The Cisco® CRS-1 Carrier Routing System is the industry's first carrier router offering continuous system operation, unprecedented service flexibility, and system longevity. The Cisco CRS-1 is powered by Cisco IOS® XR Software - a unique self-healing, distributed operating system. As part of a video-enabled, IP Next-Generation Network (NGN), the Cisco CRS-1 Series platform delivers continuous, always-on operation that easily scales to support the massive bandwidth requirements of visual networking experiences such as high-definition IPTV and Cisco TelePresence®. These services demand a platform that delivers predictable forwarding performance and efficient, intelligent, fabric-based multicast replication. The Cisco CRS-1 Series helps enable the Internet and NGNs to handle the approaching zettabyte era of carrier IP communications while protecting network investments for decades to come.
Product Overview
The Cisco CRS Series 42 Port Gigabit Ethernet Interface Module (Figure 1) provides 42 line-rate, IEEE 802.3-compliant Gigabit Ethernet interfaces. Physical interface characteristics can be selected using different modular Small Form-Factor Pluggable (SFP) optics - short, long, extra long, and copper interfaces are supported. Extensive per-port and per-VLAN counters simplify network performance monitoring and troubleshooting.

Features and Benefits
• 42 line-rate Gigabit Ethernet (GE) full duplex interfaces
• Per-port flexibility for interface distance - selected using the appropriate SFP optical or copper modules
• Compatible with all Cisco CRS Series chassis
• Supports in-use insertion and removal without the need to power down the chassis
• Simple configuration, monitoring, and maintenance
Product Specifications

Feature
Description
Chassis compatibility
Compatible with all Cisco CRS-1 and CRS-3 chassis
Requires one of the following forwarding engines (for CRS-1 chassis): CRS-FP40 (on CRS-4/S and CRS-8/S only), CRS-MSC-40G-B (on CRS-4/S, CRS-8/S, CRS-16/S, and CRS Multi-chassis)
Software compatibility
Cisco IOS XR Software Release 3.8.1 or later for CRS-1
Cisco IOS XR Software Release 4.0.0 or later for CRS-3
Port density
Forty-two ports of Gigabit Ethernet per card, each using SFP physical interfaces
Source and destination MAC accounting and VLAN accounting
Autonegotiation
Full-duplex operation
802.1Q VLAN termination
Per-port byte and packet counters for policy drops; oversubscription drops; cyclic redundancy check (CRC) error drops; packet sizes; and unicast, multicast, and broadcast packets
Per-VLAN byte and packet counters for policy drops, oversubscription drops, and unicast, multicast, and broadcast packets
Per-port byte counters for good bytes and dropped bytes
LED indicators
Shared port adaptor (SPA) status: Bicolor green and amber LEDs encode the SPA status as follows:
• LED off: SPA is powered off
• LED amber: SPA is powered on and initializing
• LED green: SPA is powered on and operational
In addition to the status LED, the SPAs also have a bicolor, surface-mount, right-angle LED dedicated to each port to indicate port status. The green and amber LEDs encode the port status as follows:
• LED off: Port is not enabled by software
• LED: Port is enabled by software, but there is a problem with the Ethernet link
• LED green: Port is enabled by software, and there is a valid Ethernet link
Reliability and availability
Online insertion and removal (OIR) without affecting system traffic
Occupies one physical layer interface module (PLIM) slot
