M9506A 5-Slot AXIe ChassisStartup GuideIntroductionThe Keysight M9506A AXIe chassis is a modular instrument chassis fullycompatible with the AXIe Wide PCIe specification. It allows multipleapplication-specific instrument modules to share a common chassis frame,power supply, cooling system, PCI Express (PCIe) x16 Generation (Gen) 3backplane, Gigabit LAN hub, local bus for module-to-module signaling, and hostPC connections. The full rack chassis provides five general purpose peripheralslots that accept 1U AXIe instrument modules.Additional features include:– Up to 300 W per slot power– Five AXIe Wide compliant slots– PCIe x16 Gen 3 Backplane allows module to module communication– Default PCIe configuration merges both cable ports to one Gen 3 x16 PCIeCable Port.– Open AXIe Zone 3 for custom use (cable access, analog backplane, etc.)– Thunderbolt™ 3 Connection Port 1– Cascaded PCIe for multiple chassis systems– Parallel and Star Triggering– Push-pull fan system for quieter operationThe chassis includes a half-height Embedded System Module (ESM) thatmanages chassis functions. The ESM provides all ATCA (AdvancedTelecommunications Computing Architecture) shelf manager functions, plusthese AXIe extensions:– Host PC connectivity (Gen 3 PCIe x8/x16, Thunderbolt 3, Ethernet)– Sources timing signals (CLK100, SYNC, and FCLK)– Routes STRIG (Star Trigger) to instruments through the backplane– Two bi-directional trigger access ports route trigger signals through to thebackplane parallel trigger bus and star triggers (STRIG) to each slot– Provides backplane PCIe and Ethernet communication between modulesOther than a power button/status light (on the ESM), all monitoring, control, andcommunication with the chassis requires a host PC. This can be an embedded PCspecifically designed for use in an AXIe chassis (such as the Keysight M9537A) orremote (a rackmount, desktop, or laptop) PC.The Gen 3 PCIe Cable Interface ports provides up to a 8GB/s (theoretical) for Gen3 x8 and 16 GB/s (theoretical) for Gen 3 x16. The Thunderbolt 3 port provides aGen 3 x4 link with up to 4 GB/s (theoretical) bandwidth.1 Thunderbolt ™ is the brand name of an interface standard developed by Intel (in conjunction with Apple) thatallows connection of external peripherals to a computer. Thunderbolt 3 specification provides Gen 3 PCIExpress (PCIe), DisplayPort, and DC power in one USB-C compatible cable; only PCIe is supported on theM9506A. Charging devices such as laptop computers over Thunderbolt 3 is not supported on the M9506A.
