And I want to get it up and running with the least amount of down time.
How about I install the switch but not power it up, transfer all the cables, power it up?
This way I can get it going in less than 1 min. (the AF24 & AF5 will take a bit to boot and acquire).
Yea you can do that I suppose but the I would not do it that way and I own a pretty decent sized WISP myself. I would power up the switch, connect my laptop to it and re-configure it the way I want it but leave POE OFF. THen move 1 device at a time on to the switch and run a cable diagnostics from the the Status Tab and if no "CROSS" shorts are detected then power up that port.
Remember normal airMAX Radios will report as follows:
No POE power:Pair 1: OPEN or Abnormal Termination
Pair 1: OPEN or Abnormal Termination
Pair 1: Short <== THis is normal as UBNT bonds the pair together
Pair 1: Short <== THis is normal as UBNT bonds the pair together
POE power ON:Pair 1: OK
Pair 1: OK
Pair 1: Short <== THis is normal as UBNT bonds the pair together
Pair 1: Short <== THis is normal as UBNT bonds the pair together
Cable Diagnostics is found on the Status Tab by clicking on the little gear to the far right of each Port Status row.You should fully EXPLORE the Switch UI on a bench before you try and deploy it. Click on everything and see if it is a link.
I always prefer that people do not un-plug and plug POE ports with live POE but there is nothing wrong with plugging the radios into a switch that is not powered up then plugging the switch in.
However this assumes that all the cables are KNOWN GOOD. Normally I prefer people run a cable diagnostics from the the switch UI to insure no cross shorts exist across pairs before powering up because a cross short will damage the switch and or the radio. BUT since these are know good cabling I suppose the risk is minimal.
Cross short and lightning damage to the switch is not covered under warranty but we will repair it for a fee.
However what most people THINK is lightening surge damage is 99% of the time because the tower ground system is not connected/bonded to the electrical system earth ground and the ground potential difference is what tears out the the Ethernet port.
ALWAYS BOND/CONNECT YOUR TOWER GROUND RODS TO YOUR ELECTRICAL SERVICE GROUND RODS.
