Connecting Cerberus to Computer.

Connecting via Ethernet Port (Ethernet Card)

All Ethernet ports of router are made in the technology, which automatically activates

Crossover if necessary. Thanks to autonegotiation of connection speed the router will

automatically select the maximum available speed rate. Transfer at 10/100 Mbit/s rate

requires the category 5 cable wired with RJ-45 connectors. In case of "straight" cable both

connectors must be crimped in standard EIA/TIA 568B. In case of Crossover cable one

connector must be in standard EIA/TIA 56A, and the second in EIA/TIA 568B. After connecting

the device to one of the ports, corresponding LED will begin to blink. That signals the process

of the auto-checking of port and the negotiation of connection speed rate.

Configure TCP/IP

After connecting the computer to the router the TCP/IP protocol should be configured. The

protocol should be automatically installed together with Network card drivers. It is advised that

TCP/IP should be configured to receive IP address and all the necessary network parameters

from DHCP server automatically. You can find step-by-step configuration for different

Windows systems below.
