I have a problem with a catalyst 3508G XL ...
The problem is as follows:
When I power on the system LED keeps blinking and does nothing.I've tried connecting the cable to the console port, but can not communicate.
I pulled a brand new Cisco 3850 Switch out of the box yesterday. Following the Quick Start Guide, I put in the power module, powered it on, and waited for it to complete POST. Then, I plugged in an Ethernet cable between a laptop and the switch on a port in the front, and went to the web interface at https://10.0.0.1. I got to the Express Setup, and attempted to change the IP address of the switch to an IP on my LAN, along with other options. When clicking submit, it didn't appear to take. Upon refreshing in the Express Setup, the IP config was blank, so I once again configured it. This time clicking submit brought up a message that it was changing the IP address. I waited for it to finish, and when it looked done, I powered the switch off and took it to a different room to hook it up to the LAN for further configuration.
When plugging in the power at that point, the switch starts through the normal light process (System LED blinks green slowly), and then eventually the System LED blinks green very fast and never stops. It doesn't get to the point of having the system loaded and ready to log into. There's no amber lights, just the System LED flashing green fast. On the back, the Power module and all bay lights are green, and the Console light is green, but the Management port light is off.
I've tried using the reset button on the back of the switch two different times to reset it to default configuration, thinking I hosed it somehow, but it never goes past the fast blinking System LED.
I have a peculiar issue with a router whering I get the message in the Show Environment as below.

Does a portable RPS device either from Cisco or another manufacturer exists, that would allow you to move primary power for a switch without causing an outage? I realize that for the Catalyst 3560 for example, you can get an RPS 2300 or 675, but my understanding is that these are made for a more permanent installation, not to mention rather costly.
It looks like the RPS 675 is rather inexpensive after all, especially in the secondary market, but still rather large for toting around.
Command to check system status of ACE 4710 appliace? For example if fan is OK or CPU temperature, or other HW things what could be faulty?
For example now I have system ID button blinking amber bot do not know what is wrong. I just know that there is some faulty.I just used show tech-support command and it does not seems that it include some HW statistics.
WRT54G V4, how can i fix this router that has the power led blinking non stop? i flashed ddwrt to it and the power went out half way through flashing. i cant ping 192.168.1.1

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.

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?
View 1 Replies View RelatedI successfully linked a DIR-655 (A4, FW:1.21) via WPS.
I then updated the DAP-1522 to FW:1.21 from 1.1.
Things looked great. I then moved it upstairs to my home theater.
Plugged it in and got a blinking power light. Completely unresponsive to either linkage or 192.168.0.50.
I have followed everyone advice listed either here or in Amazons reviews. And from my own experience with similar electronics the flashing power LED is indicative of a "brick".
I have initiated a replacement shipment from amazon. Just wanted to see if anyone had seen this before.
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.
View 1 Replies View RelatedI 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.
View 2 Replies View Related i tried to upgrade my BEFSR41 model 4.2 to a newer firmware (FW_BEFSR41v4.3_2.00.4.5_20080603_code.bin) and got a blinking power led. I've tried to power cycle (several times), reset (several times, 30/60 secs), unbrick (several times) and still have flashing power led. My connection to the router looks like:

I'm using an E2500 and the Power LED started blinking this week.From the manual, this means “Flashes slowly during bootup, during firmware upgrades, and druing a Wi-Fi-Protected Setup Connection.” We have a wireless printer (wireless disabled), and a Kindle that does use wireless. All other computers are hard wired. I have not started a Wi-Fi protected setup. The router has been in use since the third week in October, and is more or less OK even though the Power LED is flashing. How do I get the Power LED to stop flashing?

