FortiGate-7060E Management Modules

The FortiGate-7060E chassis includes two hot swappable management modules (shelf managers), located at the top of the chassis front panel. The management models operate in an active-passive redundant configuration. By default, when the system starts up the management module in slot MGT2 is active and the management module in slot MGT1 is passive. The active management module always has IPMB address 0x20 and the passive management module always has IPMB address 0x22.

The management modules are hot swappable. If you remove the passive management module, or if the passive management module fails, the chassis just keeps operating with the active management module. If you remove the active management module, or if the active management module fails, the passive management module becomes active. If you insert a new management module it quietly starts up and becomes passive. The active management module synchronizes the following data to the passive management module:

l Chassis state and chassis policy l 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. l The console connect feature status (enable or disable).

FortiGate-7060E management module front panel

The active management module 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 management module includes LED indicators that report on the status of many of the chassis components, including fans trays and power supplies. You can also use the management module console ports to connect to the management module CLI and to the CLI of the modules in chassis slots 1 to 6.

Management Module LEDs

The active management module 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 management module through the module’s IPMC.

Management modules are hot swappable. You can replace a management module by loosening its retention screws, then pulling it out of the chassis. When a management module is removed, the other management module continues providing management functions. If both management module are removed, chassis fans speed up to maximum speed.

When an FIM or FPM module detects the absence of a management module for more than 30 seconds, the module will go to Standalone Mode. In standalone mode the modules autonomously control their own power. When a management module becomes the active management module, it assumes control of chassis fans, and the FIM and FPM modules switch back to normal mode.

In normal mode, FIM and FPM module power on/off requires authorization from the active management module and the management module 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 management module SMC SDI. You can connect a serial cable to the active management module console ports to connect to the management module 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.

Management Module LEDs

The following table describes the management Module LED indicators:

FortiGate-7060E Management Module LEDs

LED                                   State		Description
Status	Off	The management module is powered off or not initialized.
	Solid Red	The management module is not operating normally either because it is starting up or because it has failed.
	Blinking Red	The active management module cannot communicate with the passive management module.
	Solid Green	The management module has started up and is operating normally.
	Blinking Green	The management module is passive.

Management Module LEDs

LED	State	Description
Alarm	Off	No alarms
	Red	One or more analog sensors in the chassis or on a module in the chassis (other than PSUs) have surpassed a critical or non-recoverable (NR) threshold causing an alarm. When a critical threshold has been reached, it means that a condition has been detected that has surpassed an operating tolerance. For example, a temperature has increased above the allowed operating temperature range.
	Amber	One or more analog sensors in the chassis or on a module in the chassis (excluding PSUs) has surpassed a major or critical (CR) threshold. Any sensor, including sensors on PSUs, has generated an alert. Sensor alert criteria is defined per sensor. For analog sensors, alerts usually mean passing an upper critical (UC) or lower critical (LC) threshold. For other sensors, an alert could mean a flag bit is indicating an anomaly.
Temp	Solid Green	All temperature sensors indicated acceptable operating temperatures.
	Blinking Green	At least one temperature sensor is detecting a high temperature outside of the normal operating range. In this case an upper non-critical (UNC) temperature. The management module increases fan speed to increase cooling and reduce the temperature.
	Blinking Red	At least one temperature sensor is detecting a temperature outside of the acceptable operating range. In this case an upper critical (UC) temperature. The management module increases fan speed to the maximum level. This also indicates possible problems with the cooling system and could mean that the ambient temperature is too high. Also causes a major or critical (CR) alarm.
	Solid Red	At least one temperature sensor is detecting a temperature outside of the allowed operating range. In this case an upper non-recoverable (UNR) temperature. The management module increases fan speed to the maximum level. The temperature is high enough to potentially cause physical damage. Also causes a critical or non-recoverable (NR) alarm.

Management Module LEDs

LED                                   State		Description
Power	Solid Green	Normal operation.
	Blinking Green	Chassis 12V disabled. This means that the administrator has entered commands into the management module CLI to power off the PSU main 12V outputs. All fans, FIM and FPM modules are completely powered off but the management module is still running.
	Red	Chassis 12V enabled but not OK. This means the management module has enabled the main 12V outputs for all chassis components, but the power OK (PWOK) signal of at least one PSU has not been sent. When a PSU is powering up, it would be normal for this LED to be red for a second (before PSU outputs are stabilized), but if LED remains red, it indicates a problem (such as a failed PSU). Management module or FIM or FPM module voltage sensors would most likely also trigger alarms if this happens since the PSUs may not be delivering enough power.
FAN (LEDs for each of three fan trays) PSU (LEDs for each of four PSUs)	Off	Fan tachometer sensors disabled. This could happen if the administrator disabled them from the management module CLI.
	Green	The fan tray is operating normally.
	Blinking Red	The fan tray is not working. Chassis cooling may be sufficient but redundancy is lost and the fan tray that is not working should be replaced.
	Red	A fan tachometer sensor in this fan tray has registered an alert because a critical or non-recoverable (NR) threshold has been crossed.
	Off	The PSU is not installed in the chassis.
	Green	The PSU is present and operating normally.
	Blinking Red	The PSU module is installed but no power is being delivered (not plugged in).
	Red	The PSU’s sensors have detected an alert condition. The PSU’s analog sensors crossed critical or non-recoverable (NR) thresholds, or the PSU Status Failure bit has been set.

About management module alarm levels

LED	State	Description
Console 1 and 2	Off	This console port is not connected or is connected to the management module SMM CLI.
	Green	This console port is connected to this module host console in this chassis slot.
	Amber	This console port is connected to this module’s SMC console.

About management module alarm levels

Minor, major and critical alarms are defined based on both IPMI, ATCA, and Telco standards for naming alarms.

