The flash card could be corrupt.  Contact TAC to get it RMA-ed.

When you plug the controller into an AC power source, the bootup script initializes the system, verifies the hardware configuration, loads its microcode into memory, verifies its operating system software load, and initializes itself with its stored configurations. Before performing this test, you should have connected your PC to the CLI console on the controller as described in the "Connecting the Controller Console Port" section.

Please have a look into the below link

You should use Console port of 2500 to directly connect with the system and power on and follow the interactive script which appears on startup. IF still you are having issue even after reboot the Controller then you just change the Controller mode to ROMMON and reload the Controller image.
