Cisco Switches :: SG 200-08 All LED Lights Flashing Green After Power Failure
May 5, 2012Thinking 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.

View 1 Replies View RelatedCisco Wireless :: Strange Power Failure With AIR-AP1231G
Mar 25, 2012I'm having the following issue with a couple of 1231's.
Some overall config info first:
This is a small office with 2x Catalyst 2950 (24-port, no PoE) switches and 4 AP1231G (autonomous). The APs get PoE from a PWRINJ3 each. The injectors are powered by the AP power supplies. Injectors and power supplies are mounted in the patch closet.
The 2 switches are connected together over 4 ports (20-23 on each switch), these ports are set to 1Q Trunk mode.
The APs are connected to the switches, 2 to each switch, on port 1-2. These ports again are configured as 1Q Trunk.
APs are connected to the switch as follows:
[switch] <- patch cable-> [injector] <- patch cable -> [patch panel] <- static cabling -> [outlet] <- patch cable -> [AP]
All this has been working without problems for a number of years.
A few weeks back, AP2 did not restart after a power cut (everything else did). All LEDs are off, port on switch has no LEDs lit. I did not get around to investigating this furtehr until last week. I unmounted (failed) AP2, took it to the spot where (working) AP3 hangs, and plugged it to the cable of AP3. AP2 came to life immediately. I unplugged it and plugged AP3 back in, which restarted immediately.
So I suspect a power supply issue on AP2. I took the injector and power supply that fed AP2 out of the patch closet. When connecting AP2 directly to the power supply, it came to life immediately. So I figure the injector is defective.
On the same day, I notice AP4 is also dead (again all LEDs off, no idea how long, could have been that day or could have been a few days - it has definitely been working after the power cut that appeared to have killed AP2).
So I order 2 new PWRINJ3s and for good measure 2 new power supplies. Later that day, I took the injector and power supply that fed AP4 out of the patch closet. When I try this combination (AP4, injector4 and P/S4), and connect it to a different wall outlet (and therefore a different port -16 - on the switch) IT WORKS! Should have triggered questions, but did not immediately.
Last Thursday I got the new injectors and power supplies. So I take one of each, hook them upto AP2 at my desk, and AP2 starts up. So I mount new injector2 and new P/S2 in the patch closet, put AP2 back in its place, connect all the cables - NOTHING. AP2 does not start. The "power" LED on the injecvtor lights up green, the "device status" LED remains off. I take AP2, new injector2 and new P/S2 to my desk, hook them upto a wall outlet (connected to switch port 17). AP2 starts immediately.
Meanwhile AP3 has (also) stopped working (no LEDs on at all). As far as I can tell, it stopped working after I briefly disconnected (and reconnected) the patch cable between injector3 and the patch panel in the patch closet. The LEDs on switch port 1 are off.
I have since tried to power cycle both switches (took power off both, waited a while, poewerd both back on). No change.
PS: the APs ran firmware 12.3(8)-JA until recently. AP1, AP3 and AP4 were upgraded to 12.3(8)-JEE after the the power cut that took AP2 out. THis is when I found out AP2 was dead. AP2 was still on 12.3(8)-JA. It was upgraded to 12.3(8)-JEE last week when it was on direct power on my desk.

Aug 1, 2011It seems there's no way to reboot this device from the browser interface. You have to actually go and recycle the power by physically pressing the button.Plus, to setup Port Forwarding you have to reboot the modem.This is a major problem because it means you have to be on the premises to change things like the port forwarding. You setup it up, but have to reboot for it to take effect.

Dell :: Dimension E510XP - After Power Failure No Wired Connectivity
Dec 17, 2011After a recent power outage while my PC was in sleep mode, I don't have wired (Ethernet) connectivity.
I have new Dimension E510XP Media Center Edition, Version 2002, SP3 ver had an issue with wired connectivity on this PC after coming out of sleep mode. Of course, the power failure was unusual.
Observations:
- ipconfig /all shows that I have an IP address
- I can ping the DHCP server listed in ipconfig /all and I also can ping google.com.
- I was going to go a restore point set before the power outage. But, somehow system restore had gotten turned off. Oh, well. I did go ahead and turn system restore back on.
Things I've already tried that did not solve the issue:
- Reboot
- Uninstall/reinstall the network adapter driver. Device Manager says the network adapter card is working properly.
- Looked for an updated network adapter driver on Dell's website. Turns out that I have the latest driver already.
- Followed many of the steps from Microsoft at [URL]
- Checked McAfee Security Center firewall permissions list to see if something got changed. Everything looked okay. Also disabled the firewall just to be sure,
- Disabled SafeEyes internet filter.
- Reset the router. Also swapped router ports with a known good PC. The known good PC still had connectivity, the affected PC (the E510) did not.

