3.1.6 VME Configuration Switch SW7
Table 3.1.f summarizes the functions, settings, and descriptions for dip switch
SW7.

VME CSR address: when the switch is
closed, the corresponding address is set to
‘1’.
(all OFF by default)
SW7 is used to configure the 64K CR/CSR window offset mapping when
VME64x mode is not used. When VME64x mode is used, the value of SW7 is
not used, and the CR/CSR register is mapped using the geographic address
provided by the backplane.
3.2 Power Supply and Management
3.2.1 Power Options
The XVME-6700A can be used in any of the following VMEbus systems, with
the associated caveats:
•
3-row, 5V-only legacy system. This system will limit the P2 I/O and
the incoming power to the XVME-6700A to 60W. The DVI-D port
and the lower 15 diff pair of PMC I/O will not be accessible.
•
5-row, 5V-only legacy system. This system permits all available P2
I/O to be accessible to the XVME-6700A, but the lack of a 3.3V
power supply means that the available 90W of 5V power also feeds
the 3.3V needs of the XVME-6700A, as well as those of any
attached PMC/XMC modules.
•
5-row, 5V + 3.3V VME64x system. This system permits all available
P2 I/O to be accessible to the XVME-6700A, as well as allows for the
maximum available power from the backplane (90W from 5V and
66W from 3.3V). This is the recommended system for the XVME-
6700A.
3.2.2 Power Management
The XVME-6700A module uses the Advanced Configuration and Power
Interface (ACPI) 3.0 standard to provide user-managed power via the
operating system.
3.2.2.1 ACPI System States
There are only two ACPI
“Module States”
supported by the XVME-6700A:
•
G0/S0: Fully operational; the main memory is being used for all work.
