Obtaining the Rescue Image from a TFTP Server
To recover the switch, you must enter the Bootloader and issue a series of commands. To
access the Bootloader:
1. Attach a serial cable to the console port of the MSM.
2. Attach the other end of the serial cable to a properly configured terminal or terminal
emulator. The terminal settings are:
9600 baud
8 data bits
1 stop bit
no parity
XON/OFF flow control enabled
3. Reboot the MSM and press the spacebar key on the keyboard of the terminal during the
boot up process.
Note: You must press the spacebar key immediately after a power cycle of the
MSM in order to get into the Bootloader application.
On NETGEAR 8800 series switches, when you see the BootRom banner,
press the spacebar key to get into the Bootloader application.
As soon as you see the BootRom -> prompt, release the spacebar. From here, you can
begin the recovery process.
To obtain the rescue image and recover the switch:
1. Provide the network information (IP address, netmask, and gateway) for the switch
using the following command:
configip ipaddress <ip-address>[/<netmask>] gateway <gateway-address>
Where the following is true:
ip-address—Specifies the IP address of the switch
netmask—Specifies the netmask of the switch
gateway-address—Specifies the gateway of the switch
2. Download the XCM8800 image using the following command:
download image <tftp-address> <filename>
Where the following is true:
tftp-address—Specifies the IP address of the TFTP server that contains the
XCM8800 image
filename—Specifies the filename of the XCM8800 image
If you attempt to download a non-rescue image, the switch displays an error message
and returns you to the
BootRom -> command prompt.
