Using the 1U Console Option

007-5806-004

The SGI optional 1U console is a rack-mountable unit that includes a built-in keyboard/touch-pad,

and uses a 17-inch (43-cm) LCD flat panel display of up to 1280 x 1024 pixels. The 1U console

attaches to the administrative controller server connectors or to an optional KVM switch (not

provided standard by SGI). The 1U console is basically a "dumb" VGA terminal, it cannot be used

as a workstation or loaded with any system administration program.

Note: While the 1U console is normally plugged into the administrative controller server in the

SGI ICE X system, it can also be connected to a rack leader controller server in the system for

terminal access purposes.

The 27-pound (12.27-kg) console automatically goes into sleep mode when the cover is closed.

The chassis management control network configuration of your ICE X series machine will depend

on the size of the system and the control options selected. Typically, any system with multiple

blade enclosures will be interconnected by the chassis managers in each blade enclosure.

Note: Mass storage option enclosures are not monitored by the blade enclosure's chassis manager.

Most optional mass storage enclosures have their own internal microcontrollers for monitoring

and controlling all elements of the disk array.

In all SGI ICE X series systems the system chassis management controllers communicate in the

following ways:

•

All blade enclosures within a system are polled for and provide information to the

administrative node and RLC through their chassis management controllers (CMCs). Note

that the CMCs are enlarged for clarity in Figure 2-3.

•

The CMC does the environmental management for each blade enclosure, as well as power

control, and provides an Ethernet network infrastructure for the management of the system.
