1. Introduction
1.1 Scope
This document describes the installation and operational features of Targa Series 4
2nd generation Gb Ethernet Network Attached Storage (NAS) Data Transfer System.
1.2 Data Transfer System Overview
Targa Systems Series 4 NAS Data Transfer System has three (3) components:
DTU - Data Transfer Unit
DTD - Data Transfer Device
GSU - Ground Support Unit
DTU - Data Transfer Unit
Targa System’s Series 4 Ethernet DTU is a rugged, field
deployed unit providing dual 10/100/1000 Mbps
Ethernet network interconnections as well as the
electrical and mechanical infrastructure support for
the removable Data Transfer Device.
The DTU, based on the ARINC CDU style, (DZUS rail
mount) form factor is equipped with an RTCA-DO-
160C, Cat Z compliant 28VDC power supply and two rear
panel mount, MIL-C-38999 connectors; J1 for +28Vdc power and additional auxiliary
control and status signals; J2 for the dual Ethernet ports.
The DTU front panel accommodates four (4) DZUS ¼ turn fasteners and the DTD
access door. The access door is opened by simply rotating the ¼ turn door latch
counter-clockwise. This action releases the door lock mechanism and as the door is
opened, an optical sensor is tripped and the DTU executes an orderly power
shutdown of the network links, flushing cached data to the DTD and then removing
power from the DTD. This is an important feature to meet explosive atmosphere
requirements and to avoid data corruption due to operator actions during data write
operations. Once the door is open, the DTD is inserted through the front panel
aperture and gentlypushed into place. When closed, the door is locked by simply
rotating the latch clockwise.
DTD - Data Transfer Device
The Targa Systems Series 4 SATA Data Transfer Device (DTD) is a rugged
removable data storage unit containing a solid state 2.5” FLASH SATA disk enclosed
in a machined aluminium case with a high reliability, low insertion/removal force
connector. The S4 SATA DTD is designed with a flange on one side to prevent
improper insertion into the Data Transfer Unit (DTU) receptacle, or insertion into
other Targa Systems Series 4 Data Transfer Units that support SCSI or ATA type
Data Transfer Devices.
When the DTD is inserted into either a Data Transfer Unit (DTU) or a Ground
Support Unit (GSU), an optical sensor is used to detect the presence or absence of a
reflective label on the end plate. When reflected light is detected, the DTD is
mounted by the DTU / GSU as a read only device.
GSU - Ground Support Unit
The Series 4 GSU is a desktop, office grade unit
providing 10/100/1000 Mbps Ethernet network
interconnections to ground based data
preparation/retrieval computer systems as well as
electrical and mechanical support for the
removable Data Transfer device. The GSU front
face is designed with a keyway corresponding to the SATA DTD flange to ensure
that only the correct DTD type can be inserted and that the DTD is inserted in the
proper orientation. Data can be transferred to/from the DTD when inserted into the
GSU using widely supported file transfer protocols such as TFTP, FTP and NFS or
using the iSCSI block I/O protocol.

3. Targa NAS DTU Operations – Overview
Targa Systems Ethernet NAS DTU is a dedicated data storage device intended to
be connected directly to a network to provide centralized data access and storage
via a removable Data Transfer Device containing a SATA FLASH disk . The
following is a brief overview of some of the systems operational features.
3.1 DTD Use and Handling
Targa's Ethernet DTU/GSU is equipped with a door sensor to detect door
open/close status. Upon detection of a door open event the DTU/GSU will
execute the Door Open algorithms as outlined below.
To install the DTD, open the DTU/GSU access door and slide the DTD through the
faceplate slot until it is fully engaged in the receptacle.
To remove the DTD, open the DTU/GSU access door, firmly grip the exposed end
of the DTD and pull to extract.
Note: The DTD to DTU interconnect is via a low insertion force connector rated
over 100,000 insertion /removal cycles. The user must, however, ensure
that no foreign matter is trapped in the DTD connector before insertion into
the DTU/GSU to prevent damage to the inter-connecting pins.
3.2 Opening the DTD Access Door – DTD protection
Targa Systems DTU and GSU products are designed to protect against data file
corruption if the access door is opened while there is disk activity.The DTU and
GSU products are equipped with protective circuitry to detect the DTD access door
being open, DTD installed as well as a DTD power on/off control. These features
are used to activate the DTD shutdown process for data integrityas well as
meeting explosive atmosphere requirements.
10

