Power Cords
Use only tested and approved power cords to connect to properly grounded power outlets or insulated
sockets of the rack's internal power supply.
If an AC power cord was not provided with your product, purchase one that is approved for use in your country
or region.
CAUTION
To avoid electrical shock or fire, check the power cord(s) that will be used with the product as
follows:
• The power cord must have an electrical rating that is greater than that of the electrical current rating marked
on the product.
• Do not attempt to modify or use the AC power cord(s) if they are not the exact type required to fit into the
grounded electrical outlets.
• The power supply cord(s) must be plugged into socket-outlet(s) that is /are provided with a suitable earth
ground.

Rackmountable Systems
CAUTION
Always install rack rails and storage enclosure according to Ultrastar Serv24 product documentation.
Follow all cautions, warnings, labels, and instructions provided within the rackmount instructions.
Reliable grounding of rack-mounted equipment should be maintained.
If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment
may be greater than room ambient. Therefore, consideration should be given to installing the equipment in
an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer.
Observe the maximum rated ambient temperature, which is specified in the product documentation.
For safe operation of the equipment, installation of the equipment in a rack should be such that the
amount of air flow is not impeded so that the safe operation of the equipment is not compromised.
2.6
Safety and Service
All maintenance and service actions appropriate to the end-users are described in the product
documentation. All other servicing should be referred to a HGST-authorized service technician.
To avoid shock hazard, turn off power to the unit by unplugging both power cords before
servicing the unit. Use extreme caution around the chassis because potentially harmful voltages are present.
When replacing a hot-plug power supply, unplug the power cord to the power supply being replaced
before removing it from the Ultrastar Serv24.
