Equipment Reliability Issues

• Joel VanderWerf

RSE Health

• Updated firmware on most EVDO modems
• Since then, they have been reliable
• Still need to do Curtner eventually
• The 2 T1 lines have been good
• The 1 GPRS is OK
• Denso WRMs have been mostly OK
• Replaced WRM power supply at Page Mill
• Sniffers work at Calif. and Page Mill

9
Page Mill

• Packet loss is still a mystery
• Swapped everything
• Cables, WRM, pc104 (fan was bad)?
• Still lose packets on wire to WRM
• Usually 0, but brief spikes to 50
• Sometimes seems to depend on queuing of large
  packets (even a 200 byte signage)?
• Sometimes seems to depend on temperature
• We're still running tests
• It's usable
