System Connections Overview

Connecting to the UV System Control Network

007-5832-002
You can monitor and interact with your SGI UV 2000 server from the following sources:
• Using the SGI 1U rackmount console option you can connect directly to the system
management node (SMN) for basic monitoring and administration of the system. See "1U
Console Option" in Chapter 2 for more information; SLES 11 or later is required.
• A PC or workstation on the local area network can connect to the SMN's external ethernet
port and set up remote console sessions or display GUI objects from the SGI Management
Center interface.
• A serial console display can be plugged into the CMC at the rear of IRU 001. You can also
monitor IRU information and system operational status from other IRUs that are connected
to IRU 001.
These console connections enable you to view the status and error messages generated by
the chassis management controllers in your SGI UV 2000 rack. For example, you can
monitor error messages that warn of power or temperature values that are out of tolerance.
See the section "1U Console Option" in Chapter 2, for additional information.
The following subsections describe the options for establishing and using communication
connections to work with your SGI UV 2000 system.
The ethernet connection is the preferred method of accessing the system console.
Administrators can perform one of the following options for connectivity:
• If the SMN is plugged into the customer LAN, connect to the SMN (SSH w/ X11
Forwarding) and start the SGI Management Center remotely.
• An in-rack system console can be directly connected to the system management node via
VGA and PS2, see Figure 1-5 on page 8. You can then log into the SMN and perform
system administration either through CLI commands or via the SGI Management Center
interface.
Note that the CMC is factory set to DHCP mode and thus has no fixed IP address and cannot be
accessed until an IP address is established. See the subsection "Using DHCP to Establish an IP
Address" on page 10 for more information on this topic.
