This Command will show you how many modules, what types of modules, Supervisor, and other
Hardware components are installed in this Nexus Box. It display information about the field
replaceable units (FRUs), including product IDs, serial numbers, and version IDs by entering the show
inventory command.

The Above output can also be found by giving the Show Module Command on the Nexus Box. This
Command provides the Module type / Module number Installed on the particular Slot and also provides
the Status and Physical address.

* this terminal session

Cisco Nexus 7000 Series switches support up to five fabric modules in the chassis. Each chassis has its
own type of fabric module as follows:

  • Cisco Nexus 7009 chassis uses the Fabric 2 (N7K-C7009-FAB-2) modules.
  • Cisco Nexus 7010 chassis uses the Fabric 1 (N7K-C7010-FAB-1) or Fabric 2 (N7K-C7010-FAB-2)
  • Cisco Nexus 7018 chassis uses the Fabric 1 (N7K-C7018-FAB-1) or Fabric 2 (N7K-C7018-FAB-2)
  • The Cisco Nexus 7004 switch does not include fabric modules.

If your chassis has more than one I/O module, you can check the progress by repeatedly using the show
module command and viewing the Status column each time.
The I/O module goes through a testing and an initializing stage before displaying an ok status Table
describes the possible states in which a module can exist.

Task 3: Connect to the Nexus 7000 series and determine the active supervisor.

Kernel uptime: 631 days, 16 hours, 43 minutes, 25 seconds
Active supervisor uptime: 631 days, 11 hours, 16 minutes, 8 seconds

To know about the active Supervisor, show redundancy status command provides you the details.

The Cisco Nexus 7000 Series switch has one or two supervisor modules. The switch can use the following
supervisor module types:

  • Supervisor 1 (N7K-SUP1)
  • Supervisor 2 (N7K-SUP2)
  • Supervisor 2 Enhanced (N7K-SUP2E)

Supervisor 1 modules are supported by the Cisco 7009, 7010, and 7018 switches, but it is not supported
by the Cisco Nexus 7004 switch. Supervisor 2 and 2E modules are supported by all Cisco Nexus 7000
Series switches.

Task 4: Connect to the Nexus 7000 series display system environment information.

Power Usage Summary:
--------------------
Power Supply redundancy mode (configured) PS-Redundant
Power Supply redundancy mode (operational) Non-Redundant
!
Total Power Capacity (based on configured mode) 12000 W
Total Power of all Inputs (cumulative) 12000 W
Total Power Output (actual draw) 2469 W
Total Power Allocated (budget) 5310 W
Total Power Available for additional modules 6690 W

This Second part defines the Total Power available and Power Consumption used by the each module.

  • Power supply redundancy mode is currently specified  ---- Power Supply Redundant
  • Module or modules draw the least amount of power --- Fabric Modules

Power Available by N7K-AC-6.0 KW Module is 6000 Watts Per Power Module So total Power available from all 3 power Unit is 18000W and actual Power output drawn is 2269W.

The Cisco Nexus 7000 chassis supports multiple load-sharing, fault-tolerant, and hot-swappable power supplies. As few as just one power supply can be used to operate a switch chassis. Use of multiple power supplies provides additional power capacity and resilience after failure of the power supply, the generating supply itself, or a facility component such as an uninterruptible power supply (UPS) or a circuit breaker.

Task 5: Connect to the Nexus 7000 series use the Display module system resources utilization.

Task 9 : Check How Locator Led Configured and how to verify the Locator Led

LED locator (Beacon) New hardware feature

  • Makes it easy to locate any hardware component for maintenance
  • Operated from default vdc only
  • Once turned on, stayes on till turned off

Cisco NX-OS software supports a Locator LED feature that is useful when physically identifying hardware components (chassis, fans, fabrics, modules, power-supplies) and ports on Ethernet I/O modules. The Locator LED feature should be used when working with remote-hands support teams that are responsible for performing physical tasks such as replacing hardware or working with Ethernet ports (adds moves, etc.). Use the no locator-led command to disable the locator LED for a chassis component or interface.

The Cisco NX-OS CLI syntax changed in Cisco NX-OS Release 4.1(2). The locator-led command replaced the deprecated blink command. Ethernet ports on an I/O module do not display their status in the output of the show locator-led status command. Use the show interface command or view the running-configuration to determine if a port Locator LED (Beacon) is enabled or disabled.

Here it is 10 Slot Chassis with 3 XBAR Modules.  Utilization% is calculated based on 138 GBPS (7*23G) overall capacity

Here As this Switch is 7010, and Solt 1,2,3,7,8, 9 has two Trace going towards 3X bar modules.

For Slot 1: There are 6 traces going to 3Xbar Modules (6*23 = 138 Gbps)

For Slot 2: There are 6 traces going to 3Xbar Modules (6*23 = 138 Gbps)

For Slot 3: There are 6 traces going to 3Xbar Modules (6*23 = 138 Gbps)

For Slot 5: There are 3 traces going to 3Xbar Modules (3*23 = 69 Gbps)

For Slot 6: There are 3 traces going to 3Xbar Modules (3*23 = 69 Gbps)

For Slot 7: There are 6 traces going to 3Xbar Modules (6*23 = 138 Gbps)

For Slot 8: There are 6 traces going to 3Xbar Modules (6*23 = 138 Gbps)

For Slot 9: There are 6 traces going to 3Xbar Modules (6*23 = 138 Gbps)
