Cisco Catalyst X4232 Installation And Configuration Note page 31

If all the interfaces are down or no IP address has been assigned to any interface or subinterface that is
up, the IP address for network management is 0.0.0.0.
After each IP address selection or change of the IP address, the Layer 3 Services module sends an
unsolicited message to the supervisor engine, which then populates the IP address attribute of the Cisco
Stack MIB entry of the Catalyst 4000 Layer 3 Services module.
Recovering an Image Using Xmodem or Ymodem
Use Xmodem to download a system image to the Catalyst 4000 Layer 3 Services module
Caution
only if all local images are damaged or erased. Xmodem will download and boot the
downloaded system image. After the Catalyst 4000 Layer 3 Services module is up and
running again, make sure that you download a valid image to bootflash before you reload
the module.
You can download an image from a local or remote computer (such as a PC, UNIX workstation, or
Macintosh) through the console port using the Xmodem or Ymodem protocol. Xmodem and Ymodem
are common protocols used to transfer files and are included in applications such as Windows 3.1
(TERMINAL.EXE), Windows 95 (HyperTerminal), Windows NT 3.5x (TERMINAL.EXE),
Windows NT 4.0 (HyperTerminal), and Linux UNIX freeware (minicom).
Xmodem and Ymodem downloads are slow. You can speed up the transfer by setting the console port
speed to 57600 bps.
Perform Xmodem file transfers from the ROM monitor with the following command:
xmodem [-cys] [-c
where speed may be 1200|2400|4800|9600|19200|38400|57600]
The computer from which you transfer the supervisor engine software image must be running terminal
emulation software that supports the Xmodem protocol.
Caution A modem connection from the telephone network to your console port introduces security
issues that you should consider before enabling the connection. For example, remote users
can dial in to your modem and access configuration settings.
To transfer a file using Xmodem or Ymodem protocol, perform these steps:
Note You must establish network connectivity to the module to copy an image file from a TFTP
server to the flash devices.
Step 1 Place a Catalyst 4000 Layer 3 Services module software image on the computer's hard drive. You can
download an image from Cisco.com. See "Cisco.com" section on page 79.
On Windows 95 or 98, configure a HyperTerminal connection directly to COM1 with the following
Step 2
settings: 9600 baud, 8 data bits, no parity, 1 stop bit, flow control Xon-Xoff.
Use a cross-over cable to connect from COM1 to the AUX port on the Catalyst 4000 Layer 3 Services
Step 3
module. Use a DB-9 connector at the PC to connect to a female RJ-45, then cross over the RF-45 to the
Catalyst 4000 Layer 3 Services module.
Boot the Catalyst 4000 Layer 3 Services module to the ROMMON prompt.
