If the default settings for the management agent’s serial port have been modified
and you are having difficulty making a console connection, you can display or
modify the current settings using a Web browser as described under “Configuring
the Serial Port” on chapter 3.
1.2.2.Remote Management Via the Console Port 1.2.2.1.Configuring the Switch Site
Connect the switch’s DB9 serial port to the modem’s serial port uses standard cabling.
For most modems which use a 25-pin port, you will have to provide an RS-232 cable
with a 9-pin connector on one end and a 25-pin connector on the other end. Set the
modem at the switch’s site to force auto-answer mode. The following is a sample
initialization string: “ATQ1S0=1&D0&K0&W” as defined below:
Q1 : Inhibit result codes to DTE
S0=1 : Auto answer on first ring
D0 : Don’t care DTR
K0 : Disables DTE / DCE flow control
W : Write command to modem memory
1.2.2.2.Configuring the Remote Site
At the remote site, connect the PC’s COM port (COM 1~4) to the modem’s serial port.
Set terminal emulation type to VT100, specify the port used by your PC (i.e., COM 1~4),
and then set communications to 8 data bits, 1 stop bit, no parity, 19200 bps, and no flow
control.
1.2.3.In-Band Connections Prior to accessing the switch’s onboard agent via a network connection, you must first
configure it with a valid IP address, subnet mask, and default gateway (for Layer 2
mode) using an out-of-band connection or the BOOTP protocol.
After configuring the switch’s IP parameters, you can access the onboard configuration
program from anywhere within the attached network. The onboard configuration
program can be accessed using Telnet from any computer attached to the network. The
switch can also be managed by any computer using a Web browser (Internet Explorer
4.0 or above, or Netscape Navigator 4.0 or above), or from a network computer using
network management software.
Notes:
1. By default BOOTP is disabled. To enable BOOTP, see “IP Configuration
(Layer 2 Mode)” on chapter 2.
