NonStop NS14000 Planning Guide (H06.10+)

NOTE: System consoles require a dedicated LAN for installation and use of the complete set
of OSM client applications.
Basic Configuration
A basic dedicated service LAN that does not provide a fault-tolerant configuration requires
connection of these components to the ProCurve 2524 maintenance switch installed in the modular
cabinet:
• One connection for each system console running OSM.
• One connection for each VIO enclosure.
• At least one connection to an Ethernet port in each VIO enclosure. You must have these
connections to use the OSM Service Connection and OSM Notification Director.
• (Optional) one connection to one or more uninterruptible power sources (UPSs).
Fault-Tolerant Configuration
You can configure the dedicated service LAN as described in the OSM Migration and Configuration
Guide. HP recommends that you use a fault-tolerant LAN configuration. A fault-tolerant
configuration includes these connections to two maintenance switches:
• Connect one system console to each maintenance switch.
• Connect the VIO enclosure for the X fabric to one of the maintenance switches and the VIO
enclosure for the Y fabric to the other maintenance switch.
• Connect one Ethernet port in each VIO enclosure to each maintenance switch.
• Connect one maintenance switch to an HP extension bar that is powered by the UPS. HP
extension bars are installed in place of a PDU on the rear right side of the modular cabinet.
CAUTION: To avoid possible conflicts on the LAN:
If the configuration includes two maintenance switches, install and configure one switch
completely, including assigning its IP address, before you install the other.
Only one connection between the maintenance switches is permitted. More than one
connection overloads network traffic, rendering the dedicated service LAN unusable.
If VIO enclosures will have static IP addresses, configure one completely, including assigning
the IP address, before you configure the other.
