Preface
This user’s Manual is applied to the MILTECH-9012C/G Full Layer 3 Ethernet switch with a computer running Linux.
This document describes how to install and use the MILTECH-9012C/G, which was designed for easy installation
and high performance.
Product Overview
The MILTECH-9012C/G is specifically designed for battlefield C4ISR, voice, video, sensor data acquisition and
communications in platforms that require LAN/WAN connectivity.
While platform-internal networks need maximum speed and throughput, WAN interfaces require robust connectivity.
The MILTECH-9012C/G provides the best of both worlds in a single package - with Milpower Source’s proven line-
rate internal routing/switching AND Cisco-IOS industry-standard routing, security, and mobility protocols.
The MILTECH-9012C/G’s switch portion features both L2/L3 network switching and routing capabilities, including
virtual LANS (VLANS), traffic prioritization/QoS, IPv4/IPv6 support, and bandwidth aggregation.
The integrated Cisco ESR router transparently connects to a mobile world of wired and wireless networks, with
IPv4/IPv6 routing and multicast protocols that include BGP, OSPF, GRE, EIGRP, CDP, IGMP and MLD. Voice and
video connection quality is maintained with advanced quality of service (QoS) while external communication is
secured with the latest encryption algorithms, IPsec and IKEv2 protocols, authentication, identity management, and
integrated threat management. These advanced functions normally require a separate edge router, but are now
available in Milpower Source’s compact MILTECH-9012C/G.
The MILTECH-9012C/G offers the best combination of size, weight, and power (SWaP) in the industry, saving
valuable real estate for devices that make mobile platforms highly effective. No other military-grade device offers
such functionality in such a small package.
The 9012C is a member of the MILTECH9012 family that offers flexible alternatives for LAN, LAN/WAN, and
customizable networking. All family members are MIL-STD, fully managed, and military grade, with 12 triple-speed
(10/100/1000Mbps) ports.
The MILTECH-9012C/G gigabit-rate transmission and 24VDC power make it instantly compatible with any network
device and power systems.
Developed for military and harsh avionic applications, the MILTECH-9012C/G’s mechanical packaging
enhancements are designed for MIL-STD-810 airborne and ground environmental compliance and high reliability.
The unit has been especially hardened to improve ingress, impact, and shock/vibration protection, as well as
eliminate all moving parts through the use of passive cooling. Sealed SCE2 Amphenol circular connectors gives
the 9012C/G an IP67 rating.
Features Overview
•12 x triple-speed (10/100/1000Mbps) managed ports
•Full Cisco IOS –5921 Router, ESR (optional)
•Both L2/L3 network switching and full routing capabilities
•Only 1.1Kg to offer the best performance and combination of size, weight, and power
•Operating at extreme temperature of -45°C to +85°C
•Meets the toughest industrial and military environments such as MIL-STD-810F, MIL-STD-461E,
Test Reports are available upon request.

Cisco 5921 Router topology
The MILTECH-9012C system is using a COMe-SBC (computer) which is running Linux and the
Cisco Router 5921 IOS Version 15.6(3)M1 or later
Cisco application is installed in the following directory: /opt/cisco/c5921/
The Linux Interface Eth2 is associated to Cisco Fast Ethernet 0/1. This port is attached to External
Port #12.
The Linux Interface Eth3 is associated to Cisco Fast Ethernet 0/0. This port is the internal
connection between the Ethernet switch (port #12) and the CPU/COMe-SBC.
The Cisco IOS Ethernet port 0/0 is configured with 11 sub interfaces, Ethernet 0/0.1 ~ 0/0.11
Each one of the sub interfaces is associated to a different VLAN (1-11).
Each sub interface is holding an IP address which is the default gateway to its specific VLAN
devices:
Sub interface Ethernet 0/0.1= VLAN1 = 192.168.101.1
Sub interface Ethernet 0/0.2= VLAN2 = 192.168.102.1
Sub interface Ethernet 0/0.3= VLAN3 = 192.168.103.1
Sub interface Ethernet 0/0.4= VLAN4 = 192.168.104.1
Sub interface Ethernet 0/0.5= VLAN5 = 192.168.105.1
Sub interface Ethernet 0/0.6= VLAN6 = 192.168.106.1
Sub interface Ethernet 0/0.7= VLAN7 = 192.168.107.1
Sub interface Ethernet 0/0.8= VLAN8 = 192.168.108.1
Sub interface Ethernet 0/0.9= VLAN9 = 192.168.109.1
Sub interface Ethernet 0/0.10= VLAN10 = 192.168.110.1
Sub interface Ethernet 0/0.11= VLAN11 = 192.168.111.1
The configuration is following Cisco recommendation for Router on a stick topology.
Default IP Address
oThe IP address of the Cisco IOS eth0/1 (External Port #12) on the cisco is 192.168.2.140
with subnet musk 255.255.255.0.
oInterface Eth1/0 is used to communicate with the Linux TAP0 interface, in order to have full
communication between the Cisco Router and any Linux application. The Cisco Eth1/0 IP
address is 192.168.150.155. The Linux TAP0 interface IP address is 192.168.150.150.
Subnet Mask for both interfaces is 255.255.255.0.
oWe have also configured IP address to the Linux interfaces. The Cisco Router is ignoring
these IP address, but if you wish to have connectivity to the Linux or have any direct
operation to the Linux you can access it via the below IP address:
oLinux IP address of Eth2 (External Port #12) = 192.168.0.115, 255.255.255.0
oLinux IP address of Eth3 (Internal Port to the Ethernet-Switch) –192.168.1.115,
255.255.255.0

SBC Software requirements
1. OS - The SBC is running Linux CentOS 6.5 with most updated released packages.
a. The Linux OS is running from Virtual partition which is Read ONLY, so, during boot and operational
mode during power shutdown system files will not be damaged, and the OS is stable for any power
cutoff.
b. No option to write to the OS partition.
2. Read / Write Directory - If you need to provide constant Write/Read privileges to a specific directory, you
need to add the path of this directory to: nano /etc/rwtab
3. Enable / Disable of Read Only protection
a. The system will allow to change the write protection to R/W permission by typing the commands:
i. "nano /etc/sysconfig/readonly-root"
ii. R/W Permission - change READONLY to no: "readonly=no"
iii. R Only Permission - change READONLY to yes: "readonly=yes"
4. GPI/O - The system supports 4 GPI and 4 GPO with the below commands:
a. Port #10 –4 x GPI, Port #11 –4 x GPO, in the 9012C unit
b. GPI/O Driver location: /Unified_PET/PET_API/Linux/x86/release

6. SBC Reset Functionality –The SBC will reset/reload via the reset PINs.
a. Port #3 in the 9012C unit
b. Reset behavior:
i. Momentary connection of the Reset PIN - Mto the GND PIN - Lwill initiate graceful
shutdown to the whole system –Switch and SBC, until all LEDs and power are off.
additional momentary connection of these PINs will power the system up.
ii. Long connection of these PINs –over 3 Sec will do force shutdown for the whole system –
SBC and Switch. After this operation you will need to disconnect the power and connect
again to power the unit up again.
