1.1 Terminology and Acronym Definitions
The following table provides descriptions for terms and acronyms used in this guide. The de-
scriptions are derived primarily from the IPMI specifications.
Table 1: Terminology and Acronym Definitions
TERM or ACRONYM DESCRIPTION
Carrier Manager A logical function that manages and controls the AdvancedMC Modules, OEM
Modules, PMs, and CUs in a MicroTCA Carrier through a set of signals controlled by
the PMs together with the IPMB links
Cooling Unit (CU) A subassembly including fans or blowers to move air to cool a MicroTCA Shelf and
related support electronics
Electronic Keying or
E-Keying Abbreviation for Electronic Keying. Electronic Keying defines the process in which a
MicroTCA Shelf determines if the Control and Fabric interfaces on a Module are
compatible with the MicroTCA Shelf interconnects and the other Modules they reach.
EMMC Enhanced Module Management Controller, used on Cooling Units, Power Module,
and OEM Modules. See Module Management Controller (MMC).
Fabric Interface The set of MCH Fabric Channel interfaces that provides up to seven Fabric Channels
to the AdvancedMCs
Fabric, Fabric Channel The connection where the MCH is the endpoint of a Slot-to-Slot connection of one-to
-four ports on an AdvancedMC
FRU Field Replaceable Unit, any entity that can be replaced by a user in the field
FRU Device ID A value that uniquely identifies a FRU relative to an IPM Controller. In MicroTCA the
most frequent use of FRU Device ID is to uniquely identify a FRU within a MicroTCA
Carrier relative to the Carrier Manager.
FRU Information Data that describes a FRU with an emphasis on data that characterizes the FRU.
Format for this data is described in IPMI Platform Management FRU Information
Storage Definition and extended herein.
Handle An item or part used to insert or extract Modules in and out of Slots
Hot Swap To remove a component (e.g., an AdvancedMC Module) from a system (e.g., an
MicroTCA Shelf) and plug in a new one while the power is still on and the system is
still operating
Hot Swap Switch A switch that is integrated with the Module Latch Mechanism so that its state reflects
the state of the Latch. The Hot Swap Switch is disconnected when the Module Handle
is fully inserted.
I2C Inter-integrated Circuit bus, a multi-master, two-wire serial bus used as the basis for
IPMBs
