This article explains the procedure that should be followed to correctly shutdown/powerdown a Cisco Nexus 7000 series module and remove it from the chassis. We also include important tips that will help ensure you avoid common problems and mistakes during the removal procedure.
The Nexus 7010 is one of the larger data center switches in the Nexus portfolio found in most enterprise-class data centers. Even though the Nexus 7000 series switches have been in the market since 2008 there are still a lot of data centers powering their core infrastructure using the well-known Cisco Catalyst series.
The Nexus 7000 series switches are designed for continuous operation, which means all parts are hot-swappable thereby eliminating downtime for upgrades or parts replacement.
The process covered in this installation guide can be used with all Nexus 7000 series modules including:
- 48-port 10/100/1000 Ethernet module (N7K-M148GT-11)
- 48-port 10/100/1000 Ethernet module with XL option (N7K-M148GT-11L)
- 48-port 1-Gigabit Ethernet I/O module (N7K-M148GS-11)
- 48-port 1-Gigabit Ethernet I/O module with XL option (N7K-M148GS-11L)
- 48-port 1-/10-Gigabit Ethernet I/O modules with XL (N7K-F248XP-25 and N7K-F248XP-25E)
- 32-port 10-Gigabit Ethernet I/O module (N7K-M132XP-12)
- 32-port 10-Gigabit Ethernet I/O module with XL option (N7K-M132XP-12L)
- 32-port 1- and 10-Gigabit Ethernet I/O module (N7K-F132XP-15)
- 8-port 10-Gigabit Ethernet I/O module with XL option (N7K-M108X2-12L)
Step 1. Nexus 7000 Module Shutdown - Poweroff
The Nexus 7000 series modules are hot swappable and support automatic shutdown when ejected, however, it is always advisable to poweroff the module before removing it. If the module is to be removed or swapped with a different module type it is advisable to also ensure all configuration associated with the old module’s ports is cleared and ports are shutdown before the module is removed.
Locate the slot number of the module to be uninstalled and remove all attached cables. It is very important no cables are attached to the module and there is enough space on both sides of the module. In our example we’ll be removing the module located in slot No.9:

Issuing the show module 9 command will reveal the module’s model, status, capabilities, serial number and diagnostic status:
The output of the show module is also reflected on the module’s status LED. A green Status LED, as shown in the photo on the left, tells us that the module is currently online (powered on) and operating.
The orange interface LEDs confirm that the interfaces are in a shutdown state.
The specific card we are about to remove is a 48-port 10/100/1000 Ethernet card (N7K-M148GT-11L):
Now proceed to power off the module using the poweroff module 9 command:
