Cisco Switches :: SG 200-08 All LED Lights Flashing Green After Power Failure
May 5, 2012
Thinking 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.
There was a problem with one of our servers. We were unable to connect to it remotely. We restarted the server. Still we were unable to communicate with it. Static IP is provided.
In the connections settings, it showed the send and receive as 0. I noticed the network card lights. Both were flashing green in sync, like twice in one second. I removed the cable and funny thing was, it was still blinking non stop in the same way. I plugged the cable back in and took back out, the same result. After a second restart of the server, it started working normally and i was able to communicate with the server.
We have a Cisco SRP 527W router that was not showing up on the LAN. so we tried a Factory Default reset but it seems to be dead.
The power light is flashing constantly,the 4 LAN light are constantly on,the DSL Data light comes on for 1 sec when device is powered up.
i have tried connecting directly to a PC, the NIC reports as network cable unplugged.i have tried the (power on device, hold down reset button, power of after 30 sec, power on after 5 sec, release reset button after 5 sec) but still "network cable unplugged".
the firmware flash utility will not find the NIC the device is connected to.the router is less than a year old, is there a fix or is it a warranty replacement ?
I have a 1 month old SG200-26P - the green status LED is blinking constantly (> 30 minutes), I cannot access the webGUI, nor is it responding to ping. I have tried resetting via holding reset for > 10 seconds with no effect, the status/activity LEDs are still illuminating against all connected ports, excluding any of the PoE ports which are running a couple of cisco IP phones. I've tried accessing the device via both the static IP I configured, and the default IP.
I have disconnected all ports, then powered on the device, but same results...Do I have a dead switch? Anything I can do other than return for warranty claim which is going to be last resort due holiday period and leaving the customer offline for extended period...

We have several SF-300-48P switches, eveytime there is a power failure the switches need to reboot 2 or 3 times before they are able to route packets again.
dcm425 dont turn off also has 4 solid green lights...it happen after a power outage my router works fine but my dmc425 cable modem just has the 4 green solid lights when it's plugged in when i push the power button nothing happens at all
When connected, all lights on modem are green, so is the light on the Time Capsule. When I go to a website, page cannot be displayed. When I insert the ethernet cable directly into the back of the iMac straight from the DSL, the internet works just fine.With all lights green but no internet connection, what am I missing?
Recently we had a situation where our users were unplugging one of our un-mounted 1252 LAPs. They would do this so they could borrow the wire to direct connect any one of their devices not realizing they were disconnecting a wireless access point. After discovering that the AP was unplugged once again, our admin plugged the AP back to the network but noticed that it no longer would connect to the controller. We can no longer console into the AP but can console into all other APs we have. All 3 lights are now green. Radio and Ethernet are solid and Status is blinking. I found the Cisco doc explaining the meaning of the front panel lights but have not found this particular configuration. What these lights mean and why not being able to use the console port?
I am replacing an old Catalyst 3550 (that has 2 Gig ports) with a 3750 (that has 4)- I used the exact same configuration in the new switch. When I plugged in the new 3750, the trunk ports started blinking from green to amber. I dont know why this is occuring- it SEEMS to be fine, but we havent thrown a whole bunch of traffic over it.
I have DSL 8Mbps DL and 768kbps UL,Internet -> Modem -> Cisco Router -> Firewall -> Switch Core - > Multiple switches like sfe2000p,CiscoRouter: i use port gig0/1 for PPPoE and i use port gig0/2 for LAN static,Router port gig0/2 with 122.54.144.153/29 connected directly to Firewall port13 with 122.54.144.154/29,i want 122.54.144.153/29 will my default gateway,Please include no limit bandwidth,filter etc at router, Firewall will be DHCP Server and control the bandwidth, filtering etc and the client computer should get 8Mbps.
My EA4500 is not working. The power indicator light is on but the green and yellow lights on the Internet port are not flashing and the modem the EA4500 is connected to show no activity on that port. Also, the EA4500 is not broadcasting so I can't even connect to it to use Cisco Connect to troubleshoot. I tried resetting it but it did nothing. This has happened before but is usally fixed with a reset.
I bought a new DIR-615 and tried to install dd-wrt on it. During the installation all of a sudden the router stopped blinking the led lights and stopped responding to anything. It's current status is that I can only see globe LED and the other 4 LAN LEDs in continuous green and NOT blinking. The power LED and wireless LED are not even displaying. I tried all kinds of reset like soft,hard and crash but no response. It's not responding to anything except those 5 LED lights.
