Data Sheet
The Cisco ® Interface Flexibility (I-Flex) design combines shared port adapters (SPAs) and SPA interface processors (SIPs), taking advantage of an extensible design that helps enable service prioritization for voice, video, and data services. Enterprise and service provider customers can take advantage of improved slot economics resulting from modular port adapters that are interchangeable across Cisco Systems ® routing platforms. The Cisco I-Flex design maximizes connectivity options and offers superior service intelligence through programmable interface processors that deliver line-rate performance. Cisco I-Flex enhances speed-to-service revenue and provides a rich set of quality-of-service (QoS) features for premium service delivery while effectively reducing the overall cost of ownership. This data sheet contains the specifications for the Cisco 8-port Fast Ethernet SPA (refer to Figure 1).

Product Overview

The Cisco 8-port FE SPA is available on high-end Cisco routing platforms offering the benefits of network scalability with lower initial costs and ease of upgrades. The Cisco SPA/SIP portfolio continues the company's focus on investment protection along with consistent feature support, broad interface availability, and the latest technology. The Cisco SPA/SIP portfolio allows deployment of different interfaces (packet over SONET/SDH [POS], ATM, Ethernet, etc.) on the same interface processor.
Fast Ethernet interfaces are commonly used for interconnecting routers or other devices within a central office or data center or in a metropolitan-area network (MAN). With Fast Ethernet SPAs, users can mix-and-match SPA ports with other types of interfaces in the same slot. Each SPA provides standards-based Fast Ethernet implementation for compatibility and interoperability.


The Cisco Fast Ethernet SPAs can be used in multiple applications, including:

• Inter- and intrapoint of presence (POP) aggregation

• Metro Ethernet

• Internet peering

Key Features and Benefits

The Cisco SPA/SIP portfolio offers many advantages, including:

• Industry's most modular, flexible, intelligent interface processors

– Unmatched flexibility, providing mix-and-match capability of interface types on the same interface processor for consistent services, independent of access technology.

– Pioneering programmable interface processors that provide flexibility for the service diversity required in next-generation networks.

– Innovative design that provides intelligent delivery of services without compromising on performance.

• Increased speed-to-service revenue

– The future proof programmable Cisco architecture extended to 10 Gbps dramatically improves customer density, increasing potential revenue per platform.

– Interface breadth (copper, channelized, POS, ATM, and Ethernet) on a modular interface processor allows service providers to more quickly roll out new services, helping ensure that all customers, large and small, receive consistent, secure, and guaranteed services.

– High-density Small Form-Factor Pluggable (SFP) interfaces are featured for high-port-count applications with reach flexibility. Future optical technology improvements can be adopted using existing SPAs.

• Dramatically improved financials of your routing purchase

– Improved slot economics and increased density reduce capital expenditures (CapEx).

– The ability to easily add new interfaces as they are needed helps enable a "pay-as-you-grow" business model while still offering a high-density solution.

– SPAs are shared across multiple platforms, and can be easily moved from one to another, providing consistent feature support, accelerated product delivery, and a significant reduction in operating expenses (OpEx) through common sparing as service needs change.

Product Specifications

Table 1 provides specifications of the Cisco Fast Ethernet SPA.

Table 1. Product Specifications



Product compatibility

• Cisco 12000 Series Router
• Cisco XR 12000 Series Router

Port density per SPA

8 ports of Fast Ethernet

Physical interfaces

RJ-45 with support up to 100 meters Cat-5 UTP or STP cable

LED indicators

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 amber - Port is powered on and initializing
• LED green - Port is enabled by software, and there is a valid Ethernet link
