Upgrade Restrictions
The following restrictions apply when you upgrade the switch to
software version V4.0.0:
• When you upgrade a stack configuration (running software versions earlier
than V2.0) that uses a Gigabit distributed trunk for the uplink to the TFTP
server, you must first disable the MultiLink Trunk at both ends.
• When you upgrade a stack configuration that contains a BayStack 410-24T
unit (which is configured with at least one distributed trunk member), and the
distributed trunk is the uplink to the TFTP server, you must first disable the
MultiLink Trunk at both ends.
Note:
When upgrading the switch, you must download
two images
, the
boot
code image
(the firmware) and the
agent image
(the software).
