[Star trek] What Powers all the non warp systems in a starship?

If the warp core powers the Warp engines, What powers the rest of the ship? Often times the warp core was taken off line for maintenance and the ship still functioned fine (without Warp capabilities). If the ships are powered by the core, how does the rest of the ship remain functional?

What's commonly called the "warp core" is actually the matter-antimatter reaction assembly. This is connected to the plasma grid, which distributes energy to the rest of the starship, not just the engines. The electro-plasma is bled off into canisters which form the basis of "auxiliary power" that the ship functions on when the warp core is offline. This system can also be used to boost power to certain systems while the warp core remains functional.

In addition to that, there are EPS taps which connect to standard batteries where electricity is stored. This is "emergency power", its main priority is for use when all other systems are offline to maintain life support and communications.
