  4. Service Provider HW Status Foundry Networks Proprietary and Confidential

  5. Enterprise HW - Mucho Grande • Completed demonstration of L2 switching code and HW on 12/31 • 2 blades + Management + Switch fabric • Same demo will be used for • Goal this week is to run full mesh of all 8 blades • 1 port on 8 blades run simultaneously before Jan 1 • 32 ports on all 8 blades • Production version chassis in house • ASIC respins • Metal-only respin – changes to die • Cost = $110K per ASIC ($220K total for both) • SXB & IBT • Tape out end of January • ASICs in house in mid-March • Will not affect integration activities Foundry Networks Proprietary and Confidential

  6. Issues • JICPAC – Evaluating whether PLL instability in IGC-300/400 is the culprit • Potential cold susceptibility with IGC-300 blades (May be CAM related as well) • PLL bypass rework does appear to eliminate problem in preliminary tests • IGC-400 blades do not appear to experience this failure • Cerner – 3 problems • Crashed management blade – SW believes this to be a HW failure. TAC attempting to reproduce. • Buffer depletion on 48E blade – Blade received last week – TAC attempting to reproduce • periodic packet corruption on 48T blade • Eagle Alliance • Packet corruption in 15K with worst case patterns – appears to be 15K related • M4 Crashes (Cable and Wireless) • Conference call held with IBM today – failed chip passes verification but fails ‘functional’ test at low temperature in a Apple computer • Resolution from IBM will be slow • May be seeing related failures at other customers(Cerner), however, need to get cards back in house Foundry Networks Proprietary and Confidential

  7. Issues Continued • Yield issue with BXGMR4, B8G-A, BXG modules • Associated with mixed speed grade flag RAMs – Samsung + Micron • AVL will be changed to standardize on Micron • Other items • Need to get CM on line with 15K testing • Analyzing whether speed grade binning of SMCs can help improve timing margins in 15K environment • Received timing models from TI for all SMCs – negative hold time margins > 5 ns in some cases • Adding in trace length delays from cards to get composite timing model • This will help us develop a means to ensure that timing margins are met under all cases Foundry Networks Proprietary and Confidential

  8. Personnel • Open requisitions • HW Manager – Service Provider HW (new) • 3 board level designers (new) • 1 diagnostic engineer (replacement for Frank McMurray) Foundry Networks Proprietary and Confidential
