Connecting the optional 2076-92F SAS expansion enclosures
After you install expansion enclosures into the rack, you must connect them to
each system that will use them. The system requires software version 7.8.0. Do not
connect the expansion enclosure if software version 7.8.0 is not installed on the
system.
About this task
This task applies if you are installing a 2076-92F expansion enclosure.
Note: When you insert SAS cables, ensure that the connector is oriented correctly
to the control enclosure and expansion enclosure.
v For Storwize V7000 Gen2 or Storwize V7000 Gen2+ control enclosures, and
2145-24F or 2145-12F expansion enclosures, the blue pull tab must be below the
cable (▌1▐ in Figure 114).
v For 2076-92F enclosures, the blue pull tab must be above the connector (▌2▐ in
Figure 114).
v Insert the connector gently until it clicks into place. If you feel resistance, the
connector is probably oriented the wrong way. Do not force it.
v When inserted correctly, the connector can be removed only by pulling the tab.
Be aware of the following guidelines when you attach the cables to the SAS ports.
