Optional IS2224 JBOD Storage

IS2224 JBODs are 2U, rack-mountable storage enclosures based on 6Gb/s SAS technology and
powered by the LSI SAS2x36 6Gb/s SAS expander IC. They offer hot-swappable drive bays that
support 3Gb/s and 6Gb/s SAS hard disk drives (HDDs) or solid-state drives (SSDs). The
following paragraphs and illustrations provide an overview of the IS2224 JBOD; for more detailed
information see the SGI InfiniteStorage IS2224 Installation and Overview Guide, P/N
007-5830-00x.

IS2224 JBOD Front-Panel Features

The JBOD storage enclosure has a front control panel (1), slots for up to 24 drives (2) and plastic
end caps as shown in (3) to cover the front-mounting hardware.

Figure 1-4 IS2224 JBOD Storage Enclosure Example (Front View)

The front-panel control LEDs (see callout (1) in Figure 1-4 and also Figure 1-5 on page 5) provide
status and operational information for the JBOD enclosure. Note that during the power-up process
these LEDs may flash intermittently until all sub-systems within the enclosure are fully powered
on. Ensure that all storage enclosures in the system have powered on fully before bringing the
system server online. The indicators have the following functions:

(1) Storage enclosure identifier LED - this blue/white indicator is on for unit identification only
(2) Amber service action required LED
(3) Amber over temperature warning LED
(4) Green “power good” LED lights when the enclosure is fully operational
(5) Green “standby” power mode LED lights when power is available (but unit is not operational)

Figure 1-5 IS2224 JBOD Enclosure Front Status Panel Example

Retention of critical data is enabled by optional, fully redundant and hot-swappable
Environmental Services Modules (ESMs). Each ESM features three 6Gb/s SAS ports, providing
connectivity for two host devices and an expansion port to connect additional JBOD enclosures
via SFF-8088 connections. LEDs on the power supplies, ESMs and each individual drive carrier
allow all system components to be closely monitored to help system administrators ensure storage
integrity. Figure 1-4 on page 4 shows an example rear view of the IS2224 JBOD enclosure.

All system power, data interconnect and some status LEDs are located on the back of the system.

description of the problem to [e-mail]

. A coordinator will contact you about the problem.

Prepare for Setup

Read the Warnings and Precautions 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.

Warnings and Precautions

Warning: When lifting any of the NAS enclosures, two people (one at each end) should lift

slowly with feet spread apart to distribute the weight. Always fo llow safe lifting practices
when moving heavy objects, failure to do so may result in serious i njury. More informatio n
on moving large objects, requiring a two-person team, is available in the Centers for Disease
Control’s, “Ergonomic Guidelines for Manual Material Handling”

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

• Use 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 drives and power supply modules to cool before touching them.

Rack Mounting Considerations

Use the guidelines in the following subsections when rack mounting servers or JBOD expansion
units.

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).

Reduced Airflow

Equipment should be mounted into a rack so that the amount of airflow required for safe operation
is not compromised. Always keep the rack’s front door and all panels and components on the
systems closed when not servicing to maintain proper cooling.

Mechanical Loading

Equipment should be mounted into a rack so that a hazardous condition does not arise due to
uneven mechanical loading.

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 nameplat e ratings should be used
when addressing this concern.

Installing the ISS3124-RP2 NAS Server into a Rack

007-5922-001 13

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).

Installing the ISS3124-RP2 NAS Server into a Rack

Use the following steps to install the ISS3124-RP2 NAS server rail kit in the rack.

4. System Safety

This chapter describes basic safety precautions for working with the SGI ISS3124-RP2 NAS
systems.

Electrical Safety Precautions

Basic electrical safety precautions should be followed to protect yourself from harm and the
Modular InfiniteStorage system from damage, as follows:

• Be aware of the locations of the power on/off buttons 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 power supplies 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 all power supply cords before
servicing to avoid electrical shoc k .

• 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).

42 007-5922-001

4: System Safety

NAS Node Serverboard Battery

Caution: There is a danger of explosion if an onboard battery is installed upside down, which
will reverse its polarities (see 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. Dispose of used batteries according to the
manufacturer's instructions.

Figure 4-1 Installing the Onboard Battery

Mainboard Replaceable Soldered-in Fuses

Important: If your system comes with self-resetting PTC (Positive Temperature Coefficient)
fuses on the NAS head node 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 system clean and free of clutter.

