You're rts/cmos battery has died. You need to have it replaced or this will keep on happening.

What I was told through the mfg. was:
pins 1,8 =NC
pins 2,7= Chassis Ground
Pin 3= TX-
Pin 4= TX+
Pin 5= RX-
Pin 6= RX+

This would actually be a RJ45 (8pin) but uses the 6 pin cable and only 4 com wires.
Evidentally there is no standard for the pin usages for serial communications with RJ connectors. So this information might not be valid for other equipment.

"Forgot email" option, you will have to answer security questions.

You didn't give a model number, so here is a manual for a 3 Com Baseline switch.http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c02581571/c02581571.pdf

Google model number for manual,but no driver for such devices needed to work out

Please check the connections and the settings. Check on the cables, teh connecting links. Refer to the manual for the settings required. Also check with the provider for the default settings.

Hi

You do not say which operating system you use.

Press and hold the Router's Reset Button (sometimes you need a pen to push a Press Plate) at the rear of the Router.

This can be used to Restore the Router to Factory Settings, set the Router back to Default Username and Password (2-5 seconds) or, sometimes, clear the Username and Password for you to enter new ones (usually15-20 seconds), depending on how long you Press and Hold the Reset Button.

Alternatively:

Windows XP
Start > Run >ipconfig.exe > Enter, will reveal the IP Address of the router.

Windows Vista:
Start > type "command" in search box at bottom of Start Menu > click "Command Prompt" at top of Start Menu > type "ipconfig" after the C: \>

Windows 7:
Start > type "cmd" in the search box at bottom of Start Menu > click "cmd" at top of Start Menu > type "ipconfig" after the C:\>

Log onto the internet and type in the IP Address in your browser window and press enter. Access the Router Setup and follow the steps to configure it.

This is probably a stupid way to solve it, but the factors of 84 are 2x2x3x7. 7x2=14 and 3x2=6. 14x6=84.

I don't remember how to work out X x (X+8) = 84 and solve for X.
