See the “PRP Ethernet Connections” section on page 2-26 for additional
information about the Ethernet ports.
Note RJ-45 cables are not available from Cisco Systems; they are available from
outside commercial cable vendors. Use cables that comply with EIA/TIA-568
standards.
Caution Ethernet ports are primarily used as a Telnet port into the Cisco XR 12410 router,
and for booting or accessing Cisco software images over a network to which an
Ethernet port is directly connected. Cisco Express Forwarding (CEF) functions
are switched off by default for security reasons. We strongly caution you to
consider the security implications of switching on CEF routing functions on these
ports.
Use the following procedure to connect an Ethernet cable to the PRP RJ-45
Ethernet receptacle:
Step 1 Plug the cable directly into the RJ-45 receptacle.
Step 2 Connect the network end of your RJ-45 cable to a switch, hub, repeater, DTE, or
other external equipment.
Note The Ethernet interfaces on the PRP are endstation devices only, not
repeaters.
