High-Density Cabling - Brocade Communications Systems Backbone DCX 8510-8 Hardware Reference Manual

High-density cabling

CAUTION
Before plugging a cable into to any port, be sure to discharge the voltage stored on the cable
by touching the electrical contacts to ground surface.
• Plan for rack space required for cable management before installing the switch.
• Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to remove and replace
the switch, allows for inadvertent movement of the rack, and helps prevent the cables from being
bent to less than the minimum bend radius.
• If you are using Brocade ISL Trunking, consider grouping cables by trunking groups. The cables
used in trunking groups must meet specific requirements, as described in the Fabric OS
Administrator's Guide .
• For easier maintenance, label the fiber-optic cables and record the devices to which they are
connected.
• Keep LEDs visible by routing port cables and other cables away from the LEDs.
• Use Velcro
NOTE
Do not route the cables in front of the air exhaust vent, which is located at the top of the port side of
the chassis.
High-density cabling
The FC8-64 high density port blade cannot use the standard LC cables because the pitch between
optics in the new mini-SFP (mSFP) transceiver is smaller than in standard SFPs. Patch cables and
panels can be used to attach standard size cabling to the blade if necessary. The following figure
illustrates the mSFP to SFP patch cable. Refer to "Best Practices Guide: High Density Cable
Management Solutions" (available at
high-density port solutions, and cable and patch panel part numbers.

Note that the duplex clip on the mSFP end of the cable is black for easier recognition. Refer to

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.
