Hey Guys...<br>
<br>
A customer of mine needs to replace a bunch of non-PoE 48-port switches<br>
with PoE switches. Each of the switches will be required to power 48 IP<br>
phones. Due to a range of circumstances all relating to planning<br>
failures we need to use like-for-like form-factor ($n x 48 Port PoE<br>
Switches) to drive the phones.<br>
<br>
The phones are Polycom VVX 500 that draw a maximum of 5W per port for a<br>
total of 240W per switch. We've bene looking at 2960's and this fits<br>
nicely within it's 370W PoE budget. However, the .3af advertisement from<br>
the phone gets interpreted as Class-0 (15.4W) and the switch will only<br>
power >= 28 devices concurrently.<br>
<br>
On the Catalyst we're able to get around this (I think?) with the `power<br>
inline max` config directive to force it to spread the power budget<br>
across all ports.<br>
<br>
For what we're trying to do a set of 2960's will come in around $25k.<br>
<br>
My question is: Can any of you guys suggest cheaper switches that will<br>
allow us to run 48 x 5W PoE from a single device with the ability to<br>
ignore the 15.4W .3af advertisement that will tell the switch to shut<br>
down the additional ports?<br>
<br>
<br>
<br>
Cheers,<br>
T<br>
