Zeroization
Caution! The Zeroization function can delete all IOS and configuration files on the system!
Zeroization should only be enabled if it is intended to be used.
Enabling Zeroization for the Cisco 5915 (ROU)
Prior to applying the zeroization signal, the Cisco IOS must be configured to enable zeroization.
From an IOS prompt, enter the following commands:
Router> enable
Router# conf t
Router(config)# service declassify erase-all
Router(config)# exit
The “
erase-all
” argument will erase all files on the router (flash and NVRAM) when
declassification (zeroization) is invoked
“
erase-flash
” or “
erase-nvram
” may be substituted for “erase-all” if only the files in flash memory
or NVRAM, respectively, are to be deleted.
Enabling Zeroization for the Cisco ESS2020 (SWI)
From an IOS prompt, enter the following commands:
Switch> enable
Switch# conf t
Switch(config)# service declassify erase-flash
Switch(config)# exit
Switch#
Initiating Zeroization
Caution! Triggering zeroization from either ring (ROU or SWI) will cause the entire system to be
zeroized.
If you only want to zeroize one system, ensure that zeroization is enabled on only that ring
– see
above.
The hardware setup must generate the off-board Zeroization trigger. Zeroization is triggered by pulling the
zeroize signal low (0v).
If you have CBL-2419-01, trigger zeroization by connection the yellow wire (zeroize) to the green
wire (ground).
J9 can also be used to trigger zeroization by connecting J9 pin 5 (ground) to J9 pin 9 (zeroize)
Caution! This differs from the MAR-5915-0x and -1x systems.
The -0x and -1x systems require 12v to trigger zeroization
DO NOT
apply 12v to the zeroize signal on MAR-5915-2x or system damage may occur.
Caution! If zeroization is enabled use J9 as a console with caution.
Inadvertant zeroization is possible if a J9 connected cable grounds J9 pin 9.
