Pricing:
$5 for a 'bundle' (this includes 1 switch unit, 1 power supply unit, and 1 power cable)
$3 for one of the (additional/extra) power supply units I have, and a power cable.
Since I have fewer power cables (that seemingly belong to these items) than the amount of power supplies, I can also provide some power cables that were meant for desktop monitors/computers.
I am not the original owner. They were used at the place I work. I don't really know much about switches, so my testing is pretty much limited to seeing if they powered on. Because of this, the items are discounted from prices of units you would find that are in confirmed working order.
For PoE, based on the manual I found on ManualsLib, it seems like that's a feature it has: https://www.manualslib.com/manual/1061927/Alcatel-Lucent-Omniswitch-6250.html
Alcatel-Lucent Enterprise OmniSwitch 6250 (Model: OS6250-P24) Network Switches
6 total units (currently in 3 sets/pairs of 2) with power supplies connected.
One of the units has a cable connected to the BPS port.
I have some power cables that seem to belong to these. Tested and they all work. I have 2 pairs. Each pair is bound together.
Alcatel-Lucent PS-225W-AC-P Power Supplies
8 total (currently in 4 pairs/sets of 2). They're currently connected in pairs of units. Each unit has a power cable connected. When plugged in to a power source, the fans and lights turned on.
One of them also has a cable that looks like the cable plugged into the BPS port of the switches.
There were a few additional cables that were among these and some other equipment. The cables likely belonged to these. You can have them if you'd like. They are:
2 cables that look like they go into the BPS ports
3 short ethernet cables. They're green. I don't know what category they are.
4 short cables that look like HDMI
Obviously, that's not enough for all the units. While supplies last, you can have one of each cable per unit that they would plug into.
Priority goes to whoever can pick them up first. When contacting me, let me know which items you'd like (and how many), your offer (if buying the untested ones), and your availability.
