Chapter 1 Product Overview

Product Description

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.
