Safety Guidelines

  Important info: Do-it-yourself repairs not covered in this manual will invalidate the warranty.

Safe handling

The 8-bay Rackmount NAS must run with all of its parts and units in place. In order to comply with applicable safety, emission and thermal requirements, no covers should be removed and all drives must be installed according to the instructions (see Setting Up).

Permanently unplug the unit if you think that it has become damaged in any way.

The 8-bay Rackmount NAS features three parts that are hot-swappable: drives; fans; and power supply units). The NAS can remain powered on when replacing a hot-swappable part. For all other types of maintenance and physical troubleshooting, shut down and disconnect power from the NAS. Only qualified technical service personnel should be allowed to maintain the NAS.

Shut down and unplug the unit before moving it.

  Caution: If this equipment is used in a manner not specified by Seagate, the protection provided by the equipment may be impaired.


Power supplies

The 8-bay Rackmount NAS must be operated from a power supply input voltage range of 100 to 240 VAC, 50 to 60 Hz.

Make sure that the socket outlets are located near the equipment and are easily accessible.

Before removal/replacement of a power supply, disconnect the power supply cable for complete isolation.


Use caution when replacing the battery:

  • There is a strong risk of explosion if the battery is replaced by an incorrect type.
  • Dispose of used batteries according to the applicable laws for your region.


A safe electrical ground connection must be provided to the power cord. Check the grounding of the enclosure before applying power.

Provide a suitable power source with electrical overload protection to meet the requirements laid down in the technical specification.

Never expose your device to rain, or use it near water, or in damp or wet conditions. Never place objects containing liquids on the enclosure, as they may spill into its openings. Doing so increases the risk of electrical shock, short-circuiting, fire, or personal injury.

Always unplug the device from the electrical outlet if there is a risk of lightning or if it will be unused for an extended period of time. Otherwise, there is an increased risk of electrical shock, short-circuiting, or fire.

Hot surfaces (heat sinks) are exposed when the enclosure top cover is removed. Disconnect power and allow the enclosure to cool before working inside the system.

When pulled out from the rack, the enclosure must not be used as a shelf to support any other object.

  Caution: Do not remove covers from the PSU: there is a danger of electric shock inside. If the PSU fails during the warranty period, return it to Seagate.


  Warning:Removing the enclosure cover when the NAS is powered on will reveal moving parts, specifically the rotating fan blades. You must remain vigilant when opening the enclosure cover. Above all, show extreme caution with the fans and other moving parts within the 8-bay Rackmount NAS.

Rack system safety precautions

The rack cabinet must be capable of supporting the total weight of the installed enclosure(s) and the design should incorporate stabilizing features suitable to prevent the cabinet from tipping or being pushed over during installation or in normal use.

When loading a rack cabinet with the units, fill from the bottom up and empty it from the top down.

Do not add any load onto the 8-bay Rackmount NAS when it is mounted on its rack rails and installed on its slide.Doing so can bend the rails and prevent the slide from proper operation.

The rack cabinet design should take into consideration the maximum operating ambient temperature for the unit, which is 35°C.

The rack cabinet should have a safe electrical distribution system. It must provide overcurrent protection for the unit and must not be overloaded by the total number of units installed in the rack. When addressing these concerns, consider the electrical power consumption rating shown on the product.

The electrical distribution system must provide a reliable ground for each unit and for the cabinet.

The power supply unit has a ground leakage current of 3.5mA. The design of the electrical distribution system must take into consideration the total ground leakage current from all the power supplies in all the units.

When configured, the cabinet must meet the safety requirements of IEC 60950-1 2nd edition.

  Caution: To avoid danger of the cabinet toppling over, under no circumstances should more than one enclosure be drawn out of the rack cabinet at any one time.

Rack installation prerequisites

The Seagate 8-bay Rackmount NAS enclosure is designed for installation into an industry standard 19-inch rack cabinet subject to the following requirements:

  • There must be a minimum depth of 430mm (16.9 inches) from rack posts to the  maximum extremity of the enclosure (excluding rear cabling).
  • The rack must be able to support enclosures weighing up to 20Kg (45 lb.).
  • There must be a minimum gap of 25mm (1 inch) between the rack cover and front of the enclosure.
  • There must be a minimum gap of 50mm (2 inches) between the rear of the enclosure and the rear of the rack in order to maintain the correct air flow around the enclosure.
  • Use in a fully enclosed rack installation is not recommended.
  • The rack design should take into consideration the maximum operating ambient temperature for the unit,which is 35°C.
  • The system must be operated with a low pressure rear exhaust. The back pressure created by rack doors and obstacles must not exceed 5 Pascals (0.5mm water gauge).

The top cover on the rear of the enclosure provides access to the RAM, hard drives, and riser card slot in the motherboard. Do not remove the top cover on the rear of the enclosure unless you are performing maintenance recommended by Seagate technical support. The unit must be turned off and allowed to cool down before removing the rear cover. Potential hazards include the battery and hot surfaces.

When placing the covers on the NAS, make certain that:

  • The front cover is secured by snapping the latches into place (this is to prevent users/operators from accessing service areas).
  • The rear cover is screwed into place with the original screws.

Equipment handling precautions

Observe all conventional ESD precautions when handling 8-bay Rackmount NAS internal components. Avoid contact with backplane components, module components, etc.

Drives are fragile and must be handled with care during removal/replacement.

Data security

Any loss, corruption, or destruction of data while using a Seagate drive or a Seagate drive system is the sole responsibility of the user, and under no circumstances will Seagate be held liable for the recovery or restoration of this data. To help prevent the loss of your data, Seagate highly recommends that you keep TWO copies of your data: one copy on your NAS; and, a second copy on one of the following:

  • Direct-attached storage (DAS)
  • A second NAS
  • Some form of removable storage or archival media
  Important info:1GB = 1,000,000,000 bytes. 1TB = 1,000,000,000,000 bytes. Once formatted, the actual available storage capacity varies depending upon the operating environment (typically 10-15% less).
