3Com NBX - Recent Questions, Troubleshooting & Support
Default gateway
Depending on the mode the phone is in, it may be only a layer 2 device - meaning it just broadcasts at layer 2 to find the NBX and once discovered, uses layer 2 for all communication.
A user's phone calls keep dropping out during
I would recommend starting with what is simple.
Have you tried replacing the Ethernet patch cord that the phone is connected to?
How about the curly cord between the phone and handset?
Does the phone do the same thing if you connect it to a different port?
Does a different phone do the same then when connected where this phone is connected?
PEOPLE CANNOT DIAL AN EXTENSION
The extension range needs to be allowed in the Auto Attendant. For example, if most all of your extensions are in the 100 series range and you are trying to get to a 200 series extension then you have to have the option in the Auto Attendant (under Menu tree) for button 2 that says "Reserved in Dial plan".
If the extension is in the correct range then you should check to be sure that the extension is Dial Plan, Tables, Internal 3 Digit extensions (click devices using for older software). Make sure that extension is in the list (on the left for older software).
Voicemail password admin reset
The phone password has to be reset on the phone system (by the Administrator), not the phone. If you purchased phones and added them to the system, then those extensions wouldn't have passwords on them if they were newly added to it. If you purchased the entire system and phones then you can reset the phone passwords under "system maintenance", "password administration".
Lost web interface otherwise system is working
This does happen occasionally but is not a typical thing. This means that you have either lost network access to the system or a service on the system has stopped. The system will have to be rebooted to get things going normally again. The preferred method (since you can do it through netset) is to connect to the console port with a DB9 straight through serial cable and open hyperterm or putty and connect to it at 9800, 8, 1 none settings. Hit ctrl r and the system will reboot. if you don't have a serial cable then you are forced to pull the power or switch it off and then back on. CAUTION: you risk a database corruption every time the system loses power without closing the database properly (netset or ctrl r through the console) so do this as a last resort. Also, the system will do a disk scan (except V3001) and will take 15 to 45 minutes to complete before the system will start to function again. DO NOT UNPLUG IT AGAIN WHILE IT IS DOING A DISK SCAN! You can tell if it is doing the scan by looking at the S1 and S2 lights on the Call Processor. During a disk scan, they will be alternating back and forth (like police lights). Wait for it to complete and try netset again. I recommend doing a fresh reboot through netset after it comes back up just to be sure it's a fresh clean boot.
Tips on how to fix rj45 connector problem
Replacing the Patch cord is the easiest thing to do. If it is crimped on to the cable coming out of the wall, you should put a jack on it. To replace the clear mod plug on the end, you need another Rj45 mod plug and a crimp tool. These can be purchased at Home Depot, Graybar, Fry's electronics, Radio Shack etc. The crimp tool can be a little expensive but if you are going to need to do any more in the future, you'll have what you need. If you decide to put a Cat5e or Cat6 jack on it, they too can be purchased at the places mentioned above. You would need a punch tool instead of a crimp tool. Some jacks are tool-less but that is not the norm.
The sytem says its waiting for NCP and has the NCP
This means that the phone and the NCP (Network Call Processor) in the phone system aren't communicating with each other. Multiple problems can cause this. Things to check:
1. Network cable - Is it plugged in, and to the right port?
2. Phone died
3. Is there an available license? (3100 series phones)
4. Is there a network switch problem causing a loss of communication through whatever switch that the phone is plugged into.
In NBX 100 3COM phone
I know this is old but maybe it can help someone else.
The line cards are "hot swappable and don't always reset with a reboot (especially a Digital Line card) you should try to re-seat the Line card after the system has booted up. This is done by unscrewing the black knobs at each end and then sliding the card out about an inch. Wait about 10 seconds and plug it back in. It takes about 2 minutes for the card to boot and synch with the phone company. Try your call again. If it's still not working after about 5 minutes, check the card in the phone system and make sure the channels are idle. If they are, call the phone company.

Web page + 3102
You can't web to a 3102 phone, only the phone system. If you don't know what the IP address is on the phone system, you will have to get a serial cable (null modem cable) DB9 male to DB9 female and connect to the console 1 of the phone system. You will need a terminal emulator program and connect at 9600, 8, none and 1 for the settings. Type nbxIpConfig (case sensitive) and hit enter. The IP address will then be shown. If this is not what you were asking, please explain.