• 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.

Battery holder

ESD Precautions

007-5922-001 43

• 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 in the rack

unit after ensuring that all connections have been made.

ESD Precautions

Caution: Electrostatic discharge (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.

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 antist atic 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 head node serverboard and peripherals back into their antistatic 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.

• Detecting Component Failures

• No Video

• Loss of System Setup Configuration

• Safe Power-Off

• Checking System Air Flow

Note: Some software products are protected with software license keys derived from the
Media Access Control (MAC) Ethernet address. If your system requires the replacement of a
NAS controller head (node) board, the MAC Ethernet address changes. If you are using such
a product, you must request a new license key after replacement of the SGI NAS server node
board. Contact your local customer support office:

http://www.sgi.com/support/supportcenters.html

Caution: Always re-install the chassis cover after you have accessed any internal components to
ensure proper airflow and cooling for the system. Failure to re-install the cover may cause thermal
over-temperature conditions and automatic shut-down of the system.

5: Troubleshooting Information

Handling NAS Internal Components

Caution: Electrostatic discharge (ESD) can damage electrostatic-sensitive devices inside the
NAS enclosure. Use the ESD precautions described below when you handle printed circuit boards
or other components in the system. The following measures are generally sufficient:

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

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

• Handle each printed circuit board (PCB) by the edges; do not touch the components,
peripheral chips, memory modules, or gold contacts on the PCB.

• When handling any device with exposed chips or modules, avoid touching the pins.

• Place the NAS head node board, drives, or other boards and components into antistatic bags
when not in use.

• Make sure your system chassis provides a conductive path between the power supply, the
case, the mounting fasteners, and the node board to chassis ground.

Detecting Component Failures

Use the information in the following subsections to determine if any errors are occurring in the
drives or system power supplies.

ISS3124-RP2 Server Power Supply LEDs

There is a single bi-color LED (green/amber) to indicate the ISS3124-RP2 server power supply
status. Table 5-3 describes the different states of the LED.

No Video After Power-On

If the power is on and the system has had adequate time to boot, but there is no video, check all
add-on cards and cables. Tighten or re-plug any loose cable connections. Be sure your monitor is
powered up and switched to the

On position.

Use the speaker to determine if any beep codes exist. Refer to Appendix A, “BIOS Error Codes”
for details.

If video output is still absent, check with your system administrator or service provider.

Loss of System Setup Configuration

Make sure that your power supplies are operating properly, see “No Video After Power-On” on

page 48 for guidelines. An improperly operating power supply may cause the system to lose the

CMOS setup information. If this does not fix the Setup Configuration problem, consult your
system administrator or contact your service organization for repairs.

AC cord unplugged or AC power lost. A second power supply in parallel
still has AC input power.

Amber, 1Hz blink PS warning events where the power supply continues to operate (high

temperature, high power, high current, slow fan).

Safe Power-Off

There are several safe power-off methods for an SGI NAS Server or JBOD. They include,

• Using the OS GUI power-off button at the console screen, if a keyboard/mouse/video
monitor is connected.

• Pushing and holding the Power button on the front panel (see “Front Bezel and Control

Panels” in Chapter 3).

• When logged in via an ssh session and executing a “shutdown” or “poweroff”
command.

• When logged in to the BMC and using the power control page to power off the sever.

• Using the remote console screen GUI power-off button, if a KVM RMM4Lite session is
established through the BMC.

For an IS2224 NAS JBOD Unit, the power button on the front panel will turn off the power to that
I/O module. If an additional JBOD module is installed and powered on, it, the fans and the drives
will remain on until it, too, is powered off.

Checking System Airflow

Ensure that rack internal cabling is not blocking the front or rear airflow through the NAS server
or JBOD units. Reduced airflow may cause an over-temperature (overtemp) condition in the NAS
server or JBOD enclosures.

Important: Failing to keep the enclosure cover(s) in place during operation may cause airflow
interruption to critical internal components and consequent overheating and shutdown.

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.

Appendix A

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.

The BMC may generate beep codes upon detection of failure conditions that do not allow the
system to fully boot. Beep codes are sounded each time the problem is discovered (for example,
on each power-up attempt) but are not sounded continuously. Common supported codes are listed
in Table A-1.

In Table A-1, each digit in the code is represented by a sequence of beeps whose count is equal to
the digit.
