Using the shelf manager CLI
You can use the shelf manager command line interface (CLI) to communicate with the intelligent management
controllers of the chassis, with boards in the chassis, and with the shelf manager itself. The CLI is an IPMI-based set of
commands that can be accessed directly or through a higher-level management application or a script. Using the CLI,
you can access information about the current state of the chassis including current board population, current sensor
values, threshold settings, recent events, and overall chassis health.
To get started using the shelf manager CLI, see

Shelf Manager fan and power control
The FortiGate-5144C shelf managers monitor the internal temperature of the chassis and adjust the operating speed of
the cooling fans as required.
When the chassis is first powered on all cooling fans run at full speed. Once the shelf manager is up and running, the
shelf manager reduces cooling fan speeds to maintain an optimum temperature in the chassis. If shelf managers are
not installed or not operating correctly the FortiGate-5144C chassis cooling fans always operate at full speed.
Telco alarms
The Telco Alarm Interface is a standard DB-15 male Telco Form-c connector. The external dry relay Telco alarm
interface (48VDC) provides Telco form-c relay connections for minor, major and critical power faults. The cable required
to connect to the alarm interface is not supplied by Fortinet. To monitor alarms you should connect to the telco alarm
interface of the active shelf alarm panel, which by default is the one on the left.
The Telco alarm interface relay circuits are capable of carrying 60 VDC or 1 A with a max. rating of 30 VA. The shelf
alarm panel accepts timed pulse inputs for clearing minor and major alarm states. Reset is accomplished by asserting a
voltage differential from 3.3 V to 48 V for between 200 and 300 ms. The acceptance voltage range is from 0 to 48 VDC
continuous (handles up to 60 VDC at a 50% duty cycle). The current drawn by a reset input does not exceed 12 mA.
