My two E3 boxes with 16GB each is feeling kinda cramped for what I want to do, 8GB unregistered ECC is still stupidly expensive, and a dual E5-2620 box with 12 cores/24 threads and 64GB of the much cheaper registered ECC, something like a 560Ti or equiv for playing around with remotefx, and a X540-AT2 or two when they become more widely available really sounds like a lot of fun.
Anyway the only concern I have is adding even more power to the ever growing power bill and heat load what with summer coming. My current setup uses around 320W, what the above system might draw at mostly idle and full load.
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.
Only because we want to updeate A/C system in server room, we need to know what Cisco 2800's the power usage and heat output are. It is on the racks and can't see its spesc.
What is the operating and/or peak power consumption (in kW) of a 5508 WLC with redundant power supplies?
The below power details are from the 5508 datasheet which lists 115 W as the maximum draw (0.115 kW) however this seems a bit low, is this right?
Input power: 100 to 240 VAC; 50/60 Hz; 1.05 A at 110 VAC, 115 W Maximum; 0.523 A at 220 VAC, 115 W Maximum; Test Conditions: Redundant Power Supplies, 40C, Full Traffic. Heat Dissipation: 392 BTU/hour at 110/220 VAC Maximum Cisco 5500 Series Wireless Controllers Data Sheet: [URL]
Is there anyway I can see the power usage on either a 3550 switch and/or 7301 router? I have some far away I wish to see the usage off.
Devices with module power supplies like cat 4500s/6500s/7600 etc all have commands like "show power ...", which will show me input voltage, current and power usage in watts. Is there anything like this for devices without module power supplies?
We are buying some C6509Es with Sup2Ts and 8 port 10G cards. Would like to get a close estimate of the power consumption for our configured chassis. Does C6509E have at least the following components that can share their show power output.

If you had to chose between Dell and another OEM manufacturer for a server to be used in a 1-20 user/employee/computer office network, which OEM would you go for? For a long time I have been recommending/selling Dell servers to my SMB clients (mainly the Poweredge T series) and am pretty comfortable working with these servers. However, I'm also a Lenovo business partner and they seem to have some aggressive pricing. Have any of you used Lenovo servers lately? Pros/cons? Warranty support good? I noticed HP is now selling Microsoft software licenses as a kit when you purchase a server, appearing to be discounted, even if you were to buy the licenses separately through a volume agreement.
Also, being that most of my clients in the 1-20 user/employee/computer office environment are looking at their bottom line, how would you configure a new server to run Microsoft SBS 2008 (some using Exchange, others not yet but may in future)? RAID1/5/10? 8GB RAM enough? Intel Xeon E5600 series processor? SATA or SAS drives?
Here is what I would normally build out a server from Dell: single Intel Xeon E5620 processor 8GB RAM PERC RAID card configured in RAID1 500GB SATA drives x 2 SBS2008 (I don't have much experience with SBS2011 yet, figured it would be best to let others work out any potential issues first)
I need a L2 switch with dual AC power supply and RJ45 uplink The optin I got was WS-C3560X-48T-L + C3KX-PWR-350WAC , but the problem is with uplink . There is no RJ45 1G uplink , there is only option for SFP uplink The another option was WS-C2960G-48TC-L , but there is no dual AC power supply option a good model ( Dual AC power supply , RJ 45 uplink ports (Gig) , with 48 port 100/1000 UTP)
however recently when i check my internet usage log on my wireless company (Rogers) the usage is totally off from what my bandwidth tracker shows me. So i decide to turn off my wifi and see what happens, there has always been this weird wifi connection appearing whenever my wifi appears, then afterwards when i turn off my wifi the suspicious wifi connections disappear. is this possible that someone is using our wifi? i might just be overreacting but it has brought me to concern that if the usage continues my family will have to end up paying over $30 for extra internet use. it is very frustrating me because when i check my DHCP client table it only shows 3 connection, ethernet - my desktop which is not turned on, 2 wireless connection - my laptop and my sister's laptop.
I would like to make a design with 4 Nexus 5596UP. 2 of them equipped with Layer 3 Expansion Module so they can serve as core layer and the other 2 Nexus used as Layer 2 for aggregation server layer.The 2 Nexus in the core layer will run HSRP and will peer with ISP via BGP for Internet connection The 2 Nexus in the aggregation layer will be configured as layer 2 device and have FEX and switches connected to them.What I am ensure of is how the vpc and port-channel configuration should look like between the 4 nexus. What I was thinking is to run vpc between the 2 Nexus in the aggregation layer and between the 2 Nexus in the core layer. Than I was thinking of connecting each Nexus in the aggragtion layer to both Nexus in the core layer using port-channel and vice-versa.

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".
I keep getting alerts from our WCS stating that our 1252s are drawing low power. Now I am aware that they require enhanced PoE (up to 20W) but as we only have standard PoE in that building we purchased the 1252 series power injectors to go with them.
However, even with the correct power injectors the WCS still reports the draws low power error.
Is this a bug? Running WCS 7.0.172 at the moment.
Forgot to say we are using the PWR-INJ4 and the injector status is enabled and you see the injector MAC address when you drill in to the AP status.
We have two switches of the same model (WS-C3560-48PS-S) that are not providing PoE. I'm trying to remotely determine what the cause of the issue is.
Here is some output.

