Figure 12. Dual-Path Fibre Channel cabling
Do the following for each loop of storage expansion units:
1. Insert an SFP GBIC into the FC OUT port of upper controller A (IOM A) of the last disk storage
expansion unit in the loop of expansion units.
2. Insert an SFP GBIC into the FC OUT port of lower controller B (IOM B) of the last disk storage
expansion unit in the loop of expansion units.
3. Connect a Fibre Channel cable from the FC OUT port on the upper controller A of the last disk
storage expansion unit of the loop to FC port 0b of the lower processor controller module (CM-B) of
the N3400. See 3 in Figure 12.
4. Connect a Fibre Channel cable from the FC OUT port on the lower controller B of the last disk
storage expansion unit of the loop to FC port 0b of the upper processor controller module (CM-A) of
the N3400. See 4 in Figure 12.
Cabling example: HA (active/active) N3400 FC SAN configuration
This example shows a high-availability (active/active) N3400 Fibre Channel SAN cabling configuration.
For more N3400 cabling configurations, see the N3300, N3400, and N3600 Hardware and Service Guide.
