Chapter 3 Installing the Router
Connecting PRP Route Processor Cables
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 12000 series
router, and for booting or accessing Cisco IOS 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.
