AP 2602 Error Accessing Flash during Initialization

[Sakun Sharma]

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.
Error accessing flash at 0xe8000000 with 32-bit reads [0xbfaaaaaa != 0xffaa6aaa]

The system has encountered an error accessing flash during initializion.  The following commands will
initialize the flash file system and finish
loading the operating system software:

    flash_init
    ether_init
    tftp_init
    boot

ap: flash_init

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

Sounds like you need to RMA this AP.

Unfortunately our AP's are not under RMA...!!

But after flash_init command on this, it's working fine without any issue.

Said who?  I've got  fleet of OLDER model AP1140 and I don't have any maintenance contract on them but I can RMA them if they are faulty.  

AP2602i/e model AP is covered under Cisco's Limited Lifetime Warranty.  If you can prove to Cisco Entitlements Team that you are the original purchaser of the AP you can RMA the AP.
