switch and heat 4

[dawg2]

I have an option 61c with 2 stacks 1 row with 4 pedistols and 2nd row with 2. We are doing work in our server room and they are changing out the AC. This weekend, what is the heat limit that a switch can take? and also because there is going to be lots of dust can we put plastic covering around the switch? Or would you suggest shuting down? Not ideal because we forward alot of extensions and have several OPS. Please advise.
Thank you, Susan

I would not cover or shut down. I would make sure to have fans circulating.

TEMP AND HUMIDITY
Recommended:
• 15.. to 30..C (59.. to 86..F)
• RH 20% to 55%, non-condensing
Absolute:
• 10.. to 45..C (50.. to 113..F)
• RH 20% to 80%, non-condensing
• temperature change less than 10..C (18..F) per hour

If you can get a couple of box fans you can position them so that they are pulling air away from the switch. They'll keep most of the dust away and help with heat dissipation.

Make sure you keep an eye on room temperature - if it gets hot enough in there, the overheat protection in each column WILL trip a breaker... and I've seen it where that overheat breaker trip also took out a couple of IPE power supplies along with it.

Also - I'd clean the filters in the pedistals first, and when they're done with the work in there, clean them again.

These PBX's are designed to withstand some gnarly conditions - so don't worry about dust or anything too much. But too much heat can be a problem. Because you are in a server room - try and shut down as much non-essential servers and network equipment as possible to keep the heat down during the changeover otherwise it will get HOT in there quickly without a source of cooler / fresh air.

Finally if you have a vendor maintaining your PBX, give them a head's up so they're aware.

Thank you for your responses. Where is the filter for the pedistals?
I do not have a vendor to notify, he went out of business.

Take the front grill off of the bottom by loosening the two thumb screws. It's between the blower and the bottom of the first shelf.

The filter is the same type of material you see in a filter for a range hood over your stove at home.

I usually take off the front pedestal cover and the cover to the first shelf - you'll see it looking down and slide it out carefully that way. There's little plastic tabs on the front of the filter to pull it out but sometimes they're there, sometimes they're not.

I usually blow the dust out of them with an air compressor and a good rinse with a garden hose. Let them dry completely before putting them back in.

Shop around for a new vendor ASAP. Phone systems are considered "critical infrastructure" and when the poop hits the fan at in the middle of the night and the PBX no more worky, then what? If your business depends on a working phone system for sales and customer service - a down phone system will have an hourly cost to your company in terms of lost revenue and customers. Service and maintenance plans are good insurance as some of our T&M customers have found out the hard way when their systems have completely failed. Getting *authorized* parts from Avaya is difficult when you don't have a partner/reseller to work with.
