Modular Storage Shelf BA35x-Sx Subsystem
There may be up to eight StorageWorks building blocks (SBBs) on each modular storage
shelf BA35x-Sx subsystem. The StorageWorks Building Block (SBB) slots are numbered 0
through 7 from right to left with the power supply SBB in slot 7. On the IP simplex system,
the storage SBBs are in slots 0-6. On the duplex system, the available storage SBBs are in
slots 0-5.
_____________________________ Note____________________________
The SCSI address for the SSB device is defined automatically by the SSB slot
location.

After power is supplied to the IP Platform, observe the status LEDs for the following
successful indications:
•
On a power supply SBB, both green status LEDs should be on.
•
On a storage SBB, the green device activity LED is either on, flashing, or off. The amber
device fault LED is off.
