NonStop NS1200 Planning Guide

Fault-Tolerant Configuration
• 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.
For an example of a fault-tolerant LAN configuration with two maintenance switches, see “Primary
and Backup System Consoles Managing One System” (page 75).
IP Addresses
Integrity NonStop NS1200 servers require Internet protocol (IP) addresses for these components
that are connected to the dedicated service LAN:
• VIO enclosure logic boards
• Maintenance switches
• System consoles
• Blade iLOs
• UPSs (optional)
NOTE: As of the H06.12 RVU, Blade iLO IP addresses are configured using DHCP. If you
require static Blade iLO IP addresses, use the IP addresses listed below for this component.
These components have default IP addresses that are preconfigured at the factory. You must
change these preconfigured IP addresses to addresses appropriate for the LAN environment:
