Optical connection takes ~10 seconds to stabilise due to suspected finisar issue but works otherwise. (Note spare finisar and g-link Tx and Rx available at IC) Returned to SLAC. - Will lab(?) 03/22/07L back at slac, tested ok BURN 03/23/07L doesn't pass TRB tests after burn in on any channels. May be that it dislikes being switched on/off repeatedly. Seems to be okay for running tests on IOBs/ADBs though, so may become the test-stand resident. 04/04/07L Tyson puts on a brand new Transceiver TEST 04/05/07L Passes EmcFeeTest on all channels BURN * LEAVE THIS IN THE TESTSTAND FOR NOW * 04/11/07L There is an indication that this TRB may fail after being on for a while. This locks up TPC when it happens. ** USE THIS ONLY IN THE TESTSTAND *** NOT FIT FOR IR2 *** LAB ONLY ------------------------------------------------------------------------------ 4 blew up somewhere around XILINX; non-EMB part works IC 04/03/00 fixed (this is trigger spare) IC 05/25/00 back at SLAC, with EMT group SLAC 03/25/04 MISSING - wah ????? 09/07/04 PROBABLY IN EMT (TS) ITSELF ------------------------------------------------------------------------------ 5 10/25/01 found in dataflow lab. is this the trigger TRB? 10/26/01 Lab-TS 02/12/02 removed: suspected malfunction lab 02/12/02 OK lab 05/01/02 Lab-TS 10/15/02 dead. lab 12/17/02 to IC for repairs IC ------------------------------------------------------------------------------ 6 09/xx/06 Pulled from BF02 as part of shutdown - jong 11/17/06 Cleaned and tested - ready for service again - tim/jong 01/04/07 pulled: Ch 6 (counting from 1) stops talking to Iob Boxed up and ready for journey to DP 02/20/07 Diagnosed damaged controller chip for channel 6 - replaced. Power surge suppression diodes added. All channels now work. Returned to SLAC - Will lab? 03/20/07L Back in Lab and tests good - thanks! BURN 03/21/07L burnt in and retested - passed all tests READY 03/28/07 Back in service BB1 ------------------------------------------------------------------------------ 7 09/xx/06 Pulled from BF00 as part of shutdown - jong LAB 11/17/06L Cleaned and tested - ready for service again - tim/jong 11/29/07 Reinstalled after the uncabling shutdown BF0 04/10/07 Removed from BF0 as numerous slots were showing dataflow damages and strange even-odd calibration problems. It seemed to behave after powercycling but the problem slowly comes back after some time. LAB ------------------------------------------------------------------------------ 11 xx/xx/xx was at BB1 BB1 08/30/06 pulled from BB1; won't power up, needs testing - jong LAB 11/17/06L failed FeeTest in all channels (LINK A/B NOT READY) Boxed up and ready for journey to DP - jong 02/20/07L Diagnosed blown U34 & U38 chips, replaced. Xilinx chip also damaged - this has been disconnected since not needed Power surge suppression diodes added. Returned to SLAC - Will LAB 03/22/07L tested okay, burnt in, retested okay. READY 07/10/07 reinstalled BF0 ------------------------------------------------------------------------------ 13 IR-2 08/01/02 BF3 08/28/02 suspected malfunction when writing to/reading from IOB/ADB.

Chips replaced, surge suppressor fitted and board tested and returned to SLAC - Will LAB 11/17/06L tests fine - jong Board will go to BF03 READY 11/29/07 reinstalled as part of recabling BF3 ------------------------------------------------------------------------------ 15 xx/xx/xx has been at BF1 09/xx/06 Pulled from BF01 as part of shutdown - jong LAB 11/17/06L Cleaned and tested - ready for service again - tim/jong READY 11/29/07 reinstalled as part of recabling BF1 ------------------------------------------------------------------------------ 16 08/01/02 was in Fwd_3. +5V current was always high (>0.5A) IR-2 more recently even higher (up to 1A). Somewhat correlated with crate 3 TPC-TRB communication problems 08/01/02 not entirely proven that TRB was source of problem IR-2 03/23/04 not ready TPC light when used on TS - wah IR2 03/23/04 on cpo/Ray TS had flink timeouts, possibly related to not ready signal- wah IR2 09/07/04 Returned with Paul to IC - wah IC 10/01/04 Dave P replaced U38, removed Xilinx, +5V current normal. Dave "not sure he fixed it". Wah 10/04/04 Tried in Fwd_3, cosmic run shows no events. Logs have Care Cntl Reg Error a000000 (Read D link start bit missing). Removed. To be tested. Wah lab 11/02/05L Passed all tests - installed on Detector BF3 11/03/05L Seemingly damaged when accessed to re-seat. lab Cannot communicate with IOBs 7,8 & 9 08/08/06L Seems to be working in the test stand - Gagan lab 04/05/07L * TESTSTAND RESIDENT BUT NOW READY FOR ACTION * READY 04/10/07 installed at BF0. EmcFeeTest fails on ch 6 (counting from 0), but all other indications are that it's functioning perfectly. BF0 07/10/07 removed from BF0 as some of the problems that we saw from BF0 before replacing the TRB seems to have come back.... This looks more like the TPC problem. This TRB is probably okay. TEST ------------------------------------------------------------------------------ 17 stops working once it heats up, OK when cold IC 04/03/00 Xilinx draws out-of-spec currents IC 05/28/04 Back from DP - wah lab 10/**/04 Given to Ray/cpo TS Ray TS ------------------------------------------------------------------------------ 18 02/11/00 fixed.