Targa Systems Division
S4 Ethernet NAS DTS Installation Guide 32003272-1 Rev 5
When a Door Open event occurs, the following sequence is performed:
- FTP and NFS processes for that DTD are terminated
- DTD filesystem is unmounted
- Write pending ext4 file system journal to DTD
- Turn DTD power Off
When the Door is closed, the following sequence occurs:
- DTD is initialized
- If a valid file system is detected – the DTD is mounted
- If reflective label detected – DTD is mounted Read only
NOTE: Depending upon unit activity, it may take the DTU several seconds to
complete all pending data writes to the DTD. Users should wait
approximately 3-5 seconds after the door is opened before removing the
DTD.
3.3 DTD NAS Partition File Structures
Data is stored on DTD NAS partitions using the ext4 filesystem (extended
filesystem version 4) with journaling capabilities. A journaling filesystem keeps a
log of filesystem transactions and in the event of a major uncontrolled event, such
as a power failure, the journal will be played back during the next disk mount
process and any filesystem inconsistencies automatically corrected.
This does not mean that data sent to the DTU immediatelyprior to a power failure
cannot be lost, but it does mean that the existing data and file structures will not be
corrupted.
Due to the overheads associated with the journaling filesystem, Targa
recommends that the DTD be periodicallyreformatted using the DTU Configuration
utility.
3.4 DTD Write Protect
The DTD can be write protected by installing one of
the reflective write protect labels (Targa P/N
32003256) supplied with the DTD. When a write protect
label is detected by the DTU or GSU the DTD will be mounted
as a read only device.
3.5 DTD Data Reliability
The Data Transfer Device uses a sophisticated SATA FLASH disk as the data
storage medium providing enhanced data reliability via the following mechanisms:
· All erase/write operations are performed in a closed loop operation to verify
data has been erased and programmed correctlywith the proper voltage
margins.
· Data is checked with a powerful Error Correction Code (ECC) that offers a
high degree of data protection.
· Built in defect management with automatic sector reassignment based on
detected memory errors.
NOTE: DTDs are shipped from Targa
with an EXT3 partition for compatibility
with older systems. See 4.7.1 for
information on reformatting to EXT4
11

Targa Systems Division
S4 Ethernet NAS DTS Installation Guide 32003272-1 Rev 5
3.6 Power Fail
The DTU’s 28Vdc power supply features a power fail detection circuit along with a
50 millisecond holdup capability to support DTU operations during power
interruptions to ensure data integrity.
When a Power Fail is detected (< 17Vdc), the following sequence occurs:
Power Fail signal debounced, ignored if < 1ms
Ethernet File data transfers are suspended
All DTD I/O operations are suspended.
If the input power recovers within the 50msec holdup period, the DTU will resume
normal operations.
In the event of an extended brown-out; when the input power recovers the DTU
will resume operations – as if there had been a door open/close sequence.
Any suspended I/O is written to the DTD
Network connections are reset
DTD(s) remounted
Note: The power fail feature is not supported bythe desktop GSU version.
3.7 Security Erase

data must be “Submitted” for the associated DTU configuration data files to be
updated. When all of the changes have been made the Targa DTU must then be
rebooted for the new configuration data to take effect.
Each DTU Configuration page, that provides access to user controlled parameters,
will display the “Submit Changes” button:
Submit Changes: Used to submit the data as entered on the page into the
DTU configuration files. When the configuration files have been
updated, all DTU subsequent configuration pages will display the
following message, until a DTU reboot or power cycle has been
performed:
The DTU's configuration has changed.
A reboot is required for the changes to take effect
To initiate the DTU reboot – select “DTU Reboot” on the DTU
Control Panel
Reset Clears the changes as entered on this page and reverts to the
current settings.

