3.3.1.4 Ethernet Base Channel Extension
This interface provides access to the system's Base Channel network. It supports 1000BaseT
Ethernet and corresponds to port 1 of the on-board Broadcom BCM56502 switch. The
connector location and the connector pinout are given in the following. Two LEDs next to the
connector indicate the Ethernet connection status. The LEDs are labelled "A" (activity) and "L"
(link).
Blade Damage
The RJ-45 connector(s) on the face plate are twisted-pair Ethernet (TPE) or E1/T1/J1 interfaces.
Connecting an E1/T1/J1 line to an Ethernet connector may damage the product.
Make sure that TPE connectors near your working area are clearly marked as network
connectors.
Verify that the length of an electric cable connected to a TPE bushing does not exceed 100
meters.
Make sure the TPE bushing of the system is connected only to safety extra low voltage
circuits (SELV circuits).
If in doubt, ask your system administrator.
