EMC Connectrix B Series ED-48000B Hardware Reference Manual
To keep LEDs visible and make it easy to replace components, route
cables down in front of the blades, not across adjacent blades or in
front of the power supplies.
in which cables for each blade are routed in front of that blade and are
out of the way of other components.
Leave at least 1 meter of slack for each fiber-optic cable. This provides
room to remove and replace the port blade, allows for inadvertent
movement of the rack, and helps prevent the cables from being bent
to less than the minimum bend radius.
Use the cable guides provided with the ED-48000B to group the
cables. These guides help to keep individual ports accessible by
keeping the cables evenly spaced. If ISL Trunking is in use, grouping
the cables by trunking group is recommended. The ports are
color-coded to indicate which ports can be used in the same ISL
Trunking group: four ports marked with solid black ovals alternate
with four ports marked with oval outlines.
Note: ISL Trunking is an optional Fabric OS feature that enables distribution
of traffic over the combined bandwidth of up to eight ISLs between two
directly adjacent switches, while preserving in-order delivery.
A minimum length is required for cables that connect the ED-48000B
ports to device ports, as described in
