M9514A and M9521A AXIe 14-Slot Chassis and AXIe System Module

Data Sheets

The M9514A AXIe chassis and M9521A AXIe System Module (ASM) are fully compatible with the AXIe 1.0 and 2.0 specifications. The chassis provides 13 instrument modules slots plus an AXIe system slot while the ASM is used with the chassis to provide the necessary system functions. The ASM provides Gigabit LAN and Gen 2 x8 PCIe® interfaces for connecting the chassis to an external controller. The chassis is designed to be easily maintained. The power supplies and fan trays can be removed while the chassis remains in the rack

Applications

•  Aerospace and defense

•  Computation

•  Communications

•  Electronics test

•  Semiconductor testing

•   High-energy physics

Features

•  AXIe 1.0 (architecture) and 2.0 (software) compliant

•  Available AXIe System Module with Gen 2 PCIe x8 and Gigabit LAN interfaces for connecting to host computer

•  Keysight Technologies, Inc. exclusive, built-in MultiFrame synchronization for multi-chassis systems

•  62 differential local bus lines provide very large data path between adjacent modules

•  High power with 200W cooling per slot

•  Front and rear removable fan trays

Customer values

•  AXIe chassis provides a high-performance platform to compliment PXI based systems

•  The 14-slot chassis can accommodate more AXIe modules when the application requires a larger system

•  With the innovative cooling design, no additional rack space is required to meet cooling specifications while providing adequate cooling for a large number of high-power modules

•  The front panel x8 PCIe links on the ASM enable very large systems (up to three 14-slot AXIe chassis can be inter-connected) or allow AXIe and PXIe chassis to be combined in a single system

M9514A hardware overview                                                                               Backplane configuration

The AXIe backplane in the Keysight M9514A include all of the following AXIe backplane lines:

• Timing and triggering signals including: 100 MHz clock, 100 MHz PCIe clock (FCLK), point-to-point star trigger from the system slot (SYNC), bi-directional point-to-point star trigger (STRIG), and 12 signal parallel trigger bus (TRIG)

• Distributed PCIe data fabric (Gen 2 x4 to each slot)

• Distributed gigabit Ethernet LAN to each slot

• 62-pair local bus for adjacent module signaling or data transfer (AXIe only requires 18 pairs)

• DC power rail (nominally -52 VDC)

• Intelligent Platform Management Bus (IPMB) for chassis control, including module power-up

Chassis shelf manager

The chassis shelf manager provides intelligent control of the M9514A including control of the chassis cooling fans and managing the chassis power-up sequence. This ensures there is sufficient power/cooling for each module.

Innovative cooling

The AXIe chassis utilizes a “push-pull” cooling design that provides a high volume of cooling air with acoustical emissions which are lower than a chassis with only a push or pull design. Fans in the front of the chassis bring in cool air from outside the rack and fans in the back of chassis pull the warm air out. Auto-speed fans are used to ensure adequate cooling as module temperatures change.

Lower maintenance costs

The chassis were designed to reduce maintenance costs. In addition, the power supplies, air filters, and fan trays can be removed while the chassis is mounted in a rack, allowing the chassis to be serviced while keeping DUT cabling in place.
