Link Speed LED
Located on each of the XSCF-LAN ports, the Link Speed LED is a LAN LED that lights up
in green. The Link Speed LED is turned on when a 100-Mbps LAN connection is
established, and it is not turned on when a 10-Mbps LAN connection is established.
ACT LED
Located on each of the XSCF-LAN ports, the ACT LED is a LAN LED that lights up in
green. When the communication state is Link up, the ACT LED lights up. When the
communication state is Link down, the ACT LED light is off. The ACT LED light is off
while data is being sent/received though the associated LAN connection. So, the ACT LED
looks as if it is blinking.
UPC Port
There are two UPC ports. These ports are a connection between the XSCF Unit and the UPS.
The UPC port is used only when a UPS is connected. For details on the connectors, see the
Service Manual for your server.
