Need help with used Bay Networks (Nortel) 24 port switch

I bought a 24 port switch at my local used computer parts store, and did not realize what I had gotten myself into until I got it home. I need to start off with a full reset, but being a high end switch (for its day), I cannot figure out how to do it. I have been to the manufacturers website, searched the web for hours, and my personal e-book library and cannot come up with anything resembling a starting point.

I have a good amount of experience with garden-variety home network hubs and networking, but not with these switches. I have a console cable that was left over from a previous job, but I have never used it. Nor do I really know how to use it. They just told me I had to have one. I understand that I may be in a little over my head here, but this is a "skill" I need to have. If I can get pointed into the right direction, I bet I can figure the rest out or research it.

My real questions are:

1) What is the difference between console and telnet. I think I know, but I could use some help. Which is easier, and how do I connect?

2) How can I do a full reset on the switch, back to factory default (if it isn't already)?

The switch is a Bay Networks (apparently bought out by Nortel).
BayStack 450-24T Switch
Model# AL2012A14
Part# 300798-A REV 17
Serial# KEC01034234
MAC# 0060FDA74BE9
In the end, it will be on a domain environment running active directory.

I hope I included enough info, and thanks for any help

A switch is not designed to work alone. Did you connect it behind a router? A switch will not assign IP addresses where a router will. You need this for everything else to work.

Yes, I know this much

I know that it needs a form of DHCP server or some such function to work, but I cannot get it to connect because (I think) the IP range set in the switch is different from what I am running. Is there a way to get into it and change that, or if I put it behind my current router/modem I will have better luck?

If I simply connect it to my laptop, with no other network connections, it will (as I expected) go to "limited or no connectivity" status. The IP I get is and a subnet of and nothing listed for the default gateway. On my local network, the internal IP addresses are 168.153.*.*, so how do I get connected to the switch in such a way that I can fiddle with settings?

169 is a known thing.

In reply to: Yes, I know this much

This is not a router or much else. The 169 range is correct. Now go get a router and connect it like this:

internet -> Router -> Your switch.

Have you looked at the Nortel network site

for any discovery or management software? The only reason you'd need to get into the web interface is for management purposes. Of course you'd need the IP address. If you know or can discover that, you might be able to use a web browser and just http://(IP address) to get to the interface. Your next dilemma will probably be the admin password. If that's been set, you may be dead in the water. Whether or not you can just use the switch as is depends on what someone may have done with the individual ports. They could have been disabled, locked to a MAC address, limited in connection speed, or any of a number of things an administrator might to to control traffic. Have you tried just connecting a few devices to it to see if they connect to your network? If it won't work as a stand alone switch, I'd think it's either defective or it's been altered by someone.
