host-side ports hot-pluggable hub See host port. The ability to add and remove elements or devices to a system or appliance while the appliance is running and have the operating system automatically recognize the change. A communications infrastructure device to which nodes on a multi-point bus or loop are physically connected. It is used to improve the manageability of physical cables. I I/O module IDX in-band communication INFORMATION condition initialization Input/Output module intake temperature interface Input/Output module. The enclosure element that is the Fibre Channel drive enclosure interface to the host or controller. A 2-digit decimal number portion of the HSV controller termination code display that defines one of 48 locations in the Termination Code array that contains information about a specific event. The communication that uses the same communications channel as the operational data. A drive enclosure EMU condition report that may require action. This condition is for information only and does not indicate the failure of an element. All condition reports have precedence over an INFORMATION condition. A configuration step that binds the controllers together and establishes preliminary data structures on the array. Initialization also sets up the first disk group, called the default disk group, and makes the array ready for use. See I/O module. See ambient temperature. A set of protocols used between components such as cables, connectors, and signal levels. J JBOD Just a Bunch of Disks. K K Kilo. A scientific notation denoting a multiplier of one thousand (1,000). KB Kilobyte. A unit of measurement defining either storage or memory capacity. 1. For storage, a KB is a capacity of 1,000 (103) bytes of data. 2. For memory, a KB is a capacity of 1,024 (210) bytes of data. L LAN laser Last Fault View Last Termination Error Array LED License Key light emitting diode link logon Local area network. A group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area. A device that amplifies light waves and concentrates them in a narrow, very intense beam. An HSV Controller display defining the last reported fault condition. See LTEA. Light Emitting Diode. A semiconductor diode used in an electronic display that emits light when a voltage is applied to it. A visual indicator. A WWN-encoded sequence that is obtained from the license key fulfillment website. See LED. 1. A connection of ports on fibre channel devices. 2. A full duplex connection to a fabric or a simplex connection of loop devices. A procedure whereby a user or network connection is identified as being an authorized network user or participant. 304 Glossary
