LED should be off if

the system is operating normally.

• Check that the LED on each power supply is properly lit. The power supply has one status

LED located on the left side of the front of the power supply. The LED has three states:

– Dark or off - indicates no AC power present

– Solid Amber - AC power is present, the server is not turned on (no DC power)

– Blinking Amber - supply temperature exceeds 63

o

C (auto-shutdown occurs at 73o C)

– Solid Green - AC power is present and the server is turned on (DC power present)

42 007-6388-001

6: Basic Troubleshooting and Chassis Service

• Open the system cover, remove the air shroud and check to make sure that no obvious short
circuits exist between the serverboard and chassis.

System Powers Up But Will Not Boot

If the system powers up but will not boot the Operating System, check the following:

• Check the system order document(s) - the C1104-GP2/C1110-GP2 server may have been
ordered with no operating system. If so, check with your system administrator for OS
loading information.

• Check the system disk (drive 0) for drive activity and confirm that it is firmly seated in the
disk bay. A red light on the front of the disk indicates a functional error. Check with your
service provider or local system administrator.

No Video After System Power Up

If the system powers up and appears to be booting normally but no video is present, try the
following basic solutions:

• Confirm your monitor is plugged in and switched on.

• Check all video cables and ensure they are properly connected.

• Listen for a BIOS “beep code” error message - one long beep plus 8 short beeps indicates a
video error. This beep code message could indicate a video memory error or other video
malfunction; contact your service provider.

• If using an optional PCIe video card check the back of the card for LED activity or a fault
indicator. Try opening the system, reseating the PCIe card and rebooting; see the section

“Install/Replace a PCIe Expansion Card” on page 57.

If you cannot get a video signal after trying basic solutions contact your support provider.

Memory Errors

If your system experiences memory related errors, try these basic troubleshooting steps to resolve
or better identify the problem:

• Confirm that the power supply LED is not indicating an error.

Chassis Service Information

007-6388-001 43

• Listen for memory error beep codes - five short beeps followed by one long beep is a BIOS

signal that no system memory has been detected - See Appendix A, “BIOS Error Codes”.

• Shut the system down, remove the covers over the serverboard and make sure that all the

DIMM modules are properly and fully installed.

• You should be using registered ECC DDR4 memory. Also, it is recommended that you use

the same memory type and speed for all DIMMs in the system.

• Contact your administrator or support provider if the memory errors continue.

Chassis Service Information

The following sections cover the steps required to install components and perform maintenance
on the C1104-GP2/C1110-GP2 chassis. For component installation, follow the steps in the order
given to eliminate the most common problems encountered. If some steps are unnecessary, skip
ahead to the step that follows. Drive placement and physical size will differ between the
C1104-GP2 chassis (four 3.5-inch drive slots) and C1110-GP2 (ten 2.5-inch drive slots).

Important: Always disconnect the AC power cord(s) before adding, changing or installing any
internal hardware components.

Tools Required: The only tool you will need to install components and perform maintenance is a
Phillips screwdriver.

Static-Sensitive Devices

Electrostatic discharge (ESD) can damage electronic components. To prevent damage to any
printed circuit boards (PCBs), it is important to handle them very carefully. The following
measures are generally sufficient to protect your equipment from ESD damage.

Precautions

• Use a grounded wrist strap designed to prevent static discharge.

• Touch a grounded metal object before removing any board from its anti-static bag.

44 007-6388-001

6: Basic Troubleshooting and Chassis Service

• Handle a board by its edges only; do not touch its components, peripheral chips, memory
modules or gold contacts.

• When handling chips or modules, avoid touching their pins.

• Put the serverboard, add-on cards and peripherals back into their anti-static bags when not in
use.

• For grounding purposes, make sure your computer chassis provides excellent conductivity
between the power supply, the case, the mounting fasteners and the serverboard.

Unpacking

Replacement components are usually shipped in anti-static packaging to avoid static damage.
When unpacking an upgrade or replacement component, make sure the person handling it is static
protected.

