Safety Precautions
Read these instructions carefully before you install, operate, or transportthe PS 2000 Series
Unified Storage system and JBODs.
Energy Hazards Precaution
This equipment is intended to be used in Restrict Access Location, like computer room.
The access can only be gained by SERVICE PERSONS or by USERS who have been
instructed about the metal chassis of the equipment have energy hazards that service
persons have to pay special attention or take special protection before touching it. Further,
the access is through the use of key or security identity system. Only authorized by well
trained professional person can access the restrict access location.
Installation and Operation
Install the rack cabinet and the associated equipment at a site where the ambient
temperature (special room cooling equipment may be required) stays lower than:
a. 35 C ~ if your system has a BBU
b. 40 C ~ if your system does not have a BBU
Install the power source socket outlet near the enclosure where it is easily
accessible and ground the rack cabinet.
Secure airflow clearance inside and around the rack cabinet.
- Secure an 18 to 20cm clearance on the rear side.
- Do not cover the enclosure openings.
- Route the cables inside the rack cabinet.
- Do not leave drive bays empty as it will affect airflow efficiency.
Secure each enclosure module using its retaining screws.
Place power cords and other cables away from foot traffic. Do not place items
on top of power cords and make sure they do not rest against data cables.
Install all modules to the enclosure before powering-on systems.
Ensure that the correct power range is being used before powering-on.
DO NOT remove covers or replaceable modules if they are not faulty.
If the system is not going to be used for a long period of time, disconnect it from
the power mains to avoid transient over-voltage.
For power source redundancy, please make sure that the two PSUs are plugged
into two different power sources (i.e. Different circuit breakers).
Service and Maintenance
Keep the faulty module in place until you have a replacement unit; an empty
module greatly affects the airflow efficiency within the enclosure.
During service operation, place the enclosure on soft and clean surface to
prevent exterior damage. Do not place tools or other items on top.
When transporting the enclosure, repackage all disk drives separately in the
original package foam blocks. Replaceable modules can stay in the enclosure if
you are using the original package; if not, repackage them separately as well.

7
Disconnect the power cords before servicing or cleaning the enclosure.
Use a slightly moistened paper sheet or cloth for cleaning. Avoid using liquid or
sprayed detergent.
When replacing components, insert them as gently as possible while assuring
full engagement. Vibration and shock can easily damage hard drives.
Only qualified service personnel should open the enclosure.
Contact service personnel if any of the following situations occurs:
- The power cord or plug is damaged.
- The enclosure has been exposed to moisture.
- The system has not been working properly.
- The enclosure was dropped against a hard surface.
- The enclosure shows obvious signs of breakage.
To move the enclosure, more than one person might be necessary due to its weight.
Drives should be removed from the enclosure beforehand.
Important Notice
The use of PAC Storage certified components is strongly recommended to ensure
compatibility, quality and normal operation with your PAC Storage products. Please contact
your distributor for a list of PAC Storage certified components (e.g. SFP, SFP+, HBAcard,
iSCSI cable, FC cable, memorymodule, etc.).
ESD Precautions
Handle the modules by their retention screws, ejector levers, or the module’s
metal frame/faceplate only. Avoid touching the PCB boards or connector pins.
Use a grounded wrist strap and an anti-static work pad to discharge static
electricity when installing or operating the enclosure.
Avoid dust, debris, carpets, plastic, vinyl, and Styrofoam in your work area.
Do not remove any module or component from its anti-static bag before
installation takes place.
Drives must not be stacked on top of each other without their protective drive
trays. Even when drives are fixed in the drive trays, contacting the exposed PCB
or rear-side interface may damage the drives.

Major Components
NOTE
Upon receiving your system, check the package contents against the included
Unpacking List. If module(s) are missing, please contact your system vendor
immediately.
Controller and Interface
Each controller comes with pre-installed DIMM module(s).
The traditional battery backup is replaced by an innovative Cache Backup Module
methodology (CBM) which consists of a super capacitor and a flash backup module (FBM).
Cached data is quickly distributed to a flash backup module for permanent storage with the
support of the super capacitor in the event of a power outage. The advantage of a super
capacitor is its very fast charging time. The super capacitor is charged within a few minutes
and available to distribute power to the controller. So cached data can be saved
immediately and permanently in flash backup module (FBM).
The embedded firmware features intelligent algorithms, such as power-saving modes,
variable fan speeds, and exiled drive handling, making this model a greener choice.

