devices are typically called FRUs. The term FRU generally refers to any removable or field replaceable component,
but in a more technical view can be any unique device in the system even if it is not removable, such as a
backplane.

FortiGate-5001A in ATCA slot 1 = (IPMC 82) FRU 0
l
Shelf Manager in SM slot 1 = (IPMC 10) FRU 0
l
Shelf Manager in SM slot 2 = (IPMC 12) FRU 0
All the other FRU devices that make up a chassis are referenced through the logical IPMC address 20.
Fan Tray 1 = (IPMC 20) FRU 3
Fan Tray 2 = (IPMC 20) FRU 4
PEM1 (A1) = (IPMC 20) FRU 7
See
IPMB addresses, logical and physical slot numbers, and FRU ids on page 39
for a complete list.
The sensors on the various FRUs report back to their respective IPMC. Sensors connected to chassis FRU devices like
the fan trays or power entry modules can report back their sensor readings through either IPMC 10h/12h or through the
Logical 20h address, but not both. Sensors on ATCA boards always report back through their respective blade IPMC
address.

You can check the IPMB bus state (if the bus it in failure, nothing works). A backup bus exists so there are 2 IPMB buses
handled by the active shelf manager (and not one bus per shelf manager). Use the following command to check the
IPMB bus state:
# clia getipmbstate 10
Pigeon Point Shelf Manager Command Line Interpreter
10: Link: 0, LUN: 0, Sensor # 1 ("IPMB LINK")
Bus Status: 0x8 (IPMB-A Enabled, IPMB-B Enabled)
IPMB A State: 0x08 (LocalControl, No failure)
IPMB B State: 0x08 (LocalControl, No failure)
Alarm LEDs
Alarms are also reported by LEDs on the chassis shelf alarm panel or shelf manager. FRUs such as fan trays and PEMs
also have alarm LEDs. So for example, if a FAN goes into an alarm state, the alarm LED located on the FAN turns to
RED.
Reading the SEL
Every time an event occurs in a chassis, the respective IPMC controller sends notification to the shelf manager that the
event has happened and an entry is added to the SEL. The log entry that is created depends on the sensor that
triggered the event and the type of data that the sensor reads.
