Displaying Temperatures for Modules

Each supervisior, I/O, and fabric module has temperature sensors with two thresholds:

  • Minor temperature threshold—When a minor threshold is exceeded, a minor alarm occurs and the following actions occur for all four sensors:
    • Displays system messages
    • Sends Call Home alerts (if configured)
    • Sends SNMP notifications (if configured)
  • Major temperature threshold—When a major threshold is exceeded, a major alarm occurs and the following actions occur:
    • For sensors 1, 3, and 4 (outlet and onboard sensors), the following actions occur:
      • Displays system messages.
      • Sends Call Home alerts (if configured).
      • Sends SNMP notifications (if configured).
    • For sensor 2 (intake sensor), the following actions occur:
      • If the threshold is exceeded in a switching module, only that module is shut down.
      • If the threshold is exceeded in an active supervisor module with HA-standby or standby present, only that supervisor module is shut down and the standby supervisor module takes over.
      • If you do not have a standby supervisor module in your switch, you have up to 2 minutes to decrease the temperature. During this interval, the software monitors the temperature every 5 seconds and continuously sends system messages as configured.

        Tip


        We recommend that you install dual supervisor modules. If you are using a switch without dual supervisor modules, we recommend that you immediately replace the fan module if just one fan is not working.



Note


A threshold value of -127 indicates that no thresholds are configured or applicable.


You can display temperature readings for module temperature sensors by using the show environment temperature command.

Enter the show environment temperature command.

Example:
switch# show environment temperature

Connecting to a Module

At any time, you can connect to any module by using the attach module command. Once you are at the module prompt, you can obtain further details about the module by using module-specific commands in EXEC mode.

You can also use the attach module command to display the standby supervisor module information, although you cannot configure the standby supervisor module using this command.


    Step 1   Enter the attach module slot_number command.

    Example:
    switch# attach module 4
    switch(standby)#

    Provides direct access to the specified module (in this example, the standby supervisor module is in slot 6).

    Step 2   dir bootflash


    Example:
    switch(standby)# dir bootflash
    Example:
    switch# dir bootflash:
       80667580     Feb 21 22:04:59 2008  is855.S7
       22168064     Feb 21 22:04:19 2008  ks855.S7
          16384     Jan 03 19:56:00 2005  lost+found/
    Usage for bootflash://sup-local
      234045440 bytes used
     1684602880 bytes free
     1918648320 bytes total
    switch# 
    
    

    Provides the available space information for the standby supervisor module.

    Note   

    To exit the module-specific prompt, use the exit command.

    Tip   

    If you are not accessing the switch from a console terminal, this step is the only way to access the standby supervisor module.


    Saving the Module Configuration

    To save the new configuration to nonvolatile storage, use the copy running-config startup-config command from EXEC mode. Once you enter this command, the running and the startup copies of the configuration are identical.

    The following table lists various scenarios when module configurations are preserved or lost.

    Scenario

    Consequence

    A particular switching module is removed and you used the copy running-config startup-config command again.

    The configured module information is lost.

    A particular switching module is removed and the same switching module is replaced before you enter the copy running-config startup-config command again.

    The configured module information is preserved.

    A particular switching module is removed and replaced with the same type switching module, and you entered the reload module slot_number command.

    The configured module information is preserved.

    A particular switching module is reloaded when you enter the reload module slot_number command.

    The configured module information is preserved.

    Displaying Power Usage Information

    To display the power usage information for the entire switch, use the show environment power command. This command shows the power usage for many of the modules installed in the switch. For the older modules that do not have the capability to output this information, the output is shown as N/A.


    Note


    Power usage is reserved for both supervisor modules regardless of whether one or both supervisor modules are present.


    Enter the show environment power command.

    Power Cycling a Module

    You can reset a module by using the reload module command and specifying the module by its slot number in the chassis.


    Caution


    Reloading a module disrupts traffic through the module.



      Step 1   Enter the configure terminal command to enter the configuration terminal mode.

      Example:
      switch# configure terminal
      switch(config)#
      Step 2   Specify the slot number for the module that you are resetting by entering the reload module slot_numbercommand.

      Example:
      switch(config)# reload module 2

      Rebooting the Switch

      To reboot or reload the switch, use the reload command without any options. When you use this command, you reboot the switch.


      Note


      If you need to use the reload command, be sure to save the running configuration by using the copy running-config startup-config command beforehand.



        Step 1   Start the configuration mode by entering the configure terminal command.

        Example:
        switch# configure terminal
        switch(config)#
        Step 2   Save the running configuration by entering the copy running-config startup-config command.

        Example:
        switch(config)# copy running-config startup-config
        Step 3   Reload the switch by entering the reload command.

        Example:
        switch(config)# reload

        Overview of Supervisor Modules

        The switch has one or two supervisor modules of the following types:

        • Supervisor 2 Enhanced (N77-SUP2E)

        When a switch has two supervisors, one supervisor is automatically active while the other is in standby mode. If the active supervisor goes down or is disconnected for replacement, the standby supervisor automatically becomes active. If you need to replace one of two installed supervisor modules with another module, you can do this without interrupting operations—the supervisor that you are not replacing becomes the active supervisor and retains the kickstart configuration while you replace the other supervisor. If the switch has just one supervisor, you can install the new supervisor in the open supervisor slot during operations and make that supervisor active after the installation.

        Supervisor modules are automatically powered up and started with the switch.

        To understand the terms used for the supervisors, see the following table.

        Module Terms

        Usage

        Description

        module-5 and module-6

        Fixed

        • Module-5 refers to the supervisor module in chassis slot 5.
        • Module-6 refers to the supervisor module in chassis slot 6.

        sup-1 and sup-2

        Fixed

        • sup-1 refers to the supervisor module in slot 5.
        • sup-2 refers to the supervisor module in slot 6.

        sup-active and sup-standby

        Relative

        • sup-active refers to the active supervisor module—relative to the slot that contains the active supervisor module.
        • sup-standby refers to the standby supervisor module—relative to the slot that contains the standby supervisor module.

        sup-local and sup-remote

        Relative

        If you are logged into the active supervisor, the following applies:

        • sup-local refers to the active supervisor module.
        • sup-remote refers to the standby supervisor module.

        If you are logged into the standby supervisor, the following applies:

        • sup-local refers to the standby supervisor module (the one that you are logged into).
        • There is no sup-remote available from the standby supervisor module (you cannot access a file system on the active supervisor).

        Shutting Down a Supervisor Module

        To shut down a supervisor module, use the out-of-service module command to specify the chassis slot with that module.


          Step 1   Start the configuration mode by entering the configure terminal command.

          Example:
          switch# configure terminal
          switch(config)#
          Step 2   Take the supervisor module out of service by entering the out-of-service module slot_number command.

          Example:
          switch(config)# out-of-service module 5
          switch(config)#
          

          Overview of I/O Module Support

          Accessing an I/O Module through a Console

          You can troubleshoot bootup problems for an I/O module by accessing the module through its console port. This action establishes a console mode that you must exit in order to use other Cisco NX-OS commands.

          To attach to the console port for an I/O module, use the attach console module command to specify the module you need to work with. Specify a slot from 1 to 4 or from 7 to 10.


          Note


          To exit the console mode, enter the ~, command.


          Attach to the console port for the I/O module by entering the attach console module slot_number command.

          Example:
          switch# attach console module 3
          connected
          Escape character is `~,' (tilde comma]

          Displaying Information for the Installed Modules

          You can display information about the modules installed in the switch chassis by using the show module command. This information includes module type, bootup status, MAC addresses, serial numbers, software versions, and hardware versions. You can use this command in the following ways to display information about all of the installed module or specific modules:

          • For information on all modules, use the show module command.
          • For information on a specific supervisor or I/O module, use the show module slot_number command to specify a slot number.
          • For information on a specific fabric module, use the show module xbar slot_number command to specify a slot number.

          For a description of the module status indicated by one of the above show module commands, see the following table.

          I/O Module State Description

          Purging the Module Configuration

          You can clear the running configuration for an I/O slot that is not functioning by using the purge module command in EXEC mode.


          Note


          This command does not work on supervisor slots nor on any I/O slot that currently has a powered-up module.


          Before You Begin

          Verify that either the I/O slot is empty or the I/O module installed in the slot is powered down.

          Clear the running configuration by using the purge module slot_number runnning-config command.

          Example:switch# purge module 4 running-config

          For example, suppose you create an IP storage configuration with a 48-port 10/100/1000 Ethernet I/O module in slot 3 of Switch A. This module uses an IP address. You decide to remove this I/O module and move it to Switch B, and you no longer need the IP address. If you try to configure this unused IP address, you will receive an error message that prevents you from proceeding with the configuration. In this case, you need to enter the purge module 3 running-config command to clear the old configuration in Switch A before using the IP address.

          Shut Down or Power Up an I/O Module

          You can shutdown or power up an I/O module by using the poweroff module or no poweroff module command to specify the module by its slot number in the chassis.


            Step 1   Start the configuration mode by entering the configure terminal command.

            Example:
            switch# configure terminal
            switch(config)#
            Step 2   Shutdown the module by entering the [no] shutdown module slot_number command.

            Example:
            switch(config)# poweroff module 2
            switch(config)#
            


            Example:
            switch(config)# no poweroff module 2
            switch(config)#
            

            Overview of Fabric Module Support

            This switch supports the following fabric modules:

            • Fabric 2 (N77-C7710-FAB-2)

            Change the Amount of Power Reserved for Fabric Modules

            By default, each switch reserves enough power for the maximum quantity of fabric modules that can be installed in its chassis. If you have installed fewer than the maximum number of fabric modules and need to free up unused reserve power for I/O modules, you can power down the unused slots and specify a smaller maximum number of modules.

            To specify a different maximum number of fabric modules for your system, use the hardware fabrics max number command. To verify the status of the installed fabric modules, use the show module xbar command. To verify the amount of reserved power, use the show environment power command.

            Before You Begin
            • Make sure that the fabric modules that you are using are installed in slots 1 through x where x is the new maximum number of fabric modules. You do not have to fill all of the fabric slots, but the fabric modules that you install must be in slots 1 through x. For example, if you specify 4 as the new maximum number of fabric modules, you must make sure that the fabric modules that you are using are in slots 1 through 4. Also, make sure that any empty fabric module slots have blank filler plates installed in them.
            • Make sure that each of the installed fabric modules is powered up by using the no poweroff xbar slot_number command (see Shutting Down or Powering Up a Fabric Module).
            • Power down the unused slots by using the poweroff xbar slot_number command (see Shutting Down or Powering Up a Fabric Module).

              Step 1   Start the configuration mode by entering the configure terminal command.

              Example:
              switch# configure terminal
              switch(config)#
              Step 2   Power off specific a specific fabric module by using the hardware fabrics max quantity command. Use a digit between 1 and 6, inclusive.

              Example:
              switch(config)#  hardware fabrics max 4
              switch(config)#

              Shutting Down or Powering Up a Fabric Module

              To shut down a fabric module, use either the out-of-service xbar command or the poweroff xbar command. If you use the poweroff xbar command, the slot remains in that state until you use the no poweroff command. If you use the out-of-service xbar command, the out-of-service state remains in effect until you do something like remove the module and replace it with another module.


              Note


              If you are going to limit the maximum number of fabric modules, make sure that powered-on fabric modules are in the first n fabric module slots, where n is the new maximum number of fabric modules. For example, if you are limiting the maximum number of fabric modules to 4, you must make sure that the four powered-on fabric modules are in fabric slots 1 through 4.

              If you are powering up more fabric modules than allowed by the current maximum number of fabric modules, then make sure that the fabric modules that you are powering up are installed in the first n fabric slots (slots 1 through n), power-on those modules with the no poweroff xbar command, and change the maximum number of fabric modules to n (see Change the Amount of Power Reserved for Fabric Modules).



                Step 1   Start the configuration mode by entering the configure terminal command.

                Example:
                switch# configure terminal
                switch(config)#
                Step 2   Shut down or power up the specified fabric module by entering the [no] shutdown xbar slot_number command.

                Example:
                switch(config)# poweroff xbar 1
                switch(config)#
                


                Example:
                switch(config)# no poweroff xbar 1
                switch(config)#
                

                Power Modes Overview

                You can configure one of the following power modes to either use the combined power provided by the installed power supply units (no power redundancy) or to provide power redundancy when there is a power loss:

                Combined mode

                This mode allocates the combined power of all power supplies to active power for switch operations. This mode does not allocate reserve power for power redundancy in case of power outages or power supply failures.

                Power-supply ( n+1) redundancy mode

                This mode allocates one power supply as a reserve power supply in case an available power supply fails. The remaining power supplies are allocated for available power. The reserve power supply must be at least as powerful as each power supply used for the available power.

                For example, if a switch requires 5.2 kW of available power and the switch has three power supplies that each output 3-kW, then two of the power supplies provide 6.0 kW of available power and one power supply provides 3.0 kW of reserve power in case another power supply fails.

                Input-source (grid) redundancy mode

                This mode allocates half of the power to available power and the other half to reserve power. You must use a different power source for the active and reserve power sources so that if the power source used for active power fails, the other power source used for the reserve power can provide power for the switch.

                For example, if the switch requires 5.2 kW of power, the switch has four power supplies that each output 3 kW, and there are two 220-V power grids, then you use grid A to power two 3-kW power supplies that provide the available power to power the switch and you use grid B to power the other two 3-kW power supplies that provide the reserve power in case grid A fails.

                Full redundancy mode

                This mode provides both power-supply (n+1) and input-source (grid) redundancies. As happens with the input-source redundancy mode, this mode allocates half of the power supplies to provide available power and the other half of the power supplies to provide the reserve power. One of the reserve power supplies can alternatively be used to provide power if a power supply supplying the available power fails.

                Guidelines for Configuring Power Redundancy Modes

                The amounts of available and reserve power depend on the power redundancy mode that you specify and the number of power supplies installed in the switch. For each redundancy mode, consider the following:

                Combined mode

                The available power equals the combined output of all installed power supplies. There is no reserve power. You activate this mode by using the power redundancy-mode combined command.

                For example, if the power requirement for a switch is 5.2 kW and the switch has one 3-kW power supply with 220 V input and 3.0-kW output, consider the following power planning scenarios:

                • Scenario 1—no added power supplies If you do not add a power supply unit, the available power (3.0 kW) is insufficient for the switch power requirement of 5.2 kW, so the switch powers the supervisor modules, fabric modules, and fan trays, before powering as many I/O modules as the remaining available power can support (one or more I/O modules will not be powered).
                • Scenario 2—install an extra 3-kW power supply If you install an additional 3-kW power supply unit that can output 3.0 kW, the available power becomes 6.0 kW. The increased amount of available power exceeds the switch power requirement of 5.2 kW, so all of the modules and fan trays in the switch can power up.

                The following table shows the results for each scenario.

                Scenario Power Requirement Power Supply 1 Output Power Supply 2 Output Available Power Reserve Power Result

                1

                5.2 kW

                3.0 kW

                3.0 kW

                Available power is less than the power requirement for the switch, so you cannot power the entire switch (some of the I/O modules will not be able to power up).

                2

                5.2 kW

                3.0 kW

                3.0 kW

                6.0 kW

                Available power exceeds the power requirement for the switch, so the entire switch can power up.

                Power supply ( n+1) redundancy mode

                The power supply that outputs the most power provides the reserve power so that it can take over for any other power supply that fails, and all of the other installed power supplies provide the available power. You activate this power mode by using the power redundancy-mode ps-redundant command.

