ILOM: Integrated Lights Out Management
Integrated Lights Out Management (ILOM) is the Service Processor used in Sun Fire X4600 servers. ILOM
enables multiple in-band and out-of-band management solutions. In-band management through the host
operating system, or platform, is enabled by IPMI and SNMP OS-resident agents. Out-of-band management is
enabled through the serial port or dedicated Ethernet. There is a command line interface (CLI) provided when
out-of-band serial port conenctivity is used. The dedicated Ethernet connectivity to out-of-band management
features include:
• Web interface
• CLI via SSH
• IPMI 2.0
• SNMP v1, v2c, and v3
ILOM Architecture
The Sun Fire X4600 server leverages the same ILOM design and part used in the Sun Fire X4100 and X4200.
ILOM is a Sun-designed Field Replaceable Unit (FRU) daughtercard. The ILOM daughtercard has the following
features:
• Motorola MPC8248 PowerPC processor
• 32-bit 266 MHz
• 16 KB 4-way associative data cache
• 16 KB 4-way associative instruction cache
• 64-bit data bus
• 66 MHz PCI bridge
• 64 MB PC-133 MHz SDRAM
• 16-bit 32 MB Flash ROM
• DVI output
• USB connections to NVIDIA nForce Professional 2200
• LPC (Low Pin Count) connection to NVIDIA nForce Professional 2200
• 10/100 MB Integrated LAN
• Three serial ports (Debug, RS485, external)
• Half-size standard PCI form factor
The ILOM daughtercard is a standalone system with no dependencies on the operating system and has
availability to physical interfaces through the connections listed above. The actual connected devices, however,
are located on the main system board. ILOM daughtercard connections include:
• DVI output port connected to the ATI Rage XL via FPGA to enable remote graphics redirection from
ILOM with a maximum VGA resolution of 1024 x 768.
