Znyx Networks bh5700 manual Event Generator, Field Replaceable Unit Inventory Device

Event Generator

The PMC’s event generator is disabled until it receives a SetEventReceiver command from BMC for Event Receiver’s slave address and LUN. If the event generator is enabled, PMC reports significant events to the BMC asynchronously.

The standard IPMI platform event message format is used.

IPMB Event message format

Structure of event messages sent to the BMC by PM device (PMC) is shown below.

IPMB Event Message Format

Byte	Data Field	Byte Description
1	EvMRev	<event_msg_rev>
2	Sensor Type	<sensor_type>
3	Sensor #	<sensor_number>
4	Event Dir Type	<direction, type> bit: 7
4	Event Type	<type> bits: 0-6
5	Event Data 1	<arg1>
6	Event Data 2	<arg2>
7	Event Data 3	<arg3>

IPMI Event Message Definitions

The following tables describe the IPMI event messages to be generated by the PMC. The basic requirement is that when a monitored sensor changes state, an event must be generated and sent to BMC.

Field Replaceable Unit Inventory Device

A Field Replaceable Unit Inventory Device (FRU ID) file is generated for the Ethernet Switch Blade in binary format. At manufacturing, the file is loaded at the same time as the boot and runtime files to a specified space, which is reserved in the spare SEEPROM on I2C bus number 1 at device address 0xA2. The FRU information is product specific and, in addition, may be customer specific. At boot time, the IPMI firmware will read the product serial number from the board’s VPD file to FRU’s product Information Area.
