Basic LS2020 Configuration Tasks
When the system verifies itself as being responsive (through the return of an appropriate
prompt), you can then make the terminal fully operational in your LS2020 environment by
connecting itto theNP. Todoso, proceed directlyto thesection below entitled“Connecting
the Terminal to the NP.”
However, if the system does not respond at all, or if screen output is garbled after you press
the Return key, one of the following conditions may pertain:
• An apparent mismatch of the terminal and the console port baud rates exists. Such a
mismatch may occur, for example, if the console port has been initialized previously
with a baud rate different from that of the terminal.
In this case, you must attempt to achieve a baud rate match by continuing with Step 4
below.
• A connection may exist to a non-operational card or a card that has been physically
removed from the system, but to which a logical connection still exists.
In this case, proceed with Step 3 below.
Step 3 Issue the character sequence ‘. (back quote plus dot, that is, left single quote plus period)
at theterminal keyboard andpress the Return key.This actionbreaks theconnection which
may exist between the switch card and any non-operational or missing card.
If a valid system prompt does not appear following Return key activation, a baud rate
mismatch still exists and you must continue with Step 4.
Step 4 For baud rate matching purposes, your LS2020 chassis must be equipped with at least one
switch card and a terminal.
Set the terminal to a new baud rate, using the order of precedence defined for the console
port in the section above entitled “Setting Console/Modem Baud Rates through TCS Hub
Commands.”
Step 5 Press the Return key on the terminal.
Step 6 If the baud rates match after you press the Return key, the TCS hub prompt is displayed,
indicating that the terminal is properly attached.
Proceed to the section below entitled “Connecting the Terminal to the NP.”
However, if the TCS hub prompt is not displayed, you must repeat Step 4 and Step 5 until
a match with one of the defined baud rates is achieved.
If the terminal does NOT support one of the defined console port baud rates, proceed with
Step 7 below.
If you cycle through all the possible console baud rates withoutachieving a match, an error
condition exists. In this case, contact your Cisco Systems customer support representative.
Step 7 For baud rate selection, this step requires that your LS2020 be equipped with a modem
attached to the same switch as the terminal and that you have the ability to dial into the
LS2020 chassis.
If you can dial into the LS2020 chassis, do so. Then continue with Step 8 below.
If you are unable to dial into the chassis, skip to Step 10 below.
Step 8 Use the TCS hub set <switch slot> console baudrate <rate> command to set the
baud rate of the console port to agree with that of the terminal you are attempting to attach.
Step 9 Reset the applicable switch card.
This action reinitializes the console port to the baud rate selected in Step 8 above.