View 2 Replies View RelatedI have a problem with a LinkSys WRT610N router (v1).
I have just bought it used. The problems: I see the power led blinking all the time. I can't connect to 192.168.1.1. I do not notice any effect on the leds when pressing the reset button (I feel a soft click when I do that, but none of the leds seem to realize). The manual states that the led should stop blinking after the "self-diagnostics" ends.
My configuration is DSL connection (by AT&T, phone cable), a Siemens 4100 modem, an ethernet cable into the LinkSys router, then an ethernet cable into a Linux PC. Everything is wired. I see the green light of the LAN connection to my PC, the world blue icon and the USB icon stable on, a shy orange led on in the middle (wireless?) and the power blue led blinking. The PC is configured with DHCP, and I can access both the modem (192.168.0.1) and the internet. The gateway address is the one of the modem (again 192.168.0.1). In summary, the ethernet of the router seems to work, but the router is completely transparent, inaccessible, unconfigurable, apparently unresponsive. Trying to connect to 192.168.1.1 (the supposed default address of the web interface of the router, which is different from the 192.168.0.1 of the modem) I get a timeout error, and I can't ping that address. The modem is configured to handle the PPPoE connection, which I am not sure what it means but the text description suggests in this mode I should be able to access the router, provided that its address is not conflicting with the modem's. If I disconnect the modem from the router, DHCP does not get any address. If I force one, 192.168.1.1 still does not respond to pings.
So Is it normal not to notice any reaction when hitting the reset button? is the object just broken, except that the ethernet subsystem still works?
I have a Thomson TG784 router and i have a problem with it. once i turn on my rouet, and no cables are plugged in, except the power one, the two lights start blinking. The Power and the Ethernet ligh blinking. Once i connect my Ethernet cable and my DSL cable, the light are still blinking with no changes... What should i do?

View 3 Replies View RelatedMy Wireless-G WRT54G router has a blinking power light and the startup software says "Unable to connect to the Router! Check that the Router has been connected to the computer, and that your Ethernet adapter is working." I tried uploading the firmware but I can't get to the router page to update. Is there a known problem or solution here or am I just going to have to find the router page?
View 9 Replies View RelatedSo I recently upgraded from a WRT54GS to a WRT160N v2, all was well and good for about 3 days. Then I would lose my internet connection every 5 minutes or so, it would fix itself by the time I could open up command prompt and start pinging to pin point the problem. I decided I would update the firmware to see if that would fix the issue. Since doing that the power light has been blinking non stop. I've tried restoring it to factory defaults by holding the reset button for 30seconds, turning it off for 2 minutes and back on. That little blue light just keeps flashing. I can't even access the router setting page using 192.168.1.1. My OS is Windows xp x64 sp2, and I have DSL.

View 1 Replies View RelatedI 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.
View 9 Replies View RelatedNo download available and none available via Linksys Live Chat or FTP and having spent the best part of the week trying to find relevant firmware on other forums I decided to come here to get answers to the following questions, hopefully from version 1.0 experienced owners or not.
#1. Can the firmware of version 2.0 and 3.0 be reduced to flash version 1.0?
#2. When diagnosing the blinking power light issue by connecting directly to the router and the network card using "ping -t 192.168.1.xxx" which network address do I use, 192.168.1.1 or 192.168.1.2 to 2xx?
I get a reply using 192.168.1.1 but I'm not sure that works when using the TFTP Utility if it's the wrong address on my Laptop to ping?
I have a Linksys WRT54GS vers 7.2 Router on an iMac OS X Leopard. The other day I was in the middle of downloading an upgrade for the router when Firefox gave me this message: "Firefox can't find the server". I was no longer able to access the internet, and the router's green power light was left flashing. It flashed for over 24 hours. I tried unplugging the router and shutting down the computer, then plugging in the router and turning on the computer. (I don't have a modem.) The light was still flashing. I tried pressing the logo button for 5 seconds. Still flashing. Tried pressing the reset button in the back. Still flashing. 'I can't get on the internet or into the router. Linksys live chat gave me a link to "Upgrading the router’s firmware using the TFTP utility", which involves a download, but I can't download anything because I can't access the internet.
View 8 Replies View RelatedI've seen related to flashing power lights on the router involve fixes via firmware upgrades off a PC.I'm on an iMac os 10.6.7. The WRT54 used to work as a wireless modem a couple of years ago. Tonight, it doesn't. power light blinks. Can't access any webpage interface for the thing. Reset, power down, computer restart, cable modem turn off don't change anything. Is there anything that can be done other than tossing the linksys? If that is the only option, are there wireless routers more suitable for a Mac?
