Netgear GSM7248 Switch Initial Setup
Hello everyone!
This is driving me crazy. I've never set this up before, so I am completely lost.
I bought a 48 port switch off of eBay that only had minor damage to the exterior, but was promised fully working. I got it to replace my 2 24 port 10/100 switches that I have now.
What I'm trying to do is simply assign an IP address to the switch so I can go in and manage it, but I can't seem to figure out how to do this.
From what I have read, I have a serial cable hooked up and I am running Dave's Telnet to emulate a VT100 Terminal, but I can't get a login. This is where I get lost. To connect, it asks me for a host name, which I think is supposed to be the IP Address, but I don't have the IP Address, because that's what I'm trying to get to in the first place! Aggghhh!
I have also tried PuTTY, which seems to get almost connected (I think). I choose the COM port and it comes up with a green screen cursor, but I hit enter and I can never get to a login screen.
What do I need to do to communicate with this properly?

I did what you suggested kittuskattus; I cannot find an IP address that was added...
I checked twice on the DHCP lease list. I also ran FastResolver and cannot find any IP address assigned with the MAC Address of the switch.

Have you tried making an address reservation on the DHCP server for the MAC address of the switch? (assuming that the MAC is printed on a sticker somewhere!)
Just thought - some of the Netgear switches have 2 reset buttons - once you can press with your finger and one that is recessed and you need a paperclip to press. It's the recessed one that does the factory reset.

How do I make the address reservation? I have a Linksys EA2700 router that I am using.
Also, the reset is in the front and it is recessed. I used a small screwdriver to reset it.

You can usually tell if the reset has worked by watching the LEDs - they will all change whilst you are holding the button down. Maybe if it doesn't do it after 2 secs, hold it a bit longer!
I don't have access to one right now to check but i think it's in Settings/Basic Settings/DHCP Reservations/Add Client

I found where to put the DHCP reservation.
I put in the MAC address and assigned it 192.168.0.201. I gave it the client name GSM7248, because I have no idea what it is supposed to be.
I appreciate you working with me on this. I am heading home at the moment, but it is still not communicating. I have this computer going through the switch and I'm getting an IP address VIA DHCP just fine...
I tried to connect to 192.168.0.201 and get nothing.
I tried to ping 192.168.0.201 and I get the response "Reply from 192.168.0.110: Destination Host Unreachable"

I guess that's why I was hoping to try to go through the serial connection, because from my understanding that's where I can manually change the IP address for the switch.
Rather than using Putty have you tried using TeraTerm? It was the only program that I could get to set an IP address through the serial port on an APC UPS Network Management Card.

As it's an eBay special I'm assuming that the switch is a GSM7248v1.
The manual can be found here:
http://www.downloads.netgear.com/files/gsm7212_gsm7224_gsm7248_60015_installguide.pdf
... and explains how to to do the initial configuration. I think PuTTY will be very useful!
Netgear's site also has documentation for the GSM7248v2 model.

Perarduaadastra;
Yes it is a v1 of the switch. The problem I'm having is trying to communicate using PuTTY. I've never used it before so this is very unfamiliar to me. I have downloaded the manual, but following the instructions (as far as I read), I still can't get it to communicate.

I have access to a GSM 7224v1 which is probably a very early model; I don't remember the gruesome details of setting it up as it was the best part of two years ago, but I do remember what a mission it was to update the factory release firmware to something a bit more current... Oddly enough, I don't remember console access as being a problem. I'll try and get to it later this evening and hopefully let you know how it's done.

That would be awesome! Thank you Perarduaadastra!

Oh my gosh! You won't believe this!
I set the baud rate to 9600 as suggested by Perarduaadastra and it finally came up with asking for user!
However, now I have a secondary problem. According to the manual I downloaded (BTW, if I didn't answer this before, it is a V1), the default User is admin and default password is none. But, I can't seem to log in. I have pressed the reset in the front multiple times, holding it down for 10 seconds, letting go, then having it blink showing it's resetting.
Any suggestions?

That's odd... A blank password is difficult to enter wrongly!
Have you tried the other usual password suspects? admin, password, 1234, netgear etc... Have you tried upper and lower case for admin?
Are you sure that all the other settings for the serial connection are correct? Serial links are quite fussy about their parameters and tend not to work well or indeed at all unless everything is spot on.
When you are able to log in and are invited to set the password, its maximum length is eight characters; the unit will appear to accept a longer password, but silently truncates anything over that length. I came across this nugget recently when I was looking for something else.

Well, I have to say that I didn't know that either! I'd be inclined to say that I merit only half the points as I provided only half the answer, but I'm not sure if the points award system is that flexible.
That piece of information seems to me to be a worthy addition to the EE database, as it's a technique that might apply to other hardware too.

The complete answer is in the solution I provided, but I came to this conclusion due to the comments marked.
Do a factory reset by pressing the reset switch for 2 secs.
This should set it to DHCP assigned address
Plug it into your network (that has a DHCP server)
Login to the switch webconsole using the IP address it has been assigned.
You can find its IP address in the DHCP server's address leases list, or you could do a IP scan on your subnet using Angry IP scanner (or Fing on a Android/IOS device).
