The NMM front panel has several LEDs, ports, connectors, and
switches, all used to monitor and maintain network activity and to
enable network management capabilities. Figure 3 shows the
parts of the NMM front panel.

Some earlier models of the 2072 NMM have different DIP Switch
labels. Table 1 gives a summary of the names used on the front
panel and in the documentation.

LEDs on the front panel display the status of the hub, NMM CPU,
and segment traffic (Segment 1 or Segment 2). The LEDs are
divided into five categories:
❏
NMM and segment status (CPU to utilization)
❏
Segment collision percentage
❏
Out-of-band and Setup status
❏
Segment Control (Segment 1 or Segment 2 or
none)
