end node with a fixed duplex mode of full-duplex to a management card port, you should use the AT-S70 management software to disable Auto-Negotiation on the port and set the port speed and duplex mode manually.

For 10 Mbps operation, Category 3 or better, 100 Ohm shielded or unshielded, twisted pair cabling is required. For 100 Mbps operation, Category 5 or Enhanced Category 5 (5E), 100 Ohm shielded or unshielded, twisted pair cabling is required.

The recessed CPU RESET button allows you to reset only the management card. You may need to reset the management card after upgrading the firmware or after you have made a configuration change that requires resetting the module to activate the change.

Note

This reset button does not reset the line cards and/or the module installed in the expansion slot at the rear of the chassis.
