3810m Flex Module

[cobis]

Is it safe/correct procedure to install a flex module in a 3810m switch while it is powered on?  Or must it be powered off?

I have a 4-port 10Gbps flex-module that I need to install in a 3810m, but not sure if I must power off first.

Hi @cobis !

Here is the correct replacement procedure - https://support.hpe.com/hpesc/public/docDisplay?docId=a00026837en_us&docLocale=en_US

It says "The 3810M Flex Port Module is not hot swappable" so the switch must be powered off. Also, the module installation procedure https://www.arubanetworks.com/techdocs/hardware/switches/3810/IGSG/3810_igsg.pdf , page 40 lists explicitly  as last step "Power on the switch and make sure the module passes its self test" which normally is not the case with hot-pluggable and hot-swappable modules.
