Upgrading the BayStack 450 Firmware

The BayStack 450 firmware provides a code load facility that allows you to upgrade the software image over any switch port, including any MDA ports.

The BayStack 400-ST1 Cascade Module will not operate with BayStack 450 switches that are configured with BayStack 450 software versions earlier than version V1.1.0. You must upgrade all units with BayStack 450 software version V1.1.0 (or later) before installing the BayStack 400-ST1 Cascade Modules.

To access the software images, see “Accessing the Software Images” on page 5.
