3 - 20 ONline Ethernet 24-Port 10BASE-T Module Installation Guide
Enabling Link Integrity
Use the following guidelines to determine whether to enable or disable
Link Integrity:
Enable Link Integrity for all ports on the 24-Port Module for networks
that comply with the 10BASE-T standard.
Disable Link Integrity only when connecting to older equipment that
does not comply with the 10BASE-T standard.
The Link Integrity setting at both ends of a connection must be either
enabled or disabled. If Link Integrity settings are not configured to the
same setting, the 24-Port Module with Link Integrity enabled reports a Link
Integrity error.
The Link Status LED for each connector (bank) will be on solid if the Link
Integrity is valid for ports which are both enabled and have Link Integrity
enabled. If all enabled ports have Link Integrity testing disabled the LED is
also on solid. In all other cases the LED will blink in approximately 1-second
intervals.
Note: In an unmanaged concentrator, you can only enable or
disable Link Integrity for each connector on the module.
To enable Link Integrity for a port:
SET PORT {
slot.port
} LINK_INTEGRITY {enable}
{
slot.
all} {disable}
