Managing cables
Cables can be organized and managed in a variety of ways: for example, using cable channels on
the port sides of the cabinet or patch panels to minimize cable management. With the horizontal
orientation of the blades in the Brocade DCX 8510-4, a pair of vertical cable management finger
assemblies have been provided to keep the cables from hanging down in front of other blades.
Following is a list of recommendations:
•
Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to remove and
replace the Brocade DCX 8510-4, allows for inadvertent movement of the rack, and helps
prevent the cables from being bent to less than the minimum bend radius.
•
The minimum bend radius should be no smaller than 10x the cable radius. The minimum
radius to which a 50 micron cable can be bent under full tensile load is 5.1 cm (2 in.). For
a cable under no tensile load, that minimum is 3.0 cm (1.2 in.).
•
If ISL Trunking is in use, group the cables by trunking group. The ports are color-coded to
indicate which ports can be used in the same ISL Trunking group: eight ports marked with
solid black ovals alternate with eight ports marked with oval outlines.
•
Generally, Velcro
®
type cable restraints are recommended to avoid creating sharp bends
in the cables. Do not use tie wraps with optical cables because they are easily
overtightened and can damage the optic fibers.
•
For easier maintenance, label the fiber optic cables and record the devices to which they
are connected.
•
Do not route cables in front of the air exhaust vents.
•
Route the cables to the sides of the Brocade DCX 8510-4 through the vertical cable
management fingers.
•
Keep LEDs visible by routing port cables and other cables away from the LEDs.
