450 Baystack stack, multiple 450-1sx MDA

[JonesDave]

Pardon my ignorance; but I have little experience with Nortel equipment.

We have an existing network, where the closets contain Baystack 450-24 switches (typically 4 to a stack) with single 450-1SX MDA's and the 45-FX dual port in some. A second "recovery" server room was installed with fiber to all closests. The stacks with dual 450-FX MDA's were fine with the second connection.

We have 5 closets with 1 gB connection with single port 450-1SX MDA's. When the 2nd 450-1SX MDA is placed in a stack and its powered up; the stack does not come up right and the 2nd switch with the new 450-1SX does not work. Take it out; power back up and its working as before.

Vendor has tried this on two different closets with same results.

Is it possible to have multiple 45-1SX MDA's in a stack or is the vendor trying to do something that is not supported?

What version of code is on the 450's? I don't recall that being an issue, but I could check. I've got multiple 450-1SX MDAs in a hybrid BPS 2000/460/450 stack with no issues. But, my MDAs are in a BPS and 460 respectively, not a 450.

The stacks have HW:RevL FW:V1.44 SW:v2.0.0.28 (hope thats what you need).

That's old. Really old.

I'd recommend updating the code on the switches. Here's a link to a site that posts the software for the 450 switches.
