All IRUs have a chassis management controller (CMC) board installed. The following subsection
describes the basic features of the controllers:
Note: For additional information on controller commands, see the SGI UV CMC Software User
Guide (P/N 007-5636-00x).
The following list summarizes the control and monitoring functions that the CMC performs. Many
of the controller functions are common across all IRUs, however, some functions are specific to
the type of enclosure.
• Monitors individual blade status via blade BMCs
• Controls and monitors IRU fan speeds
• Reads system identification (ID) PROMs
• Monitors voltage levels and reports failures
• Monitors and controls warning LEDs
• Monitors the On/Off power process
• Provides the ability to create multiple system partitions
• Provides the ability to flash system BIOS
The SGI optional 1U console (Figure 2-3 on page 35) is a rackmountable unit that includes a
built-in keyboard/touchpad. It uses a 17-inch (43-cm) LCD flat panel display of up to 1280 x 1024
pixels. The 1U console works in concert with a 1U server (see Figure 2-4 on page 36) to provide
an "in-rack" local administrative system directly attached to the RMC.
