Before shutdown. 1) Prepare cover or door for M100. Possibly install before shutdown. Should be installed before decommissioning. [Russ?] 2) Do a test run of installing all infrastructure on test racks in DAB3, including pipes, hoses, valves, fans, plenums, etc. Check out RMIs, smoke detectors, etc. Then bundle/box all components for each and every MCH1 rack. [Victor Martinez] 3) Validate/update all mechanical drawings. Verify the vertical positions of all MCH1 infrastructure. Where do we place the L1Cal readout crate? 4) Prepare TAB/GAB crate and strain relief system so that the crate and all cables can be moved as one unit from the sidewalk to MCH1. 5) Obtain/purchase spare ADF crate for use on the sidewalk. 6) Make note of any LVDS cables which may have been damaged during the installation on the sidewalk. We may try to remove these cables after they are disconnected at the sidewalk, but before they are reconnected in MCH1. 7) Do some tests with the Run IIb version of the Calorimeter preamp pulser, so we know this tool works, the documentation is validated and the system is reliable. 8) Have an updated list of any "broken" trigger towers (and why), so we do not waste time on those channels during installation and commissioning. After Calorimeter noise studies, and before decommissioning. 1) Disconnect/turn off/close valves for all power and water to M102-113 for safety reasons. Water valves are at the bottom of the rear of the racks. 2) Rework VESDA, so M100, M101, M122-124 can be powered up independently of the L1Cal racks (M102-113). [Dan Edmunds] 3) Put up sign, and control access to MCH1 throughout the decommissioning and installation. We have to determine if there is a clear path for the DAQ Shifters to do their safety checklist during the shutdown. 4) Make sure there are matching labels to doors and rack frames for M103-112. Remove doors, place any hardware (hinges, screws, bolts) in bags and tape bag to specific doors. Store doors elsewhere (DAB3, pit?) as they are not needed until the end of the shutdown. 5) Locate ECL cable which carries L1Cal signals to the TFW. Dan Edmunds is primary for this job. The cable will be disconnected, and carefully threaded out of M104(?), over cross aisle cable tray to M124(?), and stored for safety. It will be reused (GAB->TFW) after everything else has been installed. 6) Remove all twist-and-flat ribbon cables in M103-112, front, back and on top in cable tray. The preferred method is to snip the ribbon cables at the top of the front and back of the racks. Next, disconnect the connector ends from the electronics, front and back. Finally, pull out all the excess cable from the cable tray on top. All the twist-and-flat ribbon cable goes to scrap. We will need a bring a 'laundry cart' or some similar container to the control room outside the MCH1 door in order to dump the possibly hundreds of pounds of scrap cable. Designate a place to move the cart after it is filled. 7) Disconnect blue/grey signal cables. Do no more than four cables at a time (a row to a single electronics board). Apply new labels (already printed, in cabinet on sidewalk). Do not waste time removing old label, and apply new label so it does not obscure old label. New labels are only applied to the MCH end. It may be necessary to remove cable ties in order to find a straight unused part of the signal cable near the connector end so the label is visible and readable. 8) There are a total of 128 blue/grey cables in each MCH rack. After the new labels are applied, the cables need to be stored in the vertical grey cable guides. This step may also require removing additional cable ties. Use caution, and minimize handling. The old ties will need to be removed eventually in order to dress the cables for the final routing to the patch panels. Do we need some wrap or cover for the connectors? 9) All remaining cables should be scrap. However, we may want to doublecheck with Dan Edmunds at this stage before proceeding with the systematic removal of all other cables and components. 10) Strip racks M103-112 to their frames. We need another portable container in which to dump the scrap electronics boards, and another container for the old power supplies. Who will do this work? Can people work from the front and back of the rack removing different components, or from adjacent racks? 11) Replace water services. New pipes, valves, heat exchangers, etc. 12) Install smoke detectors, rack monitors, RMIs, associated cables. 13) Install AC distribution boxes. Need some restraining mechanism so the power cables are not pulled or pushed accidentally. 14) Checkout water, power and safety services. 15) Install shelves, plenums, blowers and patch panels. 16) Power off all crates on the sidewalk. Make sure all cables to be used in MCH1 are labelled before disconnecting them from any components. 16) Disconnect all signal and power cables to ADF crates on the sidewalk. All four fully populated (ADF cards in front, ATCs in back) ADF crates can be relocated from the sidewalk to M104, M106, M109 and M111. 17) Install the strain relief systems at the rear of the ADF crates. There are two roll bars on each side and about four inches above the ADF backplane for the pleated foil cables. In addition, another roll bar is needed another 4-6 inches higher up and to the side of the ADF crate closest to the TAB/GAB location for the LVDS cables. 18) Disconnect all cables to the Communications crate on sidewalk. Relocate Communications crate to M108. 19) Disconnect the GAB->TFW daughtercard and associated cables from the TAB/GAB crate backplane. Remove the L1CalTrk patch panel and cables from the sidewalk rack. Disconnect all cables along the front of the TAB/GAB crate (orange optical cables, white TFW/SCL cables, etc.). 20) Carefully thread the four bundles or trunks of LVDS cables through the open panel above the TAB/GAB crate. There are 240 cables in total, each with about 4.5 meters from the lock position of the strain relief system to the connector end (for the ADF). The four trunks of cables can be coiled up and gently placed inside a box or similar container. The weight of the cables needs to be supported so as not to drag on the TAB/GAB crate. 21) Remove the TAB/GAB crate from the sidewalk rack, and place it on a cart. The crate and cable combination moves uniformly to the steps leaving the sidewalk area, carried up the steps to another cart, and then rolled down to corridor to the MCH1 door. The crate is then carried by two people standing on both sides of the crate, with two people trailing along with the cable bundles. The center aisle is too narrow to permit a pair of people to rotate into position, so the crate needs to be carried down the aisle, with the rear facing south, so the TAB/GAB crate can slide into position along shelves into M107. 22) The four trunks of LVDS cables need to be threaded back to the rear of M107, and then routed to one of the four racks in which an ADF crate resides. The slack cable can be carefully stored on shelves in any of the racks which contain only patch panels. Reconnect the LVDS cables to the ATCs. 23) Route and connect the 160 pleated foil cables from the patch panel cards to the ATCs. The slack for the pleated foil cables can rest on the shelves behind each patch panel. Do not apply the strain relief latch on the patch panels yet. The pleated foil cables and BLS trigger cables share the same strain relief system, and it would be too time consuming to undo and redo one to two days later. 24) Set-up the test-wave generator for use in the MCH1. Turn on power to the ADF crates, and check out the pleated foil cables, patch panel cards, ATCs and ADFs. Have spares if any component fails the test. Turn off power after testing is completed. 25) Route, connect and redress the BLS trigger cables. For a given rack, 64 cables are in the left cable guide and 64 cables are in the right cable guide. There is plenty of open space in the shelves behind each patch panel to allow any slack BLS trigger cable to flow. 26) Use the Calorimeter pulser to check out BLS trigger cables with a scope and the monitor connectors on the front of each patch panel. We need a specially prepared cable and/or adaptor (and a spare?). To run the Calorimeter preamp pulser, the DAQ and Calorimeter readout is needed (trigger, preamp & BLS & pulser power, etc.). We may want to check out the first rack before doing the rest to determine if our handling of the cables has been too rough. 27) Reconnectorize cables that do not check out ok on the scope.