-no power light -solid green lights: WAN-L1-L2-L3-L4
tried to go to recovery mode (power on while holding reset switch).....does not work.my search on the internet revealed, that after bad flash, power light still comes on, maybe as orange, maybe blinking, or just blinks once
So, I messed around with my router a little too much and just want to restore it back to the original firmware now. I have a WRT54GS v7 Linksys router and tried to follow this guide to flash the firmware to something a little more useful. After step 7 of that guide, I can't ping my router, can't access the GUI, and have no idea what my router's IP is. If I assign each computer plugged into the router an IP like 192.168.1.2 I can ping them, so the router is still functioning somewhat. I'm plugged into my modem right now to get on the Internet.
Right now, my power light is off, my DMZ light is off, my WLAN light is off, but the other lights turn on if I plug a cord into its port (plug a computer into port 1, port 1's light comes on). When I do an ipconfig /all i get this. I doubt the web interface still works, but if I could at least get the router's IP, couldn't I use tftp and put the firmware on that way?
I just bought this Linksys E3000 high performance router and all it does is have the LED Power light flashing constantly. I've tried resetting it and leaving it unplugged for a few hours but nothing works. When I try to use the installation software it gets to 25% then says it couldn't find any network
I came home after a few days vacation to find all the lights blinking on my router. I have tried unplugging and rebooting. Same result. I then bypassed the router and have internet on my main computer so I know it is a router issue. I use the router for my laptop and cell phone. Do I need to figure out how to do a master reset or is the router toast?
i have Linksys WRT610N V2 now i got problem the power light flashing still keep cannot use but wifi and wan and lan no light but 1 light power only still keep power flashing blinking no stable now i using adsl modem direct connected i using linksys am300 adsl modem
I have a WRT300N and the power light is dim and all 4 ports are solid green along with the internet light being solid green.. Nothing else is plugged in.. Just the power.. I have tried to hard reset and nothing happens.
I have been given the task of unbricking a WRVS4400N V2 router. It just sits there with the Power and Diag lights blinking and does nothing else.I'm thinking I'm going to have to try to find some way to flash the firmware, because I'm seeing that this is a common problem with this router.I already tried support "chat" online, but after about 20-30 minutes waiting for someone to actually come into the chat room, I gave up.I did note that this model is not being sold anymore and won't be supported before very long, so this may be a gigantic waste of time, but I thought I would give it a shot.
So I just got this new WRT160Nv2 router. I have (1) wired computer and then my laptop running wireless to it. For the first couple days I had some issues getting consistant internet but after reading some stuff on here I downgraded to the version 8 hardware and it worked GREAT for about 3 days. Now my power light won't stop flashing and I have NO internet connection at all through the router. I have tried to reset the router by holding down the button and also unpluging it but still nothing.
I am on a surge protector and we lost power last night. This morning we were stilling experiencing a brown out but now the power is back 100%. I've walked through the E1000 router reset and not matter what I do, all the lights except the power light blink rapidly and dimly. Could the router be fried even though it's on a surge protector???? It's less than 6 months old so hopefully still covered by warranty.
I can not fix the problem with the router. I power it up, all is GREEN, then it blinks RED, then GREEN, and finally RED. The router is terminally not connected to the Internet. How can I check if the router is BAD. I have done all the troubleshooting, examples:
connected ethernet directly to computer - no problems attempted to fix problems via belkin software changed channels on modem updated firmware etc, etc
I've got the power cut while PC was running (w7). After rebooting I'm not able to connect to the internet anymore.
In Device Manager, under Network Adapters there is a "Realtek PCIe GBE..." device properly installed. But under Other Devices there are now more entries with exclamation mark:
I tried updating the drivers, then deleting and reinstalling but no success so far. Still can't connect to the internet. The browser can see the router, at 192.168.1.1 I don't know where the problem is.
Everything was working fine. Changed Nothing on the router. Goes out and now wont broadcast a wireless signal, cant manually reset the router, or get into the settings with 192.168.1.1
Currently I am wired through it with my desktop and its working, but not much else.
We have cisco wlc 2125 with 13 AP 1131g. All works good. But after power failure one AP can not join to controller, only reset work to recover connection AP to WLC. Additionally, we don't have access to rs-232 port on AP. In this moment on WLC we can see DISCOVERY request from AP and response from WLC to AP, but AP don't send JOIN to controller.
I bougth a used ASA 5505 on ebay which is experiencing this problem [url]... LEVELS or at least the described problem, if i touch the appliance while it is running it will somtimes go to this non working state as well
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”.
