c) Optionally, connect Ethernet port 2 of each node canister in the system to a second IP network, as
shown by the blue cable connection in Figure 125 on page 120 and Figure 126 on page 121. This
second port can be used to provide a redundant connection to the system management interfaces;
it can also be used for iSCSI connectivity to the system by hosts on the network.
Note: On Storwize V5010 or Storwize V5020 systems, the second Ethernet port is also used as the
technician port. Do not connect Ethernet port 2 to the SAN until the management GUI setup wizard
completes on each system and the cluster is created. If you have to service your system,
disconnect port 2 from the SAN before you enable port 2 to be the technician port again.
2. If you have a Storwize V5030 or Storwize V5030F system, complete the following steps.
a) Identify the location and function of the Ethernet ports on your system; refer to Figure 127 on page
121.
• The technician port should only be used to initialize or service the system. In Figure 127 on page
121, the technician port is identified by the green cable.
Note: Never use the technician port to provide an Ethernet connection to the system. Do not
connect the Ethernet technician port to a network switch. The technician port must only be
directly connected to a personal computer when initializing a system or servicing a node.
• Ethernet port 1 can be used to provide Ethernet connections. In the figure, port 1 is identified by
the blue cable.
• Ethernet port 2 can optionally be used to provide additional Ethernet connections. In the figure,
port 2 is identified by the red cable. Port 2 can also be used for iSCSI connectivity or IP
replication.
b) Connect Ethernet port 1 of each Storwize V5030 or Storwize V5030F node canister in the system to
the IP network that will provide a connection to the system management interfaces. Figure 127 on
page 121 shows the port locations and Ethernet cabling on a node canister.
