5. Appendix • 5-2 Glossary ASMA (Asus Server Management Agent) ASUS Server Management Agent is an SNMP software that provides hardware monitoring information to the Network Management Station (NMS). ASMA can report the computer fan speeds, working voltage, system temperature, and chassis intrusion events to the NMS. It can also enable or disable Automatic Server Restart (ASR) function from the NMS. Hot-Swap A hot-swap is the replacement of a connected device such as a hard drive without shutting down the computer system. LVDS (Low Voltage Differential Signaling) LVDS sends each data bit with two wires instead of one, reducing noise susceptibility and electromagnetic interference, allowing greater device connectivity and higher transmission frequencies. RAID (Redundant Array of Inexpensive Disks) RAID can be set up to provide mirroring (for fault tolerance), parity (for data guarding), or striping (for data distribution over several drives for increased performance). RJ-45 An 8-pin connector used in many computer networking devices. Female connectors are found on hardware devices, whereas male connectors are found on twisted pair cabling used to connect two networking devices. SCA (Single Connector Attachment) SCA is a technology that incorporates both power and signal into an 80-pin interface. The SCA interface is designed to facilitate hardware installation and to support hot-swapping. SCSI (Small Computer System Interface) High speed parallel interface defined by the X3T9.2 committee of the American National Standards Institute (ANSI) for connecting many peripheral devices. Ultra160 (Ultra3) A new generation of high performance SCSI technology, Ultra160 provides data transfer rates of up to 160MB/sec. UPS (Uninterruptible Power Supply) A battery system that can provide short-term power to an electronic device or computer when power fails in the building. A passive UPS only provides power. An active UPS provides power conditioning that offers protection against transient power conditions as well as short-term power outages. 5. Appendix Glossary 42 AP2300 Hardware Reference Guide
