1U = 1.75 in
One Quadrant of CMS EE has xx full supercrystals and xx specials, =
78 total per quadrant = 156 per Dee
Supercrystals are supplied using 51way Redel SLG.H51 connectors. One
connector supplies 12 Supercrystals, so 13 bunched coax cables ("looms") are
required per Dee.
This means 26 cables per rack
If the distribution boxes are arranged in quadrants, this means 7
looms per box (sort of)
Or, if the distribution boxes are arranged in octants(?) this means 4
looms per box (sort of)
etc etc...
Our racks are S2B09 and S2G09 (actually I think this
may have changed!)
