Add power module and battery module to Symmetra LX

[Anonymous user]

I am going to add a power module and battery module to my Symmetra LX. This will take me from a 12kva to a 16kva and will fill up the battery slots. My question, this process is all hot swappable, right? I can just slide in my new power module and battery? I've got a SAN attached to the UPS and don't want to take a chance on it powering down.

Thanks....

So I can swap out bad moudules and batteries without having to to the UPS on BYPASS? We have an extended run cabinet connected to the mainframe and when we pulled a set of batteries out of them... it took the load down. Is there a procedure to doing hot swaps? I wish the user manual had this info.

There is no procedure for hot swapping modules. You just take them out. Removing batteries would not bring your load down. The only thing that potentially could bring your load down is either removing both of the intelligence modules when the UPS is online (it needs at least one working IM installed to be online) or if you remove too many power modules, forcing the unit to switch over to bypass, but your input voltage is out of range for bypass so it drops.

The only way I could see batteries affecting your load is if the UPS is running on battery and you suddenly remove the batts, thus removing the power source.

Thanks for the response... actually my customer were the ones who pulled out the batteries. And when that did they told me it took their load down. At the moment they have one bad Power Module and one bad battery on their extended run cabinet. The batteries they pulled out happen to be good batteries... they pulled out the wrong batteries may have been the cause of their load going down. Not sure??? In any case once they purchase the bad power module and battery replacing them should be a simple task! Thanks again!

Yeah, who knows what customers are doing! 😉 Hopefully they'll have better luck installing the new modules... They don't have to go to bypass, but if they feel safer that way, they can use the maintenance bypass switch to the right of the display.

After their mishap I believe going on Maintain Bypass is what they will do. Thanks again!

as techie mentioned, you don't need to take the load down. upon inserting modules, there is nothing you need to worry about. when you are removing them, thats when you need to make sure you have adequate redundancy so that the UPS doesnt get overloaded and go to bypass. also, with the batteries, if you remove them all, you will have no battery back up.
