When flashing, this green LED indicates that data is being sent out on the
Ethernet interface (MMAC backplane).
RX
When flashing, this yellow LED indicates that data is being received from the
Ethernet interface (MMAC backplane).

network.
POK
When lit, this green LED indicates that the EFDMIM Ethernet port internal
self-test was completed successfully. This self-test is run each time you power
on the unit.
IRM Hub Physical Device View
The Physical Device View for an SNMP or Cabletron Proprietary IRM
containing an SNMP Bridge device is similar to the Physical Device View for
IRM2, IRM3, or IRBM hubs. The only difference is that the top portion of the
IRM Physical Device View displays the MMAC Device Statistics Panel.
MMAC Device Statistics Panel
The MMAC Device Statistics Panel displays Frame Rate and Collision Rate
information for the hub. Each rate is color-coded to correspond to the Multi-
Attribute Line Graph. Figure 2-10 shows an example of an IRM MMAC
Device Statistics Panel.
Three buttons are also available from the MMAC Device Statistics Panel to
change the statistical presentation of the Multi-Attribute Line Graph or the
logical MIM horizontal bar gauges, as follows:
The Log/Lin button toggles between a linear or logarithmic scale
presentation of the graph.
