14. General. This EULA will bind and inure to the benefit of each party’s successors and assigns, provided that Customer may not assign or transfer this
EULA, in whole or in part, without Overland’s written consent.
This EULA will be governed by and construed in accordance with the laws of the State of California, United States of America, as if performed wholly within
the state and without giving effect to the principles of conflict of law.
No failure of either party to exercise or enforce any of its rights under this EULA will act as a waiver of such rights.
Any waivers or amendments will be effective only if made in writing by non-preprinted agreements clearly understood by both parties to be an amendment
or waiver and signed by a representative of the respective parties authorized to bind the parties.
If any portion hereof is found to be void or unenforceable, the remaining provisions of this EULA will remain in full force and effect.
This EULA is the complete and exclusive agreement between the parties with respect to the subject matter hereof, superseding and replacing any and all
prior agreements, communications, and understandings (both written and oral) regarding such subject matter.
Any notice, report, approval or consent required or permitted hereunder will be in writing and will be deemed to have been duly given if delivered personally
or mailed by first-class, registered or certified US mail, postage prepaid to the respective addresses of the parties. The prevailing party in any action to enforce
this EULA will be entitled to recover costs and expenses including, without limitation, reasonable attorneys’ fees.
A material breach of this EULA adversely affecting Overland’s proprietary rights in the Software would cause irreparable injury to Overland for which
monetary damages would not be an adequate remedy and that Overland will be entitled to equitable relief in addition to any remedies it may have hereunder
or at law.

cards, internal monitoring LEDs and ambient temperature sensor.
This chassis assembly contains 48 drive bays, arranged in two groups each comprising 4
banks of 6 bays, located in the front section of the chassis (see Figure 1-5). Each drive bay
accommodates a plug-in drive carrier module which houses low profile, 1 inch high, 3.5 inch
form factor drives. Drives are loaded via the top of the enclosure.
Note: A drive bay is defined as the space required to house a single, 1.0 inch high, 3.5 inch
disk drive in its carrier module.
Located between the two groups of drive bays are the Enclosure Interface Processor (EIP)
card and the SAS-SATA Channel cards, which are pre-installed.
An integral Enclosure Display Panel assembly is mounted at the front of the chassis
assembly which includes:
• An Audible Alarm and an Alarm Mute switch.
• An LED status display.
• An LCD which indicates Power Supply/Cooling Module, Fan, or System failure.
• A Power On/Standby button.
At the rear, the chassis assembly contains six module bays to house the three Power
Supply/Cooling modules, two FC-SAS RAID Controller modules (ULTAMUS RAID 4800)
or SAS EBOD I/O modules (ULTAMUS RAID 4800x), and one optional ACRS (AC
Redundant Switch) module.

The Enclosure Interface Processor (EIP) card contains a processor which interfaces to
devices on the baseplane, and RAID Controllers or EBOD I/O modules to monitor internal
functions and mode settings. Monitoring information from the EIP card is displayed on the
LEDs and the LCD located on the Display Panel. Mode settings are selected via the
Enclosure switches, mounted on the backplane which is located between the drive area and
rear module bays.
The EIP card incorporates the following LED indicators:
• Fault LED.
• Address Mode Error LED (not used).
The EIP card is a serviceable PCB which may be replaced by trained personnel.
SAS-SATA Channel Card
The SAS-SATA Channel cards each contain SAS expander devices that provide switchbased connectivity to SATA drives in the enclosure. In dual port applications, a SATA port
selector located on a dongle on the drive carrier is used to enable dual port capability.

Front Panel - Drive Activity LEDs
The front panel assembly includes 48 Drive Activity LEDs, located along the bottom of the
panel and arranged in twelve groups of four LEDs for the column of drives, shown below
and on the following page.
Drive Activity LEDs are illuminated when drives are installed and will flash during drive
I/O activity.
Figure 1-12: Front Panel Showing Drive LEDs
8 X 10400121-101-SG 06/07
ULTAMUS RAID 4800 Setup Guide Chapter 1
Important: Individual drive fault indications are provided via the Status LED on the drive
carrier module. If a drive fault occurs, the software will notify you of the problem. Access
the enclosure and open the lid, observing for which disk drive carrier is indicating a fault
by illuminating its Status LED. (Figure 1-13)
The Activity LEDs on the front panel are positioned in relation to the disk drive bays found
at the top of the enclosure. They are listed numerically from the front to the rear using the
numbers 1-4. The numbers indicate the slot for that column of drives. For example the left
most lower Activity LED (1) is the drive slot 1 in the first column from the left, as viewed
from above. Likewise, in the same column of Activity LEDs the (4) LED is for the fourth or
last drive in the first column from the left of the enclosure, also as viewed from above.

Enclosure Switches
The following switches are mounted on the backplane, located between the drive and rear
module bays. They are only accessible when the enclosure lid is fully open. These switch
settings are only read during the power up cycle.
The two switches are provided for configuring the operating mode of the enclosure. The
switch settings are detailed in Table 2–2 on page 39. The two modes are RAID Chassis and
Expansion Chassis. A switch setting is also provided to mute the audible alarm for all
events.

