Planning for LAN Communications
This section describes requirements and considerations for configuring local area
networks (LANs) for NonStop S-series servers.
Except for the disk drives and tape drives connected to SCSI ports on PMF CRUs and
IOMF CRUs, peripheral devices connect to a server through a local area network
(LAN).
Dedicated LANs
NonStop S-series servers require a dedicated LAN for each of these sets of
components:
•
Components related to OSM or TSM
•
Components related to SWAN concentrators
A dedicated LAN can connect only to components specified by HP. No other access to
the LAN is permitted.
Dedicated Service LAN for OSM or TSM
The dedicated service LAN for use by OSM or TSM can connect only to system
consoles, the Ethernet ports on the PMF CRUs in group 01, Ethernet switches or hubs,
and maintenance switches provided by HP.

Note. System consoles can also be connected to a secure operations LAN. However, the
dedicated LAN is required for installation and use of the complete set of OSM or TSM client
applications (the Low-Level Link and Notification Director applications cannot be used on a
system console connected to a secure operations LAN). See Secure Operations LANs
on
page 11-2.
