is it safe to disconnect fibers for less than a minute?

[modulistic]

Im in the process of moving a 3300 and 4 per. nodes off of a table and onto a rack. the fibers are all coming out of FIMs and they are pretty tangled up because we had to rearrange the peripheral nodes. customer was wondering if we can unhook the fibers for a short while, untangle them, and then reconnect them. will things blow up? will everything come back up as normal?

I would recommend doing a system backup and then shutdown the system before moving. There is a hard drive in the 3300, I certainly wouldn't want to start moving it around while operational. Once the system is shutdown, then you can unplug the fibers no problem.

Just remember which one is which! Sometimes the obvious has to be said.

When doing work like this where the customer wants to have a working system when things are being changed and moved, I always tell them that you have to crack an egg to make scrambled eggs.

roger. you bring up an excellent point.

only problem is its a hospital that in order to schedule a shutdown, myself and the hospital IT guy have to jump through like 2342039849039293843 hoops to schedule downtime, and my management have shut down any overtime for myself, so this is the way its going. right now the 3300 is sitting on the floor.

I guess Ill backup the 3300, pull one node and see if it comes back up tomorrow.

Well, I'm sure you will be careful. I have never taken a fiber out of an active system, so I am unsure of what exactly will happen other than the obvious that the per node and all its circuits will be inactive. With that said, I would recommend removing power on the per node first, then disconnecting the fiber, move the per node/untangle the fiber, reconnect the fiber, and power up the per node. The main system will stay up, but you will see alarms while the per node is down.

If it is a hospital then you will have redundancy so it would not be a problem to shut one 3300 down

If you don't move ICP, you can turn off periferial unit, disconnect cables, move your suff, reconnect cables and power on. The unit should come up. Sometimes it doesn't. You should negotiate some comp time with your management when you can take some time off after you worked nights.
I don't want to be a patient in there. Sorry for this 2c.

Re-read my last post and realized I said to first power ON the per node. I meant power OFF.

tlpeter... redundancy is in the 2K is it not? The 3300 offers resiliency with IP phones. And if they have 4 per nodes, then I am thinking that they are using digital or analog sets which would not be resilient. Also, the redundancy in a 2K would be within the same cabinet, so you still have to physically move the whole cabinet.

 

[tlpeter]

I do not know about the 2K
I am not that experienced in Mitel
I forgot about digital and analog phones to be honest
But still in a hospital i would at least use two MXE's
When one fails you can switch to the second one

well, for future reference, you can shut the per. bay off, disconnect the fiber, move the fiber, power the bay back up and only have a few seconds of downtime.

A few seconds?

I would expect 2-3 minutes for the Bay to load.

it seemed like seconds. maybe it was a minute or two. honestly we were doing 3 or 4 other things while the bay was booting back up, I just happened to look over and see that folks were making calls pretty quickly afterwards.
