Updating the Switch Software Image
The switch software image is the executable code running on the switch. A version of the image
ships with the switch, and comes pre-installed on the device. As new versions of the image are
released, you can upgrade the software running on your switch. To get the latest version of
software available for your G8000, go to:
http://www.bladenetwork.net/support_services_rackswitch.html
Click on software updates. Use the /boot/cur command to determine the current
software version.
The typical upgrade process for the software image consists of the following steps:
 Load the new boot image and software image onto a TFTP server on your network.
 Transfer the new boot image and software image from the TFTP server to your switch.
 Select the new software image to be loaded into switch memory the next time the switch is
reset.
Loading New Software to Your Switch
The switch can store up to two different software images, called image1 and image2, as
well as boot software, called boot. When you load new software, you must specify where it
should be placed: either into image1, image2, or boot.
For example, if your active image is currently loaded into image1, you would probably load
the new image software into image2. This lets you test the new software and reload the origi-
nal active image (stored in image1), if needed.
Using the BLADE OS CLI
To load a new software image to your switch, you need the following:
 The image or boot software loaded on a TFTP server on your network
 The hostname or IP address of the TFTP server
 The name of the new software image or boot file
NOTE – The DNS parameters must be configured if specifying hostnames. See “Domain Name
System Configuration” on page 184.
When the above requirements are met, use the following procedure to download the new soft-
ware to your switch.
