SBB 937R-E2JB User's Manual

1-2 SAS Expander

The SBB 937R-E2JB includes two BMB-937-JB expanders, which are mounted on
hot-swappable trays. The BMB-937-JB utilizes the LSISAS2x36, which is a 36-port,
6 Gb/s SAS expander.

Cascading

Each BMB-937-JB has a SAS-IN port and a SAS-OUT port, which in turn are con­nected to an I-SAS port at the rear of the chassis. The I-SAS port may then be
used to cascade to another system (must be cascaded to a system with a proces­sor and memory).

SAS

The LSISAS2x36 is a x36 expander that provides SAS 2.0 support. RA ID 0, 1, 10
and 1E modes. Refe r to t h e fo ll ow i ng ftp site for setup gui de li n es: < ftp://ftp.sup er­micro.com/driver/SAS/LSI/LSI_ SAS_EmbMR AID_SWUG.pdf> and Supermicro's

1-3 Server Chassis Features

System Power

The SC937 features a redundant Gold Level 700W power supply composed of two
separate power modules. This power redundancy feature allows you to replace a
failed power module without shutting down the system.

SAS/SATA Subsystem

The SC937 supports up to 16 3.5" SAS drives. These drives are hot-swappable
units and are connected to a midplane that provides power and control.

Notes: The operating system connected to the SBB system must have RAID support
to enable the hot-swap capability of the SAS drives. As an alternative to SAS drives,

3.5" SATA drives can be supported via an interposer (AOL-LSISS9252).

Front Control Panel

Two control panels are included on each end of the SBB 937R-E2JB to provide you
with system monitoring and control. LEDs indicate system power, cascade status,

1-2

Chapter 1: Introduction

system overheat and power supply failure. Each set of LEDs are associated with the
node/serverboard on the same side of the chassis. A single power button is located
on the right side control panel. When pressed, both nodes will power on or off.

Cooling System

The SC937 chassis has six fans at the front of each expander, which consists of
three sets of two 4-cm counter-rotating fans. This counter-rotating action works to
dampen vibration levels while generating exceptional airfl ow.

1-4 SBB: Storage Bridge Bay

The 937R-E2JB Super SBB was designed to function as a fully redundant, fault­tolerant "cluster-in-a-box" JBOD system. The support for 16 3.5" hot-swap HDDs has
been expanded to support cascading with the SBB JBOD 937R-E2JB confi guration.
The Super SBB provides hot-swappable trays for the BMB-937-JB expanders.

Equipped with 700W (Gold Level) high-effi ciency redundant power supplies and
redundant cooling fans, the 937R-E2JB is a high-available, high-reliability JBOD
storage system at a competitive price.

Server Installation

2-1 Overview

This chapter provides a quick setup checklist to get your SBB 937R-E2JB up and
running. Following these steps in the order given should enable you to have the
system operational within a minimum amount of time.

2-2 Unpacking the System

You should inspect the box the SBB 937R-E2JB was shipped in and note if it was
damaged in any way. If the server itself shows damage you should fi le a damage
claim with the carrier who delivered it.

Decide on a suitable location for the rack unit that will hold the SBB 937R-E2JB.
It should be situated in a clean, dust-free area that is well ventilated. Avoid areas
where heat, electrical noise and electromagnetic fi elds are generated. You will also
need it placed near a grounded power outlet. Read the Rack and Server Precau­tions in the next section.

2-3 Preparing for Setup

The box the SBB 937R-E2JB was shipped in should include two sets of rail assem­blies, two rail mounting brackets and the mounting screws you will need to install the
system into the rack. Follow the steps in the order given to complete the installation
process in a minimum amount of time. Please read this section in its entirety before
you begin the installation procedure outlined in the sections that follow.

Choosing 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 suffi cient airfl ow and ease in servicing.

This product is for installation only in a Restricted Access Location (dedicated

•

equipment rooms, service closets and the like).

This product is not suitable for use with visual display work place devices •
acccording to §2 of the the German Ordinance for Work with Visual Display
Units.

Warnings and Precautions!

