Configuring PowerConnect 3524/P and 3548/P 63
Software Download Through TFTP Server
This section contains instructions for downloading device software (system and boot images) through a
TFTP server. The TFTP server must be configured before downloading the software.
System Image Download
The device boots and runs when decompressing the system image from the flash memory area where a
copy of the system image is stored. When a new image is downloaded, it is saved in the other area
allocated for the other system image copy.
On the next boot, the device will decompress and run from the currently active system image unless
chosen otherwise.
To download a system image through the TFTP server:
1
Ensure that an IP address is configured on one of the device ports and pings can be sent to a TFTP
server.
2
Make sure that the file to be downloaded is saved on the TFTP server (the
arc
file).
