v Port 2 serves as the technician port when the system is initially set up or
when service is needed. In the figures, port 2 is identified by the blue
cable. After the system initializes, port 2 can also be used for iSCSI
connectivity or IP replication.
Note: Do not connect port 2 to a network switch until the system
initialization or service is complete. After the system initializes, the
technician port is automatically disabled and port 2 can be used for
Ethernet connectivity. However, when port 2 is used to perform system
service, you must first enter the satask chserviceip -techport disable
command to disable the technician port. You can then use port 2 to
provide additional Ethernet connectivity.
b. Connect Ethernet port 1 of each node canister in the system to the IP
network that will provide a connection to the system management
interfaces.
Figure 125 shows the Ethernet cabling and the ports on the back of a
Storwize V5010 system.
Figure 126 shows the Ethernet cabling and the ports on the back of a
Storwize V5020 system.
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 and
Figure 126. This second port can be used to provide a redundant connection
