Configuring the Fibre Channel port

The N3700 storage system CPU module provides two independent Fibre Channel

ports, identified as B and C:

v You use the B port to communicate to the expansion unit.

v The C port has an external optical connector on the rear of the N3700 storage

Note: For N3700 storage systems with the current CPU module design, you must

Fibre Channel port C does not support mixed initiator/target mode. The default

mode for port C is initiator mode. You do not need to configure the port.

N3700 storage system active-active (clustered) configurations must be cabled to

switches that support public loop topology. To connect an N3700 storage system to

a fabric topology that includes switches that only support point-to-point topology,

such as McDATA Director class switches, you must connect the active-active

(clustered) configuration to an edge switch and use this switch as a bridge to the

fabric. For information about specific switch models supported and fabric

configuration guidelines, see the IBM System Storage N series Data ONTAP Block

Access Management Guide for your version of Data ONTAP at the following Web

system. You can configure the C port to be used in initiator mode to

communicate with tape backup devices, such as in a TapeSAN backup

configuration.

plug an SFP module into port C before cabling or terminating it. Port C is the

leftmost port on the bottom CPU module.
