Automatic monitoring refers to the switch’s inbuilt sensors that automatically monitor operations. The majority of
automatic monitoring is provided by the CMM. If an error is detected (e.g., over-threshold temperature), the CMM
immediately sends a trap to the user. The trap is displayed on the console in the form of a text error message. (In the case
of an over-threshold temperature condition, the CMM displays an amber TEMP LED in addition to sending a trap.)

LEDs, which provide visual status information, are provided on the CMM, NI, and power supply front panels. LEDs are
used to indicate conditions, such as hardware and software status, temperature errors, link integrity, data flow, etc.

User-driven hardware monitoring refers to CLI commands that are entered by the user in order to access the current status
of hardware components. The user enters “show” commands that output information to the console.

Front Panel LEDs
All NIs provide a series of status LEDs located on the front panel. These LEDs offer basic status information for the
following functions:
following functions:
• NI hardware operation
• NI software status
• Port link and activity status

The power checking sequence is another inbuilt Availability feature. This feature helps regulate power in the switch
whenever the switch is booted or an NI module is installed in the chassis.
The sequence is a joint effort between the CMM, the NI modules, and the power supplies. During the boot sequence, the
primary CMM automatically compares the power consumption required by installed NIs with the power available from
the power supplies. If there is not adequate power to support all NIs, the CMM will power on only the supported number
of NIs, starting from the first NI slot position.
Important. During the power checking sequence, CMMs receive priority and are always powered on. NI modules
are then powered on sequentially by slot position. In other words, the NI in slot 1 is powered on, then slot 2, then
slot 3, etc.

When an NI module is installed in the chassis, only a small portion of the circuitry is initially powered up. The CMM
immediately reads the incoming module’s ID and determines how much power the module will require. If the number of
power supplies installed in the chassis can provide sufficient power, the CMM turns on the incoming module. If the
number of installed power supplies cannot provide sufficient power, the incoming NI will remain powered off.
