CP6003-SA
2.10.11.2 Board Functionality when Installed in Peripheral Slot (Passive Mode)
In a peripheral slot, the board receives power but does not communicate on the CompactPCI
bus; all CompactPCI signals are isolated.
In this configuration, the communication is achieved via the two Gigabit Ethernet ports as de-
fined in the PICMG 2.16 specification.
2.10.11.3 Packet Switching Backplane (PICMG 2.16)
The CP6003-SA supports two Gigabit Ethernet ports on the J3 connector in accordance with
the CompactPCI Packet Switching Backplane Specification PICMG 2.16. The two ports are
connected in the chassis via the CompactPCI Packet Switching Backplane to the Fabric slots
"A" and "B".
The PICMG 2.16 feature can be used in the system slot and in the peripheral slot as well.
2.10.11.4 Hot Swap Support
To ensure that a board may be removed and replaced in a working bus without disturbing the
system, the following additional features are required:
• Power ramping
• Precharge
• Hot swap control and status register bits
• Automatic interrupt generation whenever a board is about to be removed or replaced
• A Hot Swap LED to indicate that the board may be safely removed
2.10.11.5 Power Ramping
On the CP6003-SA a special hot swap controller is used to ramp up the onboard supply volt-
age. This is done to avoid transients on the +3.3V, +5V, +12V and -12V power supplies from
the hot swap system. When the power supply is stable, the hot swap controller generates an
onboard reset to put the board into a definite state.
2.10.11.6 Precharge
Precharge is provided on the CP6003-SA by a resistor on each signal line (PCI bus) connected
to a +1V reference voltage.
2.10.11.7 Handle Switch
A microswitch is situated in the extractor handle. The status of the handle is included in the on-
board logic. The microswitch is connected to the onboard connector J13.
2.10.11.8 ENUM# Interrupt
If the board is operated in the system slot, the ENUM signal is an input.
2.10.11.9 Hot Swap LED
The blue HS LED can be switched on or off by software. It may be used, for example, to indicate
that the shutdown process is finished and the board is ready for extraction.
