The laser system bus (LSB) chassis (BA700- AA) contains the CPU and memory boards, along with an I/O port controller (IOP) that multiplexes to support up to four XMI I/O chassis. The LSB chassis includes a 48 Vdc power supply and a blower assembly to move the cooling air. In addition, the chassis has its own circuit breaker and power cord that requires a single-phase, 200-240 Vac (nominal), 50-60 Hz power source. The LSB chassis has a power status indicator as part of the operator control panel. The extended memory interface (XMI) chassis (BA601-AC) mounts above the LSB chassis in the cabinet and can accept up to 12 XMI technology I/O modules. Other rackmountable I/O chassis for modules using different I/O bus types may be added to this product family in the future. The XMI chassis also accommodates up to five quad and three dual I/O panels. The XMI chassis includes six power supply modules and fans for moving the cooling air. The XMI chassis has its own circuit breaker and power cord that requires a single-phase, 200-240 Vac (nominal), 50-60 Hz power source. The XMI chassis also has a power status indicator as part of the control panel. In an H9702 cabinet, a power controller is mounted behind each LSB chassis to allow the connection of both chassis to an external source of 200-240 Vac (nominal), and also to sequence the power application and removal to this system. The LSB and XMI chassis are interconnected with a flat ribbon cable between the I/O port controller (IOP) in the LSB chassis and the XMI backplane in the XMI chassis. Introduction 1-1 Introduction Figure 1-1 Two DEC 7000 AXP and VAX 7000 Systems in an H9702 Cabinet 1-2 Introduction Introduction 1.2 Laser System Bus (BA700-AA) Chassis The LSB (BA700-AA) chassis, shown in Figure 1-2, contains a card cage, a 48 Vdc power supply, a control panel, and a blower assembly. The following sections describe the basic components of the LSB chassis. Figure 1-2 LSB (BA700-AA) Chassis with Covers Removed Introduction 1-3 Introduction 1.2.1 LSB Chassis Card Cage The LSB chassis card cage contains five slots. One slot is reserved for the I/O port controller (IOP) module and the other four slots are available for either CPU or memory modules. The system must have at least an IOP module, one CPU module, and one memory module in order to function. Rackmount DEC 7000 AXP and VAX 7000 systems can range from a single CPU with three memory modules to three CPUs with a single memory module. Table 1-1 contains a list of the different types of modules that can be installed in the rackmount DEC 7000 AXP and VAX 7000 systems, and a description of each.

The LSB chassis control panel consists of three push-button switches with integral LED indicators and three separate LED indicators. Figure 1-3 LSB Chassis Control Panel Introduction 1-5 Introduction Table 1-2 lists the three push-button switches and describes their functions. Table 1-2 LSB Control Panel Push-button Switches ------------------------------------------------------------ Switch Position LED Status /Color Description ------------------------------------------------------------ On/Off Out Off The 48 Vdc power supply is turned off. In On (Green) The 48 Vdc power supply is turned on and 48 Vdc is present. Secure Out Off Indicates to the console firmware that certain privileged console commands are allowed. In On (Green) Indicates to the console firmware that certain privileged console commands are not allowed. Restart (Momentary switch) Out Off The system restart signal is not being asserted. In On (Red) The system restart signal is being asserted. ------------------------------------------------------------ The LSB control panel also includes three status LED indicators. Table 1-3 lists these LEDs and describes their functions. Table 1-3 LSB Control Panel Status LED Indicators ------------------------------------------------------------ LED Name/Color Function ------------------------------------------------------------ Power (Green) Lit when the 48 Vdc power supply is on and the output is within specifications. If not lit after the On/Off switch is depressed, the power supply has detected an overvoltage or overcurrent condition. Run (Green) Lit when console mode is terminated and system program execution begins. Not lit during power sequencing and when in console mode. Fault (Amber) Blinks at a slow 2-second rate during the power-up sequence and at a fast .5-second rate during the power-down sequence. After the power-up sequence, it stays lit until all LSB and I/O modules have passed self-test, and then goes out. Being lit during normal operation indicates a blower failure, an LSB or I/O module not passing self-test, or a power supply fault. ------------------------------------------------------------ 1-6 Introduction Introduction 1.2.3 LSB Chassis Power Supply A 48 Vdc power supply is located on the left side of the LSB chassis. This power supply provides 48 Vdc to the control panel, the LSB backplane, and the chassis blower.
