Overview
For easy software image management, all devices support the download and upload of software
images between the flash modules on the devices and a Trivial File Transfer Protocol (TFTP) server
on the network.
PowerConnect devices have two flash memory modules:
• Primary flash – The default local storage device for image files and configuration files.
• Secondary flash – A second flash storage device. You can use the secondary flash to store
redundant images for additional reload reliability or to preserve one software image while
testing another one.
Only one flash device is active at a time. By default, the primary image will become active upon
reload.
You can update the software contained on a flash module using TFTP to copy the update image
from a TFTP server onto the flash module. In addition, you can copy software images and
configuration files from a flash module to a TFTP server.
NOTE
PowerConnect devices are TFTP clients but not TFTP servers. You must perform the TFTP
transaction from the device. You cannot “put” a file onto the device using the interface of your TFTP
server.
NOTE
If you are attempting to transfer a file using TFTP but have received an error message, refer to
“Diagnostic error codes and remedies for TFTP transfers” on page 51.
Determining the software versions installed and

Use the following methods to display the software versions running on the device and the versions
installed in flash memory.
Determining the flash image version running on the device
