SAS cabling guidelines

Observe the following guidelines:
Only use supported SAS cables with 3-GB connectors
Always be sure that the servers attached to the storage enclosure are powered
down and power cords are disconnected before connecting SAS cables.

Power cords

The power cord should be approved for use in your country. The power cord
must be rated for the product and for the voltage and current marked on the
electrical ratings label of the product. The voltage and current rating for the cord
should be greater than the voltage and current rating marked on the product. In
addition, the diameter of the wire must be a minimum of 1.00 mm
your maximum length may be up to 3.66 m (12 ft).
To connect AC power cords:
1. Connect the power cords to the power supplies.
2. Connect the power cords to the AC power source.
WARNING: To reduce the risk of electric shock or damage to
the equipment:
• Do not disable the power cord grounding plug. The grounding
plug is an important safety feature.
• Plug the power cord into a grounded (earthed) electrical outlet
that is easily accessible at all times.
• Unplug the power cord from the power supply to disconnect
power to the equipment.
• Do not route the power cord where it can be walked on or
pinched by items placed against it. Pay particular attention to
the plug, electrical outlet, and the point where the cord extends
from the storage system.
