FortiGate-7121F System Management Module

The FortiGate-7121F chassis includes two System Management Modules (SMMs) or shelf managers, located at the top of the chassis front panel. The SMMs are factory installed and configured and are not field replaceable.

The SMMs operate in an active-passive redundant configuration. By default, when the system starts up the SMM in slot M2 is active and the SMM in slot M1 is passive. The active SMM always has IPMB address 0x20 and the passive SMM always has IPMB address 0x22. Active and passive refers to the SMM that is controlling the chassis. The MGMT interfaces and console ports on both SMMs are always available if the SMM is operating.

If the passive SMM fails, the chassis just keeps operating with the active SMM. If the active SMM fails, the passive SMM becomes active.

The active SMM synchronizes the following data to the passive SMM:

  • Chassis state and chassis policy
  • LAN parameters for each LAN channel, including, the IP address, gateway IP address, channel enable status, local interface/non-local interface setting, and the session support flag.

The active SMM communicates with module SMCs in the chassis, each of which is responsible for local management of one or more Field Replaceable Units (FRUs), including FIM and FPM modules, fan trays, and power supplies. Management communication within a chassis occurs over the Intelligent Platform Management Bus (IPMB).

The active SMM includes LED indicators that report on the status of many of the chassis components, including fan trays and power supplies. You can also use the SMM console ports to connect to the SMM CLI and to the CLI of the modules in chassis slots 1 to 12.

The active SMM controls chassis power allocation, monitors chassis operating parameters, monitors and controls chassis cooling, and generates alarms if the chassis encounters problems. All FIM and FPM modules installed in the chassis communicate with the active SMM through the module's IPMB. FIM and FPM module power on/off requires authorization from the active SMM and the active SMM controls the power supplied by the chassis power systems to the modules.

Each module in the chassis includes its own module Shelf Manager Controller (SMC) Serial Debug Interface (SDI) or SMC SDI console that communicates with the SMM SMC SDI. You can connect a serial cable to the active SMM console ports to connect to the SMM SMC SDI and to connect to each module's SMC SDI console. You can also interact with the SMC SDI consoles using an Intelligent Platform Management Interface (IPMI) tool.
