Planning for the Dedicated OSM or TSM LAN
The dedicated LAN connects to the Ethernet ports on PMF CRUs located in group 01.
See Figure 2-12. This LAN includes only components specified by HP and must not
include routers or bridges.
A dedicated LAN can include all the nodes in a ServerNet cluster, provided all the
nodes are within the reach of the Ethernet cables. Such a LAN is highly useful. You
can use it to perform system console operations for every node in the ServerNet
cluster from any system console on the LAN. System console operations include
establishing a low-level link connection, managing incident reports (IRs), and dialing
out information to a service provider.
