2.5.17.6 Precharge
Precharge is provided on the CP605 by a resistor on each signal line (PCI bus), connected to
a +1V reference voltage. If the board is configured in the System Master configuration the ref-
erence voltage is disabled.
2.5.17.7 Handle Switch
The CP605 can be delivered with or without an IPMI controller. In both cases a microswitch is
situated in the extractor handle and routed to CON13 on the board.
If the CP605 does not have an IPMI controller integrated, a local interrupt produced by the on-
board logic is generated when the extractor handle is opened. In addition, the status of the mi-
croswitch can be read in the I/O Status 2 Register, table 4-23.
If the CP605 does have an IPMI controller integrated, an IPMI event is initiated when the ex-
tractor handle is opened or closed. In addition, the status of the microswitch can be read either
in the I/O Status 2 Register, table 4-23 or via the IPMI controller.
2.5.17.8 ENUM# Interrupt
The onboard logic generates a low active interrupt signal to indicate that the board is about to
be extracted from the system or inserted into the system. This interrupt is only generated in the
peripheral master configuration. In System Master configuration the ENUM signal is an input.
2.5.17.9 Blue LED
On the CP605 without IPMI controller, a blue 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. The blue LED may also be used for general purposes. For information concern-
ing switching on and off the blue LED, refer to table 4-28, LED Control Register.
On the CP605 with IPMI controller, the blue LED can be switched on and off only by the IPMI
controller. The blue LED cannot be used for general purposes.
