ELECTRICAL SPECIFICATIONS
3.3 VDC Output
The PMC supports a 3.3 V power output from the edge connector to support the backplane FRU device. This output supports 3.3 V operation at up to
5 mA.
PMC Kill
PMC Kill is a mate-first, break-last pin to initiate connection to the PSUs through the backplane to safely connect the PMC. It is pulled low to the
backplane.
PCB Revision
The PMC supports reading of a 3-bit PCB revision using GPIOs on the AST2600 processor. Revisions are set using strapping resistors. The
purpose of the ID bits is to communicate to firmware the identity of the PMC in the event that different PCB revisions require different firmware
features to be enabled or disabled. The ID should be incremented with each revision of the PCB.

Front Panel UART Connection
A debug UART connection is provided out the front panel on RJ45 port 3.
Hot Plug
The PMC is hot-pluggable. It can be removed and inserted without causing interference to the behavior of the shelf or any incorrect alerts or
errors to be recorded. When inserted, the PMC will interface with the shelf and assume any defined functionality once synchronized with the
PSUs.
Sensor
The PMC has a temperature sensor connected to the SOM via ADC. This current value is available from Redfish.
Miscellaneous Peripherals
Item
I2C for Internal EEPROM
I2C for Shelf EEPROM
LAN Reset
The PMC provides a LAN reset option. This feature allows the user to reset the IP Address to default.
The LAN Reset can be triggered through an RS232 debug port command.
Description
The PMC supports one I2C bus connection to the PMC carrier FRU.
The PMC supports one I2C bus connection to the PSU shelf FRU. (Reserved)
