■ During normal operation, you may notice the Alert LED lighting briefly from time to time. This indicates that the Router has detected a hacker

	attack from the Internet and has prevented it from harming your
	network. You need take no specific action on this, unless you decide
	that these attacks are happening frequently in which case you may
	wish to discuss this with your ISP. The Router logs such attacks, and
	this information is available through the Status and Logs screens.

Power LED or	■ Check that your Router is receiving power by looking at the status of
Power Adapter OK	the Power LED on the front panel and the Power Adapter OK LED on
LED Not Lit	the rear panel:
	■ If both LEDs are lit green then the unit is receiving power.
	■ If both LEDs are unlit then no power is being supplied to the unit.
	Check that the power adapter is plugged into a working mains
	outlet and that the mains outlet is supplying power. If the mains
	socket is supplying power then the power adapter or power
	adapter connection may be faulty. See “Replacement Power
	Adapters” below.
	■ If the Power Adapter OK LED is lit but the Power LED is unlit then
	there may be a fault with your unit. Contact 3Com Technical
	Support.
	■ Check that you are using the correct power adapter for your Router.
	You should only use the power adapter supplied with your Router.

Replacement Power If both the Power Adapter OK LED and Power LED are off, check your Adapters power adapter connection. If the mains outlet is working and is capable

of supplying power to other devices, contact 3Com Technical Support and ask for a replacement power adapter. Please quote the power adapter part number shown on the OfficeConnect power adapter you are using.

Alternatively, quote the part number for your region:
