Default password for a Cisco SG200-26? cisco, cisco do not work .. ??


I had the same issue after what I thought was a succesful reset. It turns out I hadn't reset the switch completely. There is a reset pin hole next to the power switch. Hold it in with a paper clip for at least 30 seconds. ( I was holding in the power button for 30 seconds.)Then you can use the cisco admin and cisco for password defaults. Hope this helps someone in the future since I spent WAY TOO MUCH TIME on it :)

I am trying to add an additional PoE device, put it will not power up. How can I tell the switch to power up a specific port, or put the switch into automatic mode?


Are you within the power budget?

Power feeding of Ethernet is limited for fixed 10BASE-T/100BASE-TX ports. The solution can provide maximum output power per PoE port up to 15.4W on 12 ports or 7.5W on 24 ports simultaneously. The Switch provides independent overload and short-circuit protection for each port, LED indicators for power status per PoE port, and supports IEEE802.3af MIB for Power over Ethernet functionality.
For each attached 802.3af-compliant device, the Switch automatically senses the load and dynamically supplies the required power. The Switch delivers power to a device using the two data wire pairs in the twisted-pair cable. Each port can provide up to 15.4W of power at the standard -48 VDC voltage.

No wireless connection for laptop. Linksys router - model #wrt160n v2


you can run a direct line to that router and go to the cisco web site and get the information you need to run that router. its a pdf format and is 2.56 Meg. Try this

SecureEasySetup (Orange/White) The Cisco logo is the Router's SecureEasySetup button. It

lights up and will stay orange when the Router is powered on. The color orange indicates that

the Router is not using the SecureEasySetup feature, while the color white indicates that the

Router is using the SecureEasySetup feature. When the Router enters SecureEasySetup

mode, the Cisco logo will turn white and start flashing. After the Router has generated

the SSID and WPA Personal key, the Cisco logo will stop flashing and stay white.

To clear the SSID and WPA Personal key, press and hold down the Cisco logo for five seconds.

The Cisco logo will flash slowly as the Router resets itself. The Cisco logo will turn orange to

indicate a successful reset.NOTE: SecureEasySetup is a feature that makes

it easy to set up your wireless network. If you have SecureEasySetup devices, run the Router's

Setup Wizard CD-ROM and follow the onscreen instructions to use SecureEasySetup.

Power (Green) The Power LED lights up and will stay on while the Router is powered

on. When the Router goes through its selfdiagnostic mode during every boot-up, this

LED will flash. When the diagnostic is complete, the LED will be solidly lit.

DMZ (Green) The DMZ LED indicates when the DMZ function is being used. This LED will

remain lit as long as DMZ is enabled. WLAN (Green) The WLAN LED lights up when

the wireless feature is enabled. If the LED is flashing, the Router is actively sending or

receiving data over the network. 1, 2, 3, 4 (Green) These numbered LEDs, corresponding with the numbered ports on the Router's back panel, serve two purposes. If the LED is continuously lit, the Router is successfully connected to a device through that port. A flashing LED indicates network activity over that port.

Internet (Green) The Internet LED lights up when there is a connection made through the

Internet port. A flashing LED indicates network activity over the Internet port.

Good luck
