Cisco 10008 Router Features Chapter 1 Cisco 10008 Router Overview Performance routing engine redundancy in the Cisco 10008 router is achieved through an implementation of Enhanced High System Availability (EHSA). This feature lets you configure the chassis for non-redundant operation with one PRE, or for redundant operation with two PREs. In addition to PRE redundancy, SONET/SDH line cards can be configured for 1+1 Automatic Protection Switching (APS) to accommodate failure of either a line card or the transmission facility carrying trunk traffic to upstream equipment. The Cisco 10008 router is designed to scale to unprecedented levels with plans to further increase scalability in future releases. The current release provides support for up to: • 1300 PPP sessions • 4200 Frame Relay sessions • 300 Border Gateway Protocol (BGP) peers For CT3 line cards, this equates to: • 1176 T1 connections per chassis or up to 3900 T1 connections per 7-foot rack. For channelized OC-12 line cards, this equates to: • 2352 T1 connections per chassis or up to 7056 T1 connections per 7-foot rack. Cisco 10008 Router Features The Cisco 10008 router and power subsystem support the following key features: • 19-inch rack mount, 12-inch depth • 21.75-inch height (3 units per 7-foot rack) • Dual -48 VDC or 100 to 240 VAC redundant hot swappable PEMs • 10 slots total, 2 central slots for PREs and 8 interface card slots • Multiple fans in blower module provide redundancy to support single failure, and blower replacement will not interrupt service (within certain time limits) • Brackets for cable management • Alarm relays; minor, major, and critical Cisco 10008 Router Hardware Installation Guide 1-2 OL-0659-13
