It is normal. They don't have to so it's your problem if you want to. Their site spec docs probably say as much, AT&T's certainly did. Customer provides AC power or somesuch; that can be straight utility or off a UPS you maintain, but they're not going to maintain batteries for you if they don't have to. Some diverse ring OC-x that came with a DC battery plant where they were mandated to have X hours runtime on it is a different era than today's "toss an Ethernet switch on the end of some fiber" circuits. ~Seth

I have several clients who have cisco Metro Ethernet switches on Fiber circuits. The provider just provided the switch and expects the client to deal with the power. The rational is if the switch is not up it's not our fault.

We have tons of circuits with various providers. Often times the demarc / handoff switch from the provider is not running on battery backup. Sometimes if the demarc device is located in the same room as our equipment we mitigate this and plug the device into our backup systems.
