5 minute delay to start booting of 'extreme 450e 48p' switch

by hmrpanchal / November 19, 2013 2:09 PM PST


We have a 'extreme 450e 48p' switch installed in our organization along with other networking equipments. When power is restrored 'extreme 450e 48p' switch reboot successfully before other networking equipment thereby create some problems, which we don't know why.

So, for a solution we restart this particular switch again by turning power off and then on for this particular switch after successful restart of all other networking equipments.

As per my understanding 5 minute delay to start booting of 'extreme 450e 48p' switch can resolve the issue, if it's so, please let me know how to create a delay or auto reboot once again this switch.

Any other solutions are most welcome.

Clarification Request
If this switch is defective, why keep it?

While there are such things that will delay after a power outage this issue sounds like something else is broken or badly configured.

Here's a power on delay box.
Notice "Extended Cold Start" at

This is just one of dozens of such boxes.

As per me switch is not defective, because when we restart it manually after successful reboot of other network equipments it works fine.

I hope while rebooting this switch search other devices for some configurations/vlan/routes etc

So the issue is with the other gear/systems?

I dealt with this a few times where a hard headed IT staffer was digging in their heels that power must come on in a specific order and time. It was just another day as we worked out what was going on with a server that was getting some information, failing and well, long story short it was another configuration issue.

Yes, we could have used a power delay box but why? Just edit the configuration so it works.

It was the order of services that needed adjusting. Sadly your better IT staffers can deal with it but as I'm not there I can't fix it since it is usually something different each time.

For now, you have found a time delay box so maybe that's your solution. I don't want to upset anyone but it would not be one we would use at our office. But you may want to know our office is mostly programmers and gurus.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