Jun 20, 2012My company uses the SG 300-10 and SF 300-08 switches to deliver services to our customers. We have been using the upgraded firmware version 1.1.2.0. Our normal procedure is to configure the switches in house and upgrade the firmware before sending them out to the customers. The configurations are confirmed in house after the new firmware has been loaded. Recently we have had several of these switches lose the Vlan configuration that we setup. These incidents have occurred after power outages and scheduled reboots. We do not generally have to reboot our customer switches.
View 11 Replies View RelatedCisco Switches :: SG200-50 Could Not Connect After UPS Failure
Jan 9, 2013I have an issue with the Cisco SG200-50p and almost all of the POE ports on the switch.
We had an issue with the UPS in the server rack yesterday where the UPS failed and turned off all power to the equipment in the rack. It is possible that something was blown in the UPS itself. I was able to reroute power to all devices but the only one that seems to have an issue is the SG200-50p switch. After the power was restored the unit refuses to acknowledge all the IP phones plugged into the POE ports. Running a copper test via the web interface on the majority of the POE ports are listed as Operational Status: Down.
I have tested the affected ports with Laptops, other switches, and simple loop test to verify that the port operational status after a coper test goes back to 'Up' when any of these devices are connected to the those ports. However it fails to recognize when one of the IP phones are connected at all. There are not even any lights on the device for those ports and the status is listed as 'Down' when I plug in any of the IP phones. The IP phone is a Linksys IP Phone SPA922. I know the phones are good because when I connect them through another POE switch they come on and function properly.

Nov 15, 2011We have 3 sf-300 series switches in Layer3 mode deployed in different offices. We have found that approximately every 2-3 months at all 3 locations users experience a serious reduction in bandwidth. Only after rebooting the cisco does the problem go away and we're okay for another few months. some setting/feature that may be contributing to this? We are only using several ports and 1 static route on each switch. We are not using any of the bells and whistles on the switch. 2 of the switches are using the original firmware, whereas the other is using the newest firmware. Maybe this is just what we should expect from a Small Business switch?
View 18 Replies View RelatedCisco Switches :: VLAN Membership Lost After Reboot SG300-20
Aug 31, 2012I have two Cisco SG300-20 switches. Both of them are configured in L3 mode. They have several VLAN's configured.
When I reboot my switches some VLAN membership settings are lost! I have already saved the settings over and over before rebooting, and even tried to save it to the backup memory and so on. Say for example I have changed port 9 to 14 from VLAN 101 to VLAN 105. I save the configuration, reboot the switch. And then the changes are lost. This is a big problem, because servers and my iSCSI network loose connectivity. They already have the latest firmware. This issue was there three firmwares before.
This issue pop-ups when I have a power loss, or I need to reboot/shutdown them manually. It may be off-topic but I also have the feeling that the performance of the switches goes down during uptime. A reboot solves the performance issue. I don't have a performance benchmark, but I can notice it on the performance transfer rate between clients and servers.

Cisco Switches :: SG300-52 Continuous Reboot After TCP Congestion Avoidance Engaged
Mar 12, 2012I have an SG300-52 gigabit switch that has been constantly rebooting and is effectively unusable.This started after Enabling TCP Congestion Avoidance, specifically:
-Turned on TCP CA
-Saved Running Config -> Startup Config
-Rebooted Switch
Since then the switch has been rebooting roughly every half a minute, and the management (HTTP) interface is inaccessible. In addition the factory reset (i.e. reset button for greater than 10 seconds) does not make a difference. I suspect that there is some bug with TCP CA that causes the switch to fail to start up, and that factory reset has failed to clear the startup config.
