Symptoms:
The switch is able to get to the point where you can select between the two startup modes. However, the boot up process stops when it attempts to start the switch application.
Error message displayed can vary.
This article does not apply if any of the following is true:
- The switch does not power on.
- No messages are displayed on the console.
- The switch will not boot to the point where startup mode can be selected.
To troubleshoot bootup issues:
Reload the software using the console port:
- Power off the switch.
- Connect a computer to the console port of the switch. If the computer has a serial port, you can use the console cable shipped with the switch by connecting one end of the console cable to the switch’s console port and the other end of the console cable to the serial port of the switch. If the computer does not have a serial port, you will need a USB-to-Serial adapter. Connect the USB connector of the USB-to-Serial adapter to the computer’s USB port, then connect one end of the console cable to the serial connector of the USB-to-Serial adapter and the other end of the console cable to the console port of the switch.
- The computer needs to have a terminal software such as Microsoft Window Hyper Terminal installed. If your system does not have a terminal software, you will need to install a 3rd party terminal software such as Tera Term. You can download Tera Term from http://hp.vector.co.jp/authors/VA002416/teraterm.html. Please note that NETGEAR has no affiliation with Tera Term and does not provide support on using Tera Term.
- Start the terminal software with the settings: baud rate-9600 bps, data bit-8, parity-none, stop bit-1, flow control-none . The firmware image to be loaded onto the switch should be stored on that computer. It is the same firmware image file being used in firmware upgrade.
- Power the switch on. When the console message display the two menu options (1. Start Application. 2. Display Utility Menu), enter “2” to start the Utility Menu.
- Increase the speed of the switch’s console connection. This reduces the time it takes to load software using the switch’s console port.
- After the speed of the console port has been changed, the terminal software has to be reconfigured with the increased speed.
- From the utility menu, select the option to load software using XMODEM.
- From the terminal software, start to transfer the firmware image file using XMODEM. If using Microsoft Hyper Terminal, go to menu Transfer->Send File, browse to the location where the firmware image file is saved and select XMODEM as the protocol, then click the Send button.
- The firmware image will start the transfer to the switch. It will take from 30 minutes to more than an hour for the file to be completely transmitted depending on the console port speed. DO NOT power cycle the switch or interrupt the download from this point on until the download is completed.
- After the file transfer is complete, the switch will start extracting various components into the FLASH. You can see the status in the console messages. After the download process is complete, you will be returned to the Utility Menu. Enter “1” to start application. The switch will boot up fully to the user name prompt.
The switch should now boot up normally.
