According to the documentation, the Switches SFE2010P and SGE2010P have a maximun total power output of 360W. Using only SPA500 series IP Phones that have 10W maximun input, how many SPA500 IP Phones could be connected safely to this switches? 36 ? or 48 ?

View 4 Replies View RelatedI have 2 (and maybe soon 5 more) 7940G phones to add to my network, which already has a Netgear POE capable switch. I've since discovered that early Cisco POE isn't the same thing as current POE, and the switch doesn't power the phones.
I was looking at adding a Cisco SD208P 8-port switch to power the phones, but I soon discovered it only has 4 POE ports, and I'm not sure that this switch will even power the 7940G phones. And if the other 5 phones show up, I'll need two of those switches with no room for expansion on the voice network.
Will this switch power those phones?Is there another small switch available so I don't have to replace my existing switch infrastructure to get these phones to work? Or do I need to scrap the phones and get something newer that will work with the current POE standards?
how many PoE power from SG100D-8P ? its all 8 port support PoE ?

I am seeing the DHCP request hitting the router, and the router sending the IP to the phone, but it never gets the IP.

All ports are setup as trunk on vlan 2 including the ports that connect the switches together. Not sure what the problem is, but they are going live tomorrow and only have 48 out of 120 phones.
PoE works fine with C 1131/1141 Access Points and C-7975 IP phone but PoE does not seem to work on 7960 Phones nor on the C-1121 Access points
All devices work properly with the Cisco power injectors or on a Cisco Cat-29XX switch
Is there a trick to make PoE work for older devices ?
I want to connect a 6911 IP Phone to a SG 300 switch. This is my scenario: vlan 3 data, vlan 9 voice, vlan 10 admin.I have a trunk on port 10 of the SG 300 (vlan 1 untagged, vlan 3,9,10 tagged) and it is connected to a switch 3560, this switch has all the L3 configuration of the vlans and the SG 300 switch has an IP on the admin vlan (10).Also i added the OUI of my IP phones an created an LLDP Policy. Right now I have a 7941 IP Phone working but 6911 is not working. Iam using the new version 1.1.0.73 that supports CDP.
Also I noticed that even when my PC and IP phone receive IP address they can not ping each other nor the SG 300. They only can ping the default gateway or IP addresses in diferent vlans but connected on 3560 switch.
I have a question regard to switch SFE2010P, i have 2 vlan ( data and voice) and we want to configure Ip phones SPA502G, the question here is how can i make to suport 2 vlans on the same switch port, like the catalyst IOS switch port acces vlan x and switch port voice vlan x, if i set up the switch with the voice vlan like tagged doesn't work, but if i set up the voice vlan like untagged vlan its works but the PC attached to the data port on the SPA502G doesn't work?
View 1 Replies View Relatedi am looking at quoting the SF302-08P for a client which will have three small offices interconnected via single mode fiber. I am planning on connecting them to a 3560 switch. Each office will have no more than 3 - 7942 phones. I reviewed the notes on this switch and it seems it should support this phone type without any issues.
View 8 Replies View RelatedI have an ESW-500, a SPA525G (also tried 504G), Polycom IP330/670 phones, and a Switchvox (Asterisk-based IP-PBX) and CDP causes some issues.Both the SPA5xx and Polycom phones support CDP but it appears to operate differently between the phones. And, surprisingly, worst of all on the SPA's.
In short:
* Switch - CDP enabled (VLAN 100), DHCP disabled (Option 82 enabled) which is basically how it comes out of the box
* Polycom phones - CDP enabled (default)
* Cisco phones - CDP enabled (default)
* DHCP/TFTP server on port 1
* Phones on ports 7,15,19 - default as smartports for Desktop & Phone
* Switchvox on port 17 - port configured as General (not Trunk) with 1U & 100U VLANs. This was required to get Polycom phones to appear in Switchvox config
With that configuration the Polycom phones work perfectly. They appear in the switch web-GUI under CDP, they present in Switchvox and can be configured.But with that configuration although the Cisco phones appear in the CDP screen they do not get DHCP. My DHCP server can see 'DHCP Discover' messages but it just goes around in circles. Disabling CDP on the switch will allow the phone to get an IP but disabling CDP on the phone still has the same problem. When I saw "around in circles" this is what I mean....

