RJ-45 pin specification 59
RJ-45 pin specification
When connecting the HP ProLiant BL p-class GbE2 Interconnect Switch to a switch, bridge, or hub, an Ethernet cable
is necessary.
The following figure displays the standard RJ-45 receptacle/connector for 10/100 Mb/s and Gigabit over Copper
ports. Table 15 indicates the pin number and wire color assignments for the switch-to-network adapter card
connection, and the Ethernet cable for the switch-to-switch, switch-to-hub, or switch-to-bridge connection. Table 16
provides the same information for the Gigabit over Copper ports.
NOTE:
A cable configured for Gigabit over Copper can also be used on a 10/100-Mb/s connection.
