ATCA-9405 Installation and Use (6806800M71G) 102
The physical layer device (PHY) of the configured ports attempt to bring up the links, which
includes link training process, link initialization, and automatic link width negotiation.
The following table lists the port configuration:
The SP has the role of PCIe root complex, thus Port 0 is configured as default upstream port.
6.3 Hot Plug Support
ATCA-9405 supports software controlled power-down and power-on sequence for the two PP
units including memory, Gigabit Ethernet PHY, TCAM module, and all external interfaces. This
is used to reduce power consumption of the blade, when application does not need full
computing performance of both PPs.
The ports that are neither configured nor enabled are invisible to the software.