Rack Precautions

Ensure that the leveling jacks on the bottom of the rack are fully extended to •
the fl oor with the full weight of the rack resting on them.

In single rack installation, stabilizers should be attached to the rack. In multiple

•

rack installations, the racks should be coupled together.

Always make sure the rack is stable before extending a component from the

•

rack.

You should extend only one component at a time - extending two or more si-

•

multaneously may cause the rack to become unstable.

Server Precautions

Review the electrical and general safety precautions in Chapter 4.•

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

Install the heaviest server components on the bottom of the rack fi rst, and then

•

work up.

Use a regulating uninterruptible power supply (UPS) to protect the server from

•

power surges, voltage spikes and to keep your system operating in case of a
power failure.

Allow any hot plug drives and power supply modules to cool before touching

•

them.

Always keep the rack's front door and all panels and components on the servers

•

closed when not servicing to maintain proper cooling.

2-2

Chapter 2: Server Installation

Rack Mounting Considerations

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 (Tmra).

Reduced Airfl ow

Equipment should be mounted into a rack so that the amount of airfl ow 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.

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 overcurrent 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 (i.e. the use of power
strips, etc.).

The single button located on the right control panel is the power on/off button.
Depressing this button will either power both nodes on or off.Turning off system
power with this button removes the main power but keeps standby power supplied
to the system.

3-3 Control Panel LEDs

The two control panels located on the front of the chassis have several LEDs. With
the exception of the power fail LED, these LEDs provide you with critical information
related to the node on the same side of the chassis. This section explains what each
LED indicates when illuminated and any corrective action you may need to take.

Power Fail

Indicates a power supply module has failed. The second power supply module will
take the load and keep the system running but the failed module will need to be
replaced. Refer to Chapter 5 for details on replacing the power supply. This LED
should be off when the system is operating normally.

3-1

SBB 937R-E2JB User's Manual

Overheat/Fan Fail:

When this LED fl ashes, it indicates a fan failure. When on continuously it indicates
an overheat condition, which may be caused by cables obstructing the airfl ow in
the system or the ambient room temperature being too warm. Check the routing of
the cables and make sure all fans are present and operating normally. You should
also check to make sure that the chassis covers are installed. Finally, verify that
the heatsinks are installed properly (see Chapter 5). This LED will remain fl ashing
or on as long as the indicated condition exists.

Chapter 4

System Safety

4-1 Electrical Safety Precautions

Basic electrical safety precautions should be followed to protect yourself from harm
and the SBB 937R-E2JB from damage:

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. When disconnecting power, you should
fi rst power down the system with the operating system. The unit has more than
one power supply cord. Disconnect both 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 specifi cally
designed as electrical insulators.

The power supply power cords must include a grounding plug and must be

•

plugged into grounded electrical outlets.

4-1

SBB 937R-E2JB User's Manual

!

This product may be connected to an IT power system. In all cases, make sure •
that the unit is also reliably connected to Earth (ground).

DVD-ROM Laser:

• CAUTION - this server may have come equipped with a

DVD-ROM drive. To prevent direct exposure to the laser beam and hazardous
radiation exposure, do not open the enclosure or use the unit in any uncon­ventional way.

4-2 General Safety Precautions

Follow these rules to ensure general safety:

Keep the area around the 937R-E2JB clean and free of clutter.

•

The 937R-E2JB weighs approximately 75 lbs (34 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.

Place the chassis top cover and any system components that have been re-

•

moved 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.

4-2

Chapter 4: System Safety

!

4-3 ESD Precautions

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 com ponents and printed
circuit boards. The following measures are generally suffi cient 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 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.

5-3 System Fans

System cooling is provided by three sets of counter-rotating fans at the front of
each expander. Each fan assembly (one for each node) consists of three sets of
counter-rotating fans. The counter-rotating action helps dampen vibration levels
while generating exceptional airfl ow.

It is very important that the chassis cover is properly installed and making a good
seal 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 an expander. If a fan fails, the
remaining fans will ramp up to full speed and the overheat/fan fail LED on the
control panel (of the same side as the failed fan) will turn on. The counter-rotating
fans may also be visually inspected for failure. Replace any failed fan at your earli­est convenience with the same type and model (the system can continue to run
with a failed fan). Remove the top chassis cover while the system is still running to
determine which of the fans has failed.

