Cisco Switches :: SD208P - Does Not Seem To Power PoE Devices
May 3, 2012I have a Cisco SD208P. Is this a PSE of type A or B (endspan or midspan)? The switch does not seem to power PoE devices via the data pairs only.

Aug 15, 2011I have installed my new E4200 and it works beautifully. I have several wirelss adapters and a few wired connections through powerline adapters. I also have a second VPN router attached to the 4200.I can see the wireless connected devices with the associated IP addresses. If I plug a laptop directly into the Cisco, I can of course see it.However, I can see none of the devices attatched to the powerline devices? I have a securty cam connected via the powerline and want to know the IP address. I checked with cisco technical support via chat and they said it is impossible. I have used 2 previous routers with the same configuration and can see all devices.

Dec 3, 2012I have a SF-300-48P that is power cycling all POE ports (in use) exactly every 30 minutes. The other older cisco POE switches we were replacing did not have this issue. We have about 40 cisco SPA942 IP phones connected to it. Power consumption is about 175 watts total.
This is my second switch, previously tried a SG500X-48P with the same result.
how to stop it from cycling?

Jul 17, 2011Does the power save feature of the SG 102-24 can be disabled somehow ? Our college just purchased 24 of these switches. We are having a problem with the switches affecting some of our monitoring software (Vision from Nettop).Basically, the client pc's become invisible to the master station. I believe this is due to the ports doing an automatic shutoff.I know these switches are unmanaged, but I'm hoping they at least have some form of configurability. Right now our only option is to have an instructor cycle the power of the switch to get the client pc's visible again.
View 3 Replies View RelatedCisco Switches :: SG300-28P - POE Power Drops Every Several Minutes
Sep 10, 2012We have an SG300-28P which, at intervals between 5 and 30 minutes or so, drops power to all of its POE-powered ports and then immediately restores power. The switch logs nothing when this happens other than recording that the ports went down and back up, even with debug logging enabled. Non-POE ports are not affected.
When the problem started there were only four POE-powered devices on the switch and we are far under our power budget. (While testing I added a fifth device, see below.)
Not all combinations of devices cause the drops to occur -- specifically, it looks like having devices on ports near each other causes the drops. When the drops occur, the absent counters of all of the POE devices increment. I noticed this earlier thread here seemed similar: [URL]
but in that case, he got no power at all in the adjacent configurations, instead of having it drop every several minutes.

Jun 23, 2011I just purchased a SG200-50P switch to replace a WS-CE500-24LC, that had a limited amount (4) of PoE ports. I was running Cisco 7940 IP Phone, Cisco AP1231 and AP1100 series access points via PoE off of this switch.
When I attempt to plug in these device types into the SG200-50P they do not power up. What is going on? Why do these devices (7940 IP Phone, 7960 IP Phone, AP1100 series access point, AP1231 series access point) not get PoE from the SG200-50P switch?

Cisco Switches :: Not All SG300 Ports Supplying Inline Power?
Feb 26, 2012Essentially, not all ports on our brand new SG300-28P switches provide Inline Power to our older 7900 series phones. I can connect the phone a couple ports down and it usually powers up, but not always. Often I can also connect an 802.3af device to one of the troublesome ports and it will received power, however I am noticing there are some ports that now refuse to supply PoE at all?
This is equipment that has been running perfectly fine for several years now, on C3524 PWR XL switches. I can also tell you that this is not isolated to one switch, but all 5 of our SG300 access switches. And, yes, the firmware has been updated to 1.1.2.0.
Cisco Switches :: SG 200-08 All LED Lights Flashing Green After Power Failure
May 5, 2012Thinking back, about a month ago I updated the firmware (I can't check version at the moment). The switch has been working fine since then. Today I needed to move some power cables and the switch lost power. Now ALL of the LED lights are flashing green and I can't access the switch. I've tried setting a static IP on my laptop to 192.168.1.20, mask 255.255.255.0, and accessing the switch on 192.168.1.254, but there's no response. I've tried holding in the reset button for at least 30 seconds while the switch is powered on, AND while powering it on. None of that has worked. Also when I first power it on, the system LED flashes orange very quickly for a second or so, then all of the LEDS start flashing green.

Cisco Switches :: SG-200 To 887 Setup Trunking Between These 2 Devices For Multiple VLANs
Mar 28, 2012We have a Cisco 887 router and a Cisco SG-200 switch.We'd like to setup trunking between these 2 devices for multiple VLANs on the switch to be made available on the router.
With previous routers, you could set the router up in the configuration 'router-on-a-stick' and VLANs worked like a charm but the 887 no longer support sub-interfaces.So how can you get trunking working between the 2 devices?
Is there a VTP configuration menu for the SG-200 which we can setup in order for it to talk 'VTP' with the 887 router??
Cisco Switching/Routing :: 3560 - Portable Redundant Power System For Catalyst Switches?
May 10, 2012Does a portable RPS device either from Cisco or another manufacturer exists, that would allow you to move primary power for a switch without causing an outage? I realize that for the Catalyst 3560 for example, you can get an RPS 2300 or 675, but my understanding is that these are made for a more permanent installation, not to mention rather costly.
It looks like the RPS 675 is rather inexpensive after all, especially in the secondary market, but still rather large for toting around.
