1.0 INTRODUCTION

This specification is for the labeling of all cables in the Main Injector (MI) project. In general cables will be run from service building to service building (via the tunnel or the ducts in the road), service building to the tunnel, within a service building or within the tunnel. Typical origin/destinations will be relay racks, power supplies or elements in the tunnel.

2.0 SCOPE

The person in charge of the specific system in the Main Injector is responsible for giving to THE CABLE INSTALLATION MANAGER a list in an EXCEL file format with the cables they need pulled. The cable manager will assign cable numbers and print out the labels as requested well in advance of their need. THE CABLE INSTALLATION MANAGER will also be in charge of getting the cables pulled and in most cases getting the cables terminated

3.0 CABLE LABELS

The labels will have three lines. On the first line will be the CABLE TYPE/cable number and the FUNCTION. On the second line will be the ORIGIN. And on the third line will be the DESTINATION and MACHINE(BEAM LINE)/SYSTEM.

3.1 The CABLE TYPE/cable number will consist of six (6) characters and be assigned by THE CABLE INSTALLATION MANAGER.. The CABLE TYPE is the first two (2) characters of the serial number and is a (2) letter string that will be assigned by THE CABLE INSTALLATION MANAGER. Current assigned values are given in Appendix 1, Table 1. The last four (4) characters will be the serial number for this cable. This serial number will be assigned consecutively for each CABLE TYPE in the data base.

3.2 The FUNCTION code should be assigned by the requester and may be any six (6) character alpha-numeric string.

3.3 The ORIGIN and DESTINATION will be one of several choices. If the cable run is from relay rack to relay rack the ORIGIN will be the lower rack number of the two. If the cable run is from relay rack to tunnel the ORIGIN will be the relay rack. If the cable run is from tunnel to tunnel the ORIGIN will be the lower quad number. Additionally a particular power supply may be designated as the ORIGIN or DESTINATION. In the case of power supply to power supply cabling, an individual choice must be made for each occurrence. Sample ORIGIN and DESTINATION designations are given in Appendix 1, Table 2.

3.4 The MACHINE(BEAM LINE)/SYSTEM designator will be a two (2) letter string with the first letter representing the MACHINE(BEAM LINE) that the cable will be installed. Assigned MACHINE(BEAM LINE)designators are given in Appendix 1, Table 3. Additional assignments will be made by THE CABLE INSTALLATION MANAGER. The second character or SYSTEM will be a letter indicating the system that the cable is assigned. Assigned SYSTEM designators are given in Appendix 1, Table 4. Additional assignments will be made by THE CABLE INSTALLATION MANAGER.

3.5 If THE CABLE INSTALLATION MANAGER is required to terminate the cables, the requester will be required to also supply the ORIGIN and DESTINATION TERMINATION TYPE.

3.6 The maximum number of characters allowed for each field of the cable label will be:

CABLE TYPE/CABLE NUMBER 2(alpha)/4(numeric)

FUNCTION 6(alpha-numeric)

ORIGIN 13(alpha-numeric)

DESTINATION 10(alpha-numeric)

MACHINE(LINE)/SYSTEM 2(alpha)

TERMINATION TYPE not specified
