FUNCTIONAL DESCRIPTION
The DuraNET 30-2020 is an ultra-rugged 19-port Cisco IOS-managed Layer 2 network switch integrating
Cisco’s ESS 2020 Embedded Services Switch technology with an isolated MIL-STD-1275/704 power
supply in an IP67 (dust/water proof) sealed aluminum chassis with MIL-DTL-38999 connectors. Designed
to optimize Size, Weight, Power and Cost (SWaP-C) in sensitive harsh military and civil environments
(i.e., aircraft, vehicle, mining, industrial), the unit provides reliable local area network (LAN) switching
capabilities with the ease-of-use, secure access, and manageability expected from Cisco-based
technology. Two levels of Cisco IOS software (LAN Lite or LAN Base) are available to support access
layer connectivity and needs for data, security, voice, and video traffic at the network edge for stationary
or mobile network nodes. Administrators can easily configure features, monitor performance, and
troubleshoot using a standard web browser or built-in command line interface (CLI).
An ideal solution for IP networking technology refresh and situation awareness applications, the DuraNET
30-2020 enables IPv4 and IPv6 devices (computers, cameras, sensors, routers, etc.) to be networked
across extended operating temperature ranges (-40 to +85C) and extreme shock/vibration conditions.
The unit is qualification tested to extreme MIL-STD-461F, MIL-STD-810G, and DO-160G thermal, shock,
vibe, humidity, contaminant ingress, and EMI/EMC conditions. To enhance reliability, the unit features no
moving parts, a near cableless internal design, industrial temperature grade components, EMI filtering,
and power protections for the voltage surges, spikes and transients of aircraft/vehicles.
Backwards compatible with the functionality and connector pinout of the DuraNET 2955, the DuraNET 30-
2020 provides an enhanced migration path for legacy deployed Cisco Catalyst 2955T-based switch
subsystems. Physical dimensions and weight are reduced, Ethernet port density is greater (2x GigE
uplinks plus 17x 10/100Base-T) and EMI/dust/water ingress and input power protections are improved.
The unit chassis is also modular in nature, enabling the potential for special factory-configured multi-
function appliances integrating Parvus DuraMAR 5915 Cisco IOS mobile router and/or Parvus DuraCOR
80-40 Corei7-based mission computer subsystem in the same chassis.

B REAKOUT C ABLE S ET
You can test the DuraNET 30-2020 interfaces and cabling prior to installation in the target system to
ensure full operational capability. Full bench-top testing can be performed by using an appropriate cable
set for this system. CBL-DUNET-30-2020-00 (electroless nickel 38999 finish) or -10 (olive drab 38999
finish) is available for purchase from Parvus to support lab or bench testing purposes. You can also
create a custom set of cables made specifically for the intended target system, vehicle, or craft; refer to
Chapter 3 for connector pinouts and descriptions.
For those customers who are using the DuraNET 30-2020 as a replacement to the DuraNET 2955, the
DuraNET 2955 cable set (CBL-1538-01) or the existing platform can be utilized; however, only ports 1
through 12 of the seventeen 10/100Base-T ports will be available.
The cable set (shown in Figure 4) includes the following cables:

P OWER - ON S EQUENCE
To configure the DuraNET 30-2020, you need a serial connection to the J5 Console port. This requires a
computer with a standard DB-9 RS-232 serial port and a terminal emulator PC application.
Follow these steps:
1. Connect a power cable to port J4 on the DuraNET 30-2020 (use CBL-1557-02 from the starter cable
set, or an equivalent MIL-DTL-38999 power cable).
2. Connect the other end of the power cable to the unpowered DC power.
Caution! Make sure that the DC power source is set to provide 6 to 36VDC.
3. Connect a serial cable to the standard 9-pin serial port on the host PC and to either J1 or J5.
•To use the J1 console, connect CBL-1554-02 from the starter cable set, or an equivalent MIL-
DTL-38999-to-DB-9 adapter cable. Connect the other end to port J1 on the DuraNET 30-2020.
•To use the J5 console, remove the cover plate over connector J5. Save the cover and screws; J5
should be covered when not in use. Connect CBL-1536-01 to J5 and the host serial port.
Caution! Do not connect to both console ports at the same time.
J1 Console and J5 Console are the same port. Connecting to both ports will result in an electrical
conflict on both connections.
4. Open a terminal emulator on the host PC.
5. In the PC terminal emulation software, configure the serial port for 9600 bits per second, 8 data bits,
no parity, 1 stop bit, and no flow control.
6. Apply power.
7. Use the command line interface (CLI) to enter commands to configure the switch. See the software
configuration guide and command reference from Cisco for more information (refer to the next section
on Switch Configuration).
8. Connect Ethernet devices to J1, J2, and/or J3.
Note: To prevent the user from interchanging cables for J1 and J2, the connectors and associated
cables are keyed differently.
•Use CBL-1554-02 to connect Gigabit Ethernet port 1 on J1.
•Use CBL-2549-01 to connect Gigabit Ethernet port 2 and/or 10/100Base-T port 17 on J2.
•Use CBL-2500-01 to connect the sixteen 10/100Base-T ports on J3.

SWITCH CONFIGURATION
The DuraNET 30-2020 Ethernet Switch is shipped with a Cisco factory-installed IOS.
Custom network configuration is the responsibility of the customer. Please refer to Cisco Embedded
Service 2020 Series Switches Software Configuration Guide for further information. The document may
be downloaded from the Cisco website at www.cisco.com.
MOUNTING THE DURANET 30-2020
After testing is complete, you can mount the DuraNET 30-2020 vertically or horizontally.
T HERMAL C ONSIDERATIONS FOR C HOOSING A M OUNTING L OCATION
The DuraNET 30-2020 enclosure is highly efficient at removing heat from the inside of the unit to the
outside of the finned enclosure. It is best to mount the unit on a thermally cool, thermally conductive
location to keep the overall temperature as low as possible. Every effort has been made to meet
stringent thermal performance criteria as outlined in the specifications. However, it is always good
practice to keep the DuraNET 30-2020 as cool as possible, avoiding external temperature environments
which will not allow the thermal conduction of heat away from the unit.

V ERTICAL M OUNTING
To install the DuraNET 30-2020 on a mounting surface:
1. Create a hole pattern on the mounting surface that matches the pattern shown in Figure 5. The
mounting holes are 0.27” in diameter.
2. Attach the baseplate to the mounting surface using the four mounting holes. Attachment screws
should be 1/4-20.
Important!
Ensure that mounting screw length allows proper thread engagement of the mounting hardware.