Plug-in Modules
The enclosure requires the following modules for normal operation: Power Supply/Cooling
modules (3), RAID Controllers (2) or EBOD I/O modules (2), and an ACRS module (1).
Power Supply/Cooling Module
Three auto ranging AC 450W Power Supply/Cooling modules are supplied mounted at the
rear of the enclosure as part of the core product. The Power Supply/Cooling module
operating voltage range is 100 - 240V, and is selected automatically. When used with the
optional ACRS module and bifurcated power cables, it must operate at a reduced range of
200 - 240V.
Note: If the optional ACRS module is not utilized, either 110V or 240V must be applied to
all three Power Supply/Cooling modules.
Under normal operations, all three power supplies are providing power to the chassis. In
this situation, all three power supplies share the load equally. Show a power supply fail,
thee two remaining power supplies continue to share the load. This of course assumes that
there was power being applied to all three power supplies.

Under normal operations, all three power supplies are providing power to the chassis. In
this situation, all three power supplies share the load equally. Should a power supply fail,
the two remaining power supplies continue to share the load. This of course assumes that
there was power being applied to all three power supplies.
ACRS Module (Optional)
If installed, the function of the ACRS (AC Redundant Switch) is to provide failover of mains
supply in the event one power source fails. If such a failure occurs, the circuitry will ensure
that there is no disruption to the system.
The optional ACRS module is a stand-alone module (available separately) with no internal
connectors and is installed in the center module bay at the rear of the enclosure. The
module includes two Input IEC 320 plugs and one Output IEC 320 socket.

ULTAMUS RAID 4800 Setup Guide Chapter 1
Figure 1-17: Optional ACRS Module
Note: Most of the cabling diagrams depict the use of the ACRS module.
When an ACRS is not utilized, the user should ensure that all three power supplies are
powered by individual power cords (either 110V or 240V). If one of the power supplies fails,
the remaining two pick up the load. However, unless all three power cords are powered by
different mains, there is no protection against the loss of power to the mains supply that
affects more than one power supply/cooling module.
When an ACRS is utilized, it is meant to be used with two independent 200 - 240V power
mains or phases. In the event one of the power sources fail, the ACRS along with the
bifurcated (or four individual) power cables, ensures that mains power is routed to all
power supply/cooling modules. In the event that both power mains remain good, but a
power supply fails, power is still applied via the bifurcated or individual power cables and
the two remaining operational power supplies.
RAID Controller Module
The ULTAMUS RAID 4800 enclosure houses two RAID Controller modules shown in
Figure 1-18.
Figure 1-18: RAID Controller Module (Shown Upside Down)
12 X 10400121-101-SG 06/07
ULTAMUS RAID 4800 Setup Guide Chapter 1
The plug-in RAID Controller modules have been designed for integration into the
enclosure, utilizing Fibre Channel interconnections with the host computer system and a
SAS expansion port. It supports 512 MB or 1GB cache memory configuration.
The backplane circuit board incorporates connections to each of the SAS ports within the
RAID Controller modules.
Processors housed on the RAID Controller modules provide enclosure management and
interface to devices on the Baseplane, Power Supply/Cooling module, SAS-SATA Channel
cards and EIP card to monitor internal functions. These processors operate in a dual active
configuration to allow for failover and failback.
The module incorporates LED indicators, shown in Figure 1-19. Refer to Table 1–4 for
details of the LED status conditions.

The RAID Controller module has the following external ports.
• Two external (Host) ports that allow for the installation of Small Form Factor Pluggable
(SFP) modules, with auto-bypass at the output. Either or both of these SFP ports can be
used to provide connections to the Host controllers. Each host port operates at 4 Gbit/sec,
giving an effective speed of 8 Gbit/sec; these ports are also backwards compatible with 2
Gbit/sec hosts.
• A SAS expansion port provides for disk expansion utilizing a RS-4835-E3-XPN
enclosure via a SFF-8470 connector.
• A RJ-45 10/100BASE-T Ethernet port allows the controller to be connected to a network
to enable out-of-band management and monitoring using the Embedded ULTAMUS
RAID Manager software.
• An RS-232 serial interface allowing access to the VT-100 firmware-based RAID
Configuration Utility for configuration and monitoring utility.

ULTAMUS RAID 4800 Setup Guide Chapter 1
Caution: The RS-232 port uses a USB-type connector, however do not use a standard USB
cable to attach to this port. It requires a special cable available from your supplier. The
RS-232 port is for Ethernet connections only. Do not connect to a telecommunications
network.
Backup Battery
The RAID Controller module includes a removable backup battery that provides protection
of the cache contents if the AC power fails. The amount of time the data is protected is
available via the software management interface and is a function of the size of the cache.
The battery is a Nickel Metal Hydride battery pack and is serviced as a whole assembly
(field swappable).
