This drive is in conformity with the EMC directive.
Federal Communications Commission (FCC)
Statement
This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC Rules.
Those limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of
the following measures:
Reorient or relocate the receiving antennas.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circlet different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
Warning:
A shielded-type power cord is required in order to meet FCC emission limits and
also to prevent interference to the nearby radio and television reception. It is
essential that only the supplied power cord be used.
Use only shielded cables to connect I/O devices to this equipment.
You are cautioned that changes or modifications not expressly approved by the
party responsible for compliance could void your authority to operate the

The Alnico RAID series includes 16 hot swappable drive bays. The following
sections describe how to install disks into Alnico RAID subsystems.
Loading Hard Disk to the drive bay.
1. Put HDD into the bay.
2. Fasten all 4 screws to mount HDD in
the bay and make sure the HDD is
properly tightened.
Place drive bays back into the system
1. Slide in drive bay, make sure the
handle is open fully.
2. Close the handle to engage the drive
bay into the slot.
The hard drives in a RAID array should match in size and speed. All drives in
any array should be identical models with the same firmware versions. RAID
arrays can use any size drive, however the smallest drive will determine the
size of the array.
12
1.
Only use the screws offered with Alnico RAID subsystem. Longer screws
might cause the drive damage.
2.
All the drive bays ( with or without hard drive) must be placed in the
Alnico subsystem. Alnico’s cooling system is designed with full of drive
bays. Missing drive bays might cause the subsystem damage.

to rackmount. Alnico subsystem is designed for installation into a
industry-standard 19-inch rackmount cabinet. Following the use of this section
for installing the Alnico subsystem into a Rack
Install the Slide Rails
1. Combine Left slide rail and rear slide rail.
2. Measure the depth of the rack enclosure, then fasten 4 of P4*8M screws
into M4 Locking nuts to fix the length.
3. Use T5*8M screws and PW14 washer to install the left slide on Front and
rear Posts of Rack as Figure 1.
4. repeat procedure 1 ~ 3 to install the right Slide into the Rack.
Figure 1.
Place the Alnico Subsystem into the rack
1. Lift the subsystem enclosure and slide it slowly and gently along the slide rail

First tier is a RAID System.

Second tier is a SAS JBOD with a SAS CH0 on it. Connecting SAS CH0 to SAS
exp. Port on RAID System via a Mini SAS to Mini SAS Cable.

Third tier could be two SAS JBODs with a SAS CH0 port individually. One is
connected to the SAS EXP. Port on the second tier SAS JBOD via a Mini SAS to
Mini SAS Cable. Another is connected to the SAS CH1/E Port on the second tier
SAS JBOD

Fourth tier is a SAS JBOD with a SAS CH0 on it. Connecting SAS CH0 to SAS exp.

1.
Alnico RAID subsystem do not require the installation of different
drivers for use with different operating systems. Alnico RAID is
independent and transparent to the host operating system.
2.
It is often recommended to install the hard drive with same brand, model
no., interface and capacity in this RAID subsystem.
3.
Please do not install SAS and SATA hard drives at the same time, as
these hard drives spin at different speed and may lead to compatible
issues or performance decline.
4.
RAID members need to be included at the same enclosure that means
you need to create array in the same enclosure. RAID members across
two or more enclosures would get some risks (for example: if mini-SAS
cable get problem, more RAID members will be lost, volume sets belong
to this Array may be failed. Shutdown RAID and JBOD to fix problem,
after that, turn on JBOD and RAID system again and controller will get
array back, but in some special case maybe it can’t get array back)

When cabling is completed, RAID SYSTEM can be turned on. This should be
done in the following order:
1. First turn on the power switch of JBODs.
2. Then turn on the power switch of RAID SYSTEM.
3. Power on and boot the host computer(s)
17
Hardware Installation Guide
When RAID SYSTEM is running, you are ready to configure one or more RAID
arrays. You have the following options:
1. Turn to Chapter 3 of “Software Operation Manual” to perform a quick setup of
a single RAID array using the control panel.
2. Turn to Chapter 6 of “Software Operation Manual” to access the Monitor
Utility. Once the Monitor Utility is accessed, you can perform a Quick Setup
or complete configuration with Monitor Utility.
3. Turn to Chapter 5 of “Software Operation Manual” to perform a full
configuration using the web browser.

Alnico RAID are normally supplied with 512MB cache memory installed.
There's no set formula to determine how much cache memory to use, but as a
general rule, a workstation, with mostly very large files, such as for audio or
video editing and playback, graphics or CAD files, can benefit from a large
cache. File servers, with multiple random access of varying file size,
generally have little or no performance improvement with additional cache.

Chapter 3. Trouble Shooting
Installing DIMM
To install a DIMM, ensure the system power is off and disconnected. Then:
1. Turn anti- lock wise to release two thumb
screws, then use the eject bar to remove
controller box, then open the cover.
2. Remove the BBM module.
3. Insert a memory card at a 45-degree angle
into the memory card socket so that the
gold teeth of the card are no longer visible.
4. Press the card down firmly until the latches
lock it into place.
1.
Before starting any kind of hardware installation, please ensure that all
power switches have been turned off and all power cords disconnected to
prevent personal injury and damage to the hardware.
2.
Use screws provided with Alnico system only. Longer or shorter screws
may cause electric shorting or un-proper installed.
3.
Static electricity can damage electronic components. To guard against such
damage:
Work in a static-free environment
Wear a grounded anti-static wrist strap
Store uninstalled components in anti-static bags
Handle PCBs by their edges and avoid touching chips and connectors.

Battery Backup Module (BBM)
The external RAID controller operates using cache memory .The battery Backup
Module is an add-on module that provides power to the external RAID controller
cache memory in the event of a power failure. The Battery Backup Module
monitors the write back cache on the external RAID controller, and provides power
to the cache memory if it contains data not yet written to the hard drives when
power failure occurs.

z
Install the BBM and fasten 4 screws.
Plug in the BBM’s connector into J6 of Controller.
Battery Backup Capacity
Battery backup capacity is defined as the maximum duration of a power failure for
which data in the cache memory can be maintained by the battery. The BBM’s
backup capacity varied with the memory chips that installed on the external RAID
controlle

z
Battery conditioning is automatic. There are no manual procedures for
battery conditioning or preconditioning to be performed by the user.
z
Battery bad a tendency to “remember” its capacity. In order to make sure of
all the capacity of your battery cells, allow the battery cell to be fully charged
when installed for the first time. The first time charge of battery cells takes
about 24 hours to complete.
Removing the Battery Backup Module
The battery module will need to be removed for one of the following reason:
z
Disconnect battery module if there is a long storage period before
deployment
z
The LI-ION battery will no longer accept a charge properly.
