Each cable is labeled with a cable number, and each cable's point (head and tail) is also numbered, because each cable can only fit one way and is not interchangeable. For a list of all the cables and their respective connectors, please refer to the power cable list in this section. The figure below illustrates the power cables that connect to the system board and the SCSI backplane board.

Other than the size, the major improvement of the Slot 2 processor is at the L2 cache. Pentium II Xeon processors access the L2 cache at full clock speed, 400 MHz or 450 MHz, whereas a Slot 1 processor accesses the L2 at only half the CPU's clock speed. Thus, Slot 2 processor significantly boost performance and speed. Here are some of the other features of the Pentium II Xeon processor: · 0. 25 micron P6 microarchitecture core System Boards 3-7 · · 100 MHz System Bus and 60ns buffered EDO memory support New System management features via System Management bus (Smbus) The system board comes with four Slot 2 CPU sockets and their respective retention mechanism to secure the CPU. Installing an Intel Pentium II Xeon processor Follow these steps to install a Pentium II Xeon processor: 1. Attach the fansink module to the Pentium II Xeon processor and secure it with four screws. 2. [. . . ] Provide visualization interface and statistics tools. rd ASM Pro also detect, record, and recover hardware problems during POST (Power-On Self Test). · · · Checks the main board and housing status when system is first powered. Recover critical events by isolating faulty CPU and memory. Record all events into NVRAM. These features are designed primarily for server supervisors and management information system (MIS) personnel to help them detect errors or potential trouble spots in their network servers through a centralized management console. Diagnostics and Utilities 5-1 ASM Pro consists of two major parts: · · ASM-Station - a Windows-based monitoring station that communicates with the ASM-Agents. [. . . ]
