NIC Connector and Status LEDs
®
The Intel Server Board SE7501BR2 supports two RJ45 connectors, one for the 10/100-Megabit
Fast Ethernet controller (NIC1), and the other for the Gigabit Ethernet controller (NIC2).
NIC1 drives two LEDs on its RJ45 connector. These LEDs indicate link/activity on the LAN and
the speed of operation. This connector is on the right side when looking at the I/O area at the back
of the board. The green LED to the right of the connector indicates a network connection is in
place when it is on and transmit/receive activity when it is blinking. The green LED to the left of
the connector indicates 10 Mbps operation when it is off and100 Mbps operation when it is lit and.
See the following table for an overview.
