how to replace cache battery in HSG80

I have a HSG80 controller with an expiring external cache battery. I've
ordered and received a replacement battery, but I'm not exactly sure what
procedure I need to do to install it. My system has a single HSG80
controller and a model 2200 enclosure. From the HSG80 Array Controller
Maintenance and Service guide, it shows that there are 2 cache modules for
each controller. In my case, I only have one controller so only one of
the caches is used. My question is do I simply put the new battery in the
cache A2 slot (next to the existing battery) ? Can I do this while the
system is running or do I need to halt everything first ?

Thanks for any help,

Dirk
