Zeroization
For data security, the DuraMAR 5915 provides zeroization capability to erase the application code and
configuration data stored in the system. Refer to the Cisco documentation on how to configure the 5915
for zeroization. Once the code is erased, the only method of recovery is to reload code to the system.
Enabling Zeroization in Cisco 5915 IOS
Prior to applying the zeroization signal, the Cisco IOS must be configured to enable the 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.
Initiating Zeroization
The hardware setup must generate the off-board Zeroization trigger.
If you have CBL-2419-01, use the yellow wire and apply a +12VDC signal pulse to J3 pin 2. The
green wire is the ground reference for the +12VDC signal.
If you do not have the starter cable, apply a +12VDC signal pulse to J3 pin 2.
Caution!
Do not apply +12VDC to any other pin. +12VDC must be relative to signal ground (J3 pin 1), not input
power ground.
Zeroization Recovery
After zeroization has been completed (about 5 minutes), perform the following steps to reload the system.
1. Start the Cisco console. Reload the Cisco 5915 IOS (refer to the instructions in the next section).
2. Reload the Cisco 5915 configuration. Refer to the instructions in the next section.
3. If your system contains an expansion module that supports zeroization (such as the COM-1268 EM),
you'll need to perform recovery for those boards. Refer to the addendum for your expansion module
for instructions on zeroization recovery.

Loading Cisco Files
This section explains how to load Cisco application and configuration files to the Cisco 5915. It covers
two cases: reloading after zeroization and upgrading to a new version.
This manual is not intended as a comprehensive guide to the Cisco 5915 or IOS. That information is
available directly from Cisco Systems at www.cisco.com.The Cisco website is also your source for Cisco
files.
Command Conventions
Commands and arguments you must type are shown in bold.
After you type the command, press the Enter key.
If several command lines are presented in one step, press Enter after each line.
Loading the IOS Image After Zeroization
Host PC Setup
1. Start the Cisco console.
2. Identify the target folder used by the tftp server and place the Cisco IOS software image there. The
DuraMAR 5915 ships with a factory default Cisco IOS version of:
c5915-entbase-mz.SPA.152-1.GC1.bin
3. Place the configuration file to be reloaded (c5915-entbase-mz.SPA.152-1.GC1.bin or other) in the tftp
target folder.
4. Attach the host PC to port 0/0 on J2. (This can be the same PC as that running the terminal
emulator.)
5. Set the IP address of the host PC to use the fixed address 192.168.100.11.
6. Open the tftp server on the host PC.
A note on this: The Solarwinds TFTP server has a file transfer size limit of 32 MB. This is
not a problem for the base IOS identified here. But if the c5915-adventerprisek9-
mz.SPA.152-1.GC1.bin or another file in excess of 32 MB is transferred, the file is too large
for Solarwinds. The TFTPD32 TFTP server handles the larger file size without a problem.
Load Procedure
There should be a rommon prompt in the terminal emulator window. If the rommon prompt is not
displayed, reboot the DuraMAR 5915 and wait for the rommon prompt.
1. At the rommon command prompt, type the following CASE-SENSITIVE commands (press Enter after
each command, the filename itself is NOT case-sensitive):
IP_ADDRESS=192.168.100.10
IP_SUBNET_MASK=255.255.255.0
DEFAULT_GATEWAY=192.168.100.11
TFTP_SERVER=192.168.100.11
TFTP_FILE=c5915-entbase-mz.SPA.152-1.GC1.bin
2. At the rommon command prompt, type “set” and Enter. Verify the variables in step 1 have been set
correctly.
3. At the rommon command prompt, type the following CASE-SENSITIVE command and Enter:
tftpdnld

4. At the prompt: “Do you wish to continue y/n: [n],” type y.
5. The IOS will begin transferring to the Cisco 5915. If the transfer does not begin, a message will be
displayed explaining the problem. Fix the problem and repeat the tftpdnld command.
6. When the file transfer is completed, issue a reset command at the rommon prompt.
7. The Cisco 5915 will then reboot and load. After the Cisco 5915 has finished the startup sequence,
press Enter to display the Router> prompt. The Cisco IOS has been successfully reloaded.
8. Now follow the instructions in the next section to reload the IOS configuration.
Loading the IOS Configuration After Zeroization
After zeroization, you have to reload the IOS configuration file that enables communication between the
Cisco boards and the COM-1268s. In these instructions, filename is the name of the IOS configuration
file saved on the host PC, such as 5915config.bin. If you are using a different file, use that filename in the
steps below.
1. Set the router port IP address:
Router> enable
Router# conf t
Router(config)# Interf fast 0/0
Router(config-if)# ip address 192.168.100.10 255.255.255.0
Router(config-if)# no shut
Router(config-if)# exit
Router(config)# exit
Router# copy tftp://192.168.100.11/filename startup-config
Destination filename [startup-config] ?
2. Make sure that the [ok- xxxx bytes] message is displayed. If not, fix the error and repeat the copy tftp
command.
3. Power off the system.
4. Power on the system.
5. After the reload completes, press Enter to display a Router> prompt. The Cisco 5915 IOS
configuration has been successfully reloaded.
6. If your DuraMAR 5915 includes expansion modules, you may need to perform additional recovery
steps. Refer to "Zeroization Recovery" instructions in each addendum.
