6. NORTEL NETWORKS CONFIDENTIAL BayStack 470-48T Switch, Presentation - 5 Distributed MultiLink Trunking Passport 8600 Switch Server MultiLink Trunking Provides High Bandwidth and Fault Tolerance Stack connections to servers and the network center is protected, even if one switch should fail (Distributed MultiLink Trunking) Load-balancing, fail-over protection for uninterrupted access to servers or network center

7. NORTEL NETWORKS CONFIDENTIAL BayStack 470-48T Switch, Presentation - 6 SMLT (Split MultiLink Trunking) Split Multi-Link Trunking –A Fresh approach to the spanning tree problem –Current network rules mean that one connection must be blocked. –Both Links are active Advantages –Fail-over reduced to <1sec –None wasted - You can use what you pay for! IST Core Passport 8600 BayStack 470-48T IST: Inter Switch Trunk

8. NORTEL NETWORKS CONFIDENTIAL BayStack 470-48T Switch, Presentation - 7 BayStack 470-48T Policy Switch Value Proposition High-density desktop switching –Up to 384 ports in a stack of 8 switches Simpler, quicker, more cost-effective stacking –Built-in stacking ports mean no cascade modules needed –Only ones in industry to eliminate cascade module 2 Built-in GBIC slots for uplink ports –Double the uplink bandwidth due to dedicated use –No compromise on using uplink ports for stacking –Up to 16 GBIC ports in one stack – highest in the industry QoS-enabled for mission-critical users, applications, or devices* –Supports L2/L3/L4 packet classification & prioritization *Feature released with v2.2.1.

Uplink

10. NORTEL NETWORKS CONFIDENTIAL BayStack 470-48T Switch, Presentation - 9 Typical Competitor’s Implementation Need to sacrifice 1 GBIC port per switch for stacking Trunking is not allowed across different switches in a stack Hence uplink to the core is limited to only 1 GBIC for the whole stack Single-point-of-failure as only one uplink connection is available to the core Uplink to the Core Switch Uplink Bandwidth Limited to 1 Gbps (Half-duplex).

11. NORTEL NETWORKS CONFIDENTIAL BayStack 470-48T Switch, Presentation - 10 Distributed MultiLink Trunking (DMLT) DMLT allows trunking across different switches in the stack No single-point-of-failure as multiple uplinks are used Each trunk can have up to 8 Gbps uplink bandwidth (Full- duplex) Up to 4 trunks can be configured using all 16 GBIC ports For higher resiliency, trunks can connect to separate Passport 8600s running SMLT Trunk #1 Up to 16 GBIC ports available with DMLT. Trunk #2 Trunk #3 Trunk #4 Fail-Safe Stacking with Built-in stacking ports To Network Core Switch

12. NORTEL NETWORKS CONFIDENTIAL BayStack 470-48T Switch, Presentation - 11 BayStack 470-48T Switch Value Proposition -continued Redundancy –Fail-safe stackability –Load-balancing and fail-over protection with DMLT & SMLT – Technology innovation –Redundant power & UPS support with BayStack 10 PSU Saves valuable rack space with Compact 1U High design Lowers training and installation costs with common “look and feel”

13. NORTEL NETWORKS CONFIDENTIAL BayStack 470-48T Switch, Presentation - 12 BayStack 470-48T Switch - Fail-safe Stacking Fail-Safe Stackability –Redundant, self-healing cascade stacking design –Unlike other stackable switches, BayStack 470 Switches have no single point of failure (non-matrix) Hot Swappable Switches –48V DC-to-DC converter module must be ordered to connect to BayStack 10 Power Supply System for RPSU Unit 8 Unit 7 Unit 6 Unit 5 Unit 4 Unit 3 Unit 2 Unit 1
