between the PC/workstation and LAN, the XSCF-LAN ports are used with the XSCF
Shell and XSCF Web by system administrators or FEs to configure the system
settings, display the system status, and perform component replacement tasks. For
details on using the LAN ports, see Section 1.3, "Types of Connection to XSCF" on
page 1-15 and Chapter 3.
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.
