weeks ago and I ran it past my SE. The Gig phones require twice the power of
the non-gig phones and therefore you can only run 24 gig phones on a 48 port
PoE switch…. Leave it to cisco to come up with such a great design…….
NOT. Basically I got the impression that if you were going to use all Gig
phones to buy only the 24 port switches. Ci$co.<o:p></o:p></span></font></p>

do they need when they are with inline power from the switch? In the
specifications of the phone it says:</font></tt></span></font><img width=19

<span class=content><b><i><span style='font-weight:bold;font-style:italic'>"48
VDC, 0.2 A—when using the in-line power over the network cable"</span></i></b>
(so does it need 48x0.2=<b><span style='font-weight:bold'>9.6watts</span></b>
to work?) . </span><br>
<span class=content>I must use the command <i><span style='font-style:italic'>"#power
inline static max <milliwatts>"</span></i> to restrict the phone
from drawning the maximum power which is now 12.9Watts (as shown by show cdp
neaighbous detail) and so it reduces the maximum number of phones the 3560 can
support (after i put 27 phones it could not give any more power)?</span><br>
<span class=content>2. For a 7971, i also plugged the power cube but it
continues to drawn 15.050Watts!! AC power adaptor cannot cover it's needs for
power and so it would not have to drawn any power from the POE switch?</span><br>
<span class=content>3 Can i use a RPS that i have on site and configure it to
give extra power to the switch to support 48 phones of any kind?</span><br>
<br>
