Cyclades recommends the use of Category 5, shielded twisted-pair cables for Fast Ethernet connections.
The Cyclades-PR1000 comes with rubber pads to prevent it from slipping on a horizontal surface. It may be
necessary to affix the router more securely to either a horizontal or vertical surface. To this end, Velcro® strips
and screws have been provided.
Chapter 2 - What is in the Box 14
Cyclades-PR1000
Horizontal Surfaces
The Velcro® strips should be used to attach the PR1000 more firmly to a horizontal surface. Remove the
backing from the prickly Velcros® and attach them to the router as shown in the figure. Remove the backing
from the fuzzy Velcros® and place them on the horizontal surface so they are aligned with the Velcros® on the
router .

There are two slots in the base of the PR1000 to allow it to be affixed to a vertical surface. Screws and nylon
fixings (for cement walls) are provided for this purpose.
Make holes 184,8mm (7.27 in) apart on the vertical surface. If using a drill, a 5mm bit should be used. Four
millimeters (or a little more than 1/8 in) of the screw should be exposed (not counting the head).

Chapter 3 Using CyROS Menus
This chapter explains CyROS menu navigation and special keys. There are three ways to interact with CyROS:
• Traditional menu interface using a console or Telnet session,
• CyROS Management Utility based on interactive HTML pages,
• SNMP (explained in the CyROS Reference Manual).
Connection Using the Console Cable and a Computer or Terminal
The first step is to connect a computer or terminal to the router using the console cable. If using a computer,
HyperTerminal can be used in the Windows operating system or Kermit in the Unix operating system. The
terminal parameters should be set as follows:
• Serial Speed: 9600 bps
• Data Length: 8 bits
• Parity: None
• Stop Bits: 1 stop bit
• Flow Control: Hardware flow control

FIGURE 3.1 LOGIN PROMPT AND MAIN MENU
Chapter 3 - Using CyROS Menus 19
Cyclades-PR1000
Once the console connection is correctly established, a Cyclades banner and login prompt should appear on the
terminal screen. Pressing <ESC> during the boot process will temporarily halt initialization and present several options:
IP address of the router , IP address of the boot server, boot from network, MAC address, etc. If the login prompt does
not appear, see the first section of the troubleshooting appendix for help. Next, log in. The preset super-user user ID
is “super” and the corresponding preset password is “surt”. The password should be changed as soon as possible, as
described in chapter 10 of the installation manual and at the end of every example in chapter 4. The login prompts and
main menu are shown in Figure 3.1.
All menus have the following elements:
• Title – In the example in Figure 3.1: “Main Menu”.
• Prompt – The text: “Select Option ==>”.
• Options –The menu options, which are selected by number.
• Router Name – The default is the name of the product. Each router can be renamed by the super user for
easier identification.
Menus can also be navigated using a short-cut method. This method must be activated first by choosing a
shortcut character (“+” in the example that follows) in the CONFIG =>SYSTEM =>ROUTER DESCRIPTION
menu. Typing 4+1+1 at the main-menu prompt, for example, is equivalent to choosing option 4 in the main
menu (Debug), then choosing option 1 in the debug menu (Trace), then choosing option 1 in the trace menu
(Driver Trace). In addition to menus, some screens have questions with letter choices. In the line below, several
elements may be identified:
lmi-type((A)NSI, (G)roup of four, (N)one )[A]:
• Parameter description – The name of the parameter to be configured, in this case “lmi-type”.
• Options – Legal choices. The letter in parentheses is the letter that selects the corresponding option.
• Current value – The option in square brackets is the current value.
Pressing <Enter> without typing a new value leaves the item unchanged.

These keys are used to end the input of a value.
These keys are used to cancel a selection or return to the previous menu. In
some isolated cases, this key forwards you to the next menu in a series of
menus at the same level.
>
These keys have the expected effect of erasing previously typed characters.
When availabl e, this option displa ys the curre nt configuration. For example, i n
the Ethernet Interface Menu, “L” displays the Ethernet configurations.
On leaving a menu where a change in configuration was made, CyROS will ask whether or not the change is to
be saved:
(D)iscard, save to (F)lash, or save to (R)un configuration:
Selecting
Discard
will undo all changes made since the last time the question was asked. Saving to
Flash
memory makes all changes permanent. The changes are immediately effective and are saved to the
configuration vector in flash memory. In this case, the configuration is maintained even after a router reboot.
Saving only to the
Run
configuration makes all changes effective immediately, but nothing is saved permanently
until explicitly saved to flash (which can be done with the option ADMIN =>WRITE CONFIGURATION=>TO
FLASH).
The menus and parameter lists are represented in this manual by tables. The first column contains the menu
item or the parameter, and the second column contains its description.
This menu interface is also available via Telnet if one of the interfaces has been connected and configured. The
menu interface is the same as that described earlier in this section. Using Telnet instead of a console for the
initial Ethernet configuration is discussed in Appendix C of the Installation Manual.
Chapter 3 - Using CyROS Menus 21
Cyclades-PR1000
The CyROS Management Utility
After one of the interfaces has been connected and configured, there is another way to interact with CyROS. Type the
IP address in the location field in an HTML browser of a PC connected locally or remotely through the configured
interface. A super-user ID and password will be requested (these are the same ID and password used with the lineterminal interface). A clickable image of the router back panel will apear, as shown in Figure 3.2.

CHAPTER 4 STEP-BY-STEP INSTRUCTIONS FOR COMMON APPLICATIONS
This chapter provides detailed examples that can be used as models for similar applications. Turn to the example
that is closest to your application, read the explanations, and fill in the blank spaces with parameters appropriate
to your system. At the end of the section, you should have listed all the parameters needed to configure the
router . At that point, read chapter 3 if you have not already , and configure your router with help from later chapters
of the Installation Manual, when needed.
Example 1 Connection to an Internet Access Provider via Modem
This section will guide you through a complete router installation for the connection of a LAN to an Internet access
provider via PPP. The configuration of NAT (Network Address Translation) will also be shown. Figure 4.1 shows
the example system used in this section. Note that this example assumes that the IP address to which the
network IP addresses will be translated is assigned dynamically by the Internet Service Provider . For configuration
of a known IP address, see the chapter on NAT configuration in the complete Installation Manual. Spaces have
been provided next to the parameters needed for the configuration where you can fill in the parameters for your
system. Do this now before continuing.

Please read the entire example and follow the instructions before turning the router on. The router is
programmed to log the super user off after 10 minutes of inactivity. All data not explicitly saved to
memory is then lost. Collecting the data
while
configuring the router will likely cause delays and
frustration.
STEP ONE
The first step is to determine the parameters needed to configure the Ethernet interface (ETH0). The parameters
in the Network Protocol Menu (IP) are shown in Figure 4.2. Fill in the blanks for your application in the right-most
column. These parameters will be entered into the router later, after all parameters have been chosen. Each
parameter in this menu is explained in more detail in chapter 5 of the Installation Manual.
