I/O multifunction (IOMF) 2 CRU
cable and supplies power to the components within the IOMF CRU as well as 
redundantly to the disk drives, SCSI terminators, and ServerNet adapters in that 
enclosure. The IOMF CRU contains a power supply, a service processor (SP), a 
ServerNet router, an Ethernet controller, an external ServerNet port, and three SCSI 
ServerNet addressable controllers (S-SACs) in a single unit. (2) A collective term for 
both IOMF CRUs and IOMF 2 CRUs when a distinction between the two types of 
CRUs is not required.
I/O multifunction (IOMF) 2 CRU. An HP NonStop™ S-series customer-replaceable unit 
(CRU) that connects an I/O enclosure to a processor enclosure through a ServerNet 
cable and supplies power to the components within the IOMF 2 CRU as well as 
redundantly to the disk drives, SCSI terminators, and ServerNet adapters in that 
enclosure. The IOMF 2 CRU contains a power supply, a service processor (SP), a 
ServerNet router 2, an Ethernet controller, three configurable ServerNet ports, and 
three SCSI ServerNet addressable controllers (S-SACs) in a single unit. IOMF 2 
CRUs are supported on G06.10 and later software release version updates (RVUs).
IOP. See input/output process (IOP).
IP. See Internet protocol (IP).
IP address. An address that uniquely identifies a specific host system within a network to 
the Internet protocol (IP). An IP address consists of two parts: a network address, 
which identifies the network, and a local address, which identifies the host within the 
network. IP routes data between source and destination IP addresses.
iPAQ Desktop. An Internet-based computing model and business PC used for Internet 
access, mainstream computing, and running the Windows 2000 Professional operating 
system. The iPAQ Desktop is designed to reduce hardware and software conflicts; it 
eliminates Industry Standard Architecture (ISA)/Peripheral Component Interconnect 
(PCI) slots and uses Universal Serial Bus (USB) ports with the Windows 2000 or 
Windows ME operating system.
IPC. See interprocessor communications (IPC).
IPU. See instruction processing unit (IPU).
ISO. International Organization for Standardization. ISO is an international body that drafts, 
discusses, proposes, and specifies standards for network protocols. ISO is best known 
for its seven-layer reference model that describes the conceptual organization of 
protocols.
ISO is sometimes called the “International Standards Organization”; although ISO is 
the official abbreviation, it does not correspond to the organization’s name in any 
language. 
ISO 646. An ISO standard for representing characters in languages based on the Roman 
alphabet. Like ASCII, ISO 646 uses only 7 bits of each 8-bit byte to represent data. 
Contrast with ISO 8859.
