2.5.10 SW2, Geographic Address
SW2 allows user to set the CPCI-6115's Geographic Address when installed in a chassis that
does not supply this information. Setting ON grounds signal, OFF pulls up.
2.6 Operating Modes
An CPCI-6115 configured for standalone mode should not be installed in a chassis with a
system slot controller board. This results in unpredictable system operation. In this mode, the
CPCI-6115 cannot communicate over the CompactPCI backplane.
In the standalone mode, a jumper must be set (J9) on the CPCI-6115 to obtain clock signals
from other on-board devices. This routes an on-board PCI clock to the 21555 primary side clock
input and allows the CPCI-6115 to operate in a chassis with no system slot controller board
installed.
An CPCI-6115 configured for the standard operating mode must be used in a chassis with a
system slot board which provides the clock and arbitration signals to the CPCI-6115.
The chassis must provide +5 V, +3.3 V and VIO to the CPCI-6115, and the BD_SEL pin (P1-
D15) in the chassis must be grounded.
2.7 Installing Hardware
The following sections discuss the placement of PMC mezzanine cards on the CPCI-6115
baseboard and the installation of the complete CPCI-6115 assembly into a CompactPCI
chassis. Before installing the CPCI-6115, ensure that all header jumpers are configured as
desired according to the previous sections of this chapter.
It is critical that two prerequisite steps be performed prior to installing your board into the
CompactPCI backplane to prevent possible backplane pin damage.
1. Visually inspect the board connectors to ensure they are not damaged by previous
insertions or accidental mishandling. If any board connector damage is observed, do not
install board into the backplane. This may cause a bent pin on the connector, resulting in
an expensive repair.
2. Visually inspect the backplane pins for any bent pins from previous board installations in
the slot where the board will be installed.
