5330e all lamps orange

[FargoTim]

I'm a new tech at a recent install who's experience is all with analog phone lines (and I'm really missing it right now!)

I have 3 HP 2920 48G PoE+ switches. Two are configured and online. The other is for a planned expansion. It is powered, but that's it. The phones are all Mitel 5330e's which had been used in a previous building.

Everything has been working fine since it was setup 3 weeks ago. Yesterday, for no apparent reason, 4 of my 6 Mitel 5330e phones quit working. I unplugged then Ethernet cable and plugged it back in, and every lamp on the phone turns orange/yellow and stays lit. The LCD screen lights up briefly but goes dark after a few seconds. No text displays on the LCD. I moved the patch cord in my server room to a different port on my switch but got the same result. The building had existing wiring, so to ensure it was not the wiring, I plugged a different phone directly into the switch with a brand new Cat 5e cable. Same thing: All lamps stay orange and no boot up. I eventually tried several different brand new cables and 3 different phones (one of which had worked last week) with no success. Here's the kicker (for me anyhow). If I plug the phone into the unconfigured switch, it boots and eventually displays Check LAN Cable/Settings. I presume because it is not getting a network connection from the switch which has no network.

The switch should provide up to 30w per port and a total of 730w across all ports. I did not find the exact specs on the phones, but I read somewhere that they are only around 5w each. I only have 6 phones, so I don't think its a power issue. I believe I have also eliminated any cabling issues by plugging directly into the switch with several brand new cables. The phones boot to a unconfigured switch, so I'm leaning towards a setting in my switch.

Any thoughts or advice for an old tip and ring kinda fellow? Is there something I need to tell the guy that configured my switches?

First, please provide more information: System, model, SW version. For example, SX200 AX ICP 5.0.2.12.

when you said you changed ports did you change to a port that had a working phone on it?

sounds like a power problem on the hp

someone may have messed with power settings on the individual ports or it may have developed a fault


If I never did anything I'd never done before , I'd never do anything.....

I had similar not long ago on a CXi 11; customers IT people plugged a WAP into the poe and it took most of the phones down on the switch. Unplugged it and everything was Ok again. So i agree with Billz66; most probably a power issue.

For the HP 2920 switch there are two types could you check the J number, J9729A has a 575w power supply and J9836A has a 1050w power supply.

As per other posts it does sound like a power issue or a fault with the HP, you can telnet into the HP and take a look at the error logs which should indicate if there is a problem.

Thanks for the responses guys. I am trying to find out the System, model, and software version from the tech in the office that has the equipment...once I find out who that tech is. Its great to be the FNG! xD

I was thinking a power issue as well. According to the HP manual, this thing should provide up to 30w per port and/or 730w across all ports (we only have a single power supply installed in each). The first switch is nearly full, but the 2nd switch only has 20 of the 48 ports used. Even if we're drawing the max power from each port we should be under that 730w threshold. There is a WAP, and I'll have to figure out where it is plugged in (documenting the initial install was supposed to be one of my first tasks). It could be that we are using all the power on the 1st switch and have the WAP on the 2nd switch. It is also possible that this is a power issue because when I plug into the CISCO router the HPs are connected to, the phones come up. That at least is a definite indication the issue is with the HPs and not the phone system.

Just an FYI, this issue has mysteriously fixed itself. The phone guy says he didn't do anything and the router guy says he didn't do anything. No clue what changed. I'll keep looking into it as time permits and update if I find anything out.
