POWER INDICATORS

LEDs provide a convenient visual check for +5V, -5V, +12V and +3.3V power connection and status.

CAUTION: When the power indicators are on do not install or remove the SBC or any option card from the BP3/2/4/4 backplane.

POWER CONNECTORS

The BP3/16-64 backplane is available with a vertical AT or ATX power connector. The power connection for +3.3V is available through a 12-pin .156 MTA connector or the optional ATX connector.

Additional power capacity is available through a .156 MTA connector.  Optional extended-current connectors are available to provide additional power capacity for power-intensive applications -- up to 60 Amps of +5V plus 60 Amps of +3.3V.

MISCELLANEOUS BACKPLANE INFORMATION

PCI-TO-PCI BRIDGE
The PCI-to-PCI bridge supports the PCI 2.1 specification. This bridge allows PCI Local Buses to extend the electrical loading limits of a single PCI Bus and to operate independently, allowing for communication within the same bus even if the other PCI Buses are busy. The BP3/16-64 backplane has bus mastering capabilities on all 16 PCI Local Bus slots.

PCI LOCAL BUS SLOTS
Provides 16 PCI Local Bus slots. All PCI Slots are 33 MHz, and support 64 bit and 32 bit Standard PCI Local Bus option cards.
