Connecting optional SAS expansion enclosures: 2076-92F
After you install 5U expansion enclosures into the rack, you must connect them to
each system that will use them. The system requires software version 7.8.0 or later.
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 systems, Storwize V7000 Gen2+ control enclosures,
and 2U expansion enclosures, the blue pull tab must be below the cable (▌1▐ in
Figure 116).
v For 2076-92F 5U expansion enclosures, the blue pull tab must be above the
connector (▌2▐ in Figure 116).
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.
