• Interesting Points of Note– Zone 2 fabric interface is dual star topology only.
• Dual-dual star and full mesh topologies are not supported.• Backplane supports only 2 of the 4 available fabric interfaces
on ATCA-717.– Backplane hardwires SAM-A to Hub-A and SAM-B to
Hub-B.• A SAM failover will necessitate a Hub failover, and vice-versa.• Our shelf as populated can’t recover from a SAM failure.
– May not be able to populate all 4 PMC slots on ATCA-717.
• Likely to violate maximum power consumption limit.• With HDD installed, may result in over heating.
– A faulty FTM should be replaced within 1 minute.

Current Status
• Network connections established for switch blade and shelf managers on accelerator controls subnet.– Due to security restrictions these connections are
located behind a Kerberized gateway.– Coordinating with MISCOMP to define Active/Standby
blade pairs as “Clusters”. • HDD on F101 failure.
– Manifested after <1 week continuous operation.– As part of recovery investigation, acquired the software
image and exercised the installation process.• F101 returned to Motorola for repair.
– Status is New, urgency is Minor.– No update expected before 17 October.

Current Status
• Digitizer board layout in progress.– Higher priority activities frequently preempt
progress. – Expect to complete end of October.– Fabrication and burn-in tests to follow.
• First working prototype expected January 2008.
