SCSI Cabling Guidelines
Always be sure that the servers attached to the storage system are powered down and
power cords are disconnected before connecting SCSI cables.
IMPORTANT: Before installing the Smart Array Multipath software on a server with a
Microsoft operating system, connect only one of the SCSI cables from each server to the
MSA500 system. Leave the second SCSI cable for the redundant path disconnected until
after the multipath software is installed.
For SSP cabling configurations, refer to “Selective Storage Presentation” in
Chapter 4.
Power Cords
The power cords 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 for the product. The voltage and current rating of 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 mm² or 18 AWG. If you are using
18 AWG, your maximum length may be up to 12 ft.
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 system.
To connect AC power cords:
1. Connect the power cords to the power supplies.
2. Connect the power cords to the AC outlet.