                For example, if the power requirement for a switch is 5.2 kW and the switch has two 3.0 kW power supplies outputting 3.0 kW each (220-V input from the grid), consider the following power planning scenarios:

                • Scenario 1—no added power supplies One 3-kW power supply, which outputs just 3.0 kW for 110-V of input power, provides the reserve power and the other 3-kW power supply, also outputting 3.0 kW, provides the available power. The available power (3.0 kW) does not meet the switch requirements of 5.2 kW, so the switch powers up except for some of its I/O modules.
                • Scenario 2—adding one 3-kW power supply One 3-kW power supply, which outputs 1.45 kW, provides the reserve power and the other two 3-kW power supplies, also outputting 3.0 kW each, provide a sufficient amount of power (6.0 kW) to meet the switch requirements (5.2 kW), so the entire switch powers up.

                The following table shows the results for each scenario.

                Scenario Power Requirement Output (kW) for Power Supplies Available Power Reserve Power Result

                3.0 kW

                3.0 kW

                3.0 kW

                Available power is less than the power requirement for the switch, so you cannot power the entire switch (one or two of the I/O modules will not be able to power up).

                2

                5.2 kW

                3.0 kW

                3.0 kW

                3.0 kW

                6.0 kW

                3.0 kW

                Available power exceeds the power requirement for the switch, so the entire switch can power up.

                Input-source (grid) redundancy mode

                Half of the 3-kW power supplies are connected to one power source (grid) and the other half are connected to another power source. The available power is provided by one power source and the reserve power is provided by the other power source. If the power source providing the available power fails, the switch uses the reserve power source to provide its required power. You activate this power mode by using the power redundancy-mode insrc_redundant command.

                For example, if the power requirement for a switch is 5.2 kW, the switch uses two 220-V power sources, and the switch has two 3-kW power supplies (each outputting 3.0 kW when using 220-V power sources), consider the following power planning scenarios:

                • Scenario 1—no added power supplies The available power is 3.0 kW (output from one 3-kW power supply) and the reserve power is 3.0 kW (output from the other power supply). The available power (3.0 kW) does not meet the switch requirements (5.2 kW), so most of the modules will power up but some of the I/O modules will not be able to power up.
                • Scenario 2—adding two 3-kW power supplies The available power is 2.9 kW (output from two 3-kW power supplies on grid A) and the reserve power is 2.9 kW (output from the other two power supplies on grid B). The available power (2.9 kW) exceeds the power requirement of the switch (2.8 kW), so the entire switch can power up.

                The following table shows the results for each scenario.

                Scenario Power Requirement Output for Power Supplies Available Power Reserve Power Result
                1 2 3 4

                3.0 kW

                3.0 kW

                3.0 kW

                Available power (3.0 kW) is less than the power requirement for the switch (5.2 kW), so most of the switch can power up but one or more I/O modules cannot power up.

                2

                5.2 kW

                3.0 kW

                3.0 kW

                3.0 kW

                6.0 kW

                6.0 kW

                Available power (6.0 kW) exceeds the power requirement for the switch (5.2 kW), so the entire switch can power up.

                Full redundancy mode

                Full redundancy provides both power-supply redundancy and input-source redundancy. For power-supply redundancy, the power supply with the most output provides reserve power and the other power supplies provide the available power. For input-source redundancy, the available power is provided by one power source and the reserve power is provided by another power source, with half of the 3-kW power supplies are powered by one source and the other half are powered by the other source. You activate this power mode by using the power redundancy-mode redundant command.

                For example, if the power requirement for a switch is 2.8 kW, the switch uses two 110-V power sources, and the switch has two 3-kW power supplies (each outputting 1.45 kW for 110-V power sources), consider the following power planning scenarios:

                • Scenario 1—no added power supplies The available power is 1.45 kW (output from one 3-kW power supply using a 110-V power source) and the reserve power is 1.45 kW (output from the other power supply). The available power does not meet the switch requirements of 2.8 kW, so most of the modules will power up but one or more I/O modules will not be able to power up.
                • Scenario 2—adding two 3-kW power supplies The available power is 2.9 kW (output from two 3-kW power supplies using a 110-V power source) and the reserve power is 2.9 kW (output from the other two power supplies). The available power (2.9 kW) exceeds the power requirement of the switch (2.8 kW), so the entire switch can power up.

