Ethernet Port B
The 2P2 PMC Carrier Board features an RJ45 port on the Front Panel for 10/100 Base-T
Ethernet connection.
In units where only the Baseboard is present, a single network connection
(Ethernet A) is available through the RJ45 connector. With the addition of a 2P2
PMC Carrier Board, a second network connection (Ethernet B) is available through
the carrier board front panel. Both Ethernet A and B may be active simultaneously.
After attaching the 2P2 PMC Carrier Board to a network, you can verify proper
physical connection by executing the OBP network selftest (
test
net
). This test
will indicate external loopback failure on each of the network interfaces when there
is not a proper physical connection.
Use the following connector to attach to the 2P2 PMC Ethernet port:
