right in the lower group of 12 ports. They are labeled FC on the front panel diagram. The
two 10-GbE ports are 0 and 1 and are in the left-hand column above the FC ports. They are
labeled 10GE on the front panel diagram. The 1-GbE ports are 0 through 9 and are in both
columns above the FC and 10GE ports. They are labeled GE on the front panel diagram.
There are three FC trunking groups, defined as follows:
◦ Trunk group 0: FC ports 0, 1
◦ Trunk group 1: FC ports 6, 7
◦ Trunk group 2: FC ports 2, 3, 4, 5, 8, 9, 10, 11
• FCOE10-24 blade—Ports are numbered from 0 through 23 in two vertical rows, starting from
the bottom left and ending at the top right.
Managing cables
NOTE: The minimum bend radius for a 50 micron cable is 2 inches under full tensile load and
1.2 inches with no tensile load.
NOTE: The FC8-64 high density port blade cannot use the standard LC cables because the pitch
between optics in the new mSFP optical transceiver is smaller than in the standard SFPs. Patch
cables and panels can be used to attach standard size cabling to the blade if necessary.
Figure 13 (page 30) shows the mSFP to SFP patch cable. See Best Practices Guide: High Density
Cable Management Solutionsfor cable management guidelines for high-density port solutions,
cable and patch panel part numbers. The duplex clip on the mSFP end of the cable is a different
color for easier recognition. See Table 3 (page 17) for a listing of the qualified mSFP optical cables
for the FC8-64 port blade.

A pair of vertical cable management finger assemblies provide routing paths to prevent cables
from hanging down in front of other blades. See Figure 14 (page 31).
Follow these cabling guidelines:
• Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to remove and
replace the switch.
• If ISL Trunking is used, 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.
• For easier maintenance, label the fiber optic cables and record the devices to which they are
connected.
