CIsco switch 3524 and 7961 issue

[Marlo De Ocampo]

Dears 

I have issue with Cisco  7961G connect to cisco 3524 XL switch.

I found that the phone doesn't get POE , so  i get external Power for it.

so now I connect the phone to this switch   and phone get the external power .   the port of the switch is NOT blinking   .

I try to register the phone to CME router  ( I upload the firmware to flash )  but the port itself not blinking .. i try with different ports.. but it still the same.

is there any idea to resolve this issue.

thanks

Hi,

You need to look at port configuration.

can you please post the output of switch port config?

Thanks

[Marlo De Ocampo]

is there any one can help me out in this issue?

[Carlo Poggiarelli]

Hi.

Sorry for delay

On fa0/11 add this config 

speed 100 

duplex full

switchport trunk encapsulation dot1q

switchport mode trunk

Let me know

Regards

Carlo

[Marlo De Ocampo]

Hi

thank you for cooperation

still NOT work

the port not blinking

[Mohammed al Baqari]

Hi,

I am not sure if the phone is faulty or not getting the right watts from the external power supply but the switch port is showing disconnected which means that the switch isn't sensing the carrier signal from the phone.

Do the following

1. Apply the following commands:

config t

logging monitor debug

logging on

default interface fa0/11

interface fa0/11

switchport mo acces

sw port access vlan 1

sw port voice vlan 1

no shut

speed auto

duplex auto

2. turn on 'term moni'

3. Unplug the phone and plug it again

4. Check what logs popup on the switch

[Richard Bradfield]

Have you connected the Ethernet cable into the correct port on the phone?

do any LEDS light on the phone when you use the external P/s?

what is the external p/s output? should be 48VDC

also the 7961G will work with pre-standard poe which is supplied by the 3524 as long as the model is 3524-PWR-XL

[Marlo De Ocampo]

the power external is 48DCV and the phone get power from the external and the phone screen shows that it try to make upgrade. 

and this is version of the switch

cisco WS-C3524-PWR-XL (PowerPC403) processor (revision 0x01) with 8192K/1024K bytes of memory.

[Richard Bradfield]

ok the 3524 will support poe for the 7961G

please do a show power inline to see if power available.

you are using an Ethernet patch cord with connections as pre-standard poe uses unused wires

[Marlo De Ocampo]

dear 

in the begining when i connect the phone to the switch , i found the phone not working at all  and the port of switch NOT blinking , nothing appear on the screen.  so  I buy external Power for this phone 48DCV.

Now ; the phone have LED and the screen shows that  it try to upgrade but the Cisco Switch PORT is NOT Blinking .

so why the port is not blinking.?

i  use straight  cable  for the connection.

[Marlo De Ocampo]

dear

i follow yours steps  and nothing popup   on the switch screen.

the power external is 48DCV  and the phone get power from the external  and the phone screen shows that  it try to make upgrade.

[Mohammed al Baqari]

Hi,

 Change the cable. If didnt work then phone might be faulty
