Product Warranty A NOTE calls the user’s attention to an important point or special information in the text. This version of the M9505A/M9502A User Guide supports and describes features of the chassis firmware revision 1.3.23 (and later). This version of firmware adds features that were not available in previous firmware versions.
Page 12: Axie Chassis Description
Introduction AXIe Chassis Description AXIe Chassis Description The Keysight M9502A (2-slot) and M9505A (5-slot) AXIe chassis are modular instrument chassis fully compatible with the AXIe 1.0 specification. They allow multiple application-specific instrument modules to share a common chassis frame, power supply, cooling system, PCI Express (PCIe) Gen 2 data bus, Gigabit LAN hub, local bus for module-to-module signaling, and host PC connections.
Page 13 For the ESM and for each other installed module, appropriate control software and instrument drivers must be installed on the host PC. The M9502A/M9505A AXIe Chassis Startup Guide provides just the basics to get you started with your AXIe chassis. Provided in print with each new chassis, it can also be viewed in PDF form on the Software and Product Information CD.

Chassis Installation Verifying Operation with Modules Installed In the M9502A/M9505A AXIe Chassis Startup Guide, you should have verified basic power-on operation of the AXIe chassis and communication with the host PC. Subsequently, in this chapter you have installed instrument modules and perhaps rackmounted the chassis.
Page 46: Using The M9536A Embedded Controller Lan Ports
If you installed a Keysight M9536A Embedded Controller in the Keysight AXIe chassis (M9502A or M9505A), there are a total of three LAN ports accessible on the front panels -- two on the M9536A controller and one on the Embedded System Module (ESM).
Page 47: Recommendations
Chassis Installation This section provides overall guidance on selecting and using the M9536A LAN ports. The controller uses the Keysight IO Libraries configuration file to keep track of all instrument connections. Any change to LAN connections after running Connection Expert (adding, removing, or changing LAN cable connections) may cause a change in LAN address and therefore cause Connection Expert to lose track of instruments.
Page 48 IP addresses. With the Keysight M9536A Embedded Controller installed in the AXIe chassis, the x8 PCIe connection on the ESM module is disabled. However, the PCIe cable detect mechanism may reset the hardware when attaching a PCIe cable.
Page 49 The above figure shows the recommended LAN connections to the AXIe chassis/ESM and the M9535A. Two other possible LAN connections are shown in the following figure. Note that you may need to manually add instrument IPO addresses to Keysight Connection Expert. Keysight M9502A/M9505A AXIe Chassis User Guide...

Changes to the ESM PCIe or LAN connection are only detected as the ESM is powered up. Perform the following steps when you change either of these two connections: Within Keysight Connection Expert, delete the LAN interfaces (right click on the interface then select Delete). This causes connection Expert to forget all instrument history.

Overview The Keysight AXIe (ATCA eXtensions for Instrumentation) chassis backplanes used in the M9502A and M9505A comply with the AXIe 1.0 Base Architecture Specification. AXIe 1.0 is based on AdvancedTCA® (ATCA) architecture, expanded with several eXtensions, all of which will remain electrically compatible with standard ATCA blades.
Page 108 Zone 2 connector contacts, and devices implement different signaling schemes as defined in the AXIe specification. AXIe modules must implement electronic keying appropriate to prevent incompatible connections between AXIe and ATCA devices installed in either system environment.
