Nexus 5548 adding layer 3 module



we have couple of Nexus 5548 which is working as layer 2


we have purchased layer three cards which are N55-D160L3-V2= (L3 daughter card version 2) which comes with licence file as well which is N55-LAN1K9


My question is that due to higher OS its hot swappable so we can add the card into the chassis


my second question is when we install the license do we have to do the reboot. Does license file needs a reboot to work???


i couldn't find this on cisco

The module does not support

The module does not support OIR so you need to turn off the appliance.  Once the module is installed, you need to enable the Layer 3 feature.

Hi Leo According to Cisco you

Hi Leo


According to Cisco you can if you have higher version of OS........Kindly advise now you have made me more confuse


I have taken this from the above link

Note Cisco NX-OS Release 5.0(2)N1(1) does not support the hot swapping of a Cisco Nexus 5548 expansion module during switch operations. Instead, you must power down the switch before removing and replacing an expansion module. If you are using NX-OS Release 5.0(2)N2(1) or later release, you can hot swap the expansion modules.

Hello, This note that you are



This note that you are referring to is for the expansion module, not for the I/O module, which the N55-D160L3-V2= is. The I/O module requires for the switch to be powered off...
