INSTALLATION
The P840 is an ISDN Ethernet Bridge/Router that provides bridging,
IP/IPX routing, and compression over a PPP ISDN connection and
support an ISDN BRI interface via an integral ISDN-ST or ISDN-U link
module. The ISDN BRI interface supports two 64 Kbps B-channels.
Two analog telephone connections are also available when the voice port
module is included on a unit with voice support.
The following instructions provide a quick set-up guide for installation of
the P840 Router:
Unpack the P840 Router
Rough handling during shipment can damage electronic equipment. As
you unpack the bridge/router, carefully check for signs of damage. If
damage is suspected, contact the shipper. Save the box and all packing
material to protect the bridge/router should it ever need to be moved or
returned for service.
Check the packing slip that identifies the components and the LAN
connector. The connectors on the rear of the bridge/router provide all
external connections to the P840 Router.
Select a Site
Place the bridge/router in a well-ventilated area. The site should
maintain normal office temperature and humidity levels. Air vents
located on the rear of the bridge/router must have an inch or so of
clearance from any object.

SECTION 2
TYPICAL APPLICATIONS & HOW TO
CONFIGURE THEM
The P840 is a flexible Ethernet Bridge/Router that supports PPP ISDN
circuits. This section will describe how to set up the P840 networking
functions.
The P840 may be configured as a simple Ethernet bridge, an Ethernet IP
router, an Ethernet IPX router, or a combination of the three. When
operating the P840 as a combination bridge/router simply configure each
of the components separately.
Note: The configuration options described within this section are only for initial set
up and configuration purposes. For more complete information on all of the
configuration parameters available, please refer to the P840 PPP Menus
Reference Manual PDF file on the accompanying CD-ROM
Important: The P840 uses FLASH memory to store the configuration
information. Configuration settings are stored to FLASH memory
after there has been 30 seconds of idle time. Idle time is when there
is no selection or modification of the value in the built-in menu
system. If you wish to store a configuration immediately, enter “=”
to jump to the main menu, then select option “6” to save the
configuration.

Applications
13
Managing the P840
Using the Menus
This section describes the minimum configuration parameters required
when setting up the P840. Each of the configuration scenarios requires
setting of operational parameters on the P840. The built-in menu system
of the P840 is used to configure the unit.
The Router menu system operates on a “hotkey” principle; navigating
around the menu system is done by typing the number associated with
the desired option; the P840 acts on the choice immediately (no need to
hit the “enter” key).
The menu system consists of different menu levels each containing new
configuration options. Navigation back out of a nested menu is easily
accomplished by pressing the “tab” key. The tab key takes you to the
previous menu level. If you wish to move from your current menu
location directly to the main menu simply press the equals “=” key.
When choosing menu options that will toggle between values, simply
pressing the number associated with that option will cause the options
value to change. Each successive selection of the option will cause the
option’s value to change again.
Some menu options require input from the operator. When selecting an
option that requires a value, the menu system will display the range of
values acceptable and a prompt symbol “>”. Enter the new value at the
prompt symbol and press enter. Should you make an error in entering
the new value, the <BACKSPACE> key (for most terminals) deletes the
most recently entered characters.
