HOW IS THIS MEMORY WRITE PROTECTED? HOW IS THE MEMORY CLEARED?
PLANAR, POWEREDGE R610
System BIOS SPI Flash Software write protected
Not possible with any utilities or applications and
system is not functional if corrupted/removed.
LOM Conguration Data
Not explicitly protected but special applications
are needed to communicate through the LOMs to
reprogram this ROM.
Not user clearable
iDRAC6 Controller ROM
Protected permanently by hardware Not clearable
iDRAC6 Controller RAM
n/a iDRAC reset
System CPLD Requires special system-specic utility
Not possible with any utilities or applications and
system is not functional if corrupted/removed.
System CPLD It's not accessible Not clearable
iDRAC6 Express Internal
Flash
Writes are proxied through a temporary iDRAC
scratchpad RAM and not directly made from an OS or
OS application.
Not user clearable
System RAM OS control Reboot or power down system
TPM ID EEPROM
(Plug in module only)
HW read only Not - read only
TPM Binding EEPROM
(on China planar only)
Locked by BIOS from physical access by anyone after
boot
N/A - BIOS control only
iDRAC6 SDRAM n/a
AC cycle for BMC OS and reset / power off server for
VGA frame buffer
iDRAC6 FRU Writes controlled by iDRAC embedded OS EPPID is not clearable
iDRAC6 Boot Block
Flash
iDRAC embedded OS control of the write protection.
Not possible with any utilities or applications and
iDRAC does not function as expected if corrupted/
removed. Lifecycle log is clearable only in a factory
environment. SEL is user clearable.
Trusted Platform Module SW write protected F2 setup option
CHIPSET
CMOS N/A - BIOS only control
Planar NVRAM_CLR jumper or remove AC cord, remove
cover, remove coin cell battery. Wait for 30 seconds,
replace battery, cover, and then AC cord.
F2 system setup option to restore defaults
2.5" BACKPLANE OR 3.5" BACKPLANE
Storage Controller
Processor
Embedded rmware only writeable through controlled
iDRAC methods
Not possible with any utilities or applications and
backplane does not function as expected if corrupted/
removed.
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

HOW IS DATA INPUT TO THIS MEMORY?
PLANAR, POWEREDGE R610
Controller Conguration
Data
Loading ash memory requires a vendor-provided rmware le and loader program that is executed by booting
up the system from a oppy or OS-based executable (DUPs, Unied Server Congurator) containing the rmware
le and the loader. Storage adapters loaded with bad rmware will not provide storage controller behavior.
FRU Factory only. Not customer updatable.
Integrated Mirroring
NVSRAM
Embedded storage rmware controls this data
iDRAC6 Enterprise
VFlash
Preloaded media before installation, or remote out-of-band upload of user data (i.e., ISO images, les) or local
server read/write capability to use like a hard disk
