Can a UCS FEX be removed or added live?

CiscoMedMed

I am migrating from one FI pair to another. The current FI

pair has a 16 port FEX module in them. If I remove all the

Ethernet connection from them, can I remove the FEX

module from a currently running fabric interconnect? And

on the flip side can I insert a FEX into a running fabric

interconnect without causing a problem? 

 

NAME: "Chassis", DESCR: "UCS 6248 Series Fabric Interconnect"
PID: UCS-FI-6248UP , VID: V01 , SN: SSI17420XXX

 

NAME: "Module 2", DESCR: "O2 16 port flexible GEM"
PID: UCS-FI-E16UP , VID: V01 , SN: FOC18275XXX

Just to confirm, it sounds like you are referring to the GEM (gigabit ethernet module) module installed to the far right of the 6248 as opposed to a FEX (fabric extender) which is a separate physical switch?

 

If so, then yes, the GEM module is hot swappable, meaning it can be installed and removed without power off the fabric interconnect. As with any change, we always recommend conducting this install/removal during a scheduled maintenance window and conduct the change on a single fabric at a time.

Thanks much Wes for the reply and correcting my term for the additional ports. Yes it's the GEM.
