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 Upgrade Process

Upgrading the BayStack 450 switch to software version V4.0.0 is a two-step process:

Download the boot code image.

Download the agent image.

To properly upgrade the BayStack 450 switch, the boot code image

downloaded first

, before you download the agent image. If the agent image (the operational software) is downloaded before the boot code image, the software may not be programmed into the BayStack 450 switch FLASH memory.

The switch indicat es a f ail ed im age lo ad a s foll o w s: An al te rnati ng LED patt ern i s displayed on the BayStack 450-24T 10/100 status LEDs (ports 13 to 24), on the BayStack 450-12T 10/100 status LEDs (ports 1 to 12), and on the BayStack 450-12F Link status LEDs (ports 1 to 12).

If this happ ens, cycle the s witch power (power off the switch, then power it on). Use the Software Download screen to download the new boot code image. After the boot co de image download completes, download the new agent image.

Upgrading to Software Version V4.0.0 in a Mixed Stack

When you upgrade a mixed stack1 to software version V4.0.0, you must first upgrade the agent code, before you upgrade the boot block. Although this is the inverse of the normal upgrade procedure, it is necessary to ensure a successful software upgrade.

The switch will not automatically reset. To recover from this condition, you must cycle power to the switch, upgrade the boot software, and then upgrade the agent software.
