Supervisor Modules Overview

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

  • Supervisor 2 Enhanced (N77-SUP2E)

  • Supervisor 3 Enhanced (N77-SUP3E)

Managing Cisco Nexus 7706 Hardware Installation - De switch beheren [Cisco Nexus 7000 Series-switches] (6)
Observation

You can use only one type of supervisor module on a switch.

When a switch has two supervisors, one supervisor automatically wakes up while the other is in standby mode. If the active supervisor fails or goes offline to replace it, the standby supervisor is automatically activated. If you need to replace one of the two installed supervisor modules with another module, you can do so without interrupting operations: the supervisor you do not replace becomes the active supervisor and retains the kickstart configuration while it replaces the other supervisor.

If the switch has only one supervisor, you can install the new supervisor in the supervisor slot opened during operation and activate this supervisor after installation.

Supervisor modules are automatically activated and started by the switch.

Exit a supervisor module

To exit a supervisor module, use themodule out of order command to specify the chassis slot with that module.

Procedure

Paso 1

Start configuration mode by entering theconfigure terminal command.

Example:

change#configure terminalchange (settings) #
Paso 2

Clear module configuration

You can clear the running configuration of a nonfunctioning I/O slot by using thepurification module Command in EXEC mode.

Managing Cisco Nexus 7706 Hardware Installation - De switch beheren [Cisco Nexus 7000 Series-switches] (8)
Observation

This command does not work on supervisor slots or I/O slots that currently have a module enabled.

Before you start

Verify that the I/O slot is empty or that the I/O module installed in the slot is disabled.

Procedure

Clear the active configuration using the purification module slot_number running-config command.

Example:

change#Purge module 1 running configuration

Example

Assume that 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 no longer need the IP address. If you attempt to configure this unused IP address, an error will occur, preventing you from continuing with the configuration. In this case you need thePurge module 3 running configuration Command to clear the previous configuration on Switch A before using the IP address.

Delete or enable an I/O module

You can shutdown or start an I/O module using theshutdown moduleofwithout shutdown moduleCommand to specify the module based on the slot number in the chassis.

Fabric module support overview

This switch supports the following fabric modules:

  • Sustancia 2 (N77-C7706-FAB-2)

  • Sustancia 3 (N77-C7706-FAB-3)

Managing Cisco Nexus 7706 Hardware Installation - De switch beheren [Cisco Nexus 7000 Series-switches] (9)
Observation

You can replace a Fabric 2 module with a Fabric 3 module during operations, but even though there is a mix of Fabric module types, all Fabric modules will function as Fabric 2 modules. If you reload a switch with Fabric 2 modules and Fabric 3 installed, only Fabric 3 modules will be enabled. To use Fabric 3 module capabilities, all installed Fabric modules must be Fabric 3 modules.

Change the amount of power reserved for fabric modules

By default, each switch reserves enough power for the maximum number of fabric modules that can be installed in the chassis. If you have fewer fabric modules installed than the maximum number and need to release unused spare power for I/O modules, you can disable unused slots and specify a lower maximum number of modules.

Use the hardware fabrics max number command to specify a different maximum number of fabric modules for your system. To check the status of installed fabric modules, use thexbar toon module domain. Use to check the amount of reserved powershow environmental strength command.

Before you start

  • Make sure the fabric modules you are using are installed in slots 1 throughXWhereXis the new maximum number of powder modules.

    You do not have to fill all the fabric slots, but the fabric modules you install must be in slots 1 throughX. For example, if you specify 4 as the new maximum number of fabric modules, make sure that the fabric modules you use are in slots 1 through 4.

  • Make sure each of the installed fabric modules is enabled using thegreen shutdown xbarslot_number command (seeExit or start a fabric module).

  • Disable unused slots using thedisable xbar slot_number command (seeExit or start a fabric module).

Procedure

Paso 1

Start configuration mode by entering theconfigure terminal command.

Power Modes Overview

You can configure one of the following power modes to use the combined power provided by the installed power supplies (without power redundancy) or to provide power redundancy when there is a power outage:

combined mode

This mode allocates the combined power of all power supplies to active power for switching operations. This mode does not allocate standby power for power redundancy in the event of power outages or power failures.

Power supply (norte+1) redundancy modes

This mode assigns a power supply as a backup power source in case an available power supply fails. The remaining power supplies are assigned based on available power. The backup power source must be at least as powerful as any power source used for available power.

Input source (network) redundant mode

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

full redundancy mode

This mode supplies power (norte+1) and input source (network) redundancies. Similar to input supply redundancy mode, this mode assigns half of the power supplies to provide available power and half of the power supplies to provide standby power. Alternatively, one of the backup power sources can be used to provide power if a power source supplying available power fails.

Guidelines for Configuring Power Redundancy Modes

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

combined mode

The available power is equal to the combined power of all installed power supplies. There is no standby power. You activate this mode using thecombined power redundancy mode command.