10
JBOD Controller and Interface
The enclosure is managed by expander controllers that distribute data flow to individual disk
drives and report operating status through a proprietary enclosure service via in-band
protocols. The enclosure, along with other JBODs, connects to a Unified Storage system and
serves as a building block of a scalable configuration.
In terms of supported protocols, the firmware supports communications with enclosure
devices, SAS/SATA disk drives and as Unified Storage system featuring SAS expansion
ports.
In terms of physical connection, the SAS interface provides ease of cabling through Mini-
SAS connectors. With a backplane adapting SAS or SATA drives, the system supports
enterprise-class SAS, Near-line SAS, cost-effective SATA-II or SATA-III hard drives or
SSDs, and is ideal for adding large capacity to a storage pool.
Power supply unit with built-in cooling module
Cooling module is built into the power supply unit (PSU) to protect the system from
overheating. The two hot-swappable PSUs provide constant power to the system. The
modular nature of the system and the easy accessibility to all major components ensure ease
of maintenance.
The Rear Panel
Dual Controller Models
Controller A is located on top and controller B at the bottom for all models. If one controller
fails, the second controller module will take over in a manner that is transparent to
application servers.
2U
models
3U
models
The top controller (Controller A) is the primary controller. The bottom controller (Controller
B) is the secondary (= redundant) controller which is idle during normal operation and takes
over the management role when Controller A cannot function properly due to hardware
error, controller module removal, etc.
If the failed Controller A restarts or a replacement is installed, Controller A will temporarily
assume the role of the secondary controller.
When the Unified Storage system is rebooted, all system configurations will revert back to
the default state and Controller B returns the primary role to ControllerA.

Supercapacitor & Flash Module
The super capacitor (1) and flash backup module (2) can be located inside the controller and serves
as a Cache Backup Module (CBM). With the super capacitor, the cached data can be stored
permanently in the flash backup module, in case of a power outage.
NOTE
The supercapacitor is only charged partially when shipped. Therefore, after powering
on the system, the supercapacitor will start charging to its full capacity. The
supercapacitor will be charged within a few minutes. If the supercapacitor is not
charged, there may be a problem with the supercapacitor and you should contact
your system vendor immediately. You can also check the status of the
supercapacitor module via the PAC Management Software or the firmware (please
refer to respective manuals).
PSU & Cooling Module
The two redundant, hot-swappable PSUs have a power socket (1), power switch (2), PSU
status LED (3), cooling module (4), retentionscrew (5) and an extraction handle (6).

18
The cooling modules can operate at three rotation speed settings. Under normal
operating conditions, the cooling fans run at the low speed. Under the following conditions,
cooling fans raise their rotation speed to increase the airflow:
•Component failure: if a cooling module, PSU, or a temperature sensor fails.
•Elevated temperature: if the temperature breaches the upper threshold set for any of the
interior temperature sensors.
•During the system initialization stage, the cooling fans operate at high speed and return to
low speed once the initialization process has completed and no erroneous condition detected.
NOTE
There are two upper temperature thresholds: one for event notification and the other
for triggering higher fan rotation speed. The preset-value for event notification can be
changed using the firmware-embedded configuration utility, while the fan speed
trigger cannot be changed. Refer to the Firmware Operation Manual for details.
System Monitoring Features
There are a number of monitoring approaches that provide the operating status of individual
components.
Expansion Enclosure Support
Monitoring:
A managing Unified Storage System is aware of the status of JBOD components including
those of:
•Expander controller (presence, voltage and thermal readings)
•PSU
•Cooling module
•Enclosure thermal sensor
•Service (the Service signal to specify a specific enclosure)
•Disk drives
JBOD Identifier:
The managing Unified Storage System will sound the alarm and deliver warning messages if
there is a conflict between JBOD IDs.
If more than one JBOD is connected to the managing Unified Storage System, each JBOD
needs a unique enclosure ID set using the rotary switch on the LED panel. For example, the
firmware automatically disconnects the second JBOD if it is connected online and comes
with an ID identical to that of the first JBOD.
NOTE
The IDs for JBODs are #1 to #15. For details, please refer to JBOD connections.
Cooling Module Speed Adjustment:
If any of the detected temperature readings breaches the temperature threshold, the
firmware running on the managing Unified Storage System automatically raises the rotation
speed of all cooling fans.

