Hello,

do you remember to save the running-config as the startup-config? Also check if you are running the latest firmware, since there have been some changes regarding PoE.

I have a problem with the ISW switches .When I configure an uplink port (port 1/8) in switchport mode trunk.I perform a backup with the command copy running startup. Then i perform a cold reboot .After the cold reboot , the uplink port is in access mode and the switchport mode trunk has disappeared from my configuration.I have installed the latest software V01.01.06.0001.dat

It's a software bug in version V01.01.06.0001.dat. I have downgrade the switch in version V01.01.05.0004.dat and the problem has disappeared.
