RP Interfaces Using the RP LEDs
Two types of RPs are available for Cisco 12006 and Cisco 12406 Routers: the
Gigabit Route Processor (GRP) and the Performance Route Processor (PRP).
Each of these route processor types is reviewed in the following sections:
• GRP Interfaces Using the GRP LEDs, page 3-43
• PRP Interfaces Using the PRP LEDs, page 3-44
Note When not explicitly specified, this publication uses the term route processor (RP)
to indicate either the GRP or the PRP.
The RJ-45 port LEDs on the RP indicate the following conditions:
• System and RP status
• Which Flash memory card slot is active
• Which Ethernet connection is in use
• What is occurring on the Ethernet interface
The alphanumeric LED displays indicate a successful RP boot.
