Back-Panel LEDs
Figure 4-3 illustrates the 8-port ANH back-panel LEDs for the ISDN, second

Partition
(8 LEDs)
Amber Lights when a specific repeater port (1-8) has been
partitioned due to a disruption in transmission.
Autopartitioning occurs after an excessive number of
consecutive collisions or an excessively long
single-collision signal.
All 8 LEDs flash when you reset the ANH.
Link
(8 LEDs)
Green Lights to indicate that a repeater port registers a
connection; that is, the port is currently connected to
another powered 10BASE-T port.
All 8 LEDs flash when you reset the ANH.