19
JBOD Enclosure Status Monitoring
A Unified Storage system, when connected with expansion JBODs, acquires the component
status within other enclosures via a proprietary enclosure monitoring service using the in-band
connectivity. No additional management connection is required.
I2C bus
The detection circuitry and temperature sensors are interfaced through a non-user-serviceable I2C
bus. When JBODs are attached to controllers, JBOD component status is reported through in-band
protocols over expansion links that is managed by a proprietary enclosure service.
Firmware (FW) and PAC Management Software
The firmware (FW) is preloaded and is used to configure the system. The FW can be
accessed through the PAC Management Software, a browser-based graphical user interface
(GUI) software that can be installed on a local/remote computer and accessed via the
network. The manager communicates with the array via the connection of the existing host
links or the Ethernet link to the array’s Ethernet port.
Audible Alarms
The system comes with audible alarms that are triggered when certain active components
fail or when certain controller or system thresholds are exceeded. Whenever you hear an
audible alarm, it is imperative that you determine the cause and rectify the problem
immediately.
Event notification messages indicate the completion or status of array configuration tasks
and are always accompaniedby two or three successiveand prolonged beeps. The alarm
can be turned off using the mute button on the front panel.
WARNING
Failing to respond when an audible alarm is heard can lead to permanent damage(s)
to the system. When an audible alarm is heard, rectify the problem as soon as
possible
System Monitoring
The system comes with a number of hot-swappable components that can be exchanged
while the system is still online without affecting the operational integrity. These components
should only be removed from the system when they have to be replaced.
The following components can be user-maintained and hot-swappable:
•Controller module (Dual Controller models)
•PSU (including cooling modules)
•Hard Drive
NOTE
Normalized airflow ensures sufficient cooling of the system and is only attained when
all components are properly installed. Therefore, a failed component should only be
removed when a replacement is available. For instructions on how to replace these
hot-swappable components, please refer to System Maintenance.

Hardware Installation
This chapter describes how to install modular components, such as hard drives into the
enclosure and CMB into Unified Storage controller enclosure.
NOTE
Installation into a rack or cabinet should occur BEFORE hard drives are installed into
the system.
Installation Prerequisites
Static-free installation environment: The system must be installed in a static-free
environment to minimize the possibility of electrostatic discharge (ESD) damage.
Component check: Before installing the system, check to see that you have received all
the required components using the Unpacking List included in the package. If there are
item(s) missing or appear damaged, contact your vendor for a replacement.
Hard drives: SAS/SATAhard drives must be purchased separately and be available prior to
installing the system.
Cabling: All the cables that connect the system to the hosts must be purchased
separately. Please refer to System Connection for sample topologies and configuration
options. Contact your vendor for the list of compatible cables.
Memory modules: If you wish to change the pre-installed DIMM module, you can find
DIMM replacement procedures in Replacing Memory Module(s).
Rack installation: The rack slide rails are optional accessories and should you need to install
it, please refer to the Slide Rail Installation Guide section.
Make sure you are aware of the related positions of each plug-in module and interface
connector.
Cables must be handled with care and must not be bent. To prevent emission interference
within a rack system and accidental cable disconnection, the routing paths must be
carefully planned.
Installation Procedures Overview
Following all the instructions provided below can minimize system installation time. Detailed,
illustrated instructions for each component are given in the following sections.
1. Unpack: Unpack the system and confirm all components have been received
against the Unpacking List.
2. Rack/Cabinet installation: If the system is going to be installed in a rack or
cabinet, it should be installed prior to installing the hard drives. Installing the
system into a rack or cabinet requires at least two people due to its weight.
3. Install CBM (if necessary): Install the CBM (Super Capacitor + Flash Backup
Module) onto the controller if you purchased it as an additional item.
4. Install hard drives: Separately purchased SAS/SATA hard drives must be
individually installed into the drive trays.
5. Install drive trays: After the hard drives have been installed into the drive trays, you
can install the drive trays into the enclosure (install trays AFTER the enclosure has
been mounted onto the rack).
