The blade PC image PXE boot process

During the blade PC PXE boot process, the PXE server listens to communication between the blade PC
and the DHCP server, and then sends its IP address to the blade PC at the right moment. Once the blade
PC begins to boot, it knows the IP address to use to communicate with the PXE server.
DHCP Server

1. Blade PC requests (Discover) a new IP address from the DHCP server (UDP Port 68 to 67).
2. DHCP Server responds (Offer) by sending an available IP address to the blade PC (UDP Port 67 to
68).
3. PXE Server listens for DHCP Discover and Offer, and then sends its IP address to the blade PC (UDP
Port 67 to 68).
4. Blade PC sends confirmation message to DHCP Server (UDP Port 68 to 67).
5. DHCP Server sends acknowledgement of confirmation to client, and then provides additional informa-
tion if necessary (UDP Port 67 to 68).

CCI solution component dependencies

Each reference design includes the components that comprise the CCI solution. You can configure and
deploy CCI components in a variety of ways to satisfy customer-specific requirements. The need to sepa-
rate components is typically deployment driven. The CCI solution is flexible enough to meet specific cus-
tomer requirements, but there are some dependencies which you must consider during the design phase.
Each section identifies components and their dependencies.
