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 con-
nected 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 proces-
sor and memory).
SAS
The LSISAS2x36 is a x36 expander that provides SAS 2.0 support. RAID 0, 1, 10
and 1E modes. Refer to the following ftp site for setup guidelines: <ftp://ftp.super-
micro.com/driver/SAS/LSI/LSI_SAS_EmbMRAID_SWUG.pdf> and Supermicro's
web site for additional inmformation < http://www.supermicro.com/support/manu-
als/> (RAID is supported by third-party software.)
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,

1-3
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 airflow.
1-4 SBB: Storage Bridge Bay
The 937R-E2JB Super SBB was designed to function as a fully redundant, fault-
tolerant "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 configuration.
The Super SBB provides hot-swappable trays for the BMB-937-JB expanders.
Equipped with 700W (Gold Level) high-efficiency redundant power supplies and
redundant cooling fans, the 937R-E2JB is a high-available, high-reliability JBOD
storage system at a competitive price.

Chapter 2
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 file 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 fields are generated. You will also
need it placed near a grounded power outlet. Read the Rack and Server Precau-
tions in the next section.
2-3 Preparing for Setup
The box the SBB 937R-E2JB was shipped in should include two sets of rail assem-
blies, 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 sufficient airflow and ease in servicing.
This product is for installation only in a Restricted Access Location (dedicated
•
equipment rooms, service closets and the like).

Warnings and Precautions!
Rack Precautions
Ensure that the leveling jacks on the bottom of the rack are fully extended to•
the floor 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 first, 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.

Chapter 2: Server Installation
2-3
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating tempera-
ture 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 tempera-
ture (Tmra).
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.
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 connec-
tions other than the direct connections to the branch circuit (i.e. the use of power
strips, etc.).

2-6 Checking the Drive Bay Setup
Next, you should check to make sure the peripheral drives and the SAS drives have
been properly installed and all connections have been made.
Checking the Drives
The hard drives can be installed and removed from the front of the chassis1. without removing the top chassis cover.
Depending upon your system's configuration, your system may have one or2. more drives already installed. If you need to install hard drives, please refer to
Chapter 5.
Checking the Airflow
Airflow is provided by 4-cm counter-rotating fans. The system component1. layout was carefully designed to direct sufficient cooling airflow to the compo-
nents that generate the most heat. See Chapter 5 for details.
Note that all power and data cables have been routed in such a way that they2. do not block the airflow generated by the fans.
Providing Power
Plug the power cord(s) from the power supply unit(s) into a high-quality power1. strip that offers protection from electrical noise and power surges. It is recom-
mended that you use an uninterruptible power supply (UPS).
Depress the power on button on the front of the chassis.2.
