Ethernet Port Connections on the Head Node
Table 3-2 lists the Ethernet port connections on the head node based on the type of interconnect in use. Use
this information to determine the appropriate connections to make for the external network connection on
the head node.

1.1. Physical onboard Port #1 is always the connection to the
Administration Network.
Physical onboard Port #1 is always the connection to the
Administration Network.
2. 2.Physical onboard Port #2 is the connection to the interconnect. Physical onboard Port #2 is available for an external
connection if needed (except if the port is 10/100, then it is
unused).
3. Add-on NIC card #1 is available as an external connection.
3. Add-on NIC card #1 is available for an external connection
if Port #2 is 10/100.
General Hardware Preparations
Make the following hardware preparations on all cluster platform types if you have not already done so:
1. The connection of nodes to ProCurve switch ports is important for the automatic discovery process.
Ensure that all nodes are connected as described in “Making Node and Switch Connections” (page
19).
2. Ensure that switches are configured to obtain IP addresses using DHCP. For more information on how
to do this, see the documents that came with the ProCurve hardware, which are also available at:
http://www.hp.com/go/hpprocurve
3. Ensure that any nodes connected to a Lustre® file system server are on their own Gigabit Ethernet
switch.
4. Ensure that all nodes have the correct firmware revision and that all nodes in the system are at the same
firmware revision. (See “Firmware Requirements and Dependencies” (page 31).) The hardware
preparation steps shown in this chapter apply only if the nodes are running the correct firmware revision;
otherwise, menus and options might be different.
Proceed to one of the following sections to make additional hardware preparations depending upon your
cluster platform:
• Preparing the Hardware for CP3000 Systems (page 33)
• Preparing the Hardware for CP4000 Systems (page 39)
• Preparing the Hardware for CP6000 Systems (page 48)
