Product overview
The NAS1000 family o f systems is an ideal solution when looking for robust and capable storage
devices integrating Network-Attached S torage (NAS)
1
functionalities. When c onnected to a n etwork,
thanks to an integrated Ethernet-to-SATA controller, NAS1000 systems make available two hard disk
configurations: in RAID0 or RAID1. In addition, the systems can be powered using Power - overEthernet (PoE) technology
2
NAS1000 systems allow for different installation possibilities: they can be installed using two mounting
brackets, or inserted inside a security enclosure that has a locking mechanism and allows you to install
the system while avoiding unauthorized removal.
.
The rugged design of NAS1000 systems allows their deployment in railway applications prone to harsh
environmental conditions.

WARNING!
It is the responsibility of the system integrator to ensure that all connections are compliant with
relevant standards for each type of interface.
DragonTech
18
WARNING!
The degree protection on the system is only obtained by covering the connectors properly. Be
careful to use cables that ensure the seal of the connector. Unused connectors have to be covered
with an appropriate plug. An improper cover of the connectors may result in damage to the system
and other system’s components due to a leaking seal.
WARNING!
See the paragraph Operating characteristics on page 23 for the pow er requirements of the product.
Use only cables that are appropriate to the power rating of the system.
Make sure that during installation the system maintains a proper grounding.
Installation notes
NOTE:
The device can operate in vertical, transversal and longitudinal orientations.
WARNING!
Verify that the addition of the system does not cause instability or damage to the mounting location.
Firmly secure the system.
Be aware of potentially haz ardous situation when mounting the system (e.g. falling down). If
required, use stiffeners to reinforce the mounting area.
NOTE:
When the unit is mounted, ensure adequate clearance distance for cabling and air circulation: there
must be sufficient space to connect the cables and for the maintenance operations.
WARNING!
Make sure the temperature and humidity will stay within the ranges specified in the Operating
characteristics paragraph on page 23.
Be aware of other devices that may raise the ambient temperature in the installation area, also the
radiated heat of the system itself.