Control Panel

The control panel (located on the front of the chassis) must be connected to the JF1 connector on
the serverboard to provide you with system status indications. A ribbon cable has bundled these
wires together to simplify the connection. Connect the cable from JF1 on the serverboard to the
Control Panel PCB (printed circuit board). Make sure the red wire plugs into pin 1 on both
connectors. Pull all excess cabling out of the airflow path. The LEDs inform you of system status.
See Chapter 3 for details on the LEDs and the control panel buttons.

Drive Bay Installation/Removal

This section describes hard drive installation and removal.

Accessing the Drive Bays

Drives: You do not need to access the inside of the chassis or remove power to replace or swap a
RAIDed hard disk drive. Data may be lost or corrupted if you “hot swap” a JBOD disk drive. Shut
down system power before removing or replacing a JBOD disk. Removing either a RAID or
JBOD drive without replacing it may cause system errors. Proceed to the next section for further
hard drive instructions.

Drive Bay Installation/Removal

007-6388-001 45

Note: You must use approved hard-disk or SSD drives in the system.

Removing Hard Drives or Carriers from the Chassis

1. Press the release button on the drive carrier. This extends the drive carrier handle.

2. Use the handle to pull the drive carrier out of the chassis.

Important: Empty carriers without drives must stay in the chassis during operation for proper
airflow/cooling purposes except during remove/replace operations. Do not operate the server with
carriers removed.

The Hard Drive Backplane

The hard drives plug into a backplane that provides power, drive ID and bus termination. A RAID
controller and/or optional RAID software can be used with the backplane to provide data security.
The operating system you use must have RAID support to enable the hot-swap capability of the
hard drives. The backplane is preconfigured, so no jumper/switch configuration is required.

Caution: Be careful when working around the drive backplane. Do not touch the backplane with
your fingers or any metal objects and make sure no ribbon cables touch the backplane or obstruct
the holes, which aid in proper airflow.

Disk Drive Installation

The drives are mounted in drive carriers (Figure 6-1 on page 46) to simplify their installation and
removal from the chassis, see Figure 6-2 on page 46 for a disk removal example. These carriers
also help promote proper airflow for the drives. For this reason, even empty carriers without hard
drives installed must remain in the chassis during operation. See Figure 6-3 on page 48 for an
example drive carrier and the “dummy” drive blank used when a working disk is not installed in
a drive slot.

Drive Bay Installation/Removal

007-6388-001 47

Hard Drive Carrier Assembly Usage

1. Remove the four screws securing the dummy/bad drive to the hard drive carrier.

2. Insert a new/replacement hard drive into the carrier with the PCB side facing down and the

connector end toward the rear of the carrier.

3. Align the hard drive in the disk drive carrier so that the mounting holes of the carrier are

aligned with the mounting holes of the drive. Note that there are holes in the carrier which
are marked “SATA” to aid in correct installation.

4. Secure the drive to the carrier with four screws. Use the M3 flat-head screws included in the

HDD bag of your accessory box. Note: the screws used to secure a dummy drive to the
carrier should not be used to secure the hard drive.

5. Insert the hard drive carrier assembly into its bay vertically, keeping the carrier oriented so

that the release button is on the bottom. When the carrier reaches the rear of the drive bay,
the handle will retract.

6. Using your thumb, push against the upper part of the hard drive handle until the assembly

clicks into the locked (fully seated) position, see Figure 6-4 on page 49 for an example.

Note: Your operating system must have RAID support to enable the hot-plug capability of the
drives.

Caution: Regardless of how many hard drives are installed, all drive carriers must remain in the
drive bays to maintain proper airflow and system cooling.

6: Basic Troubleshooting and Chassis Service

Power Supply

The system offers a redundant power supply assembly consisting of two 750-Watt power modules.
Each power supply module has an auto-switching capability, which enables it to automatically
sense and operate at a 100V - 240V input voltage at 50 or 60Hz.

Power Supply Failure

If either of the two power supply modules fail, the other module will take the full load and allow
the system to continue operation without interruption. The PWR Fail LED will illuminate and
remain on until the failed unit has been replaced. The power supply units have a hot-swap
capability, meaning you can replace the failed unit without powering down the system, see

Figure 6-5 on page 51 for an example.

Removing/Replacing a Power Supply

You do not need to shut down the system to replace a failed power supply unit. The backup power
supply module will keep the system up and running while you replace the failed unit. Replace with
the same model.

