Cisco WAN :: Power Requirement For 3845 With Two (2) Switch Modules
Aug 17, 2011
I would like to know if any additional power would be needed for a 3845 (currently with one (1) NME-XD-48ES-2S-P) to which another 24-port switch module is added. Thus, I would have two (2) switch modules on the 3845 for a total of 72 ports.
I have been unable to find specific power requirements detailing the requirements with 1 ethernet module, 2, etc.
I had already posted for voice modules for cisco 2811 but not able to find it. But here are a few questions regarding i
1. I am trying to configure a cisco 2811 with FXS ports . I am using an NM-HD-2V with a VIC3-2FXS. I am using the right modules. Also I believe we need PVDM mosules installed in the NM-HD-2V. We have PVDM-12 modules. Will that work or is 2811 compatible only with PVDM2-xx modules.
2. We are also trying to configure a cisco 2811 with PRI port. We plan to use an NM-HD-2V and a VWIC-1MFT-T1/E1. If they are correct and if we need only PVDM2-xx modules.
3. Also we are trying to configure a cisco 3845 with PRI and we plan to use the same as in 2811 that is NM-HD-2V, VWIC-1MFT-T1/E1. And here also we are not sure if we need only PVDM2-xx DSP modules.
I need 3925 router and i want to install SM-ES3G-16-P etherswitch module with PoE into it. So my question is do I need PoE power supply or not? Will PoE ports on this module work with basic AC power supply?
I found this "VWIC2-2MFT-G703 1841 - 3845 tied to platform slot density" from Cisco web site, does it mean if Cisco 1841 have two wic slots I can put two VWIC2-2MFT-G703 in this chassis.
I am looking the power requirement for 6506E in data sheet and it shows that is support 3000, 4000, 6000 & 8700W. I have currentely 4000W power source for my new 6506E switch. will it work with below modules in new 6506e ?
While configuring PoE Ethernet EHWIC PoE modules with ISR G2 routers Cisco DCT gives a warning to select AC Power Supply with PoE ‘PWR-3900-POE’. Do we need to select the PoE power supply for Enhanced EtherSwitch SM PoE modules also (at present it does nt show any warnings)?
I have purchased a new cisco router 3845 and i can`t start the router when i power it on in the normal mode either on the rom monitor mode.It seems it hangs up , the attached shows the last thing appear to me even if i plug on the second power.It gives no chance to enter anything in both modes.
I recently ran an upgrade on my 6509-E's and when the first switch came back up, 3 of the 10/100 switches that were in the chassis did not power on. After further investigation, these models are not supported by this latest IOS version. The module # is : WS-X6248-RJ-45
We have one WS-X6348-RJ-45 and since it was a few weeks ago I did this I can't remember for sure but I believe this one came up.
Where can I found the information regarding this being unsupported but I know it is out there and any page that showed me that this was unsupported with the latest stable IOS of 12.(33).
In addition to this question, I have approval to purchase some newer gigabit switches that will be supported by this new IOS version and hopefully at least the next few over the next few years. Which specific gig models are currently and hopefully should be supported for the next few years? I don't need PoE or anything spectacular, just regular switches that are attached to either servers or virtual hosts. I've been looking at the lists of what is out there and it seems like there are hundreds of different models and it is becoming difficult to determine what is what.
I can ping to both devices using Virtual ip address.The work around to solve the lines "Active router is unknown and Standby router is unknown " is to delete the hsrp configuration in Standby device, after that the problem is solved but is happens again after some days.The problem is that i don't have access to Foundry switch but i think that HSRP configuration don't have any problem, even in Log Buffer i didn't saw any problem related with HSRP.
Is there any physical or technical diferrences between PWR-3845 AC/2 and PWR-3845 AC? We are trying to order replacement parts and wondering if PWR-3845 AC is for one power supply and AC/2 means you get two with one order?

