PCIe Cable Port Signals
The external PCI Express SFF-8644 cable connector supports the following signals:
•
PETpN/PETnN:
PCI Express Transmitter pairs, labeled where N is the Lane number (starting with 0); “p” is the true signal
while “n” is the complement signal.
•
PERpN/PERnN: PCI
Express Receiver pairs, labeled where N is the Lane number (starting with 0); “p” is the true signal
while “n” is the complement signal.
•
PWR: Power to support AOC and signal conditioning components within the cable assembly.
•
MGTPWR: Power supplied to the connector for cable management components that are needed while the link is not
active. This needs to be active if the subsystem has power.
•
CBLPRSNT#: Cable present detect, an active-low signal pulled-down by the cable when it is inserted into the MXP909
module connector.
•
CADDR: Signal used to configure the upstream cable management device address.
•
CINT#: Signal asserted by the cable assembly to indicate a need for service via the CMI controller.
•
CMISDA: Management interface data line. Used for both initial link setup and sideband messages when used with CMI
compliant cables.
•
CMISCL: Management interface clock line. Used for both initial link setup and sideband messages when used with CMI
compliant cables.
