I cant access it by console as well, i am using hyperterminal.

What should i do??

I have resolve the problem

Solution

try this

1. Download the code 9.3R4 from the Juniper site.
2. Copy the code to USB drive (thumb drive) to the root.

Note: Make sure the USB drive supports FAT32, remove the files and folders if you have any and do a quick format to the USB.

3.   Once done remove the USB drive from PC and plug it to the switch at the rear side.

4.   Power on the switch. The loader script starts.

5.   After the Loading /boot/defaults/loader.conf displays, you are prompted with:

Hit [Enter] to boot immediately, or space bar for command prompt.

1. Hit the space bar to enter the manual loader.

The loader> prompt displays.
(NOTE: There is a 1 second delay for hitting the space bar)

7.   Enter the following command:
loader>    install file:///jinstall-ex-9.3R4.4-domestic.tgz

Note: file:///jinstall-ex-9.3R4.4-domestic.tgz is the file name of the code copied to USB drive
      8.   The installation proceeds as normal and ends with a login prompt.

Note: It may take 5 to 10 Minutes

add the --format option to the install command. You may not always need it but for the one time you do, its not that much of a wait.