Removing the Power Supply

1. First unplug the AC power cord from the failed power supply module.

2. Depress the locking tab on the power supply module.

3. Pull it straight out using the rounded handle.

Installing a New Power Supply

1. Replace the failed hot-swap unit with another identical power supply unit.

2. Push the new power supply unit into the power bay until you hear a click.

3. Secure the locking tab on the unit.

4. Finish by plugging the AC power cord back into the unit.

6: Basic Troubleshooting and Chassis Service

Accessing the Inside of the Chassis

1. Grasp the two handles on either side and pull the unit straight out until it locks (you will hear
a “click”).

2. Next, depress the two buttons on the top of the chassis to release the top cover and at the
same time, push the cover away from you until it stops. You can then lift the top cover from
the chassis to gain full access to the inside of the server.

Note: Normally you would power down the system before installing or removing internal
components - but it may be necessary to leave system power on to determine which fan has failed.

System Fans

Ten 4-cm counter-rotating fans provide the cooling for the system. Each fan unit is actually made
up of two fans joined back-to-back, which rotate in opposite directions. This counter-rotating
action generates exceptional airflow and works to dampen vibration levels. It is very important
that the chassis top cover is properly installed and making a good seal in order for the cooling air
to circulate properly through the chassis and cool the components.

System Fan Failure

Fan speed is controlled by system temperature via a BIOS setting. If a fan fails, the remaining fans
will ramp up to full speed and the overheat/fan fail LED on the control panel will flash. Replace
any failed fan as soon as possible with the same type and model (the system can continue to run
with a failed fan).

Your system administrator may be able to identify which fan has failed using the system BIOS.

If an administrator or service representative is not using the BIOS to determine which fan has
failed, you can remove the top chassis cover while the system is still running to determine which
of the fans has failed. After determining which is the failed fan, shut down and remove power from
the system by unplugging the server’s cords. Never run the server for an extended period of time
with the top cover open.

System Fans

007-6388-001 53

Replacing System Fans

This section describes how to remove or install a system fan.

Remove/Replace a Fan

1. If you have not already done so, remove the chassis cover to access the fans, see the example

in Figure 6-6 on page 54.

2. Turn off the power to the system and unplug the AC power cord.

3. Remove the failed fan's wiring connectors from the serverboard.

4. Remove and retain the four pins securing the fan assembly to the fan tray.

5. Lift the assembly housing the failed fan from the fan tray and out of the chassis, see the

example in Figure 6-7 on page 55.

6. Place the new fan into the vacant space in the fan tray, while making sure the arrows on the

top of the fan (indicating air direction) point in the same direction as the arrows on the other
fans in the same fan tray. See Figure 6-8 on page 56 for a fan assembly example.

7. Reconnect the fan wires to the exact same chassis fan headers as the previous fan.

8. Reconnect the AC power cord, power up the system and check that the fan is working

properly before replacing the chassis cover.

Use the following steps and illustration to install or replace a PCIe card at the rear of the system:

1. Remove the chassis cover and disconnect both the power cables from the server.

2. Confirm that you have the correct size and type of PCIe expansion card (low-profile).

3. Remove the screw securing the low-profile PCIe slot cover at the rear of the chassis and slide

it sideways to remove from the chassis.

4. Select the appropriate riser connector for your low-profile card. Note that the low-profile

riser card uses a x16 connector.

5. Align the PCIe card with the rear slot opening and the riser connector, then simultaneously

slide the rear bracket into place as you insert the PCIe connector into the riser.

6. Secure the rear bracket in the slot with the screw removed in step 3 and connect cables to the

A. BIOS Error Codes

During Power-On Self-Test (POST) routines, which are performed each time the system is
powered on, errors may occur.

Non-fatal errors are those which, in most cases, allow the system to continue the boot-up process.
The error messages normally appear on the screen.

Fatal errors are those which will not allow the system to continue the boot-up procedure. If a fatal
error occurs, you should consult with your system manufacturer for possible repairs.

These fatal errors are usually communicated through a series of audible beeps. The numbers on
the fatal error list (see Table A -1) correspond to the number of beeps for the corresponding error.
