IP Office 500 Control Unit Questions 2

[AvayaRedDude]

I've dealt with a couple IP Office 400 Control Units where both were damaged by mild or freak thunderstorms. One of those control units did start to smolder and when plugging it for experimentation months later as it was totally decommissioned, it totally started to smoke up.

I was wondering if this was the same issued that plagues the IP Office 500 control units - especially in environments where the electrical may be sketchy or the grounding may not be perfect. I do not need the preachin', just wondered if this thing is known. Given the power supply using three prongs and the grounding that appears to be in the internal power supply, would this help? And is the V1 similar to the 400 with the power brick and V2 is the one that has the 3 pronged cable?

To put this into perspective, I have situations where I have servers, and other high grade equipment and they haven't had been damaged by freak storms.

Secondly on the software front: On the older 400 control units, the basic software was internal on it's chips. Looks like the 500 has SD cards/RFID card thing depending on V1 or V2. So does that mean it needs a card to run anything?

Looking for a reliable unit to do basic VOIP and analog trunking, since the wiring in the quasi residential plant is all Cat5e. Cisco and Asterisk can gag me (in my opinion!)

Thanks for answering my questions in advance!

Servers typically connect to the network and power only, telephone systems have lines directly connected that come from outside the building and if analogue and dig phones are used many more cables directly connected that span a large area, this means a telephone system would typically always take hit several times higher than a server ever would, easily into the hundreds of thousands of volts

^ Let's put it this way:
1F trunk is via a cable provider that is tied to a modem.
I've had other phone systems in similar locations not having this problem. Similar situation, modem providing the analog trunk...
Can someone confirm reliability/safety via an analog trunk from a Comcast type of service?

Interesting thread.



daddy? are you doing blah blah blah things again?

The IPO installation guide has a section on Lightning Protection/Out-of-Building Connections for your own circuits so I assume the telco would have something similar, there's also a section on grounding which is separate to the power supply. A server may be behind a UPS which might offer some protection.

The IP0500 does need an Avaya card to function even if there aren't any licences. On the IPO400 the dongle is optional and needed only for licences. The dongle can be serial, parallel or USB attached directly or to a PC depending on the model.

Interesting thread.

So how can I protect (other than getting an electrician to come in) such as those IROB gadgets? I've read those are also used to protect analog trunks too?

What happens if the control unit is in another location than where the modem is? The wiring closet is in one area, the modem is upstairs in another room. How do I tackle that if I felt using an IPO 500?

Stole my thunder (no pun!)

Good to know on both parts. I don't have licenses, but I do have some old parts from the IP Office units that got fried I could transfer over (like the VCM5.)

Is there a licensing structure on phones/trunks and concurrent calls? Not familiar with post 400 control units. The setup would be about 6-8 terminals, 2 trunks, and a couple concurrent sessions.

DONT DO IT!
when equipment has suffered a lightning strike all attached components should be considered suspect

they may appear to work now but you have no way of telling whether or not any components have been damaged are weakened, it is probably only a matter of time before i fails as well.
