Warning about FLASH memory
Before you start to configure your router, note that it is possible to enter
commands that can impact severely on your router’s performance.
DO NOT clear the FLASH memory completely. The software release files are
stored in FLASH, and clearing FLASH memory would leave no software to run
the router.
While FLASH is compacting, do not restart the router or use any commands
that affect the FLASH file subsystem. Do not restart the router, or create, edit,
load, rename or delete any files until a message confirms that FLASH file
compaction is completed. Interrupting flash compaction may result in damage
to files. Damaged files are likely to prevent the router from operating correctly.
For more information, see “How to Avoid Problems” on page 89 and “What to do
if you clear FLASH memory completely” on page 90.
Connecting a Terminal or PC
The first thing to do after physically installing the router is to start a terminal
session to access the router. Then you can use the command line interface (CLI)
to configure the router.
You can use a PC running terminal emulation software as the manager console
instead of a terminal. Many terminal emulation applications are available for
the PC, but the most readily available are the HyperTerminal application
included in Microsoft® Windows™ 95, Windows™ 98, and Windows™ 2000.
In a normal Windows™ installation HyperTerminal is located in the
Accessories group. In Windows™ 2000, HyperTerminal is located in the Start >
Programs > Accessories > Communications menu.
The key to successfully using terminal emulation software with the router is to
configure the communications parameters in the terminal emulation software
to match the default settings of the console port on the router. For instructions
on how to configure HyperTerminal, see the AR Series Router Hardware
Reference.
To start a terminal session, connect to the router in one of the following ways:
■
Connect a VT100-compatible terminal to the RS-232 Terminal Port, set the
communications parameters on the terminal (Table 1 on page 15), and
press [Enter] a few times until the router’s login prompt appears; OR
■
Connect the COM port of a PC running terminal emulation software such
as Windows Terminal or HyperTerminal to the RS-232 Terminal Port, set
the communications parameters on the terminal emulation software
(Table 1 on page 15), and press [Enter] a few times until the router’s login
prompt appears.
