2.3.3 Expansion connections
A SAS host link cable is bundled per expansion package. If you need to purchase other cables, or if you
need other cables of different lengths, contact your vendor.
Before configuring the expansions, you must take note of the following important points:
•
For a cleaner and clutter-free system assembly, have a carefully planned routing paths when
connecting between systems.
•
All SAS cables are sensitive and must be handled with care. DO NOT bend or twist the cables
when connecting between systems.
Setting the expansion IDs
Each expansion system must have a unique ID and you can configure the ID via the rotary ID switch. To
set the expansion IDs, use a small flat-blade screwdriver.
You must take note of the following when setting the IDs on the expansion system:
•
Set the IDs from 1 to 15. The order starts from the expansion enclosure that is closest to the
managing GSe Pro enclosure.
•
Ensure to set a unique ID on each expansion enclosure so that the SAS WWN addresses of the
disk drives are properly assigned. The system firmware automatically manages these addresses.
