allows the port to receive signals compliant with 10Base-T standard. Low squelch level allows the port to receive weaker signals, enabling you to have longer distances, but increases the risk of losing packets due to the impulse noise. The maximum distances supported for UTP and STP cabling under different squelch settings are shown in Table 21.

The following management command is used to set the squelch setting for the ports:

SET PORT {slot.port} SQUELCH {normallow}

Note that the modules are shipped from the factory with the squelch level set to normal.

∙Enable/disable link integrity

To connect older equipment, that does not fully comply with the 10Base-T standard, to this module, you may use the following management module command to disable the link integrity:

SET PORT {slot.port} LINK_INTEGRITY {enabledisable}

∙Enable/disable port alert

You may use the following command to enable/disable the sending of port up and down alerts from the individual ports on this module:

SET PORT {slot.port} ALERT_FILTER {enabledisable}

This command may be used to allow you to monitor the status of the crucial ports on your network while the alerts from the other ports are disabled.

∙Enable/Disable remote Diagnostics

The Remote Diagnostics feature allows this module to detect certain unusual failure conditions when used in conjunction with the IBM Fault-Tolerant 10Base-T Transceiver. You can use the following management command to enable/disable remote diagnostics:

SET PORT {slot.port} MODE {remote_diagnosticsnon_remote_diagnostics}

Note

The 10Base-T specification specifies a minimum of 31 collisions prior to partitioning of a port. The 8260 Ethernet 24-Port 10Base-T Module automatically partitions a port when more than 63 collisions are detected on that port. This value cannot be changed by the users.
