Cisco 12006 and Cisco 12406 Router Installation and Configuration Guide
OL-11497-03
Cisco 12006 and Cisco 12406 routers have the following key features:
• Route Processor (RP)—Slot 5 (bottom slot) is the recommended slot for the
first RP. When the router is equipped with a redundant RP, it can be installed
in any of the five regular line card slots.
• Line Cards—Up to five OC-192 line cards, four if redundant RPs are
installed. These slots support the online insertion and removal (OIR) feature
so installed cards are hot-swappable: A failed card can be removed and
replaced with the router powered on.
• Clock and Scheduler Cards (CSCs) and Switch Fabric Cards (SFCs)—Two
dedicated hot-swappable slots for CSCs; three dedicated hot-swappable slots
for SFCs.
Note The Cisco 12006 Router uses 2.5-Gbps switch fabric; the
Cisco 12406 Router uses 10-Gbps switch fabric. You cannot mix
2.5-Gbps switch fabric cards and 10-Gbps switch fabric cards in a
chassis. The router will not operate with a mix of switch fabric card
types.
Note When operating your router with a single CSC, the second CSC slot
must have a CSC blank filler (MAS-GSR6-CSCBLNK=) installed to
ensure EMI compliance.
• Two dedicated alarm card slots (for 1+1 redundancy)
• Alarm and Illumination—Alarm and illumination for operating ranges in the
card cage, clock and scheduler card, and switch fabric card bays.
• Two hot-swappable AC-input power supplies or DC-input power entry
modules (PEMs).
Note When operating your router on a single AC-input power supply or
DC-input PEM, the second power module bay must have a blank filler
(MAS-GSR-PWRBLANK=) installed to ensure EMI compliance.
