9. Are open ports on equipment free of obstruction for access in testing, system expansion or service work?
-
10. Are Power bricks, breakout blocks, and adapters placed on shelves or mounted to the rack frame?
-
11. Had the rule of thumb for rear rail placement, 6 to 8 inches from the deepest piece of equipment, been followed?
-
12. Is their sufficient space, with an average of one horizontal lacing bar per 2 pieces of gear, for technicians to access cable, connections, and perform testing?
-
13. Where applicable has the proper vent blocking been installed in the rack?
-
14. Has the main power strip been anchored to the chassis ground in the rack?
-
15. Did the technician take advantage of swapping in shorter power cords to reduce cabling congestion?
B.Labeling
-
1. Signal cables are labeled per Infocomm standards using machine printed labels and exactly as per shop wiring diagrams?
-
2. Power cables are marked as indicated on shop drawings (if applicable)?
-
3. Wall wart power supplies are labeled as to which item/s they are powering?
-
4. Label each rack for equipment type (Switcher,Amplifier,Controller etc.)
-
5. Label rack for each Room Name/Number as applicable.
-
6. Labeling for Rack should be both front and back. Front labels should be located on the right side,on the rack frame when possible,and on the individual equipment when necessary.Rear labels should be on the right,on the rear rails when possible, on the gear when necessary.This way labeling is retained if equipment is changed out at a later date.
C.Wiring & Harnessing
-
1. Low level signal cables that are susceptible to interference are installed on the right side of the rack (mic level,line level,video,low power RF)?
-
2. High level signal cables that can cause interference are installed on the left side of the rack (DC power,Rs232/422/485, speaker level, AC power)?
-
3. Cables are installed and combined neatly and dressed to support bars (no sagging)?
-
4. Cables come off lacing bars at 90 degrees but do not exceed bend radius?
-
5. Is it possible to easily remove individual equipment items for service (service loops,power dressed correctly)?
-
6. Equipment installed on slide assemblies have service loop on all cables to accommodate full travel of the slides?
-
7. Are grommets or bushings installed around cutouts and knockouts where conduit or chase nipple are not installed?
-
8. Are brush panels installed for any cables pentrating the front of the rack?
-
9. Tie wraps reqularly spaced,rotated the same way,not over-tightened and cut flush?
-
10. Parallel or jumpered wire connections are made at terminal blocks (no wire nuts)?
-
11. Patch bays installed and wired person drawings?
-
12. Has sleeving being properly installed? (Anchor points to prevent pull out, no tape used)
-
13. Is the shrink wrap used for connections of uniform length?
-
14. Do all dress edges of cable connections have shrink wrap?
-
15. Is clear shrink used on all ground connections?
-
16. Do the Phoenix connection tabs (Biamp mic connections for example) have the “nub” on the underside of the connector tab?
-
17. Are Velcro ties used on the Data & HD video cables?
D. Terminations (random Checks)
-
1.Solder joints will meet the following criteria:
-
A. Final solder joint will be bright and shiny and show no evidence of being cold a " cold joint".
-
B. No bare wire will be exposed within the connection.
-
C. All solder Joints will "wet" and flow around conductors and terminations. In no case will the general outline of the conductor be invisible due to excessive solder.
-
D. The joint will be free of contamination from foreign matter.
-
E. Heat shrink is used per Infocomm Standards.
-
F. Insulation/heat shrink will not be charred,melted,or burned by the soldering operation.
-
2. Crimp connections will meet the following criteria:
-
A. Terminal lug not cracked.
-
B. No insulation in the wire barrel.
-
C. Terminal insulation not cracked.
-
D. No wire stands nicked or lost.
-
E. Wire stripped to the correct length and positioned in the crimp Barret so the strands protrude slightly from the barrel.
-
3. Captive wire Connectors will meet the following criteria:
-
A. Use stranded wire only.
-
B. Strip individual stranded wire so that 1/16th-inch of wire is visible beyond the connector.
-
4.BNC connectors will meet the following criteria:
-
A. No exposed braid.
-
B. Physical integrity (cannot pull connectors off the cable).
-
5.Connections of audio shields:
-
A. For line level balanced audio signals,wire according to the shop wiring diagrams. Any shield not connected should be folded back over the cable jacket and secured with tie wrap/ heat shrink. Do not cut off unused shield.
-
B. Microphone level signals will always have the shield connected on both ends.
-
C. Cable harness for inter rack connections will be manufactured in the shop.One end will be the anchor side (normally the side with the most connections). The other end will be the one designed to be unplugged and rolled up when the system is shipped out. The goal is to make the harness "plug and play" for the installers once system reaches the field.
E. Rack Power
-
1. Plastic Power strip are not used.
-
2. "Wall Warts" will be securely fastened to AC strips using tie wraps (use of wall warts should be minimized by engineers specify appropriate power distribution products where these exist).
-
3. Verify that un-switched power is provided to components as identified on shop wiring diagram.
-
4. Verify that switch power is provided to components as identified on shop wiring diagram.
-
5. The only power cable exiting the rack and plugging into the wall shall be the input to the power conditioner. Power strips within the rack shall be fed from the power conditioner.
-
6. Plug the rack in and verify that all equipment powers up.
-
7.Dress power first to insure everything fits & we can verify plug count for power. Engineering has added power flows to drawings be sure to review these prior to installing and dressing power.
-
8. Individual power dressed with bow tie for separate isolation,accessible, and charge outs. Do not bundle power cables in harness.
