PoE alternatives

Anyone use third-party PoE midspans for powering phones? Particularly
with a 2950/2960 switch?

I typically have been installing the PoE version of 3550 or 3560
switches for phones. However, I am entertaining the idea of using a 2960
switch with a third-party PoE midspan, because it is much cheaper and we
do not really use any of the layer-3 switch features anyway. I also have
some future phone installs coming up where there are several existing
2950 switches already in place. In particular, I am looking at
Microsemi/PowerDsine for midspans.

If anyone can provide their thoughts/experiences with such a setup, or
other alternatives, I would appreciate it.

P.S. I am aware of the new 2960 model that has PoE, but it is not
available in 48-port nor with 1000BaseT uplinks, so by the time I buy
two and put SFP modules in, a regular 48-port with midspans is still
appealing.

We have been using Linksys SRW224P switches. 24 Port PoE with QOS for
under $500. The downside is that they do not understand CDP.

a couple of PowerDsine midspan bridges here and there.

Re: PoE alternatives [In reply to]

Hi, Norton.

Why not to use CE500 or 2960 with PoE in such cases?

Kind regards,

Hi

What about Cisco CE-500 and 502 series, they are really cheap compared to 2960 & 3560 ?

Khalid