I have a 6500 chassis with 2 power supplies. At the moment I am using the default configuration:
power-redudancy mode redundant
The problem is that an inserted module is in "power deny" state due too insufficient power.
I know, that It's not a good idea to change into combined mode (loss of redundancy), but my customers requested this anyway.
So I will change to combined mode. So here's the 1 million dollar question: "Which modules will go into power deny, if one of my power supplies fails?"
The 6500 config guide states:
"Power supply is removed withredundancy disabled • System log and syslog messages are generated. • System power is decreased to the power capability of one supply. • If there is not enough power for all previously powered-up modules, some modulesare powered down and marked as power-deny in the show power oper state field."
Well, do you know if there's any way to configure some kind of priority? E.g. I definetly don't want by 10Gig Module or WiSM module to be in power deny. Can i statically make sure, those module will be powered on for sure? Like: "power enable module slot_number" How is this calculated? Or is random?
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.
how to change our wireless setup. Currently, we have 2 Cisco AiroNet 1130 WAP's in the office that go directly into the 2 POE ports on our Cisco ASA 5500. These WAP's have 1 SSID and are using WEP for security. After demonstrating the flaws of WEP to my boss, he has agreed that we should use something more secure and I've suggested WPA. We want visitors to our office to be able to hop on our wireless but on a separate guest SSID with WEP.
I'd like the internal SSID to route to the ASA and take the default route to the internet (it will be our new fiber connection once it's installed in a couple weeks). The default route is whichever connection is working since our ASA 5500 will fail over when it detects an outage.
I'd like the guest SSID to route to the ASA and then go over our existing cable connection. This connection will be our backup once the fiber connection is installed. Since we won't be using it very often, but will be paying for it, I advised that we send all guest wireless traffic over this connection since 50/5 is plenty for guests.
The current SSID (which will be the internal SSID) has no VLAN. We do currently have a few VLANS on our network, one for voice (.42) and one for data (.100) and the default (.0). What device to I create the VLAN on (Cisco 5500?) and how to I setup the WAP? I need very basic instructions to start and I'm also trying to do this without causing downtime if possible.
I've attached a diagram of what it should look like. Red indicates our internal network and Blue indicates the guest network. I can send screenshots as well.
I wanted to ask a question about the diagram I have included. We are bringing up 2 MPLS WAN connections and would like some specifics on the best design. We are using BGP to the providers. From there we have big questions. We can run BGP internal and are licensed to do so on the N5K's. The N5Ks are currently using HSRP for inside LAN clients as default gateway. We want to load balance and provide redundant routes using a dynamic approach. Should we use BGP internal utilizing the connections between the routers? Should we use HSRP on the routers? How best to get the routes to the N5K and should we be considering this?
I run 2 RV042 V1 for home and office with Gateway to Gateway VPN connection with single WAN connection in use. Everything works like a charm!
I was even able to create VPN connection with 2 WAN connection on one Router and 1 WAN connection on another with Smart link failover and VPN Tunel Backup.
I got problem though when i tried more complex connection diagram. [URL]
So basically I now have 2 ISP connections on each point with Static IPs and I'd like VPN Connection to be alive for ALL 4 options automatically with failovers (smart links) And tunel backups but i'm not sure if that's ever possible with my equipment.
We have BSNL Broad Band. We have distributed connection between us. So, We want to know, that How many uses of Internet are Every Member using Such as DownloadingUploading, Etc.
Received this notice from ISP. Does this make sense:We have noticed we are getting a huge number of queries from X.X.X.X and it is showing to be about 98% of the DNS traffic hitting our name servers. It appears that the data consists of reverse lookups to 10.1.0.0 network. It needs to be remediated as soon as possible because it could cause a service interruption.It almost seems as if my router is acting as a DNS server. The isp data consists of reverse lookups to 10.1.0.0 network which would be the internal.
On my home network I have 11 devices connected.Is there a way I can give each device a certain bandwidth limit so my Internet doesn't keep getting sucked up?
I recently made a fresh install of LMS 4.1 and added all of our devices (about 400 devices). After configuring all jobs and services everything ran fine.After a few days a guy from the server team called me and told me that the CPU-usage increased over the days. I made some investigations and found out which process is using CPU ressources. Whenever ANIServer is running and collecting data CPU is running at approx. 100%. First it takes only a few minutes to complete but after some cycles ist takes more and more time to complete, after a week it takes more than 4 hours. After restarting ANIServer process it takes again a few minutes and then the duration increases.
Server specs:

i keep getting messages from AVG saying they have detected a very high internet usage, first it was with google and then with firefox..they recommended to shut down and restart..anyone could explain what's going on? I'm not downloadin anything..just checking my mail!
When a physical switchport/routed port has high usage, you can move the link to a higher capacity port, upgrade the port, bond links, etc. What exactly do you do when an SVI has high usage? I guess you could remove some servers from the VLAN, but that doesn't seem like a reasonable solution. What dictates the capacity of an SVI? The backplane of the switch?
Recently got a mobile broadband dongle for my laptop, shows 7.2 Mbps speed in the status window and under activity the received bytes is shooting up, as I write this is has went from 25,000,000 to 35,000,000, that's about 10 mg for a few seconds, it does this even when I have no page open, I can't see anything in task manager, I don't know why it's downloading so fast when there's nothing there, also because of this it is slowing my browsing down,
