Management
Simple Network Management Protocol (SNMP) is supported by the AT-3675.
The bridge can be monitored and manipulated by many SNMP-compatible
management stations. Since it supports the second version of the
Management Information Base (MIB-II) and Bridge MIB, parameters of the
AT-3675 can be managed under SNMP including custom filtering, static
forwarding entries and STP.
Physical Description
The AT-3675 bridge is housed in the slim-line chassis. All network
attachments, the power connector and status indicators are located on the
front panel. See Figure 1.
Media selection for the bridge’s A and B channels are controlled by jumper
blocks on the main board inside the chassis.
There are three pairs of indicators on the AT-3675 front panel. Two pairs
indicate network activity for Channels A and B. The third pair of indicators is
System Power and Diagnostics. The names of the indicators and their
functions are described in Table 1.
Table 1: AT-3675 Front Panel Indicators
The two 10BASE2 network connectors are standard Bayonet Nut Couples
(BNCs). The two 10BASE5 network connectors are standard Attachment
Unit Interfaces (AUIs) and accept standard 10BASE2, fiber optic
(10BASE-FL, FOIRL), 10BASE-T transceivers and 10BASE5 drop cables.
Since the AT-3675 bridge has the same dimensions as the AT-3600 Series
Repeaters, it may be mounted in an ATI rackmount or desktop chassis.
