c3750e Stack IOS upgrade process

The Software Advisor was unable to help me locate the newest version of this image I currently run in my stack of four 3750e switches:

4x WS-C3750E-48TD 12.2(44)SE C3750E-UNIVERSALK9-M

Image File: c3750e-universalk9-mz.122-44.SE

1. Is there a newer 12.3.x or 12.4.x image that is compatible with this one?

2. I understand that the master switch will automatically upgrade the IOS in the other switches in the stack; can someone link the upgrade documentation to me, so I can read up before trying this?

Thanks,

Marc

You are running one of the newest images out there for that switch . There is no 12.3 or 4 image for the 3750. Upgrade info

Thanks for the speedy reply;

I asked because we've been experiencing spontaneous switch crashes that move the master to another switch in the stack; later on, when the crash repeats, the master moves back up:

%PLATFORM-1-CRASHED: (various output text)

My original concern was a bad image; should I reinstall IOS, or is there something specif to look for here?

Marc,

Here's a link to the upgrade procedure for 3750's in a stack.

As far as the latest image I believe 12.2.44-SE2(ED) is the latest one, but you can check at cisco's software download site.