With the difference being there's a 'DHCP Inform Msg' which there never is from the Cisco.I have tried many options regarding DHCP Relay, DHCP Server addresses, DHCP VLAN Interfaces, smartport settings etc but with CDP enabled the Cisco phone just will not get DHCP.
I have a CUCM BE environment with a number of remote users with 8961 phones connecting to an ASA 5501 via AnyConnect. The phones register fine and can make inbound/outbound calls as well as four digit dialing to other users at the corporate site.
The problem is when a remote user tries to four digit dial another remote phone. The called phone will ring but there is dead air once answered and then the line goes dead.
This sounds like a routing issue to me. How to get AnyConnect clients to be able to reach each other?
I am trying to hook up a SF300 switch to a cable modem and then plug some phones into the switch that are configured with static IPs. I am able to access the switch without an issue, but need it to pass traffic from the phones to the network and it is not doing so. We cannot do trunking because we are not using BSoD modems yet (next phase). For now, we just need the switches to pass everything from the phones to the network as is. Any ideas?

I'm having some trouble with a 4510 Switch Line Card. I need some recomendations for troubleshooting it.We have some PoE phones connected to the card number 3. When those phones were restarted, they did not go up again. In order to discard wiring issues, we connected the phone directly to the card 3, and the phone did not go up. If the phone is connected to a different card, it goes up correctly.
Additionally, to restore the service, these phones were migrated to other cards, but when we disconnect the equipment, ports in line card 3 remain in an up / up state (and nothing is connected to those ports!!), and only reflect the actual state after restarting the port.What steps could I do in order to troubleshoot this issue?. What should I look for, or how do I discriminate the problem? Might it be a hardware issue, a PoE issue?
I am new to VLANs although I generally understand the concept. I have a small office with 25 desktop/laptops and 15 VoIP phones connected with a SG200-50 switch and on Port 1 I have the Cisco SRP541W router for DHCP and Internet access. My goal is simple: 1) Segregate the VoIP phones (voice) from the computers (data) and 2) Prioritize the VoIP phones traffic.
I believe this can be accomplished by setting up a second VLAN and maybe a third (if the default should not be used) and then identifying those ports as Voice VLAN ports. I guess I just need to know how to flag each interface and each port so that they all can talk to the router on Port 1 yet the voice and data will be in different broadcast domains. Also, do I need a management VLAN??
Is this setup correct? VLAN 1 - default (data) Port 1 (Trunk) (Tagged)Port 2 - 30 (Access) (Untagged)VLAN 2 - voice Port 1 (Trunk) (Tagged)Port 31 - 48 (Access) (Untagged) What should the interface settings be on each port (General, Access or Trunk)? What should the port VLAN membership be on each port (Tagged or Untagged)??
provide a sample Voice Vlan configuration for the Cisco 2960 POE switch to work with the Non-Cisco IP Phones?
Will these commands work? Vlan 2 is the new voice vlan, Vlan 1 is the data vlan.

Even the SmartPort utility is useless - CCA (3.3.1 and earlier) gives an error saying a port is incorrectly configured (I pluggged it into an exp port on the UC560 as I gave up trying to get a working uplink to an ESW-540-24P).
The Smartport port function wants the exp port (on the UC560) to be configured as a "Phone/Desktop" - if I try to change it to a "switch", it refuses to accept it saying the "Macro is unsuitable - or similar"

2. Very quick flash of all RJ45 ports.
3. After about 30 seconds, any network devices connected have an acticity light
4. After about another 45 seconds, all ports light up including the activity and POE orange LEDs for about 5- 10 seconds then go off.
5. About 10 seconds later the ports all light up again and stay on for about 5 seconds.
6. All ports go off and the cycle keeps repeating continously.
I have tried pinging the switch without success.I have also tried disconnecting all devices from each port with no success.At no time does the system LED on the left light up.I have tried resetting to factory default with reset pot on the left side.This is a brand new shipped switch from our cisco supplier, could it be DOA?
I turned unplugged it and plugged it back in. Now its blinking green power LED. Is it dead?
