MOUNTING THE DURANET 20-11
After testing is complete, you can mount the DuraNET 20-11 vertically or horizontally.
THERMAL CONSIDERATIONS FOR CHOOSING A MOUNTING LOCATION
The DuraNET 20-11 enclosure is highly efficient at removing heat from the components inside of the unit
to the case. The highest power consumption components are heat sunk directly to the bottom of the unit
where it is expected to be mounted. 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 20-11 as cool as possible, avoiding external temperature environments
which will not allow the thermal conduction of heat away from the unit.
MOUNTING
To install the DuraNET 20-11 on a mounting surface:
1. Create a hole pattern on the mounting surface that matches the pattern shown in Figure 6.
2. Attach the baseplate to the mounting surface using the four mounting holes. Attachment screws
should be 6x32.
Important!
Ensure that mounting screw length allows proper thread engagement of the mounting hardware.

CHAPTER 3 MANAGEMENT INTERFACE DESCRIPTION
The DuraNET 20-11 management interfaces provide the network administrator with a set of
comprehensive management functions. The network administrator has a choice of two easy-to-use
management interfaces:
 Serial CLI (command line interface)
 Manages all switch features, including CLI enhancements.
 Must be used to change the switch IP address from the factory default.
 Can be used even if there is no network connectivity.
 Provides brief help on syntax for each command.
 Web GUI (graphical user interface)
 Manages all switch features except the switch IP address and CLI enhancements.
 Requires network connectivity.
 Provides extensive help on functions and parameters.
For centrally managed networks, the switch also supports SNMP Management (not described in this
manual).
This chapter explains the switch configuration files that store switch parameters, and then provides step-
by-step quick starts for each of the interfaces. The CLI is described in detail in Appendix A. The
Software User’s Manual for the switch describes both interfaces in detail, and is available for download
from the Parvus site.
Note: If the Software User's Manual is not available, use the GUI's extensive help system.

USING THE CLI
This section describes basic usage and configuration of the command line interface (CLI) for the
DuraNET 20-11.
The CLI interface is an industry-standard CLI and consists of configuration commands which provide the
ability to configure and view the configuration using the serial console, or Telnet or SSH access. Even if
there is no network connectivity, you can still manage the switch using a serial connection.
SERIAL CLI SETUP
1. Connect the DuraNET 20-11 to a serial port on the host PC.
2. Power-on the DuraNET 20-11.
3. Open a terminal emulator on the host PC, such as TeraTerm or PuTTY on Windows, or Minicom on
Linux.
4. In the PC terminal emulation software, configure the serial port to 115200 baud, 8 data bits, 1 stop bit,
no parity, no flow control.
CLI QUICK START
The instructions in this section provide step-by-step instructions on how to use some of the CLI
commands.
Remember that bold identifies what you should type exactly as shown; bold italic marks a parameter
you should provide, such as <address>.
Log In
When the card powers on, the switch boots through RedBoot to the switch CLI and the following
messages are displayed on the console:
RedBoot> go
Parvus version 1.X.X
Press ENTER to get started
1. Press Enter one or more times until the Username: prompt appears.
Username:
1. Type admin and press Enter.
Username: admin
Password:
2. At the Password prompt, press Enter. (There is no default password.) This completes the login
sequence. The prompt changes to SWITCH-XXXX#, where XXXX is the serial number of your
DuraNET 20-11.
Username: admin
Password:
SWITCH-XXXX#
At this point the admin user is operating at the highest privilege level, level 15. This means the admin has
full control over the switch and its configuration.
