CNA-8000 Installation and Configuration
707158-003 6-3
If you wish to use the burned in MAC address you can select the checkbox entitled ‘Use
burned in MAC address’. This is not recommended. Since downstream platforms are
configured for the MAC address of this unit, replacing the board in the CNA-8000 would
require reconfiguration of all downstream units. Any other address entered will be used to
override the burned in address. Traditionally, locally administered Ethernet addresses use
the format 02:00:xx:xx:xx:xx, where ‘x’ can be any valid hex digit.
Note that you can not attach the CNA-8000 to the same Ethernet as the platform you are
replacing (or the same bridged Token Ring) and have them powered on at the same time
if you have duplicate addresses. (If you have a duplicate address situation, the CNA-8000
will stay off the Ethernet.) If you want to conduct tests where the CNA-8000 has the
same address as the platform it is replacing, you must ensure that both platforms are not
powered on and connected to the same network at the same time.
Use Burned in MAC Address: This option allows you to use the unique factory
assigned MAC address when selected. Selecting this option will cause the burned in
address to be displayed and used.
Media Type: This dropdown control allows you to specify which media interface is to
be used. Most of the time you will want to leave the option to Auto Negotiate the correct
interface speed. If you have difficulty making contact with the Ethernet interface
remotely, you may want to assign a speed to the interface to match the switch/hub that
you will be attaching to. Valid options for this parameter are:
 Auto Negotiate
 10 Mbit
 100 Mbit
 1 Gbit
Duplex Mode: This option is used to identify whether the interface will run in Full
Duplex or Half Duplex mode. If the Media Type option is set to Auto Negotiate, you
should not have to configure this option. Set the Media Type to Auto Negotiate whenever
possible.
Response Timer T1 (secs): This option identifies how long the CNA-8000 Ethernet
interface is to wait for an LLC response before declaring a timeout and retransmitting the
request.
Retry Count N2: This option identifies the maximum number of retransmissions that
will be attempted before attempting error recovery.
Inactivity Timer TI: This option identifies how long the CNA-8000 Ethernet interface
will wait between attempts to contact the session partner when there is no session
established.
