The picture of the device in the PDF sure looks more like a four port/device
product than an eight port/device product.  It only shows four (1-4) LED
indicator lights and it appears the top four ports are labeled as "Data" and
the corresponding bottom four ports are labeled as "POE".  This leads me to
believe it functions more like four PoE or DC injectors in one box than an
eight port switch.  

IMO, a design like I describe would be more desirable anyway as many
operators dedicate each backhaul radio or AP to its own port on a router
anyway.  We do not tie any of our radios at HUB sites to a common switch.
We use multi-interface x86 MikroTik routers at HUB sites or RB493AH routers
and route each sector or backhaul radio on its own port.

I like the voltage flexibility it offers (12V-58V) and the ability to use
redundant power supplies.  What I'd like to see is something similar to
this, but in a compact, shallow depth 1U form, higher port count (maybe 12
or 16 ports) and the ability to reverse polarity via dip switch or jumper
setting on a per port basis.  It also doesn't have to be an active Ethernet
device (just another Ethernet chip to worry about failing), but make it a
passive Ethernet pass through like most DC injectors are designed.

Best,


Brad

Hi all,

I saw this interesting switch which is has NON stardard POE, i.e. good
for 12-24V devices:

http://tyconpower.com/products/files/TP-SW8_POE_Switch_Spec_Sheet.pdf

It seems a good idea instead of multiple POE (but also a single POE, is
a single point of failure...)

Anybody using it? Comments?

Thank you
