Recovery of front end DAQ bad status following 3am crash of h1lsc0

FRS11528

Dave:

Full details are in the separate alog. It took 90 minutes away from the CDS upgrade time to resolve this. However it was important to have a functioning FEC-DAQ system before continuing with the upgrade

CDS Upgrade Part-II

WP7815

Richard, Fil, Dave:

The remaining task for the CDS upgrade were completed today. The following front ends were upgraded to 8-core V4 computers:

h1lsc0, h1susb123, h1sush2a, h1sush2b, h1sush34, h1sush56

The procedure for each was:

power down computer and remove from rack

remove IRIG-B and IX-Dolphin cards, replace full-height plate with half-height (all except h1lsc0)

install cards into V4 replacement machine

put new computer into rack, connect original network, timing, IX-Dolphin.

Connect new v12 One Stop (OSS) fiber

Replace PS2 KVM cable with USB cable

In CER (Fil) pull OSS to IO Chassis, replace old OSS fiber with new.

Change DHCP to serve new computer's MAC address

Power up IO Chassis and computer, verify cards are seen and models start correctly.

Also h1oaf1 was connected to the Dolphin fabric. A new h1iopoaf1 model was started, but some Dolphin issues were encountered which will be addressed later.

The completes the CDS upgrade, many thanks to Rolf, Keith, Jamie, Richard, Jonathan, Fil, Ed for all the hard work to make it happen.
