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-6500 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-6500 to 60W. The DVI-D port and
the lower 15 diff pair of PMC I/O will not be accessible. Because of
the reduced power input, the use of the i7 CPU requires that the
programmable power limits be employed.
for guidance on what limits should be used in
conjunction with the installed PMC/XMC modules.
•
5-row, 5V-only legacy system. This system permits all available P2
I/O to be accessible to the XVME-6500, 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-6500, 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-6500, 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-6500.
