Serial Port Connection
Setup
The 2250 switch has a serial port for initial configuration of the IP address.
This port can also be used for service purposes. The serial port should not
be used during normal operation.
Remove the dust cover from the serial port before inserting the serial
Note
cable.
Do not use the serial port during normal operation or for regular
Note
maintenance. Remove the serial port cable and, using the dust cover
supplied with the switch, cover the port during normal operation of the
switch.
To set the IP address on the switch for normal Ethernet access, perform the
following initial procedure:
1. Attach the provided serial cable between the serial port on the switch and
an RS-232 serial port on your laptop or host computer. The cable is wired
with only pins 2, 3, and 5 wired straight through.
If needed, the adapter can be removed to allow for RJ45 serial
Note
connection to your host computer.
2. Turn on the switch and wait for the power on self test (POST) to complete.
POST is complete when all LED activity has stopped; this takes
approximately 2 minutes.
3. Disable all serial communication programs running on your computer,
such as sync programs for a PDA.
4. Run a terminal emulation program such as Hyperterm on Windows
95/NT, or TERM in a Unix environment.
5. Configure the terminal for 9600 Baud, 8 Data Bits, No Parity, 1 Stop Bit,
and no flow control. Click OK.
6. Press
to get a prompt.
Enter
7. If prompted, provide a login and password. The default is login =
