3.2.6 CompactPCI interface
The CPC507 module has a flexible CompactPCI interface. If the board is installed into the system
slot, then the PCIE-PCI bridge operates in the PCI bus master mode, and if the board is installed
into the peripheral sl
ot, the bridge operates in the “non-transparent” mode.
3.2.6.1 Operation in system slot (System Master)
Being in the system slot, the CPC507 module can exchange information with all other CompactPCI
boards through the 64-bit Pericom PI7C9X130 PCIE-PCI reversible bridge operating at 33/66 MHz.
The module supports a maximum of 7 x CompactPCI devices via a passive backplane (for 33
MHz), 6 x devices can operate in BUS Master Mode.
The module supports 3.3V and 5V PCI bus levels.
The module fully complies with the PCI Local Bus Specification Rev. 3.0.
3.2.6.2 Operation in peripheral slot (Slave Mode)
In the peripheral slot, the bridge
operates in the “non-transparent” mode, while there is a possibility
of data exchange via the PCI bus
3.2.6.3 Packet Switching Backplane PICMG 2.16
A Gigabit Ethernet port is available on the XS21 CPC507 connector in accordance with the PICMG
specification for CompactPCI Packet Switching Backplane Specification PICMG 2.16, version 1.0.
These two network nodes (Gigabit Ethernet 1 and 2) are connected in the chassis through the
CompactPCI Packet Switching Backplane with
“A” and “B” special-purpose fabric slots,
respectively.
These properties of the PICMG 2.16 can be used in both the system slot and the peripheral slot.
3.2.6.4 Switch in the handle
The microswitch is located in the lower handle of the CPC507 front panel and it is connected to
XP1 on the board. Opening the handle starts the module shutdown procedure. A short-time
pressing on the microswitch makes the board to reset. The switch operation mode can be changed
in BIOS Setup.
3.2.6.5 Power Mode LED (SYS)
The red and blue SYS LED on the front panel of the CPC507 is used to indicate the power supply
mode of the module, see the table "State of the SYS LED of the CPC507 module" (Table 3-8).
