Change single blade B2100 in viprion chassis

If I want to change a SINGLE blade B2100 in active viprion chassis C2400, should I shutdown the active viprion chassis first before proceed to change blade? Or can I just change the blade without shut down the chassis? The viprion chassis is designed in HA mode.

if i were you, i would failover, shutdown only the blade i want to change and then change the blade. to shutdown specific blade, you just run halt or shutdown on bash of that blade.
