Cisco LAN :: Power Supply Requirement For SM-ES3G-16-P
Jul 1, 2012
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?
After stacking two 3750X switches, with four equal power-supply's, with StackWise and PowerStack , still got the next message every few hours %PLATFORM_ENV-1-FRU_PS_ACCESS: FRU Power Supply is not responding (gn4m-rt1p08-04-2)( note that the message revers to the second switch in the stack ) although the stackwise and powerstack on the switches is oke and are working correctly. !
Config : Stack-power in power-sharing mode/strict With CLI on the switch : All the power supply's and stack-power details, prio look OK.
Only: LMS prime /inventory/cisco-view/configure/power supply status result : some power supply's are marked as disabled.with the command > power supply 2 slot a off/on I manage to get the status back to "normal", but after a few hours some power supply's are again marked as "disabled".
In a stand alone 3750x switch configuration, can the secondary power supply only act as a redundant power supply (active/standby), or can it become a "pool" of power similar to power sharing mode for StackPower (somewhat active/active)? I understand there is no stack involved here but I'm curious if this functionality is possible.
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 ?
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.
We are trying to monitor two stacks of CISCO WS-c3750X running IOS 12.2.(58)SE.
We can get the state of the power supplies, but after a power cycle or reboot of the switches the identifier of ONE of the Power supplies ALWAYS change. The OIDs for the rest of the PS do not vary. The problem happens in the two stacks.
We have 3750-X's with dual power supplies. When one of them is disconnected the NMS/Netcool is not picking up the trap. What MIB is needed to monitor the power supplies?
Assuming the power on/off button is OFF on a new secondary power supply - would there be a problem with adding a second power supply to a running 7206VXR while live?
I just purchased the Cisco Small Business Wireless-N Gigabit Security Router with VPN (WRVS4400N). I'm moving overseas (to Israel) and noticed that the power supply does not go up to 240V. I then called the Cisco Customer Support and they told me that they don't have another power supply. Although they mentioned that I could probably get the unit in the country I'm going where it would already have the right power supply. Now, what I'm wonder, should I just send this back and figure it out when I get there? Or bring it with the hope of finding the right power supply?
I have a WS-C6509-E (R7000) and am trying to implement some proactive monitoring for environmental alerts. What is the output from a Power Supply failure for the following “sh log” “sh environment alarm”.
I am looking to upgrade my home wifi from a Linksys WRT54G running DD-WRT to something that will handle .11n. I've been looking at the Unifi PoE APs. Their base model support N, but only on 2.4GHz, and only has a 100Mb port. I was concerned about that being a limiting factor. They've recently released a new line that supports Dual Band and has a Gig port, but it cost about 4 times as much. Here are my goals:
1.) PoE if possible. Currently the AP is my rack in the basement. I'l thinking of running an additional cable to somewhere central on the first floor and putting the AP there for better coverage/signal. Running just a CAT 5e cable is much easier than having to supply power as well. Second thought was to get two Unifi APs and setup a mesh with roaming, which it looks like they support, for best coverage. In that case I'd put one in a top floor room that already has CAT 5e.
2.) I'd really prefer access points to a router. I already have a pfsense box that does the routing. If this means getting something that will run DD-WRT, Tomato, or the like and turning it into an AP fine.
3.) I would like something that is dual band .11n.
4.) Something that support RADIUS
5.) Multiple SSID support and VLAN support. I want to be able to offer at least 2 separate networks.
So am I stuck buying the Unifi dual band AP? Or should I get something like the Asus RT-N66U and put Tomato on it?Does anyone have acutal expreience with the Unifi products?

I would like to ask if how can we determine by mear physical inspection if the power supply of a CISCO2911/K9 router is AC, POE or DC? Do we have images of the actual spare power supply?
Sup720 setup, possibly upgrading to Sup32's in a few years, Right now for power supplies, I am using 2 WS-CAC-2500W ,But I have to run the supplies in combined mode to get all of the cards online.What power supply should I be looking to purchase for this chassis ?
I have a Cisco 7206-CH router and the power supply have been stopped working. I am very confused if the new " PWR-7200-ACE= " power supply can be used with this model which have been announced as end of sale and support from 2007.
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)?
clarify whether this statement found after table 4 of the Cisco 819 4G router data sheet truly means that there will be a power supply to support 48VDC in Q1 of 2013? Here is the statement:
"* Future external reference for 24V, 52V, and 72V DC for railway applications Q1CY2013"
Here is the data sheet source:

I would want to power this router from a -48VDC plant, which is common at remote telecom sites.
Looking at the specs for the 3750 power supply - is the WS-C3750X-48P-S model with the 715W power supply referring to the amount for both power supplies per switch or just one power supply per switch? Meaning, is the 715 a accumulative number or, just the watts of one power supply. I would like to purchase a 3750x PoE switch with redundant power supplies. If this model is not the correct one?give me the model that offers 48 port PoE with redundant power supplies?
power supply problem...?Switch cisco WS-C3750-24P is showing "Unavail" from sh env all.Switch3750#sh env all FAN is OK,TEMPERATURE is OK,SW PID,Serial# Status Sys Pwr PoE Pwr Watts,Does it means that power supply 1 was removed? failed?,Do you know about another command to see more details?
I would like to check if it may be possible to hot-upgrade/swap the 4506E power supplies? Based on the configuration guide; I have summarized the steps as follows:
1. Switch has 2 existing power supplies to be upgraded
2. Remove right side/bay 2 power supply and install new power supply
3. At this point; the new power supply will be in err-disabled due to different power supplies on the switch
4. Remove the left side power supply and install new power supply
For item 4; during the removal of the old power supply in bay 1/left side and installation of the new power supply; I am wondering if the switch would lose power even though the new power supply is installed in bay 2?
I was wondering if I am able to add a redundant power supply to an asr 1001 router that is in production without losing connectivity or causing any diruption to the Users - is it hotswappable?
Is it possible for me to plug in and turn on on-board redundant power supply for a 4402 WLC that is already online and in production without any disruption to Wireless users and APs attached to that same controller?
