How is this memory write protected? How is the memory cleared?

Control Panel

Internal USB OS control. OS control format.

Internal SD Module Only by SD card write-protect switch. OS control format.

Power Supply

PSU Microcontroller

Protected by the embedded

microcontroller. Special keys are used

by special vendor-provided utilities to

unlock the ROM with various CRC

checks during load.

N/A—not in-system clearable.

PERC 6/i Integrated

PERC NVSRAM

Config Data

Storage controller firmware accessed

only.

N/A—not in-system clearable.

PERC Firmware

Write control access by storage

controller firmware.

N/A—not in-system clearable.

PERC Cache RAM

Storage controller firmware accessed

only.

Storage controller firmware clearable only.

Remove AC AND deplete or remove backup

battery.

FRU

Protected in that no iDRAC-

embedded firmware writes to this

device. Although very convoluted,

theoretically, IPMI I2C Master write

commands would flow through to

overwrite this EEPROM.

N/A—not in-system clearable.

IBUTTON Key

EEPROM

SHA1 encryption included. Storage

controller use only.

N/A—not in-system clearable.

CPLD Only factory programmable. N/A—not in-system clearable.

SAS 6/iR Integrated

Controller

Configuration Data

Write control access by storage

controller firmware.

N/A—not in-system clearable.

FRU

Protected in that no iDRAC-

embedded firmware writes to this

device. Although very convoluted,

theoretically, IPMI I2C Master write

commands would flow through to

overwrite this EEPROM.

N/A—not in-system clearable.
