Keysight M9046A 18-Slot PXIe Chassis User Guide Power Supply Operation The Primary Power Module (PPM) provides a 24V output voltage that is converted down to 12V and 3.3V for each individual slot, while the 5V is shared across slots 1 through 4, and -12V is shared across Slots 2 through 4 listed below.
Page 49: Power Supply Capacity
The total amount of power available to modules depends on the AC voltage. For example, for the M9046A chassis at low line AC (100/120V), the total power drawn from the PPM is 887.5 W available to all modules; at high line AC (220/240V), the total power drawn from the PPM is 1675 W.

Overview of chassis cooling The key points regarding chassis cooling are: – For the M9046A, three 210 cubic feet per minute (CFM) fans, provide a total airflow of up to 630CFM. These fans are mounted on the chassis rear panel. They pull air from the rear panel and push air through the chassis.
Page 61 (obstruction, fan failed etc.) and correct it before powering on the chassis. – The M9046A chassis have eight temperature sensors mounted above of the modules to monitor the air flow temperature downstream from the modules. These temperatures can be read using the SFP or programmatically.
Page 62: Monitoring The Chassis Temperature
Chassis Cooling and Rack Mounting Monitoring the Chassis Temperature Keysight PXIe chassis allows you to monitor each of the air flow exit temperature sensors using either the SFP, the IVI drivers, or the LabVIEW driver. In addition, the SFP and IVI drivers can be used to set an upper temperature threshold such that an alarm will be generated if any temperature sensor reports a temperature above the specified threshold.

Refer to the IVI help system for information on performing self test programmatically. As noted above, executing self test programmatically is very similar to the SFP implementation of self test. Keysight M9046A PXIe Chassis User Guide...
Page 114: Self Test Codes And Messages
“Chassis fan speed selector switch is in HIGH position, but one or more fans not operating at maximum speed.” “Chassis fans are operating at dissimilar speeds.” “Chassis fan AUTO speed control is not functioning properly.” “IO failure during self test. If problem persists, contact Keysight Technical Support.” unused unused “Reading from non-volatile chassis memory failed.”...
Page 115 Error Code ”Chassis Manager operating on backup (read-only) firmware image. See Keysight Technical Support.” ”Chassis Manager firmware was updated since power-up. Power cycle the chassis and reboot system controller.” ”Chassis memory structure corrupted. Run IVI driver (or SFP utility) Reset command, and then rerun self test to validate.”...
Page 116 Known chassis NV memory access issue, you must power cycle to restore proper chassis operation. M9046A is self identifying as an M9046A. Fix by running PCIe Switch Fabric Configuration utility. Previous firmware update on Chassis Manager Firmware is not complete, please rerun firmware update again to complete the operation.

If the fan LED blinks for 6 times, the top fan #6 is the culprit. (applicable if the top fan tray is installed) If the fan LED blinks for 7 times, the top fan #7 is the culprit. (applicable if the top fan tray is installed) - Repeat Keysight M9046A PXIe Chassis User Guide...
Page 119 The only way to exit from this fault condition is to cycle AC power. AC power needs to be removed for at least 10s to allow the standby voltage to bleed down to 0V so that the chassis controller is shut off. Keysight M9046A PXIe Chassis User Guide...

- On Continuously: All fans running above factory default/user-defined limit. - Blink: One or more fans running below factory default/user-defined limit. Temperature LED - Off: Chassis temperature OK. - Blink: One or more temperature sensors above factory default/user-defined limit. Keysight M9046A PXIe Chassis User Guide...
Page 121 If all 3 LEDs are blinking at the rate of 10 seconds On and 1 second Off, the Serial Peripheral Interface between the power fan control board and chassis FPGA is broken. Contact Keysight at keysight.com/find/contactus to have your chassis sent to the local service center for repair.
