Repeater Management 3 - 39
DUA1663-0BAA0 3
You can enable or disable the generation of link pulse signals for an
individual port. In an 802.3 10BASE-T compliant network, leave this
option at the default setting. If you are using non-compliant
transceivers that do not use the link pulse signal, you will need to
disable link pulse to enable the network to function correctly.
Alternatively, you can replace non-compliant transceivers with
10BASE-T compliant transceivers, such as the ISOLAN TP Transceiver
(3C16810).
D isabling generation of link pulses also disables detection of link pulses.
In this case, repeater ports will assume that there is a connection and
light the appropriate LEDs, even if there is no connection.
You cannot disable the link pulse for a port that is the main or standby
port of a resilient link pair.
Link State (Read-only) This field shows the connection state of each
port.
Lost Links (Read-only) The number of times the link has been lost
since the Module w as last reset.
Partition State (Read-only) This field shows whether or not the port
has autopartitioned. If it has, check the cabling at both the unit and
any devices connected to that port.
Port Resilience
R esilient Links may be set up ONLY on Hub 10 and FMS II Units.
