trouble with 1120e sets

[Racecartim]

The IP phone works if plugged into the switch with a patch cord but not if plugged in at the jack, the jack passes just fine with the tester.

I have went into the switch and started to mess with the negotiation settings and hard coded the port for 100 Mbit full duplex and they came back up. I think this is my issue i am having with these phones.

Has anyone else had issues with the Nortel ip 1120 phones and auto negotiation to the network switches?

I found this below.

Nortel recommends that any Layer 2 or Layer 3 switch ports connected to
the ELAN or TLAN network interfaces be set to Auto-sense/Auto-negotiate
for correct operation. Although full-duplex is preferred, it is not required.
NN43001-260 Refers

Duplex mismatches occur in the LAN environment when one side is set to Auto-negotiate, and the other is hard-configured. The Auto-negotiate side adapts only to the speed setting of the fixed side. For duplex operations, the Autonegotiate side sets itself to half-duplex mode. If the forced side is full-duplex, a duplex mismatch occurs.


All the best

If it's working, then leave it alone!.

You said the phone works when plugged into the switch but not when plugged into the jack, so why would you do any changing with the switches at that point and instead take a look at that jack or try the phone at another station location? Am I not understanding this right?

Are you running any PC's through the sets ehen plugged into the jacks? I have seen this become an issue at a few sites when not provisioned correctly. Also make sure somehow you are not also set as a DHCP server while their DHCP server is running as I have in one instance seen it NOT knock down the network but in fact the 2 servers kept fighting over who was going to hand out the addresses. Just a thought.

How do i log into the 1120e set and do changes to the data port of the set, i am looking for a settings for negotiation to hard coded the port for 100 Mbit full duplex

If it works at the switch but not when plugged into the wall jack then your wiring is bad. End of story.

Unless your testing device is a multi thousand dollar network analyzer it's not capable of verifying that the cabling is good enough to support the required speeds. The 1120e set is capable of gigabit network speeds but if your wiring is marginal it will fail. You might be able to temporarily work around the bad cabling by hard coding the link speed of your switch and device down to be slower but that's not really fixing the source of the problem. Use different patch cables, and re-terminate the jack. If you have access to a good network analyzer you can get info on the maximum frequency supported by your cabling. A really good analyzer can even tell you how far along the cable any source of problems is being detected. If your tester is only doing a simple continuity test then it's not capable of detecting more subtle faults and verifying performance of your cable.

Someone else asked if you have tested the phone on a different jack. Did you?
