Connecting the Console Port (RS-232 DCE)
The Switch provides an RS-232 serial port that enables a connection to a computer or terminal for monitoring and configuring the
Switch. This port is a female DB-9 connector, implemented as a data terminal equipment (DTE) connection.
To use the console port, the following equipment is needed:
•
A terminal or a computer with both a serial port and the ability to emulate a terminal.
•
A null modem or crossover RS-232 cable with a female DB-9 connector for the console port on the Switch.
To connect a terminal to the console port:
Connect the female connector of the RS-232 cable directly to the console port on the Switch, and tighten the captive retaining
screws.
Connect the other end of the cable to a terminal or to the serial connector of a computer running terminal emulation software. Set
the terminal emulation software as follows:
•
Select the appropriate serial port (
COM port 1
or
COM port 2
).
•
Set the data rate to
115200 baud
.
•
Set the data format to
8 data bits
,
1 stop bit
, and
no parity
.
•
Set
flow control
to
none
.
•
Under Properties, select
VT100
for Emulation mode.
•
Select
Terminal
keys for
Function
,
Arrow
and
Ctrl
keys. Make sure to use Terminal keys (not Windows keys) are selected.
NOTE:
When using HyperTerminal with the Microsoft® Windows® 2000 operating system, ensure
that Windows 2000 Service Pack 2 or later is installed. Windows 2000 Service Pack 2 allows use
of arrow keys in HyperTerminal's VT100 emulation. See www.microsoft.com for information on
Windows 2000 service packs.
•
After you have correctly set up the terminal, plug the power cable into the power receptacle on the back of the Switch. The
boot sequence appears in the terminal.
•
After the boot sequence completes, the console login screen displays.
•
If the user has not logged into the command line interface (CLI) program, press the Enter key at the User name and password
prompts. There is no default user name and password for the Switch. The administrator must first create user names and
passwords. If user accounts have been previously set up, log in and continue to configure the Switch.
•
Enter the commands to complete desired tasks. Many commands require administrator-level access privileges. Read the next
section for more information on setting up user accounts. See the
xStack
®
DGS-3400 series CLI Manual
on the
documentation CD for a list of all commands and additional information on using the CLI.
•
To end a management session, use the logout command or close the emulator program.
If problems occur in making this connection on a PC, make sure the emulation is set to VT-100. The emulation settings can be
configured by clicking on the
File
menu in the HyperTerminal window by clicking on
Properties
in the drop-down menu, and
then clicking the
Settings
tab. This is where you will find the
Emulation
options. If you still do not see anything, try rebooting
the Switch by disconnecting its power supply.