• A minor alarm (also called an IPMI non-critical (NC) alarm) indicates that a temperature or a power level was detected by a sensor that is outside of the normal operating range but is not considered a problem. In the case of a minor temperature alarm the system could respond by increasing fan speed. A non-critical threshold can be an upper non-critical (UNC) threshold (for example, a high temperature or a high power level ) or a lower non-critical (UNC) threshold (for example, a low power level). l A major alarm (also called an IPMI critical or critical recoverable (CR) alarm) indicates a temperature or power level was detected by a sensor that is far enough outside of the normal operating range to require attention from the operator. It could also mean that the system itself cannot correct the alarm. For example, the cooling system cannot provide enough cooling to reduce the temperature. It could also mean that conditions are close to being outside of the allowed operating range. For example, the temperature is close to exceeding the allowed operating temperature. A critical threshold can also be an upper critical (UC) threshold (for example, a high temperature or a high power level ) or a lower critical (LC) threshold (for example, a low power level).
• A critical alarm (also called an IPMI non-recoverable (NR) alarm) indicates a temperature or power level was detected by a sensor that is outside of the allowed operating range and could potentially cause physical damage.

You can use the management module CLI to get details about alarm sensors, thresholds, and the events that trigger alarms.

Using the console ports

The active management module includes two console ports named Console 1 and Console 2 that can be used to connect to any serial console in the chassis. This includes the management module CLI, the FortiOS CLIs (also called host CLIs) of the FIM and FPM modules in chassis slots 1 to 6 and all of the SMC SDI consoles in the chassis.

Each module, including the management modules, includes an SMC SDI console. These consoles are used for low level programming of the module using an IPMI tool and are disabled by default. You can enable serial access to individual module SMC SDI consoles from the management module SMC SDI CLI using the command serial set sdi enable <slot>. During normal operation you may want to access the management module SMC SDI CLI, you shouldn’t normally require access to individual module SMC SDI consoles.

Connecting to the FortiOS CLI of the FIM module in slot 1

By default when the chassis first starts up Console 1 is connected to the FortiOS CLI of the FIM module in slot 1 and Console 2 is disconnected.

The default settings for connecting to each console port are: Baud Rate (bps) 9600, Data bits 8, Parity None, Stop bits 1, and Flow Control None.

The FIM and FPM modules use the standard FortiOS CLI. The SMC SDI CLIs are described in this chapter. You can use the console connection change buttons to select the CLI that each console port is connected to.

• Press the button to cycle through the FIM and FPM module FortiOS CLIs and disconnect this console.
• Press and hold the button to connect to the management module SMC SDI CLI. You can also cycle through each module’s SMC SDI CLI if they are enabled.

The console’s LEDs indicate what it is connected to. If no LED is lit the console is either connected to the management module SMC SDI console or disconnected. Both console ports cannot be connected to the same CLI at the same time. If a console button press would cause a conflict that module is skipped. If one of the console ports is disconnected then the other console port can connect to any CLI.

If you connect a PC to one of the management module console ports with a serial cable and open a terminal session you begin by pressing Ctrl-T to enable console switching mode, then you can do the following:

• Press Ctrl-T to cycle through the FIM and FPM module FortiOS CLIs (the new destination is displayed in the terminal window). If you press Ctrl-T after connecting to the FPM module in slot 6 the console is disconnected. Press Ctrl-T again to start over again at slot 1.
• Press Ctrl-R to connect to the management module SMC SDI CLI. You can also cycle through each module’s SMC SDI CLI if they are enabled (the new destination is displayed in the terminal window). After cycling through all of the enabled SMC SDI CLIs the next press of Ctrl-R disconnects the console port.

Once the console port is connected to the CLI that you want to use, press Ctrl-G to enable the CLI. When your session is complete you can press Ctrl-G to disable the CLI.

7. When your session is complete, enter the exit command to log out.
8. Optionally press Ctrl-G to disable the CLI.

Changing the management module admin account password

Use the following procedure to change the management module admin account password.

1. Enter the following command to show all users and their user IDs. user list

The output should show that the admin user has a user ID of 2.

2. Use the command user set password <user-id> [<password>] to add a password for the admin account. For example:

user set password 2 <password>

3. Enter and confirm a new password for the admin

The password should be between 5 and 20 characters long and should include a combination of upper and lower case letters and numbers.

You can change the admin account password at any time.

Connecting to the management module using an IPMI tool

Connecting to the management module using an IPMI tool

You can install a remote IPMI tool on a management computer and then use this IPMI tool to start an IPMI session with the management module. You can use one of the console ports or the MGMT port to connect with the IPMI tool.

The IPMI commands are the same as the CLI commands described in this chapter but they have to be prefixed as shown in the following example that changes the MGMT interface IP address to 172.20.120.30 over a serial connection:

sudo ipmitool -I serial-terminal -D /dev/ttyS1:9600 -U <username> -P <password> lan set 4 ipaddr 172.20.120.30

Here is the same command over an Ethernet connection:

sudo ipmitool -I lanplus -H 10.160.19.30 -k gkey -U <username> -P <password> lan set 4 ipaddr 172.20.120.30

Use the following IPMI commands to change the management module password:

First from a console port connection:

sudo ipmitool -I serial-terminal -D /dev/ttyS1:9600 -U <username> -P <password> user set password 2 <password> And from an Ethernet connection:

sudo ipmitool -I lanplus -H 10.160.19.30 -k gkey -U <username> -P <password> user set password 2 <password>

To perform an operation on a module according to its chassis slot include the -t <slot> parameter in the IPMI command. For example, to list the sensors on the FIM module in chassis slot 2 (0x82), use the following IPMI command:

sudo ipmitool -I lanplus -H 10.160.19.30 -k gkey -U <username> -P <password0> -t 0x82 sensor
