3.3.1.2 Ethernet Management Interface
The blade provides an Ethernet interface at its face plate which is intended for management
purposes. It provides access to port 1 of the Ethernet controller integrated in the MPC8548E
PowerQUICC III CPU. The following figure shows the location and the pinout of this connector.
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.
