01
The J4895A module provides 16 RJ-45 connectors for Cat5 cabling. You can connect each port to a 100 Mbps or
1000 Mbps segment. The ports automatically detect the speed of the network and configure themselves
accordingly. You also can manually configure a port for 100 Mbps or 1000 Mbps. The ports also support
automatic MDI/MDIX crossover.
The pin assignments and the status LEDs are the same as the ones for the 100 and 1000 Mbps ports on other HP
modules. See Table B.3 on page B-3.

RJ-45 Interfaces
Each port on the J4881A module has its own RJ-45 connector. Each connector supports a 10/100 Ethernet
network segment on Category 5 (Cat5) wire.
• Use a crossover cable to connect to another Routing Switch. A crossover cable swaps the wires so that the
send signal on one port connects to the receive signal on the other port, and so on.
• Use a straight-through cable to connect to an end station or server. A straight-through cable does not swap
the wires.
Figure B.4 shows the pin assignments and signalling for crossover connections on the 10/100 ports.
