Step 7 unless the POST passed.
7. Cable N or NL_Port Adapters to the Switch
Ports
All 16 ports on the Switch may connect to N_Ports. Ports 1, 2, 5, 6, 9, 10, 13, and
14 may connect to NL_Ports or N_Ports. The type of media used (fiber optic
cable or copper) depends on the type of N or NL_Port adapters used and the type
of GBICs used in the Switch. You may populate the Switch with any assortment
of approved GBICs appropriate for your interconnection media type.

Tuning
You can optimize the system performance by connecting nodes which
interchange the greatest amount of traffic to ports on the Switch which are more
efficiently interconnected.
interchange the greatest amount of traffic to ports on the Switch which are more
efficiently interconnected.
Connect nodes which interchange the least amount of traffic to ports on the
Switch which are less efficiently interconnected.
Switch which are less efficiently interconnected.
The most efficient performance is within a group of four ports. These groups are:
Ports 1-4
Ports 5-8
Ports 9-12
Ports 13-16
Ports 5-8
Ports 9-12
Ports 13-16
When a frame source-port and destination-port are within the same port group,
you will realize:
you will realize:
The lowest Class 2/Class 3 frame latency
The highest Class 2/Class 3 point-to-point bandwidth
The highest Class 2/Class 3 aggregate bandwidth
The lowest Class 1 connect and disconnect latency — Class 1 frame
The highest Class 2/Class 3 point-to-point bandwidth
The highest Class 2/Class 3 aggregate bandwidth
The lowest Class 1 connect and disconnect latency — Class 1 frame
latency, point-to-point bandwidth, and aggregate bandwidth are not
affected by port groups, and are always the theoretical maximum.

When a frame source-port and destination-port are not within the same port group
the interconnection is slightly less efficient.
the interconnection is slightly less efficient.
Distance
The maximum distance between each adapter and the Switch depends on the type
of GBICs and the type of cable installed. Refer to the Reference Information in
Appendix A of this manual for this information. Also, the speed and Fibre
Channel Revision Level of each adapter must be compatible with the Switch and
the type of I/O media of each adapter must be compatible with the particular
GBIC on the Switch.

Hot-Pluggable
All GBICs and cables are “hot-pluggable”. That is, you may have the Switch
powered-up while you plug or unplug GBICs or cables of any interconnection
media type. Hot-swapping and unplugging does not affect other operating ports.