Power supply (norte+1) redundancy modes

The power supply producing the most power supplies backup power so that it can take over from any other power supplies that fail, and all other installed power supplies supply available power. This power mode is activated by theps-redundant power redundancy mode command.

Input source (network) redundant mode

Available power is provided by one power source and standby power is provided by the other power source. If the power source that supplies the available power fails, the switch uses the backup power source to provide the power it needs. This power mode is activated by theinsrc_redundant power redundancy mode command.

full redundancy mode

Full redundancy provides both power redundancy and input source redundancy. For power supply redundancy, the power supply with the highest output provides standby power and the other power supply provides available power. For input source redundancy, available power is provided by one power source and standby power is provided by another power source.This power mode is activated by theredundant power redundancy mode command.

Set power mode

You can set the power mode using thepower redundancy mode command.

Paso 2

Specify one of the following power modes by pressing thepower redundancy mode way command:

  • For combined mode, add theset keyword.

  • For power supply redundancy mode, take theps-redundant keyword.

  • For input source redundancy mode, take theinsrc_redundant keyword.

  • For full redundancy mode, get theunnecessary keyword.

Observation

A combination of 3 kW DC and 3.5 kW HVAC/HVDC power supplies can be used.

Fan Trays Overview

From Cisco-Nexus7706The switch supports two types of fan trays:

  • 38mm Gen 1 loaded fan (N77-C7706-VENTILADOR)

  • 76mm Gen 2 fan loaded (N77-C7706-VENTILADOR-2): Use this fan tray to comply with Network Equipment Building System (NEBS) when using the Cisco Nexus 7700 M3 Series 12-Port 100 Gigabit Ethernet I/O Module (N77-M312CQ-26L)del módulo de I/S Cisco Nexus 7700 series F4 of 30 ports and 100 Gigabit Ethernet (N77-F430CQ-36)is installed on the switch.

Managing Cisco Nexus 7706 Hardware Installation - De switch beheren [Cisco Nexus 7000 Series-switches] (14)
Observation

During normal switch operations, all 3 fan trays in a switch must be of the same type.

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

  • One or more fans fail in a fan tray: Even with multiple fan failures, the switch can continue to function. When a fan in a drawer fails, the operating fans in the module increase their speed to compensate for the failed fans. If a fan fails, the faulty fan must be replaced.

    The following is sample output showing a fan failure along with associated system logs:

  • Fan tray is removed for replacement: The fan tray is designed to be removed and replaced while a switch is operating without creating an electrical hazard or damaging the switch.Since Cisco NX-OS version 7.2(0)D1(1), use elhardware fan tray maintenance mode[language|half|Map]command to put the switch in fan tray maintenance mode in preparation for fan tray removal and replacement. For more information, seeFan tray maintenance mode.You have up to 72 hours to replace a fan tray as long as the switch inlet air temperature does not exceed 30°C (86°F). If the temperature exceeds 30 °C (86 °Fahrenheit), the switch will turn off after 3 minutes.
    Managing Cisco Nexus 7706 Hardware Installation - De switch beheren [Cisco Nexus 7000 Series-switches] (15)
    Observation

    The switch turns off like a Gen 1 mix (N77-C7706-VENTILADOR) and generation 2 (N77-C7706-VENTILADOR-2) the fan trays are present on the same switch for more than 21600 seconds (6 hours). The syslog message "PLATFORM-0-FAN_MISMATCH_TIME: Fan modules mismatch. Gen1 and Gen2 fans are present in the fan tray forseconds" is displayed at regular intervals when both Gen 1 and Gen 2 fan trays are present on the same switch.
  • If you remove more than one fan tray at a time, the switch can run for up to three minutes before turning off. Remove only one fan tray at a time to prevent it from shutting down.
    Managing Cisco Nexus 7706 Hardware Installation - De switch beheren [Cisco Nexus 7000 Series-switches] (16)
    Observation

    • We recommend not removing more than one fan tray at a time.

    • When a fan fails or you remove a fan tray, the remaining fans running are sped up to compensate for the loss of fans. This can increase fan tray noise until you either replace the missing fan tray or replace the faulty fan tray.

    • When replacing a faulty fan tray on an operating system, be sure to replace the fan tray immediately.

Caution

If one or more fans in a fan tray fail, the fan status LED turns red. A fan failure can cause temperature alarms if not corrected immediately.

The fan status is continuously monitored by the software. In case of fan failure, the following actions are carried out:

  • System messages are displayed.

  • Call Home alerts are sent (if configured). Consult for more informationAssociate an alert group with a destination profile.

  • SNMP notifications are sent (if configured). Consult for more informationEnable SNMP notifications.

    .

Each of the three fan trays covers two dust modules as follows:

  • The fan tray in slot 41 covers the dust modules in slots 21 and 22.

  • The fan tray in slot 42 covers the dust modules in slots 23 and 24.

  • The fan tray in slot 43 covers the dust 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 replacing the fabric module. You must replace the fabric module and the corresponding fan tray within three minutes, otherwise overheating may occur.
