2.3 Cabling for the Administration Network

For server blades, the administration network is created and connected through ProCurve model 2800 series switches. One switch is designated as the root administration switch and that switch can be connected to multiple branch administration switches, if required.

NIC1 on each server blade is dedicated as the connection to the administration network. NIC1 of all server blades connects to interconnect bay 1 on the enclosure.

The entire administration network is formed by connecting the device (either a switch or a pass-thru module) in interconnect bay 1 of each enclosure to one of the ProCurve administration network switches.

Non-blade server nodes must also be connected to the administration network. See Chapter 3 (page 45) to determine which port on the node is used for the administration network; the port you use depends on your particular hardware model.

Figure 2-4illustrates the connections that form the administration network.