                The following table shows the results for each scenario.

                Scenario Power Rqmnt Output for Power Supplies Input Source Redundancy Power Source Redundancy Result

                4.35 kW

                1.45 kW

                Available power for both redundancies exceeds the switch requirements, so the entire switch can power up.

                Configuring the Power Mode

                You can configure the power supply mode by using the power redundancy-mode command.


                Note


                To display the current power supply configuration, use the show environment power command.



                  Step 1   Start the configuration mode by entering the configure terminal command.

                  Example:
                  switch# configure terminal
                  switch(config)#
                  Step 2   Specify one of the following power modes by entering the power redundancy-mode mode command:
                  • For combined mode, include the combined keyword.
                  • For power supply redundancy mode, include the ps-redundant keyword.
                  • For input source redundancy mode, include the insrc_redundant keyword.
                  • For full redundancy mode, include the redundant keyword.


                  Example:
                  switch(config)# power redundancy-mode redundant
                  switch(config)#

                  Maximum Power Available for 3-kW AC Power Supplies

                  The maximum power available for operations depends on the input power from your power source, the number and output capabilities of your power supplies, and the power redundancy mode that you use. The following table lists the amount of power available for 3-kW power supplies depending on power inputs, numbers of power supplies, and the mode used.

                  Overview of Fan Trays

                  Fan trays provide airflow through the switch for cooling. Each fan tray contains multiple fans to provide redundancy. The switch can continue functioning in the following situations:

                  • One or more fans fail within a fan tray—Even with multiple fan failures, the switch can continue functioning. When a fan fails within a tray, the functioning fans in the module increase their speed to compensate for the failed fans.
                  • The fan tray is removed for replacement—The fan tray is designed to be removed and replaced while the switch is operating without presenting an electrical hazard or damage to the switch. The switch can operate for three minutes without the fan tray that you are replacing, but if the switch air-inlet temperature is less than 86° Fahrenheit (30° C), you have up to 72 hours to replace the fan tray. Because temperatures can change over time, we recommend that you replace the fan tray within three minutes.
                  • If you remove more than one fan tray at a time, the switch can operate up to three minutes before shutting down. To prevent a shutdown, remove only one fan tray at a time.

                  Note


                  When a fan fails or when you remove a fan tray, the remaining operating fans speed up to compensate for the loss of fans. This can increase the noise made by the fan trays until you replace the missing fan tray or replace the defective fan tray.



                  Note


                  When replacing a failed fan tray in a running system, be sure to promptly replace the fan tray.



                  Tip


                  If one or more fans fail within a fan tray, the Fan Status LED turns red. A fan failure could lead to temperature alarms if not corrected immediately.


                  The fan status is continuously monitored by the software. In case of a fan failure, the following actions occur:

                  • System messages are displayed.
                  • Call Home alerts are sent (if configured).
                  • SNMP notifications are sent (if configured).

                  Each of the three fan trays cover two fabric modules as follows:

                  • Fan tray in slot 41 covers the fabric modules in slots 21 and 22.
                  • Fan tray in slot 42 covers the fabric modules in slots 23 and 24.
                  • Fan tray in slot 43 covers the fabric modules in slots 25 and 26.

                  If you need to replace a fabric module, you must remove the fan tray covering the fabric module before you replace the fabric module. You must replace the fabric module and its covering fan tray within three minutes or an overtemperature condition can occur.

                  To display the fan module statuses, see Displaying the Status for the Fan Trays.

                  Displaying the Status for the Fan Trays

                  To display the status for the fan trays, use the show environment fan command as shown in the following example.

                  Enter the show environment fan command.
