Cable Routing and Bundling

Cable Routing and Bundling

This section describes the general methods and requirements for cable routing and bundling.

Cable Routing

  • In an equipment room containing brackets and an ESD floor, cables can go through the interlayer (the space between the concrete floor and the ESD floor) or the cable trough. If the cables are led out from the top of the cabinet, a cable tray should be built over the cabinet.
  • The specifications, routing, section, and position for arranging the cables should be predesigned. The cables should be lined up neatly, without damaging the cover.
  • The cable should be turned smoothly at the bends, with a minimum bend radius of three times the diameter of the cable.

Bend the mini SAS HD cables at a radius at least 35 mm (1.38 in.). The exposed length of the mini SAS HD cables must be at least 70 mm (2.76 in.), as shown in Figure D-1

Figure D-1 Routing cables before placing them into the cable trays

  • If cable trays are installed for a storage device, place all cables connected to the device into the troughs of the cable trays.
  • Evenly divide the cables connected to the storage device into two groups. Place the left group of cables into the troughs of the left cable tray, and the right group into those of the right.
  • Mini SAS HD electrical cables must be bound before being placed into the troughs of the cable trays. Bind the cables with the power cables onto the handles of the fan modules, then place them and the ground cables into the troughs of the cable trays, as shown in Figure D-1.
  • The insulation layer of the conducting wire must be intact.
  • Easy maintenance and expansion should be considered when cables are routed.

Cable Bundling

  • Bind the cables when laying them on the passage. The cables should be aligned snugly together. The spacing between the cable ties should be even with a neat overall appearance.
  • Cables running through a trough need not be bound but should be arranged neatly and without crossover. The cables should not overflow the trough. Bind or attach the cables with ties where they enter or exit the trough and at turning points.
  • The bundles should be tidy, clear, and elegant. The bundles can be classified by type. A large number of cables can be further classified by column. Bind each group of cables with ties.
  • All cables must be bound properly to prevent cable loosening or damage.
  • Do not connect two or more cable ties to bind cables, as this may decrease the strength of the bundling.
  • Bind the cables neatly and trim the excessive tie.
  • The cable ties should be evenly spaced three to four times the diameter of the cable bundle.
  • Use as long a bend radius as possible to prevent internal cable stress and breakage.

Figure D-2 shows how to bind cables.

5. Cable ties correctly trimmed

6: Cables are bundled at an even interval, which is three or four times the diameter of the cable bundle
