The tables in this section provide additional information
to help you resolve events 0x00020000 - 0x00020036. For each chassis
type, these tables lists the I2C buses and the device or devices on
that bus.
Redundant I2C buses are used to communicate between the
management module and the media tray, blowers, power modules, and
I/O switch modules. When the management module cannot communicate
with a device, it generates an event in the event log that provides
the device number on the bus.
Each BladeCenter chassis has
a different number of I2C devices; therefore, the meaning of the event
is specific to a chassis type. In some cases, there is a specific
device on the bus. For example, bus 10 on a BladeCenter
H chassis is I/O Module 1. In other cases, a group of devices are
on a bus. For example, multiple I/O modules are on bus 5 on a BladeCenter
E chassis.
Note: It takes from two to five minutes for the I2C bus
to reset itself and clear any faults. Keep this time frame in mind
when resetting or adding devices for the I2C bus.