4.3 DTU-INFO Page
Displays Basic DTU information:
Model#: Targa DTU Model #
Serial#: DTU serial number YYMMxxxxxx
YYMM is the DTU date of
manufacture
xxxxxx is the DTU MAC
address
Firmware: DTU firmware version and part
number
Config Mode: Must be enabled to update
unit configuration data.
See section 2.6.3
System Time: Current time within the DTU
At power up defaults to 00:00:00 January 1, 1970 GMT
DTU time can be set via 2 mechanisms
- FTP Site Command “SETTIME”
- rdate server -time is requested at power-on (refer to the DTU
Network configuration page for details)
Uptime: Length of time that the DTU has been operational.
Uptime can be used to determine if the DTU has experienced a
power failure recovery since it was last accessed (ie: if your current
directory has changed back to the default mount point due to
system reboot)
Load Avg: Measure of average DTU CPU utilization use as a % over time for
the past: 1 min, 5 min, 15 min
Load Avg can be used as a reference, during test and integration to
determine if there are sufficient resources available to handle more
client sessions or file transfers. Note: 1.0 = 100% and loads > 1.0
are normal.
Power State: Status of input power:
Good - input power within range
Power-fail - input power is < 17Vdc and DTU is operating in
power-fail protection mode.
Refer to Section 3.6 for more details.
DTD State Status of DTU access door as well as DTD #1 [and DTD #2 ]

DTU Features
Erase Input / Erase Algorithm:
The Targa DTU supports a
remote sourced Erase input
signal used to activate a user
specified DTD Security Erase
algorithm. Refer to Appendix B for details on the supported Sanitize / Secure
Erase algorithms.
If the Erase input is disabled, the Erase Algorithm entry is not applicable.
Factory default is disabled.
Erase Input Signal: (Secure_Erase- refer to 2.6.3 & 3.7)
Active low input signal. Signal must transition from Off state (logic high) to On
state (logic low) and be logic low for a minimum of 300msec for DTU to
activate erase. If the signal is detected as logic low at power up or at door
closure the signal is disqualified until it returns to the logic high state (for a
minimum 300msec). If the Erase Input feature is disabled the signal is not
monitored.
Refer to the FTP Site command “dtdsanitize” for details on the ethernet
commanded DTD Secure Erase.
Enable Temp Alerts: Enabled Disabled
The DTU is equipped with an on-board temperature sensor that can be used
to monitor the internal temperature. The temperature monitoring process can
also, when enabled, issue an alert at a user specified temperature. Refer to
the FTP Site command section for details on how to read unit temperature
and detect a temperature alert.
Factory default is disabled.
Temperature Alert at: Default: 90ºC Input range: 80ºC to 100ºC
Temperature Alert value is used only when Temp Alert is enabled

Firmware Upgrade
The Targa DTU firmware is field upgradeable using a DTD as the transport
mechanism.
To upgrade DTU firmware:
1. The DTU “Config Enable-” input must be connected to ground.
2. A DTD installed with the new firmware code stored in /dtd/a/part1 as:
targa-firmware.edtu if not modifying unit configuration
or targaconf-firmware.edtu restore factory default configuration
Note: If both files found: targa-firmware.edtu takes precedence
3. Firmware upgrade process must be enabled and the upgrade initiation
mechanism selected. The options are:
Disabled - firmware upgrade process disabled
On-boot - at DTU startup, the DTD will be read and if either of the
specified DTU firmware files are present, the DTU
firmware will be updated.
Manual - Update process will be initiated upon receipt of the FTP
Site “SITE UPDATEFIRM” command at which time, the
DTD will be read and if either of the specified DTU
firmware files are present, the DTU firmware will be
updated
On-boot, Manual– either update processes can be used
Notes: - The firmware update process can take anywhere from 3-5 minutes
and MUST BE monitored on the COM2 Log port. During the
update process a stream of “….” will be output and a completion
message issued. DO NOT POWER OFF UNTIL UPDATE IS
COMPLETE. Any Error Conditions encountered during the update
process are output on the COM2 Log port.
- Upon completion of the firmware update process the DTU will
reboot.
- If the targa-firmware.edtu file is used, then the DTU must be re-
booted a 2nd time for the existing configuration files to be transferred
into the new operational code space . If this is not done a DTU
unconfigured error will be reported in FTP Site “Healthcheck” and
DTU functionality may be compromised.
- To install previous firmware versions: Onlythe manual process will
support loading older firmware and only with the
targaconf-firmware.edtu file. This ensures synchronization of
configuration files to the operational code set.
- F/W 3.1.4 and onward - Factory default is now manual.
COM2 Log Verbosity
The Targa DTU provides an RS-232 system monitor port designated COM2.
COM2 Log output is: RS-232, 8bit ASCII, no parity, 1 stop bit at 115.2K BAUD
Select the messages output level:
Off - no message output
Low - Critical messages only
Medium - Warnings, Errors and Critical messages
High - all messages including debug messages
