Requirements and precautions
The cable management comb is attached to the chassis under the chassis door and allows for simple cable management. The comb can
be installed without service disruption.
Route the cables down in front of the blades to keep LEDs visible. Leave at least one meter of slack for each fiber optic cable to provide
room to remove and replace blades.
ATTENTION
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.
CAUTION
Before plugging a cable into any port, be sure to discharge the voltage stored on the cable by touching the electrical
contacts to ground surface.
The FC8-64 high density port blade cannot use the standard LC cables because the pitch between optics in the new 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. See "Best Practices Guide: High Density Cable Management Solutions"
(available at
http://www.brocade.com ) for cable management guidelines for high-density port solutions, cable and patch panel part
numbers.

3. 1.6 mm cable
4. SFP connector
Please note that the duplex clip on the mSFP end of the cable is black for easier recognition. See Qualified cables for the FC8-64 port
blade on page 48 for a listing of the qualified mSFP optical cables for the FC8-64 port blade.
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.
