The master switch will syn the config with the secondary switch. So taking the master switch offline, letting the secondary switch become the master, and then attempting connection will be the lowest risk of losing any config changes. With the switches being in production for as long as they have, I would imagine that the running config and startup config are the same. So there is a good chance that upon reboot the only things that may not be saved are the changes you made.
Hi, I was contacted by a company who had lost their entire skillset when an employee left, and powerconnects are not my strongpoint.  THey have 4 stacked 3548P's - console ports are  inactive, and web gui stopped responding. we need to do some config, and I don't understand how to "restart/reset" the network, to get the web gui back. I suspect that a reboot would kick it all back to life, but this is their entire LAN I am juggling with.  How do you reboot a stacked network? is it safe?  Could the loss of web GUI response be attributable to anything else?  All other traffic on the LAN is working correctly.   regards, Andy Taylor
