Since different Flash disks have different sizes, it’s a good idea to check the size of your Flash

disk before upgrading the firmware, or before using the disk to store your application and data

files. Use the

#df –h

command to list the size of each memory block and how much free space is

available in each block.

1. Type the following commands to enable the RAM disk:

#upramdisk

#cd /mnt/ramdisk

2. Type the following commands to use the IA260/IA261/IA262/EM-2260’s built-in FTP client

to transfer the firmware file (ia260/ia261/ia262/em2260-x.x.x.hfm) from the PC to the

IA260/IA261/IA262/EM-2260:

/mnt/ramdisk> ftp <destination PC’s IP>

ftp> bin

ftp> get ia260/ia261/ia262/em2260-x.x.x.hfm
