4.2.1 Diagnostics

When restarting, the RS2-4R performs a hardware self-diagnosis.

During operation, an integrated watchdog (monitoring unit) monitors the

function of the software.

4.2.2 Autonegotiation

Autonegotiation is a procedure in which the switch automatically selects the

operating mode of its 10/100 RJ-45 ports. When a connection is set up for

the first time, the switch detects the speed (10 or 100 Mbit/s) and the trans

mission mode of the connected network (half duplex or full duplex). The au-

tomatic setting of the ports eliminates the need for manual intervention on the

part of the user. The autonegotiation function is activated/deactivated by the

web-based management, the user interface or SNMP.

Note: If the autonegotiation function is active for only one of both transmis-

sion partners, data transmission is halfduplex. The transmission partner de-

termines the transmission rate without autonegotiation.
