Installing Modules 2
The chassis includes a half-height Embedded System Module (ESM) that
manages chassis functions. The ESM provides all ATCA (Advanced
Telecommunications Computing Architecture) shelf manager functions,
plus these 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
the backplane parallel trigger bus and star triggers (STRIG) to each slot
• Provides backplane PCIe and Ethernet communication between
modules
Other than a power button/status light (on the ESM), all monitoring,
control, and communication with the chassis requires a host PC. This can
be an embedded PC specifically designed for use in an AXIe chassis (such
as the Keysight M9537A) or remote (a rackmount, desktop, or laptop) PC.
The Gen 3 PCIe Cable Interface ports provides up to a 8GB/s (theoretical)
for Gen 3 x8 and 16 GB/s (theoretical) for Gen 3 x16. The Thunderbolt 3
port provides a Gen 3 x4 link with up to 4 GB/s (theoretical) bandwidth.
Refer to the Keysight M9506A 5-Slot AXIe Chassis Startup Guide to get
detailed information about the AXIe chassis.
