through a procedure called auto-negotiation. Auto-negotiation involves probing the capability of the network using low-level signaling techniques to select compatible Ethernet speeds. Auto-negotiation was originally developed to make the migration from traditional Ethernet to Fast Ethernet products easier. Redundant images in firmware The switch stores up to two different software images, called image1 and image2, as well as boot software, called boot. When downloading new software, the ability to specify where it is to be placed (into image1, image2, or boot) is activated. For example, if the active image is currently loaded into image1, load the new image software into image2. This allows a test of the new software and the option to revert back to the original image stored in image1, if needed. CAUTION: Unlike the firmware that has two images, there is only one image of boot supported. Upgrading the boot image replaces the original boot image.

network using low-level signaling techniques to select compatible Ethernet speeds. Auto-negotiation was
originally developed to make the migration from traditional Ethernet to Fast Ethernet products easier.
Redundant images in firmware
The switch stores up to two different software images, called image1 and image2, as well as boot
software, called boot. When downloading new software, the ability to specify where it is to be placed
(into image1, image2, or boot) is activated.
For example, if the active image is currently loaded into image1, load the new image software into
image2. This allows a test of the new software and the option to revert back to the original image stored
in image1, if needed.
CAUTION:
Unlike the firmware that has two images, there is only one image of boot supported.
Upgrading the boot image replaces the original boot image.
