Overview
2
Network diagnostics are provided on the front, as shown in Figure 1, and
back of the AT-3012T repeaters to aid in troubleshooting and fault isolation.
On the front of the repeaters, each network segment has two LEDs, packet
“Receive” and “Port OK,” as well as an “Off Line” switch that provides a
manual partitioning capability. In addition, there are three central LEDs
indicating “Activity” “Collision,” and “Power” for the repeater. On the back
panel, the “Link Integrity Test” LED shows continuity of the media
connection to the network node.
The CentreCOM Multiport Repeaters conform to the IEEE 802.3
specifications. This permits a maximum of four repeaters to be “cascaded,”
allowing over a thousand individual segments to be configured into a single
network.