Replacing System Fans

Replace the failed fan with an identical 4-cm, 12-volt counter-rotating fan (p/n FAN­0088L4, available from Supermicro). See Figures 5-2 and 5-3.

Replacing Fans

Shutdown the node with the failed fan(s) and remove the AC power cord.1.

On the node with the failed fan, push the release bar down to unlock the 2.
serverboard tray.

Use the bar to pull the node/serverboard from the chassis.3.

Remove the failed fan from the assembly and replace it with an identical 4.
replacement. You may need to remove the assembly to replace the lower fan.

Slide the serverboard tray back into the chassis. When seated, lift the release 5.
bar to lock it into place.

Reconnect the AC power cord and power up the node.6.

Inspect the replaced fan to verify it is working.7.

5-4 Drive Bay Installation/Removal

Accessing the Drive Bays

SAS Drives: You do not need to access the inside of the chassis or remove power
to replace or swap SAS drives. Proceed to the next step for instructions. You must
use standard 3.5" SAS drives in the system.

Note: Refer to the following ftp site for setup guidelines: <ftp://ftp.supermicro.com/
driver/SAS/LSI/LSI_SAS_EmbMRAID_SWUG.pdf> and Supermicro's web site for
additional inmformation < http://www.supermicro.com/support/manuals/>.

Hard Drive Midplane

The hard drives plug into a midplane that provides power, drive ID and bus termi­nation. A RAID controller can be used with the midplane to provide data security.
The operating system you use must have RAID support to enable the hot-swap
capability of the hard drives. The midplane is already preconfi gured, so no jumper
or switch confi gurations are required.

SAS Drive Installation

These drives are mounted in drive carriers to simplify their installation and removal
from the chassis. The carriers also help promote proper airfl ow for the drives. For
this reason, even empty carriers without hard drives installed must remain in the
chassis.

Removing a HDD Carrier from the Chassis (Figure 5-4)

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

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

Installing a SAS Hard Drive (Figures 5-5 and 5-6)

Remove the screws securing the dummy drive to the drive carrier.1.

Remove the dummy drive. Place the carrier on a fl at surface.2.

Slide the hard drive into the carrier with the printed circuit board side down.3.

Carefully align the mounting holes in both the drive tray and the hard drive.4.

Enterprise level hard disk drives are recommended for use in Supermicro
chassis and servers. For information on recommended HDDs, visit the
Supermicro Web site at http://www.supermicro.com/products/nfo/fi les/
storage/SAS-1-CompList-110909.pdf

Use caution when working around the midplane. Do not touch the midplane
with any metal objects and make sure no cables touch the midplane or
obstruct the holes, which aid in proper airfl ow.

Important: Regardless of how many hard drives are installed, all drive car­riers must remain in the drive bays to maintain proper airfl ow.

5-6 Power Supply

The SBB 937R-E2JB has a 700 watt redundant power supply consisting of two
separate 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.

When fully inserted into the chassis, the power supplies connect automatically to a
power distribution board (PDB). The PDB in turn connects to the midplane via two
black power connectors as shown in Figure 5-7.

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. Replace­ment units can be ordered directly from Supermicro. The power supply units have
a hot-swap capability, meaning you can replace the failed unit without powering
down the system.

Replacing the Power Supply

You do not need to shut down the system to replace a power supply unit. The
backup power supply module will keep the system up and running while you replace
the failed hot-swap unit. Replace with the same model (see part number in the Ap­pendix), which can be ordered directly from Supermicro.

Replacing the Power Supply

The SC937 chassis includes a redundant power supply (at least two power 1.
modules), you can leave the server running if you remove only one power
supply at a time.

Unplug the power supply that you will replace.2.

Push the release tab (on the back of the power supply) as illustrated.3.

Pull the power supply out using the handle provided.4.

Replace the failed power module with the same model.5.

Push the new power supply module into the power bay until you hear a click. 6.

Plug the AC power cord back into the module and power up the server.7.
