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 vertical orientation of the blades in the Brocade DCX 8510-8, a cable management comb is provided below the blades on the
port side.
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 device, 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 ten times 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 bers.
• For easier maintenance, label the ber-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 bottom of the Brocade DCX 8510-8 through the cable management comb.
• Keep LEDs visible by routing port cables and other cables away from the LEDs.
