Installing the cable management pillars (optional)
Use cable management pillars (shown in Figure 28) to organize the port cables into logical groups,
such as according to port groups. The cable management pillars do not attach to the chassis and
their use is optional.
NOTE: Cable pillars are not supported when using the FC4-32 or FC4-48 port blades because the
cable count is too dense, leaving no room for the cable pillars. Instead, you should use velcro tabs
to group cables for the FC4-32 or FC4-48 port blades
To use the cable management pillars, insert the cables into the holes in the guides, using a separate
hole for each cable.
Figure 28 Cable management pillar
You can manage cables in a variety of ways: you may be route them down through the cable
management comb or out from either side of the chassis; you may also use 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 down, instead of across adjacent cards, or in front of the
power supplies.
Leave at least one meter of slack for each fiber optic cable when you connect them. This provides
room to remove and replace port blades, 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 pillars provided with the SAN Director to group the cables by trunking ports (groups
of four or eight neighboring ports). The cable pillars help to keep individual ports accessible by
keeping the cables evenly spaced.
