The two GBIC output ports are for attaching the optional GBICs to the
storage unit.
The optional GBICs (input and output) are for attaching your optical cables
to the storage unit, then to the controller or additional storage unit. Insert
the GBICs in the expansion unit GBIC ports and attach your FC cables to
the GBICs, then connect the FC cables to the controller or additional
storage unit.
These amber LEDs light if the storage unit tray ID settings for the ESM
boards do not match. In this case, the storage unit uses the tray number of
the left ESM board.
These amber LEDs light when no valid input signal is detected and when
no data is passed through the port. When no cable is connected to the port,
the LEDs also light. Both ports on the ESM board are bypassed and the
LEDs are lit in the event of an ESM board fault. In this case, the ESM Fault
LED is also lit.
Use these levers when removing and inserting the ESM boards.
These green LEDs are lit when there is power to the ESM board.
These amber LEDs light if the storage unit overheats.
These switches assign the physical addresses of the disk drives and the
system management processors that are participating in the loop, and they
identify the storage unit. The base switch (x1) sets the IDs of the disk drives
on the loop. The settings of both the base ID switch (x1) and the extended
ID switch (x10) together is the storage unit ID. The switches set the storage
unit ID using values of 00 through 99. The base ID switch (x1) is for the
ones position and the extended ID switch (x10) is for the tens position.
