Figure 11. Switch Card (with or without BBU)
The switch card contains two separate switches:
FC-AL Address switch 5
Below the FC-AL Address switch is a 4-bit dip switch called the option switch.
Option Switch
10
ProFibre Storage Array: Operator's Guide
This switch can be set to a value between 0 and 7. It controls the FC-AL
addresses used by the ProFibre Storage Array. For example, if the switch is
set to 5, the FC-AL address of the disks in slots 1 to 10 are then 50 to 59
(hexadecimal). In this case, the address of the enclosure services is 5A
(hexadecimal).
Note: Each enclosure in the ProFibre Storage Array must have a unique
switch setting. Switch settings of 8 or 9 are not supported and
should not be used; however, if selected are treated as 7. If switch
card settings 7, 8, and 9 are used in the same system, unique FC-AL
addresses cannot be assigned to the disk drive slots.