I am dealing with cisco networking and am using cisco packet tracer bt i want to configure router but when dragging modules (ports) it tells me you cant drag modules when power is on
I have a customer who is concerned with the power draw on the new switches we're deploying.They only have 20 amp breakers in their closets and fear popping them on switch boot. The customer is under the impression that a switch will pull full power on boot. So a 3560X with an 1100w PSU will draw the full 1100w on startup. Ive never heard this and it doest make much sense to me, but I need to verify.
In the Power Schedule section, when I input my desired date and time to turn a socket on and off, the settings do not stay. It reverts back to the preset date from the manufacturer after I submit.
We have 2 of the SG200-26 switchs. When ever we loss power all the settings are reset to default. Even if we loss power for 1 min. This includes the IP, user, password, etc. How can I change this so the settings are saved?
We have configured Cisco 3750X POE series switchs with Stack.WS-C3750X-48P each with Redundant 1100W & 715 W PSU's. They are configured with Stack-Power in Sharing mode and the switches are Smart Stacked as well.IP Phone and Access points are connected its working in last two years,
Now we are facing some issue on Cisco IP Phone and Access point, When i have problem if unplug (disconnect & Reconnect) the IP Phone from Switch port,Power is not comming on switch port.Plug it into another switchport of the same Switch it may not power in any port.I tried shut & no shut and reconfigured on switch port , I have verified multiple switch ports same issue on the switch I have changed cable.
recently a Cisco 3560E switch went down due to a power surge. the switch is getting power but i am only seeing the below message continously. it is keep on rebooting. i try to reset to factory settings/ safe boot nothing worked. is there any way i can bring the switch up or it is hardware failure.Using driver version 1 for media type 2Base ethernet MAC Address: 00:23:33:af:1b:00Xmodem file system is available.The password-recovery mechanism is enabled.Using driver version 1 for media type 2Base ethernet MAC Address: 00:23:33:af:1b:00Xmodem file system is available.The password-recovery mechanism is enabled.
Can a Cisco SG300-10P switch power a Cisco SG200-08 switch over POE? Or an SG200-08P power an SG200-08 via POE? I have an area where I'd like to put a small switch, but would like to avoid having to have electrical power run to it. Or will the SG300 and SG200 POE switches only power endpoint devices such as cameras and IP phones?
I have a 6509 that has dual SUP32's.Just want to make sure and give a reason(if there is one). Slot 6 always becomes the active hot on a full reboot. Meaning from no power to the whole switch to powered on. What is the election process for Supervisors?
I have an issue with a 3560 in my network, after sometimes it fails to give out power to some ip phones,while others are not affected and below is the message i get
"Power given, but Power Controller does not report Power Good"
output of sh power inline and sh env all : everything seems to be ok on the switch

It's solved by a reboot of the switch, i could have suspected a power environnment issue but it's the only equipement disturbing in the network.
I'm using a Catlyst 3550 to supply power to a IP network surveliance camera. By default, the predecesor to POE, Cisco Inline Power allocates 15.4 W of power to a port ... What is the process for reducing this power output?
"For an IEEE device, the switch always allocates 15.4 W to the port. The switch does not display the IEEE class type in the show power inline privileged EXEC command output. Instead, it displays n/a."
We got a new Cisco 2911 router (CISCO2911/K9) with a switch module (SM ES2-16-P) on it. Everything works fine after the configuration except for the power. We got 4 WAP that we will connect to the switch module that needs power. So the switch module with POE doesn't give any power out.
my laptop always automatically disconnects from my wireless when I switch to battery and unplug from the power cable. I then have to restart because my laptop doesn't find any wireless adapter installed.
i just got a couple of these units delivered but have problem. the power supplies (j8712a) have this plastic insert key between the 3 prongs in the female connection. The cheapest nema 5-15p to iec c15 power cable I found in usA coincidentally is through hp for $23.75usd plus shipping (hp part 8121-0973): [code]
I have upgraded my C3560-PS-S switch to the latest IOS version 12(2)55-SE4 and it is not providing PoE anymore? It used to work before this upgrade? I searched Cisco bugtrack and there is bug defined for this IOS/Switch.

We have one switch 4510R which could have total 300 cisco GE color phone connected. That means 300x15.4=4620W. Considering the 89% effiency for the PoE line cards, that means each line card needs 5191W input power from chasis power supply. Based on the 6000W power supply specs, only up to 4800W is allocated for PoE purpose. But we need 5191W from power supply which redundant mode can't offer. We don't want to go with combined mode. So should we add external power shelf to add more power?Another question will be how much power we need from utility or UPS. For example, the efficency of cisco power supply is 75% and we use two 6000W power supplies in redudant mode. Then we need 8000W. The voltage is 220V. Then the AMP we need is 36.4A from UPS or utility power.
i have one of my switch modules that shows PwrDown when i issue the command show mod.

i tried disabling the diagnostic monitor for the module, did a power enable module command and then reset it but it still fails. this is the third blade that i am replacing in a few weeks and i still get the same error. i am persuded that it is not a hardware since it is the third blade in a matter of weeks. after the module reset, i receive this error % module 3 is operationally off (FRU-power failed)
could an ios upgrade solve this issue? are there any ios related bugs?
