Recommendations for Cable Management
■
You can manage cables in a variety of ways, such as routed down through the
cable management tray or routed out either side of the chassis, and by using
patch panels or cable channels on the sides of the cabinet.
■
To keep LEDs visible and prevent having to disconnect cables when
removing neighboring cards, route fiber optic and other cables directly
downwards, instead of across adjacent cards or in front of the power supplies.
■
Leave at least one meter of slack for each fiber optic cable. This provides
room to remove and replace the port card, 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 for a 50 micron cable is 2
inches under full tensile load and 1.2 inches with no tensile load).
■
Use the cable guides provided with the Core Switch 2/64 to group the cables
by trunking ports (groups of four neighboring ports). These guides help to
keep individual ports accessible by keeping the cables evenly spaced, and also
help to provide clearance for the removal of a neighboring card.
