Operation

This chapter describes the features of the CentreCOM AT-3675 SNMP-

Manageable Learning Bridge and shows the basic operating procedures. It

covers how the bridge can be used to overcome common physical limitations

and how to employ the bridge in such a way that network performance is

improved.

When the power is ﬁrst applied, the green System Power and red Diagnostics

indicators are illuminated. The green network Activity indicators are OFF.

The AT-3675 bridge executes a comprehensive set of diagnostics when the

power is ﬁrst applied. The red diagnostic LED stays ON and the port's

Receive and Transmit indicators ﬂash as the tests are executed. The

Diagnostic indicator turns OFF after successful completion of the tests. If

any tests fail, the Diagnostic indicator remains ON. In the latter case, the

bridge should be returned for service. Refer to the inside back cover for the

ATI location near you.

Under normal operation, the green Activity indicators reﬂect the reception

and transmission of data packets, as summarized in Table 5.
