Connecting Ethernet cables to node canisters
To provide system management connectivity for your Storwize V3700 system, you
must connect Ethernet cables to Ethernet port 1 of each node canister in the control
enclosure. This connection can optionally also be used for iSCSI host connection.
Ethernet port 2 can optionally be connected to provide a second system
management address, a second iSCSI host connection, or both.
Procedure
To install the Ethernet cables, complete the following steps.
1. Connect Ethernet port 1 of each node canister in the system to the IP network

Figure 30. This port can also be used for iSCSI connectivity to the system by
hosts on the network. Where more than one control enclosure is present in the
system, ensure port 1 of every node canister is connected to the same network
to provide access if the configuration node fails.
