Downloading a New Image
The image file contains the executable code that runs on the switch and is preinstalled at the factory. As
new versions of the image are released, you should upgrade the software running on your system.
ExtremeWare XOS 11.1 introduces support for hitless upgrade on the BlackDiamond 10K switch. See
“Understanding Hitless Upgrade—BlackDiamond 10K Switch Only” on page 423 for more information.
The image is upgraded by using a download procedure from a Trivial File Transfer Protocol (TFTP)
server on the network or an external compact flash memory card installed in the external compact flash
slot of the Management Switch Fabric Module (MSM). Downloading a new image involves the
following steps:
●
Loading the new image onto a TFTP server on your network (if you will be using TFTP).
●
Loading the new image onto an external compact flash memory card (if you will be using the
external compact flash slot). Use a PC with appropriate hardware such as a compact flash reader/
writer and follow the manufacturer’s instructions to access the compact flash card and place the
image onto the card.
For more information about installing the external compact flash memory card into the external
compact flash slot of the MSM, please refer to the
Extreme Networks Consolidated XOS Hardware
Installation Guide .
●
Selecting the partition to use when downloading an image. For more information, see “Selecting a
Primary or a Secondary Image” on page 421 .
●
Downloading the new image to the switch using the following command:
download image [[<hostname> | <ipaddress>] <filename> {{vr} <vrname>} | memorycard
<filename>] {<partition>} {msm <slotid>}
Before the download begins, the system asks if you want to install the image immediately after the
download is finished. If you install the image to the active partition, you must reboot the switch. If
you install the image to the inactive partition, you do not need to reboot the switch. Enter
y
to install
the image after download. Enter
n
to install the image at a later time.
