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.
View 10 RepliesWe have small network with 15 Computers all connected to SRW224G4 . After a power brake our switch dosent "boot" anymore. I see all leds working flashing etc but no network acces, no Serial acces. When i try connecting to serial port and "reset" device the screen is blank.

View 1 Replies View RelatedWhat 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.
Catalyst 6500 Enhanced 9-slot chassis 14RU no PS no Fan Tray1Catalyst 6509-E Chassis Fan Tray1Catalyst 6500 24-port GigE Mod: fabric-enabled with DFC41C6K 8 port 10 Gigabit Ethernet module with DFC4 (Trustsec)1Catalyst 6500 Dist Fwd Card DFC416908 10G baseboard1Cat6500 6000W AC Power Supply2Cat 6500 Sup 2T with 2 x 10GbE and 3 x 1GbE with MSFC5 PFC42Internal 1G Compact Flash2Cat 6k 80G Sys Daughter Board Sup2T PFC42Catalyst 6500 Supervisor Engine 2T Baseboard2Catalyst 6500 2GB memory for Sup2T and Sup2TXL2
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 installed an Aironet 1130AG and utilized a power injector for the power source. I have the settings configured correctly in IOS, but the AP takes about 7 minutes to come on (illuminate LED status lights) once the Ethernet cable is connected. Is this 7 minute power-on delay normal when using POE? I am used to the instanteous "on" that usually comes with Cisco products being connected directly to the AC adapter.

I encountered an issue while trying to boot Catalys WS-C4948-S switch. I power on the switch and I'm able to see the boot messages thourgh serial console cable. But it gets stuck at line "Image text-base: 0x1000000, data-base: ..... ". Also I can enter into rommon mode. I tried to use different kinds of IOS images, tried to boot from tftp but with no luck, the issue is the same.
There are no erros on the screen, it just gets stuck when it enters into IOS, so I don't see the IOS prompt.
I have a couple of Switches Blade 3120, working as active-standby model (HSRP) on a new site deployment. There are other 20 sites more or less, working on the same model, without issues. But in this one, we are seeing a high cpu usage. The traffic going through the platform is 600Mbps (on peaks), and in this case we have 40% of CPU usage. Traffic should be close to 3 Gbps. When we tried to send the whole traffic through the platform, active switch began to drop packets on the majority of interfaces.
When we analyze the CPU usage, there is a special process called "HL3U bkgrd proce" always have the most CPU use, but we do not know what concerns. We do not know if it is caused because there are PBRs configured. It should not matter. How I mentioned, there are other sites working fine and have had always the same PBR number.
What is causing the high usage?. Is there a special debug we could to perform to diagnose the issue?. Also, we have seen a high interrupt CPU usage (9% in this case).

View 17 Replies View RelatedI was trying to configure an SF 300-24 for use in my home and obviously did something dumb. It was working fine. The f/w was updated and I had configured 2 VLANs. VLAN2 was ports 1-6+GE1 for IPTV streaming and VLAN3 was ports 7-24+GE2 and GE3 for the rest of my LAN. I was plugged into GE4 and was configuring the switch with a laptop. GE4 was the only port still on the default VLAN1. I chaged the default VLAN to VLAN3, which forced a reboot and the switch never came back up. Attached is what I see when I connect to the console port: [code]
I can't access to GUI using it's static IP or it's default IP on any port and the console never reaches the point where I can log in. The System light is flashing green but the boot sequence never progresses past what's in the screen shot. I tried to do a hard reset using the recessed button on the front panel but it does not seem to have any effect, no matter how long I hold it down.
I have a 3560x switch with the flash formatted . I have tried to solve the problem by copying the IOS file to the flash. But the boot failed either .I have tried to copy the same IOS by the Xmodem, The boot failed again.My question is how to fixed the boot issues after the flash was formatted?

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.
