Hi,
We got many 2602 AP running under Controller mode. Every night Cisco Energywise turn the power off to these AP's and next morning turn it back on. But randomly in a month few AP fails to come back. When I check on console I see error - The system has encountered an error accessing flash during initializion. I re-inialize the flash using flash_init command and it boot's up perfectly without any problem.
AP Model - AIR-CAP2602I-Z-K9
AP Image - ap3g2-k9w8-tar.152-4.JB6
WLC SW Version - 7.6.130.0
Error Details:
IOS Bootloader - Starting system.
flash is writable
FLASH CHIP: Numonyx Mirrorbit (0089)
Xmodem file system is available.

Any idea why this happens, 5-7 AP fails every month.
