WARNING NOTICE TO USER!   

Although preventative safety measures have been designed into Radial 
500 series products 

we strictly advise against hot-swapping modules

 

or plugging and unplugging them when the Workhorse or other 500 series 
rack is powered on. Hot swapping can cause connection sparks at the card-
edge connector that could send damaging transients to other equipment. 
This also greatly reduces the life span of the card-edge contacts. Damage 
due to hot swapping is not covered under warranty. There are no user 
serviceable parts inside.
