Figure 43. Typical AC Power Cable Connections to PSUs
CAUTION:
Always remove the power connections before you remove the PCM or PSU from the enclosure.
When bifurcated power cords ("Y" leads) are used, these cords must only be connected to a supply range of
200-240 VAC.
Grounding Checks
The product must only be connected to a power source that has a safety electrical ground connection.
If more than one enclosure goes in a rack, the importance of the earth connection to the rack increases,
because the rack has a larger "EARTH LEAKAGE CURRENT" ("TOUCH CURRENT").
Examine the earth connection to the rack before the switch-on: an electrical engineer who is qualified to the
appropriate local and national standards must do the examination.
System Configurations
If you connect the enclosure to a host, ensure that you have the following items:
• SAS HBA
• MiniSAS HD to MiniSAS HD cable or MiniSAS HD to MiniSAS cable
• Power cord
• Rack kit
If you connect the enclosure to a Lenovo Storage DS-series as the expansion enclosure, ensure that you
have the following items:
• Lenovo Storage DS-series
• MiniSAS HD to MiniSAS HD cable
• Power cord
• Rack kit
For Option Compatibility Matrix (OCM) for use with the enclosure, refer to

System Cabling
Note: Configuration details in this section are for a typical enclosure.
Note: The maximum number of SAS devices depends on the number of HBA or RAID adapters in use or
maximum SAS device supported for a single HBA or RAID adapter. For detailed information, refer to the HBA
or RAID adapter specification and the Interoperability Matrix for the specific model Storage enclosure.
