The Basics and Examples - USER MANUAL
Posted: Tue Oct 14, 2014 1:36 pm
I made an hour and a half tutorial, click HERE to view the movie.
The firmware is not finished and we hope with support from the forum community we will get there soon and add some features that you request.
Some Basics:
Default IP address: 192.168.1.20
Default username: admin
Default password: admin
Serial Console: 8, N, 1, None, 115,200
If you serial console into the switch for now you are at the Linux shell, however if you type “switch” and press enter you will get into our command line interface (CLI).
We plan to make this the default landing pad eventually where you would type in "CMD" to drop to the linux shell and type "Exit" to return to the CLI.
PLEASE DO NOT COLD DEAD SHORT TEST THE POE.
ESPECIALLY AT 48V OR 48VH AS YOU WILL DAMAGE YOUR SWITCH.
I can not stress the importance of making sure your cabling is correct before you apply 48V and 48VH. The best thing to do is before you apply power do a cable diagnostics from the web UI and make sure there is no cross pair shorts.
100/1000 Mbps 48VH devices like AF24 and AF5 will show all pairs OK or OPEN.
10/100 Mbps links like the SAF 106 will show pairs 1 & 2 as OK or OPEN and pairs 3 & 4 as short but NOT cross shorted.
10/100 Mbps airMAX 24V devices will also show pairs 1 & 2 as OK or OPEN and pairs 3 & 4 as short but also NOT cross short.
You might also consider initially powering the device with a brick to make sure your cabling is correct then after you verify all is OK then plug the cable into the switch PoE port and then turn the PoE on to that port in the UI.
Remember if you are powering your entire tower with one switch and you damage it then you're in trouble!
It is also advised that you turn PoE on and off in the switch and NOT unplug and plug cables in to energized ports, especially 48VH ports because the MOSFET circuits increase current slower than plunging the cable into a switch port that already has PoE turned on reducing the in-rush current load.
This is more important with the 48VH devices than the 24V lower current draw devices like airMAX radios.
If you plug in an RJ45 connector incorrectly it can cause a momentary short across pins or under the right circumstances an arc across pins which could cause damage to the switch.
Experiment with the WISP Switch UI's cable diagnostics tool in your shop to get a feel of what different devices will look like so you can test the cable to PoE devices when they are plugged in before you apply power to the port.
Maybe have a meeting with your installers and discuss procedures to check new cable runs or jumper to a PoE device with the cable diagnostic tool before you turn the PoE up on that port. You could even run the cable diagnostic tool on some shorted test cables WITH PoE OFF OF COURSE. It is a great tool why not use it!
We plan to add some software features to HELP prevent a “cold” dead short but we ran out of time and wanted to get these out into your hands. A “cold” dead cable short is far more dangerous to the switch than a "warm" short as poly-fuses work on heat and if they are already passing current and warm when a short occurs it is far less likely to damage the switch as a warm poly-fuse will trip much faster than a cold poly-fuse.
However it is always possible to damage the switch from any Ethernet cable short, primarily the Ethernet Transformers get damaged first. We got the highest current rated transformers we could find which are 720mA per pair. Passive POE and higher current draws were/are not in mind when they design Ethernet transformers but we will keep looking for higher rated ones. Remember that is 720mA per pair which means the 48VH which uses all four pair should be good up to around 1.2 to 1.4 Amps or 60 Watts +/- at 48-50V. I have been seeing our AF24 on average pulling about 47 Watts with 200' +/- of Ethernet cable in front of it.
If using the console in the web UI we are aware that it is a little sluggish and we plan to speed this up as well as improve the CLI with all your suggestions.
There is a small unmarked hole on the front of this switch which is the reset / factory default button where you can use a small object like a paperclip to press it.
To simply reset/reboot the switch
Press and hold the button in for 5 seconds until all the green lights on the front of switch loop around then release the button and the switch will reset.
To factory default the switch
Continue to press and hold the button in for another 5 seconds until all the red lights on the front of switch loop around then release the button and the switch will be factory defaulted.
I will make posts here to show example configurations to explain some things in the switch UI.
