Chapter 1 Introduction
The Expansion Chassis
The JBOD subsystem is a 19-inch 4U rackmount JBOD unit. It features the latest
SASII (6Gb/s) interface and designed to fit in with the environments which needed
highly reliable and relentless data growth. The JBOD subsystem is also a versatile
SAS2/SATA3 disk expansion system, ideal for high capacity and scalability storage in
IT demands. Based on the 6G SAS technology, the JBOD subsystem supports the
choice of SAS2 and SATA3 drive configurations to deliver the best cost-performance
index with higher bandwidth.

1.5 Power Supply / Fan Module (PSFM)
The JBOD subsystem contains two 500W Power Supply / Fan Modules. All
PSFMs are inserted into the rear of the chassis.
1.5.1 PSFM Panel
The Power Supply/Fan Module panel has: Power On/Off Switch, the AC Inlet
Plug, and a Power On/Fail Indicator showing the Power Stat us LED, indicating
ready or fail.
Each fan within a PSFM is powered independently of the power supply within
the same PSFM. So if the power supply of a PSFM fails, the fan associated with
that PSFM will continue to operate and cool the enclosure.

1.5.2 Power Supply Module LED
When the power cord connected from main power source is inserted to the AC
Power Inlet, the power status LED becomes RED. When the switch of the PSFM
is turned on, the LED will turn GREEN. When the Power On/Fail LED is GREEN,
the PSFM is functioning normally.

1.7 Drive Carrier Module
The Drive Carrier Module houses a 3.5 inch hard disk drive. It is designed for
maximum airflow and incorporates a carrier locking mechanism to prevent
unauthorized access to the HDD.
1.7.1 Disk Drive Status Indicators
Every Drive Carrier has 2 status indicator lights. One indicat or light is used for
Power On/Error. When this light is GREEN the power is on and everything is
functioning normally. When the Power On/Error light is RED, then an error has
happened that requires the user’s attention.
The other status indicator light is the hard disk drive access light. When the
hard disk drive is being accessed, this light will flash BLUE.
In addition, both indicator lights are viewable within a 170° arc.

rate using SAS phy. Attach one end of the S AS cab le to th e SAS IN P or t and t he
other end to the host bus adapter’s (HBA) external SAS connector or to the SAS
Swit ch. (The ho st b u s adapter is installed in your Host computer system.)
2.3.2 Connecting to RAID Subsystem
Attach one end of the SAS cable to the SAS IN Port of the JBOD controller module
and the other end to the SAS Expansion Port on the RAID controller of RAID
subsystem. If configured in redundant mode, connect the other SAS cable to the
SAS IN Port of the other JBOD controller, and the other end to the SAS Expansion
Port on the other RAID controller of RAID subsystem.

Chapter 3 Maintenance
3.1 Upgrading the JBOD Controller’s Firmware
IMPORTANT: Before upgrade the JBOD firmware, please shut
down server first or make sure no array setting on the JBOD
disks. The new Firmware will effective after JBOD power cycle.
NOTE: Upgrading the firmware must be done from Master JBOD
Controller (JBOD Controller 1) if the JBOD Subsystem has
redundant JBOD Controllers.
Steps:
1. Please use the RS232 cable (Phone jack to DB9) to JBOD Controller #1 and to
connect JBOD RS232 Port and PC COM1 Port (or change to other COM Port as
necessary).
2. Open Windows HyperTerminal Program. Connect using COM1 (COM Port used in
Step1), Baud Rate: 115200, n, 8, 1, Flow Control: None.
3. Please type “system upgrade”, than press “Enter” in command line.

3.2 Replacing Subsystem Components
3.2.1 Replacing JBOD Controller Module
When replacing a failed JBOD Controller Module, please follow these steps:
1. Make sure the subsystem is in power off state. Loosen the thumbscrews on
the sides of the Controller Module case.
2. Use the Controller handle to pull out the defective Controller.
3. Insert and slide the new Controller in. Note that it may be necessary to
remove the old/defective Controller Module from the case and install the new
one.
4. Tighten the thumbscrews on the sides of the Controller Module case.

3.2.1.1 Replacing JBOD Controller Module with Blanking Plate
When replacing a failed Controller Module with Blanking Plate, please f ollow these
steps:
1. Loosen thumbscrews of the failed Controller Module.
2. Use the Controller Module handle to remove the failed Controller Module from
the subsystem.
3. Insert the Controller Blanking Plate included in your package.
4. Tighten the screws of the Blanking Plate.
When replacing a failed component online, it is not recommended to
remove the failed component for a long period of time; proper air
flow within the enclosure might fail causing high controller/disk
drive temperature.

User Manual
3.2.2 Replacing Power Supply Fan Module
When replacing a failed power supply fan module (PSFM), please fo llow these steps:
1. Turn off the Power On/Off Switch of the failed PSFM.
2. Disconnect the power cord from the AC Inlet Plug of PSFM.
3. Loosen thumbscrews of the PSFM.
4. Use the handle to pull out the defective PSFM.
5. Before inserting the new PSFM, make sure the Power On/Off Switch is on "Off"
state.
6. Insert and slide the new PSFM in until it clicks into place.
IMPORTANT: When the subsystem is online and a Power Supply
fails, and the replacement Power Supply module is not yet
available, the failed Power Supply Module can be replaced with
the Plate Cover. This is to maintain proper airflow within the
enclosure. (Refer to next section)
When replacing a failed component online, it is not
recommended to remove the failed component for a long period
of time; proper air flow within the enclosure might fail causing
high controller/disk drive temperature.
7. Connect the power cord to the AC Inlet Plug of PSFM.
8. Tighten the thumbscrews of the PSFM.
9. Turn on the Power On/Off Switch of the PSFM.
NOTE: After replacing the Power Supply Fan Module and turning
on the Power On/Off Switch of the PSFM, the Power Supply will
not power on immediately. The Fans in the PSFM will spin-up until
the RPM becomes stable. When Fan RPM is already stable, the
RAID controller will then power on the Power Supply. This
process takes more or less 30 seconds. This safety measure helps
prevent possible Power Supply overheating when the Fans cannot
work.
