| Most UPS batteries aren't rated past 5 years - 9 years is really pushing it even for ones that have been probably maintained.
On the remote carrier setup there is a port on the LCI (local carrier interface) that is designed to interface with the host systems Sys monitor card - I have yet to see one actually hooked up and those are what generate the various PWR codes. Might want to look into this for the fiber setup and see if it applies. |
