I2C read from EEPROM device 0x51 failed

Platform: EX8216

Code: 15.1R6-S2.1

Description:

Master and Backup Routing-Engines is not fetching any outputs.

Customer performed format installation on both the REs.

During the boot process, chassis is recording below logs:

fdisk: invalid fdisk partition table found

Firmware Version: --- 03.04.00 ---

CPLD/FPGA image versions on the board:

GCBC FPGA = 05.04 | BTCPLD = 07

USB: scanning bus for devices... 2 USB Device(s) found

scanning bus for storage devices... 1 Storage Device(s) found

I2C read from EEPROM device 0x51 failed.

Is the I2C read is failing for the hard disk ?

Expectation:

I would like to learn on how to find which part of the chassis is 0X51.

From chassisd logs, I could see FPC0 and FPC15 online request is being rejected continuously.
